When ccache is on PATH, prefix CC/CXX with it so every compile goes through
ccache -- no Makefile change, since rules.mak already runs `${CC} ... -c` and
defs.mak substitutes @CC@/@CXX@. Autodetected on by default; --disable-ccache
opts out.
Placed after the AC_PROG_C* checks so configure's own feature tests use the
plain compiler and only the build picks up the prefix. Pairs with the
build-info isolation (utils/buildinfo.c): with the volatile MAGIC_BUILDDATE on
only that one unit, a full rebuild hits the cache for every other unit.
Measured (default Tcl build, all objects deleted then rebuilt): 323/324 hits
with the date enabled (only buildinfo.o misses), 324/324 with
--disable-magic-builddate.
Verified: default configure -> CC="ccache gcc", CXX="ccache g++";
--disable-ccache -> CC="gcc".

New configure option --disable-magic-builddate omits the build date from the
binary. It is wired via an AC_SUBST'd MAGIC_BUILDDATE_DEFS (not AC_DEFINE), so
it reaches only buildinfo.o rather than @DEFS@ / every command line:
* enabled (default): buildinfo.o gets -DMAGIC_BUILDDATE="<date>" and defs.mak
computes the date (SOURCE_DATE_EPOCH-aware);
* disabled: buildinfo.o gets -DMAGIC_NO_BUILDDATE instead, defs.mak skips the
date computation entirely (no parse-time `date` spawn), and buildinfo.c
reports an empty MagicCompileTime.
This gives a fully reproducible build whose one volatile input (the date) is
gone; what remains in buildinfo.o is commit/version/revision, which do not
change second-to-second -- the intended pairing with ccache for day-to-day
development.
Verified both configs: default bakes the date + commit; --disable-magic-builddate
compiles buildinfo.o with -DMAGIC_NO_BUILDDATE (no date), commit still present.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
MAGIC_BUILDDATE now derives from SOURCE_DATE_EPOCH (UTC) when it is set,
falling back to the current local time otherwise. This makes the date baked
into buildinfo.o reproducible for the appimage/npm tarballs (cf. npm/pack.sh,
which already normalizes mtimes).
Also add `2>/dev/null` to the MAGIC_COMMIT git call so a source tarball or a
non-work-tree ${MAGICSRC} yields an empty commit rather than a git error.
Only buildinfo.o consumes these (see the prior commit), so the shell still
runs at defs.mak parse time but affects just that one unit's define.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
MAGIC_VERSION / MAGIC_REVISION / MAGIC_COMMIT / MAGIC_BUILDDATE were on the
global DFLAGS, so every object's compile command line carried them. Because
the command line is part of ccache/sccache's hash key and MAGIC_BUILDDATE
changes every second, that meant a cache miss on every unit on every build;
it also smeared the baked-in date/commit across "whenever each file last
recompiled".
Move the four values into a single translation unit:
* utils/magic_buildinfo.h -- extern MagicVersion/MagicRevision/MagicCommit/
MagicCompileTime (MagicCommit is new; the other three moved here from
utils/magic.h, which now includes this header).
* utils/buildinfo.c -- the ONLY unit compiled with the version defines
(target-specific `buildinfo.o: DFLAGS += ${DFLAGS_MAGICVERSION}` in
utils/Makefile.in); it defines the four globals. ${DFLAGS_MAGICVERSION}
is removed from the global DFLAGS/DFLAGS_NOSTUB.
Consumers updated to read the runtime symbol instead of the compile-time
macro:
* magicTop.c / tclmagic.c no longer define the globals (the MAGIC_WRAPPER
duplicate-symbol guard is gone -- buildinfo.o owns them for every variant,
including WASM, which links both mains).
* Tcl_PkgProvide/PkgRequire in router/ext2spice/lef/ext2sim/plot/tclmagic
now pass MagicVersion.
* extflat: EFVersion (a static-initialized copy of MAGIC_VERSION) is dropped;
EFread.c compares the .ext version against MagicVersion directly -- the same
value ExtCell.c already *writes* into .ext files, so read and write are now
consistent.
Verified: only buildinfo.o carries -DMAGIC_* (hash/DBio/windCmdSZ carry none);
Tcl (375 files) and --without-tcl builds rc=0, version/commit/date embedded in
tclmagic.so, magicTop.o no longer defines MagicVersion; in-tree source clean.

