Hi, Is this the right place for GHC API queries? If not, is there anywhere better? I want to compile a Haskell module, much like `ghc --make` or `ghc -c` does. The sample code on the Haskell wiki (https://wiki.haskell.org/GHC/As_a_library#A_Simple_Example), StackOverflow (http://stackoverflow.com/a/5631338/160673) and in GHC API slides (http://sneezy.cs.nott.ac.uk/fplunch/weblog/wp-content/uploads/2008/12/ghc-ap...) says: import GHC import GHC.Paths ( libdir ) import DynFlags main = defaultErrorHandler defaultFatalMessager defaultFlushOut $ do runGhc (Just libdir) $ do dflags <- getSessionDynFlags setSessionDynFlags dflags target <- guessTarget "Test.hs" Nothing setTargets [target] load LoadAllTargets However, given a `Test.hs` file with the contents `main = print 1`, I get the error: C:/Program Files (x86)/MinGHC-7.8.3/ghc-7.8.3/mingw/bin/ld.exe: cannot find -lHSbase-4.7.0.1-ghc7.8.3 C:/Program Files (x86)/MinGHC-7.8.3/ghc-7.8.3/mingw/bin/ld.exe: cannot find -lHSinteger-gmp-0.5.1.0-ghc7.8.3 C:/Program Files (x86)/MinGHC-7.8.3/ghc-7.8.3/mingw/bin/ld.exe: cannot find -lHSghc-prim-0.3.1.0-ghc7.8.3 C:/Program Files (x86)/MinGHC-7.8.3/ghc-7.8.3/mingw/bin/ld.exe: cannot find -lHSrts-ghc7.8.3 C:/Program Files (x86)/MinGHC-7.8.3/ghc-7.8.3/mingw/bin/ld.exe: cannot find -lffi-6 collect2: ld returned 1 exit status Has the recipe changed? By turning up the verbosity, I was able to compare the command line passed to the linker. The failing GHC API call contains: "-lHSbase-4.7.0.1-ghc7.8.3" "-lHSinteger-gmp-0.5.1.0-ghc7.8.3" "-lHSghc-prim-0.3.1.0-ghc7.8.3" "-lHSrts-ghc7.8.3" "-lffi-6" While the succeeding ghc --make contains: "-lHSbase-4.7.0.1" "-lHSinteger-gmp-0.5.1.0" "-lHSghc-prim-0.3.1.0" "-lHSrts" "-lCffi-6" Should I be getting DynFlags differently to influence those link variables? Thanks, Neil
