Greetings I am trying to import some functions from a windows DLL. I am getting strange errors. (This used to work with previous versions of GHC. 6.6 I think.). This is my import statement: foreign import stdcall "ace.h AdsConnect" adsConnect' :: CString -> Ptr CInt -> IO CInt This is the build output. C:\moonar>\bin\make.exe ghc --make -ffi main.hs -ffi adsapi.hs -optc -DWIN32 native.cpp -lace32 -L/hom e/pjdurai/dev/moonar -L/tmp/Advantage -o moonar.exe [1 of 2] Compiling AdsApi ( adsapi.hs, adsapi.o ) [2 of 2] Compiling Main ( main.hs, main.o ) Linking moonar.exe ... adsapi.o(.text+0x124):fake: undefined reference to `AdsConnect@8' adsapi.o(.text+0x260):fake: undefined reference to `AdsDisconnect@4' collect2: ld returned 1 exit status make: *** [main.exe] Error 1 It actually links without errors if I use 'ccall' instead of 'stdcall'. But the executable segfaults when the function is called. I had the same code working with 'stdcall' declaration a while ago. (With GCH 6.6 I think) I am using ghc-6.8.3 on Windows XP SP2. appreciate your time. thanks pj