rules.mak has no @...@ substitutions, so there is no reason to copy it into
the build top. Point all 38 subdir Makefile.in includes at the source copy
directly -- ${MAGICSRC}/rules.mak instead of ${MAGICDIR}/rules.mak -- and
remove AC_CONFIG_FILES([rules.mak:rules.mak]) from configure. defs.mak (the
one make fragment with substitutions) remains the only generated file in the
build top. readline/ and the top Makefile never included rules.mak, so they
are unaffected; AC_CONFIG_SRCDIR(rules.mak) (the srcdir sentinel) is kept.
Now editing rules.mak in the source tree takes effect without reconfiguring.
Verified rc=0, 375 files, both in-tree and out-of-tree; out-of-tree build
top has no rules.mak; distclean rc=0.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Every converted module sets srcdir=@srcdir@ and VPATH=@srcdir@
before including defs.mak, so the full srcdir derivation is now reached
only by readline/ (never converted) and the top-level Makefile. Neither
compiles magic sources through the pattern rules, so neither needs VPATH.
Drop the MODULE_SUBPATH variable and the VPATH derivation; keep just a
one-line srcdir fallback so CPPFLAGS (-I${srcdir}) stays well-formed for
those two. BUILD_TOP is retained (GENINC still needs it).
Verified rc=0: out-of-tree Tcl (375) + in-tree Tcl (375, header present) +
out-of-tree --without-tcl (readline/libreadline.a + magic/magic built
through the fallback).

Convert the last nested children to Makefile.in and switch their parents
from the -f fallback to native recursion (they now have generated build
Makefiles). Rename and rewire are one unit: a pure rename would break the
parent's -f path to the (now-.in) child.
Converted (5): scmos/cif_template, doc/man, doc/tutcells, doc/html,
doc/latexfiles. Pure renames -- still build via the srcdir derivation;
@srcdir@ substitution follows.
Rewired to native `make -C <child>` (config.status now creates the child
build dirs + Makefiles):
* scmos/Makefile.in: cif_template build + clean.
* doc/Makefile.in: install/install-tcl over man/tutcells/html/latexfiles.
* Makefile.in: the docs: target -> `make -k -C doc/latexfiles all`.
The `mkdir -p` and `-f ${MAGICSRC}/.../Makefile` are dropped in each.
* configure.in: AC_CONFIG_FILES for the 5 children; regenerated configure.
* .gitignore: ignore each generated child Makefile, same commit.
Verified out-of-tree: full `make && make install` rc=0, 376 files --
scmos recurses natively into cif_template (8 objs), docs regenerate via
native doc/latexfiles (27/28), man pages install via native doc/man.

Fourth batch of the Makefile.in migration: the top-level complex outliers
magic tcltk scmos doc lisp
Pure renames -- content unchanged, so each still builds via the defs.mak
srcdir derivation; the @srcdir@ substitution follows.
Their nested children (scmos/cif_template and doc/{man,tutcells,html,
latexfiles}) are intentionally NOT converted here: scmos and doc recurse
into them with `-f ${MAGICSRC}/.../Makefile`, which keeps working only
while those children remain static Makefiles. They convert in a later
step together with the parent-recursion updates.
* git mv <dir>/Makefile -> <dir>/Makefile.in (5 modules)
* configure.in: AC_CONFIG_FILES for each; regenerated configure.
* .gitignore: ignore each generated <dir>/Makefile, same commit.
Verified out-of-tree: full `make` rc=0 -- tclmagic.so, scmos techs (scmos
recurses into the static cif_template via -f, 8 objs), 27/28 docs.

Third batch of the Makefile.in migration: near-standard modules
(utils windows commands database) and the program/.so outliers
(lef plot router ext2spice ext2sim extcheck net2ir graphics oa).
Pure renames -- content unchanged, so each still builds via the defs.mak
srcdir derivation; the @srcdir@ substitution follows.
* git mv <dir>/Makefile -> <dir>/Makefile.in (13 modules)
* configure.in: AC_CONFIG_FILES for each; regenerated configure.
* .gitignore: ignore each generated <dir>/Makefile, same commit.
These modules carry sibling-object refs (${MAGICDIR}/<mod>/lib*.o) and
custom rules; those keep working unchanged (${MAGICDIR} = the build top,
$(srcdir) from the derivation). readline/ remains on the -f path.
Verified out-of-tree: config.status writes 35 module Makefiles (22 + 13);
`make modules libs` builds all 33 module libraries (rc=0).

