Hi, Here are some details on my building of HDirect with ghc-6.6, and where I am stuck. Skipping details about deprecated libs (such as IOExts) and some name conflicts (NativeInfo), I succeeded in building the "ihc.exe", the "hdirect" and "com" libs. I installed the "com" lib as a package on my system: $ ghc-pkg.exe list c:/ghc/ghc-6.6\package.conf: [...] com-0.22, fgl-5.2, (ghc-6.6), [...] $ ghc-pkg.exe describe com name: com version: 0.22 [...] exposed: True exposed-modules: AutoPrim Automation ClassFactory Com ComDll ComException ComPrim ComServ Connection ConnectionPoint EnumInterface ExeServer HDirect Pointer PointerPrim SafeArray StdDispatch StdTypes TypeLib WideString [...] extra-libraries: kernel32 user32 ole32 oleaut32 advapi32 From here, I tried to bootstrap the ihc compiler with the support for typelibs. $ cd ../src $ rm -f *.o $ make depend SUPPORT_TYPELIBS=YES $ make SUPPORT_TYPELIBS=YES But the "make depend" fails : $ make depend SUPPORT_TYPELIBS=YES ghc -M -optdep-f -optdep.depend -optdep-o -optdepo -cpp -DBEGIN_SUPPORT_TYPELIB S='-}' -DEND_SUPPORT_TYPELIBS='{-' -DBEGIN_NOT_SUPPORT_TYPELIBS='{-' -DEND_NOT_S UPPORT_TYPELIBS='-}' -package com -fglasgow-exts -static -fvia-C -Rghc-timing -Wall -package com AbsHUtils.lhs AbstractH.lhs Attribute.lhs Bag.lhs BasicT ypes.lhs CStubGen.lhs CgMonad.lhs CodeGen.lhs CoreIDL.lhs CoreUtils.lhs DefGen.l hs Desugar.lhs DsMonad.lhs Env.lhs FiniteMap.lhs GetOpt.lhs HugsCodeGen.lhs IDLS yn.lhs IDLToken.lhs IDLUtils.lhs ImportLib.lhs JavaProxy.lhs Lex.lhs LexM.lhs Li bUtils.lhs Literal.lhs Main.lhs MarshallAbstract.lhs MarshallAuto.lhs MarshallCo re.lhs MarshallDep.lhs MarshallEnum.lhs MarshallFun.lhs MarshallJNI.lhs Marshall JServ.lhs MarshallMethod.lhs MarshallMonad.lhs MarshallServ.lhs MarshallStruct.l hs MarshallType.lhs MarshallUnion.lhs MarshallUtils.lhs MkImport.lhs NameSupply. lhs NormaliseType.lhs Opts.lhs PP.lhs PpAbstractH.lhs PpCore.lhs PpIDLSyn.lhs Pr eProc.lhs Pretty.lhs Rename.lhs RnMonad.lhs Skeleton.lhs SrcLoc.lhs SymbolTable. lhs TLBWriter.lhs TypeInfo.lhs Utils.lhs Validate.lhs CustomAttributes.hs Parser .hs Version.hs OmgParser.hs NativeInfo.hs ImportLib.lhs:39:7: Could not find module `TypeLib': I do not understand why "TypeLib" is not found, as it is included in the "com" package. This may be a newbie's question, excuse me if it has been answered millions of time. Sincerely yours, Samuel PS : if I use the option in the src/Makefile, which consists in using "-i../comlib" and other flags instead of "-package com", the "make depend" works, but the following make fails as follows : ghc -fglasgow-exts -static -fvia-C -Rghc-timing -Wall -i../lib -L../lib -I../lib -i../comlib -lole32 -loleaut32 -ladvapi32 -c ../comlib/AutoPrim.hs -o ../comlib/AutoPrim.o -osuf o ../comlib/AutoPrim.hs:69:0: Invalid type signature Hope this helps. ___________________________________________________________________________ Découvrez une nouvelle façon d'obtenir des réponses à toutes vos questions !
