Use autoconf in the source-code FMUs
By using autoconf, we move a lot of the work from the user of the
Makefiles to autoconf itself.
To try it out, cross-compiling for multiple platforms (with the FMU
unzipped to M.fmutmp):
(for arch in x86_64-w64-mingw32 x86_64-linux-gnu arm-linux-gnueabihf \
i686-linux-gnu i686-w64-mingw32
do
(cd M.fmutmp/sources/ && \
./configure --host=$arch CFLAGS=-Os && \
make -j6) || exit 1;
done)
So it is enough to pass the host and optionally CFLAGS (on Ubuntu).
Recommended packages on an x86_64 host:
apt-get install gcc-arm-linux-gnueabihf libc6-dev:i386 gcc-mingw-w64
Note that installing gcc-multilib conflicts with gcc-arm, which means
you need the i386 libc6 headers.- Loading branch information