Pure renames -- content unchanged, so each still builds via the defs.mak
srcdir derivation (dual mode); the @srcdir@ substitution follows.
* git mv <dir>/Makefile -> <dir>/Makefile.in (21 modules)
* configure.in: AC_CONFIG_FILES for each; regenerated configure. Their
build subdirs + Makefiles are now created by config.status, so
$(submake) recurses natively (make -C <dir>), no -f.
* .gitignore: ignore each generated <dir>/Makefile, in this same commit.
Verified out-of-tree: config.status writes 22 module Makefiles (these 21 +
tiles); `make modules` builds all 33 module libraries (rc=0).

First module of the Makefile.in migration (proof). Pure rename: the
Makefile content is unchanged, so config.status just copies it and the
module still builds via the defs.mak srcdir *derivation* (dual mode from
phase 1) -- the @srcdir@ substitution is a separate follow-up.
* git mv tiles/Makefile -> tiles/Makefile.in
* configure.in: AC_CONFIG_FILES([tiles/Makefile:tiles/Makefile.in]);
regenerated configure. config.status now creates build/tiles/Makefile,
so $(submake) recurses into tiles natively (make -C tiles), no -f.
* .gitignore: ignore the generated tiles/Makefile (in-tree it lands in the
source tree) -- added in this same commit so it can never be committed.
Verified out-of-tree: config.status writes build/tiles/Makefile,
make -C tiles module builds libtiles.o (rc=0).

Enabler for the Makefile -> Makefile.in migration. No module is
converted yet; behaviour is identical.
* scripts/defs.mak.in: dual-mode. A module converted to Makefile.in will
set `srcdir` (and VPATH) from @srcdir@ before including defs.mak; only
derive them (the $(abspath)/$(patsubst) srcdir computation) when it
did not -- `ifeq ($(origin srcdir),undefined)`. BUILD_TOP (needed by
GENINC) is computed either way.
* Makefile.in: route every subdir recursion through a single helper,
$(call submake,<dir>,<goal>)
which uses the generated build Makefile if config.status made one there
(a converted Makefile.in) and otherwise falls back to the source
Makefile with -f. Today nothing is converted, so out-of-tree always
takes the -f path and in-tree uses the (identical) static Makefile
natively. clean/ keeps its own no-mkdir variant. readline/ is
intentionally never converted and always takes -f.
* .gitignore: document the migration policy -- each converted module adds
its generated "<dir>/Makefile" here in the same commit so an in-tree
build can never commit a generated Makefile. (None converted yet.)
Verified in-tree and out-of-tree: `configure && make && make install`
each produce 376 files with the header in the right place (database/
database.h in-tree, include/database/database.h relocated), 27/28 docs,
source tree clean.

Emit an autoconf config header carrying every autoconf define -- at least
all the -D options that appear on the compiler command lines, plus
anything else configure knows -- available to the tree as
#include <magic/autoconf/config.h>
It is built directly from confdefs.h just before AC_OUTPUT (which removes
that file), NOT via AC_CONFIG_HEADERS. This is deliberate:
* AC_CONFIG_HEADERS would rewrite @DEFS@ to -DHAVE_CONFIG_H and move the
defines into the header, changing every compiler command line and
breaking the build until sources #include it. Building from confdefs.h
leaves @DEFS@ (and the whole build) exactly as-is, so the header is a
pure additional artifact with no consumers yet.
* confdefs.h already holds every AC_DEFINE, including the many that have
no autoheader template (CALMA_MODULE, HAVE_READLINE, ...), which
AC_CONFIG_HEADERS/autoheader would have dropped.
Location mirrors the generated database.h (defs.mak GENINC): magic/autoconf/
config.h at the build top when in-tree (build dir == source dir), else
include/magic/autoconf/config.h so the clean -I include/ rule finds it and
the raw build dir stays off the search path. The directory is created on
demand and the header is rewritten on every ./configure. No defs.mak.in
change is needed -- the existing -I${GENINC} already resolves it.
.gitignore: ignore the in-tree magic/autoconf/config.h (out-of-tree it is
under the build dir and already ignored).
Verified: out-of-tree writes include/magic/autoconf/config.h, in-tree
writes magic/autoconf/config.h; both contain the command-line defines
(SIZEOF_VOID_P, CALMA_MODULE, HAVE_*, ...); #include <magic/autoconf/
config.h> resolves via -I${GENINC} from a subdir; @DEFS@ is unchanged
(-DHAVE_CONFIG_H absent) and modules still build.

