With a pattern rule, the recipe will only be executed once, even when
the rule has multiple targets. Using this to handle the output from
bison is included as an example in the GNU make manual.
This fixes the makefiles so that bison-generated header files will be
regenerated if they are deleted.
bison 3.4.1 writes the header file before the c++ file. Our makefile
rules make the header files depend on the c++ files, so we need to
fix the timestamps accordingly.
(cherry picked from commit 5bb6c7f53a)
When a black-box item requests a specific footprint, we need to
read a file (<footprint>.fp) that contains the actual details
about that footprint. Support parse of that file and use the
loaded Element to generate the footprint for the item.
On some systems having both %.o: %.c and %.o: %.cc rules confused the
make system. This is directory only has C++ code so remove the %o: %.c
rule. Also the C++ compiler should be used to link C++ object code.
On Ubunto 10.10 (32 bit) tgt-pcb would not build because there were
include file issues. This patch fixes those and uses the C++ include
version where appropriate.
The main .pcb file contains elements, and basic PCB status.
Write out a .pcb file with stub Elements for each of the devices
in the design.
Rearrange the way the files are reported to the code generator
so that we can sensibly express where the output files are.
