Dear all, Does anyone know how to create .a files for use with packages? I have the following situation: A directory 'PACK' with a number of ghc-generated object (.o) files. When I do the following: $ ghc Test.o PACK/*.o -o Test everything works fine. However, when I say: $ cd PACK $ ar -rvs libPack.a *.o $ cd .. And then do the following: $ ghc Test.o -LPACK -lPack -o Test GHC starts complaining about "warning: type and size of dynamic symbol `<ModuleName>_<FunctionName>_closure' are not defined". These are precisely the functions that the module Test is using. The above generates an executable, but results in a segmentation fault. Naturally, libPack.a cannot be used for a package either. (Getting the same results.) What am I doing wrong? I am doing all this with ghc5.04 on SunOS4. Thanks, /Koen. -- Koen Claessen http://www.cs.chalmers.se/~koen Chalmers University, Gothenburg, Sweden.
