I am a Haskell enthusiast and am stuck in compiling my little Haskell program on Windows. My program uses the iconv package, which in turn uses an external library written in c / C ++. To do the job, I:
- Launch GNU-Iconv and add the bin folder, where libiconv-2.dll and libiconv2.dll are located before the
PATH variable. - Extracted and copied LibIconv developers files to the "mingw" folder Haskell platform location.
- Then 'cabal install iconv' compiles and I have the cabal package installed.
Now, when I try to create my module in Leksah, I get the following message from the GHC:
Building norms-parser-0.0.1... Linking dist\build\norms-parser\norms-parser.exe ... C:\Documents and Settings\kdv\Application Data\cabal\iconv-0.4.1.0\ghc-7.0.4/libHSiconv-0.4.1.0.a(hsiconv.o):hsiconv.c:(.text+0x7): undefined reference to `_imp__libiconv_open' C:\Documents and Settings\kdv\Application Data\cabal\iconv-0.4.1.0\ghc-7.0.4/libHSiconv-0.4.1.0.a(hsiconv.o):hsiconv.c:(.text+0x17): undefined reference to `_imp__libiconv' C:\Documents and Settings\kdv\Application Data\cabal\iconv-0.4.1.0\ghc-7.0.4/libHSiconv-0.4.1.0.a(hsiconv.o):hsiconv.c:(.text+0x27): undefined reference to `_imp__libiconv_close' collect2: ld returned 1 exit status
With "GHCi" I also run into a problem:
ghc.exe: unable to load package `iconv-0.4.1.0' ghc.exe: C:\Documents and Settings\kdv\Application Data\cabal\iconv-0.4.1.0\ghc- 7.0.4\HSiconv-0.4.1.0.o: unknown symbol `__imp__libiconv_open'
I think the likely solution is to properly configure the c / C ++ header files in the "mingw" folder and set the PATH variables to the "lib" files, but I know little about it, so any help would be greatly appreciated.
