Dear all, I am able to build glpk v4.65 with --disable-reentrant. Unfortunately, Heinrich’s solution does not work for me. Thank you for all suggestions, Mike Von: Chris Matrakidis <address@hidden>

Betreff: Re: [Help-glpk] Compiling and linking problems Dear Mike, The config.h you provided looks correct. Until we find a more permanent solution, you have two options: a) run configure with --disable-reentrant, or b) follow Heinrich's solution This has been discussed in the past[1] and Andrew seems to favour option a.

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
