Does it link if you don't pass any parameters to ./configure? If it does then just throw the shared libraries away if you really don't want them.
If it doesn't and you want an immediate solution the source code for gmtime_r and strtok_r is available, just add it to your glpk compilation somewhere. The problem is that gmtime_r and strtok_r are optional POSIX features only required for systems using POSIX threads, which windows doesn't. You probably want to use winpthreads which may be as simple as adding -l pthread or not. If it isn't you may get a better answer from mingw help. ________________________________ From: Help-glpk <[email protected]> on behalf of [email protected] <[email protected]> Sent: 15 March 2018 13:35:31 To: [email protected] Subject: [Help-glpk] Compiling and linking problems 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 ../src/.libs/libglpk.a(libglpk_la-stdc.o): In function `glp_xgmtime': C:\Users\Mike\Documents\Projekte\CMPL-1-12\Cmpl\data\glpk-4.65\src/env/stdc.c:81: undefined reference to `gmtime_r' ../src/.libs/libglpk.a(libglpk_la-stdc.o): In function `glp_xstrtok': C:\Users\Mike\Documents\Projekte\CMPL-1-12\Cmpl\data\glpk-4.65\src/env/stdc.c:93: undefined reference to `strtok_r' collect2.exe: error: ld returned 1 exit status make[2]: *** [glpsol.exe] Error 1 make[2]: Leaving directory `/Documents/Projekte/CMPL-1-12/Cmpl/data/glpk-4.65/examples' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/Documents/Projekte/CMPL-1-12/Cmpl/data/glpk-4.65' make: *** [all] Error 2 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.
