[gecode-users] Linker errors when compiling Gecode with GCC on Windows

[Guido Tack]

Hi,

please try linking in the order explained in Sect. 2.3.3 in MPG.  If that doesn't solve the problem, try the --disable-gcc-visibility configure option (although I'm not sure if that works with mingw).  It's possible that the visibility attributes don't work with the current configuration for mingw (we don't test mingw at all).

Cheers,
Guido