Previously the generated database/database.h was written to the build
top and exposed with -I${MAGICDIR}. Out-of-tree that placed the raw
build directory on the compiler's include search path.
Introduce ${GENINC}, the single include dir for generated headers:
* in-tree (build top == source top): ${MAGICDIR}, so the header stays
at $(builddir)/database/database.h and -I${GENINC} is exactly the old
-I${MAGICDIR} -- behaviour is unchanged.
* relocated (out-of-tree): ${MAGICDIR}/include, so the header is written
to $(builddir)/include/database/database.h and only that clean
include/ dir is on the search path; the raw build top never is.
* scripts/defs.mak.in: derive GENINC from BUILD_TOP vs MAGICSRC; add
DATABASE_H = ${GENINC}/database/database.h; CPPFLAGS uses -I${GENINC}.
* Makefile.in: the makedbh rule targets ${DATABASE_H} (mkdir its dir);
every prereq and the distclean use ${DATABASE_H}.
* database/Makefile: the fallback delegate targets ${DATABASE_H}.
Verified: relocated `make modules` builds all 33 module libraries with
the header at build/include/database/database.h and no raw build-top on
any -I line; in-tree the header stays at database/database.h and the
-I set is unchanged.

The non-Tcl ("standard") configuration links the bundled GNU readline,
and that path was broken two ways:
* headers: readline's own headers use <readline/*.h> includes, so the
readline source's parent must be on the include path. Nothing added
it, so every module including readline (commands, textio, ...) failed
with "readline/rlstdc.h: No such file". Add -I${MAGICSRC}/readline to
CPPFLAGS for the bundled build only (@MAKE_READLINE@ = 1).
* library: readline/Makefile ran "../readline/configure" from the
build-readline dir -- a source-relative path that, out-of-tree, points
into the (empty) build tree. Use ${MAGICSRC}/readline/readline/
configure so the out-of-source readline build finds its sources.
Verified: `mkdir b; cd b; ../configure --without-tcl && make` now
completes (rc=0) and produces the native magic binary; previously it
died at commands/CmdFI.o (headers) then at the readline library build.

When latex and dvips are available, the default no-arg "make" now
regenerates the PostScript documentation from its .tex sources into the
build tree; otherwise the pre-built PostScript shipped in the source tree
is used as-is at install time. Documentation is always available either
way -- installing latex simply refreshes it from source.
configure (scripts/configure.in, regenerated scripts/configure):
* AC_PATH_PROG for latex + dvips; DOCS_TARGET = "docs" only when both are
found; AC_SUBST(LATEX/DVIPS/DOCS_TARGET).
* Configuration summary prints "LaTeX docs: yes/no".
scripts/defs.mak.in: export LATEX/DVIPS.
Makefile.in:
* all: ... $(DOCS_TARGET) -- pulls in "docs" only when latex was found.
* docs: best-effort -- `make -k` + a warning on failure so a document
that will not typeset (or a missing texlive package) never fails the
build; install falls back to the pre-built PostScript for those.
doc/latexfiles/Makefile:
* use ${LATEX}/${DVIPS} from defs.mak.
* the .tex include figures as ../psfigures/*.ps; point the build-tree
../psfigures at ${MAGICSRC}/doc/psfigures (no-op in-tree) so latex and
dvips find them while outputs stay in the build tree.
CI: main.yml and main-aarch64.yml install
texlive-latex-base/-recommended + texlive-fonts-recommended so the Linux
builds exercise doc regeneration (best-effort, never fatal).
README.Tcl: document latex/dvips as an optional prerequisite for docs.
.gitignore: ignore in-tree doc build artifacts (doc/latexfiles/psfiles/,
*.dvi/*.aux/*.log); the pre-built doc/psfiles/ stays tracked.
Verified out-of-tree with TeX Live 2024: configure reports "LaTeX docs:
yes"; `make` regenerates 27/28 documents into the build tree (maint1.tex
has a genuine LaTeX error and falls back), stays exit 0; `make install`
installs the 27 regenerated PostScript from the build tree and maint1
from the source pre-built copy; the source tree is not modified.

