Just a footnote to the thread on makefiles. I installed mingw and msys on vista to see if the cross-compile would produce a working windows executable from the same linux source I have been working with. It did without a hitch. The External library install (gsl) is quite simple. You simply add the includes, shared libs, aclocal info into the existing mingw environment in their usual places and then just build as you would on Linux. The only difference is your executable now has a .exe appended to it :p 21:31 alchemy:~/test> make -f Makefile.sim gcc -O2 -Wall -W -Wno-unused -c -o sim_orbm.o sim_orbm.c gcc -O2 -Wall -W -Wno-unused -c -o fn_const.o fn_const.c gcc -O2 -Wall -W -Wno-unused -c -o fn_state.o fn_state.c gcc -O2 -Wall -W -Wno-unused -c -o isolv_state.o isolv_state.c gcc -o orbs sim_orbm.o fn_const.o fn_state.o isolv_state.o -Wl -lgslcblas -lgsl -lm Info: resolving _gsl_root_fsolver_brent by linking to __imp__gsl_root_fsolver_brent (auto-import) c:/mingw/bin/../lib/gcc/mingw32/4.5.0/../../../../mingw32/bin/ld.exe: warning: auto-importing has been activated without --enable-auto-import specified on the command line.

I installed with mingw-get instead of from the 11.3 mingw repo, but no reason the rpms shouldn't work the same. -- David C. Rankin, J.D., P.E.
