notably on debian gnu/linux with package `mingw-w64'
cross-compile a mingw 32bit windows executable with this incantation:
(compile "
./autogen.sh
rm -rf tmp-build tmp-output
mkdir -p tmp-build tmp-output
( cd tmp-build && ../configure \
--build=$(../config.guess) \
--host=i686-w64-mingw32 \
--prefix='c:/spice' \
--exec-prefix='c:/spice'\
--with-windows --enable-xspice --enable-cider --disable-debug )
LC_ALL=C make -C tmp-build -k -j6
LC_ALL=C make -C tmp-build -k -j6 DESTDIR=$(pwd)/tmp-output/ install
(cd 'tmp-output/c:/' && zip -r - .) > tmp-output.zip
")
compilation to Win64 works the same way, with
--host=x86_64-w64-mingw32
The tmp-output.zip directory structure resembles the
structure of our original sourceforge ngspice-26_140112.zip windows package
ready to be unzip'ed in c:/
Though the testfiles, examples and documentation is missing.