Fix the remaining non-standard Makefiles so a full out-of-tree
`../configure && make && make install` builds and installs a complete
magic TCL tree, sources read from the source tree, all outputs in the
build tree.
Shared linker/preprocessor paths (scripts/configure.in, regenerated
scripts/configure):
* --version-script=${MAGICDIR}/magic/symbol.map -> ${MAGICSRC}/... so
every shared-library link (tclmagic.so, ...) finds the source map.
* MCPP preproc.py path ${MAGICDIR}/scripts -> ${MAGICSRC}/scripts.
Programs (built via tcllibrary, PROGRAMS = magic tcltk):
* magic/Makefile: proto.magicrc, magicWasm.o and the bitmaps/.initrc/
magicps.pro install copies use $< / $(srcdir) instead of bare names.
* tcltk/Makefile: magicexec/magicdnull compile $<; the sed'd launcher
scripts (magic.tcl/.sh, ext2spice.sh, ext2sim.sh) read $<; VERSION dep
-> ${MAGICSRC}; install-tcl copies each TCL file from the build dir if
present else $(srcdir) (magic.tcl is generated, the rest are source).
Techs (scmos):
* scmos/Makefile: SC_PP template include -> $(srcdir)/extract_template;
tech-file inputs (scmos.tech.in, *.tech.in) via $(srcdir)/$< ; recurse
into cif_template with mkdir + -f ${MAGICSRC}/scmos/cif_template/Makefile;
install copies from build-or-$(srcdir).
* scmos/cif_template/Makefile: MKDIR -> ${MAGICSRC}/scripts/mkdirs;
SC_CPP gains -I$(srcdir); cpp reads $(srcdir)/cif{in,out}.c so the .gen
includes resolve; objs/ generated in the build tree.
Data-file installs (source files copied from $(srcdir)):
* graphics/Makefile: glyphs, outline fonts, and the X11 helper build.
* windows/Makefile: glyphs and vector fonts.
* doc/Makefile: recurse into man/tutcells/html/latexfiles build-aware;
doc/man, doc/tutcells install with $< ; doc/html tars $(srcdir);
doc/latexfiles reads pre-built PostScript from ${MAGICSRC}/doc/psfiles.
Verified out-of-tree (mkdir _build; cd _build; ../configure): `make`
returns rc=0 (33 module libs, tclmagic.so, magicexec/magicdnull, scmos
tech files + cif_template objs, proto.magicrc), and
`make install DESTDIR=...` returns rc=0 installing 376 files
(bin/magic, tcl/tclmagic.so, sys/ glyphs+fonts+techs+dstyles), with the
source tree left completely clean.
Not exercised by the default TCL build/install and therefore not
converted here: the standalone .so/program variants of
lef/plot/router/ext2spice/ext2sim (their module libs do build), the
disabled oa module (-I. -> -I$(srcdir) still needed if enabled), the
WASM path, and doc/latexfiles PostScript *regeneration* (which still
writes into the source psfiles dir).

Make a plain `make` in a build directory build every module into the
build tree. The top Makefile becomes a configure-generated Makefile.in,
and each recursion drives a build subdirectory (created on demand) using
the module Makefile from the source tree.
Makefile -> Makefile.in (config.status generates Makefile in the build
top via AC_CONFIG_FILES([Makefile:Makefile.in])):
* Add MAGICSRC = @abs_top_srcdir@; read VERSION and re-run configure from
${MAGICSRC}.
* Every descent `(cd $$dir && ${MAKE} <goal>)` and `${MAKE} -C $(dir $@)
<goal>` becomes:
mkdir -p <builddir> && ${MAKE} -C <builddir> \
-f ${MAGICSRC}/<dir>/Makefile <goal>
so the build subdir need not pre-exist and the source Makefile is used.
Applied to modules/libs/depend pattern rules and the
tcllibrary/mains/techs/install/clean loops.
* database/database.h: generate from ${MAGICSRC}/.../database.h.in into
the build tree (mkdir -p database), via the generated build-tree
${MAGICDIR}/scripts/makedbh.
* install-dirs/install-tcl-dirs use ${SCRIPTS}/mkdirs (now source-tree);
clean skips absent build subdirs; distclean/dist/tags updated for the
split source/build layout.
scripts/defs.mak.in:
* SCRIPTS now points at the source tree (${MAGICSRC}/scripts) for the
static helpers (mkdirs, printmans, ...); the one generated helper,
makedbh, is referenced directly at ${MAGICDIR}/scripts (build tree).
* Guard VPATH so it is set only inside module subdirectories, never at
the build top -- a top-level VPATH into the source tree could let a
stale source database/database.h shadow the build-tree copy.
scripts/configure.in: AC_CONFIG_FILES([Makefile:Makefile.in]); regenerated
scripts/configure.
Verified out-of-tree: `../configure && make modules && make libs` builds
all 33 module libraries (lib*.o and lib*.a) plus the generated
database/database.h into the build tree, with no errors and the source
tree left clean. A full `make` (link the magic program, build techs)
still needs the later outlier fixes (magic/, scmos/, ...).

