Hello Mike, https://stackoverflow.com/questions/6394512/standard-c-library-in-mingw writes: "MinGW is designed to build native Windows code, and as such it builds against Windows' native libc."
So probably you want to change this line in src/env/stdc.c: -#elif defined(__WOE__) +#elif defined(__CYGWIN__) || defined(__MINGW32__) || defined(__WOE__) Please, reply if this works. Then Andrew could update it in the next version of GLPK. There might be more lines needing such a change: examples/glpsol.c:956:#ifndef __WOE__ src/env/time.c:88:#elif defined(__WOE__) src/env/dlsup.c:107:#elif defined(__WOE__) src/env/tls.c:85:#ifdef __WOE__ src/env/stdc.c:52:#elif defined(__WOE__) Best regards Heinrich On 03/15/2018 02:35 PM, mike.stegl...@berlin.de wrote: > 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.
