Dear GHC users, I have the following problem and I wonder if anyone can help.
I am using the FFI to talk to a library of functions written in C++. On Unixes (Solaris, Linux) this works just fine if one adds the right -ldstdc++ here and there. However, I am using Cygwin now and that is where all the problems start. The C++ stuff compiles fine (using Cygwin's g++). The Haskell stuff compiles just fine (using Win Ghc). However, at linking time I get the following error: - undefined reference to '_impure_ptr' - undefined reference to 'operator delete(void*)' - undefined reference to 'vtable for ___cxxabiv1::__blahblah' These are all things that C++ uses internally. I think the problem is that I used Cygwin's g++ compiler and that Ghc uses Mingwin's gcc compiler to compile and link. However, I have tried to recompile the C++ libraries using the Mingwin C++ compiler but it starts throwing pages of error messages at me. The other way around: using a Cygwin specific GHC, seems more appropriate, but where does one get one of those? (I have never managed to compile one myself.) Any ideas? /Koen. _______________________________________________ Glasgow-haskell-users mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