With the autoconf layer relocatable, teach the shared make
files to read sources from the source tree and write objects into the
build tree. The ~26 "standard" and "near-standard" module Makefiles now
build out-of-tree with no per-module edits.
scripts/defs.mak.in:
* Add MAGICSRC = @abs_top_srcdir@ (absolute source top) and derive each
module's srcdir/VPATH from CURDIR relative to the build top:
BUILD_TOP := $(abspath $(MAGICDIR))
MODULE_SUBPATH := $(subst $(BUILD_TOP),,$(CURDIR))
srcdir := $(MAGICSRC)$(MODULE_SUBPATH)
VPATH := $(srcdir)
(MAGICDIR keeps meaning the *build* top; in-tree the trees coincide.)
* CPPFLAGS: add -I${MAGICSRC} (source top, for "<module>/<hdr>.h") and
-I${srcdir} (same-dir headers), keeping -I${MAGICDIR} for the generated
database/database.h in the build top.
* MAGIC_VERSION/REVISION read ${MAGICSRC}/VERSION; MAGIC_COMMIT uses
`git -C ${MAGICSRC}` so it works from a build dir outside the work-tree.
rules.mak:
* Compile rule: `-c $*.c` -> `-c $< -o $@` so the source is found via
VPATH in srcdir and the object is written to the build cwd.
* Depend and tags rules: prefix sources with $(srcdir)/ (they are passed
to the compiler/ctags directly, which do not honor VPATH).
scripts/configure.in: AC_CONFIG_FILES([rules.mak:rules.mak]) copies the
VPATH-aware rules.mak into the build top, so a single ${MAGICDIR}
resolves both `include`s in every subdir Makefile. Regenerated configure.
Known limitation (v1): the Depend post-processing sed strips
absolute-path headers, so with an absolute srcdir most header deps are
dropped; out-of-tree incremental header-change rebuilds are weaker.
Depend is already "optimistic/optional"; relativizing is a follow-up.
Verified out-of-tree: `tiles` and `drc` (the latter #includes the
generated database/database.h) build to completion; all objects land in
the build tree; the source tree stays clean.

Enable `mkdir build; cd build; ../configure` to run entirely in the build
directory, with generated config landing there instead of in the source
tree. This is the autoconf-layer groundwork for a full VPATH build; the
make layer (defs.mak/rules.mak VPATH support, per-dir orchestration) is
still to come, so an out-of-tree `make` is not yet expected to work.
Changes:
* configure (wrapper): run the generated config.status in the *current*
directory with --srcdir pointing back at the source tree (instead of
`cd scripts`), so outputs land in the build dir. Uses an absolute
basedir so any build-dir location works, not just a subdir of srcdir.
* scripts/configure.in:
- AC_CONFIG_AUX_DIR(.) -> AC_CONFIG_AUX_DIR(scripts). Once srcdir
resolves to the true top (scripts' parent, where rules.mak lives),
autoconf searches for install-sh/config.sub/... relative to srcdir;
"." pointed at the wrong place and out-of-tree configure died with
"cannot find install-sh".
- Name the .in templates explicitly
(defs.mak:scripts/defs.mak.in, scripts/makedbh:scripts/makedbh.in)
so config.status finds them from a separate build dir. defs.mak is
written to the build top; makedbh under build/scripts/ to match
${SCRIPTS}/makedbh.
- Drop the trailing `cp defs.mak ..`; defs.mak is now generated in the
build top directly, and from a build dir the copy would clobber the
source tree's defs.mak.
* scripts/configure: regenerated with autoconf 2.69.
Verified: out-of-tree `../configure` completes rc=0, writes defs.mak /
scripts/makedbh / config.status into the build dir, records
srcdir=<source top>, and leaves the source tree's tracked files and
generated defs.mak/makedbh untouched.

