Hello, i have one Problem with ghc (and FFI). I wrote some functions in C and compiled that file. After that I typed: ghci -fffi komplett.obj test.lhs -l apr.lib and got the following error meassage: Loading package base ... linking ... done Warning: ignoring unrecognised input 'apr.lib' Loading object (static) kompett.obj ... done Loading object (dynamic) ... failed. Dynamic Linker error message was: addDLL: unknown error Whilst trying to load (dynamic) Directories to search are: C:\ghc\ghc-6.2.1\bin ghc.exe: user specified .o/.so/.DLL could not be loaded I have to use different Libraries from Subversion (subversion.tigris.org => http://subversion.tigris.org/files/documents/15/14892/svn-win32-1.0.6_de v.zip).
