[gecode-users] Compiling Gecode under MinGW

[Maik Riechert]

Hi,

As I want to use Gecode in Windows with Haskell and cabal-install uses 
GCC, I need to rebuild it from source in MinGW/MSYS.

I did a ./configure --with-host-os=linux which went through and then 
"make" which had these errors:

g++ -I. -mthreads -ffast-math -fno-strict-aliasing -O3 
-fvisibility=hidden -ggdb -pipe -Wall -Wextra -pthread -DNDEBUG   \
         -c -o gecode/support/exception.o  gecode/support/exception.cpp
In file included from ./gecode/support/thread.hpp:264:0,
                  from ./gecode/support.hh:130,
                  from gecode/support/exception.cpp:38:

Gecode::Exception::what() const' redeclared without dllimport attribute:

Is it possible to make this compatible? Why is it failing at all?

Cheers
Maik