Also fixed up CC/CXX/CXXFLAGS in the same way.
Main notable concern the tclmagic.so now has reordered position of
$LDFLAGS (was start AND end of list, now start of list only),
$LDDL_FLAGS would have already provided it start of list, so it
would be duplicated set of options.
@LDDL_FLAGS@ no longer prepend $LDFLAGS which is now explicit in the
Makefile to allow specific target control.
The purpose of all this is the toplevel ./configure now has LDFLAGS
control passed down to linker command lines as configure --help
indicates.
Bump VERSION to 8.3.645.
magic.wasm can now be built as two variants packaged in the same npm
release: notcl/ (legacy, magic's own parser) and tcl/ (intubun/tcl 9.x
statically linked, commands evaluated by Tcl_EvalEx). The TCL fork is
pinned via npm/tcl.ref and cloned/built by magic itself — the tcl/
checkout is treated as read-only and built out-of-source into
magic/build-tcl-wasm/.
Configure layer:
- New usingTk variable decoupled from usingTcl in scripts/configure.in
+ scripts/configure, so --with-tcl --without-tk is finally a valid
combination. Native Linux Tcl+Tk builds keep their previous behaviour
(both flags default to enabled).
- When usingTk is empty, configure passes -DMAGIC_NO_TK so the small
number of remaining Tk callsites in tcltk/tclmagic.{h,c} compile out,
and TKCOMMON_SRCS / USE_TK_STUBS are omitted from the link.
WASM build orchestration:
- toolchains/emscripten/build-tcl-wasm.sh builds libtcl9.x.a + libtclstub.a
+ tclConfig.sh out-of-source from a pristine intubun/tcl checkout.
- npm/build.sh grew a --variant=<tcl|notcl|both> flag and writes its
outputs into npm/tcl/ and npm/notcl/. It also clones intubun/tcl with
autocrlf=false at the SHA pinned by npm/tcl.ref.
- magic/Makefile (WASM block only): magicWasm.o is now compiled with
DFLAGS_NOSTUB so Tcl_CreateInterp resolves to libtcl9.x directly
before tclStubsPtr is set. magic.js link pulls in LIB_SPECS_NOSTUB
and -ltclstub. After rules.mak include, magic: is a phony alias for
magic.js so the generic ${MODULE} recipe doesn't fight it.
- toolchains/emscripten/defs.mak: add -sUSE_ZLIB=1 (libtcl9 references
zlib), replace -sSTACK_SIZE=N with -Wl,-z,stack-size=N (emcc >=5
rejects the setting form).
- magic/magicWasm.c bootstraps the embedded interp under MAGIC_WRAPPER
(Tcl_CreateInterp -> Tcl_Init -> Tclmagic_Init) and routes
run_command through Tcl_EvalEx.
- magic/magicTop.c: gate MagicVersion/Revision/CompileTime on
!MAGIC_WRAPPER so they don't collide with the copies in
tcltk/tclmagic.c when both objects land in the same wasm binary.
npm package:
- Subpath exports: ".", "./tcl", "./notcl". Default import keeps the
pre-existing non-TCL behaviour for backward compatibility.
- examples/smoke-tcl.mjs exercises the TCL variant.
CI:
- main-wasm.yml clones intubun/tcl at the pinned ref, builds both
variants via npm/build.sh --variant=both, runs the existing notcl
test suite and the new TCL smoke test, and publishes only on a
v<x.y.z>... git tag. Tag name (minus the leading v) becomes the
npm version.
./configure

sed -e 's/^#FEATURE_FLAGS /FEATURE_FLAGS /' -i defs.mak
make
make install
This is a standard autoconf variable, it was probably disabled due to
how the graphics/Makefile works and the more complex detection taking
place there.
Needed to use it to add -lpthread to some platforms (freebsd/openbsd)
to make it build out the box.
