Dear Mike,

Can you share a copy of the generated config.h?

Best Regards,

Dear GLPK-Team,

 

I have got some problems with building glpk 4.65 on Windows 10 with msys/mingw.

 

I tried to build it with:

./configure --enable-static --disable-shared

make

 

Configure finished without problems. All sources are compiled without errors.

But it ends with the following issues:

…

/bin/sh ../libtool --tag=CC   --mode=link gcc  -g -O2   -o glpsol.exe glpsol.o ../src/libglpk.la -lm

libtool: link: gcc -g -O2 -o glpsol.exe glpsol.o  ../src/.libs/libglpk.a

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/Documents/Projekte/CMPL-1-12/Cmpl/data/glpk-4.65'

I have seen that in stdc.c are alternative versions of some function depending on some defines. But I am not sure what is  do do. I was wondering that the defines are  set by the configure script.    

I use as mentioned before msys/mingw:

$ gcc -v

Using built-in specs.

COLLECT_GCC=C:\MinGW\bin\gcc.exe

COLLECT_LTO_WRAPPER=c:/mingw/bin/../libexec/gcc/mingw32/6.3.0/lto-wrapper.exe

Target: mingw32

Configured with: ../src/gcc-6.3.0/configure --build=x86_64-pc-linux-gnu --host=mingw32 --target=mingw32 --with-gmp=/mingw --with-mpfr --with-mpc=/mingw --with-isl=/mingw --prefix=/mingw --disable-win32-registry --with-arch=i586 --with-tune=generic --enable-languages=c,c++,objc,obj-c++,fortran,ada --with-pkgversion='MinGW.org GCC-6.3.0-1' --enable-static --enable-shared --enable-threads --with-dwarf2 --disable-sjlj-exceptions --enable-version-specific-runtime-libs --with-libiconv-prefix=/mingw --with-libintl-prefix=/mingw --enable-libstdcxx-debug --enable-libgomp --disable-libvtv --enable-nls

Thread model: win32

gcc version 6.3.0 (MinGW.org GCC-6.3.0-1)

 

 

Any suggestions are welcome!

 

Thanks,

 

Mike
