Hello (and sorry for my English),
I downloaded the VideoCapture module on the http://videocapture.sourceforge.net/ site. I tested it with a webcam and that functions. Now I want to compile his file .cpp (vidcap.cpp). Thereafter, the idea is to be able to modify the code to include my own modifications. For the moment I only try to compile, but does not arrive :( I will try to pose my problem : First of all I am under Windows xp because I must use DirectX. I use the MinGW compiler. I use following script (setup.py) to be able to compile : nomModule = 'vidcap' from distutils.core import setup, Extension setup(name = nomModule, ext_modules = [ Extension(nomModule, sources = [ nomModule+'.cpp'],\ include_dirs=["C:\DX90SDK\Include","C:\DX90SDK\Samples\C++\DirectShow\BaseClasses"],\ library_dirs=["C:\Python23\libs","C:\DX90SDK\Lib","C:\Python23\Enthought\MingW\lib"]) ]) The include_dirs enable me to indicate the access path has my .h that I need. And library_dirs in theory the libraries which I need (I say in theory because I do not have the impression that it takes into account, but we will return later). I try so the first compilation with : python setup.py build I have a few errors I try to resolve them Here the modifications which I have of bringing : In strmif.h: line 6164 : replace #ifndef _WINGDI_ by #ifndef _WINGDI_H line 20557 : Add EXTERN_GUID definition just before first EXTERN_GUID(): #ifndef EXTERN_GUID #define EXTERN_GUID(g,l1,s1,s2,c1,c2,c3,c4,c5,c6,c7,c8) DEFINE_GUID(g,l1,s1,s2,c1,c2,c3,c4,c5,c6,c7,c8) #endif line 28736 : Fix the tagVMRGUID struct (GUID -> ::GUID) ::GUID *pGUID; ::GUID GUID; Put UrlMon.h in the file include of DX90SDK (recover it in Microsoft Platform SDK) in the same way for MsXml.h. Then to define uCLSSPEC and QUERYCONTEXT, I have includes their definition directly in my file .cpp : //-------------------------------------------------------------------------------------- // definitions recuperées de c:\Program Files\Microsoft Plateform SDK\include\WTypes.h typedef struct tagCSPLATFORM { DWORD dwPlatformId; DWORD dwVersionHi; DWORD dwVersionLo; DWORD dwProcessorArch; } CSPLATFORM; #ifndef _LCID_DEFINED #define _LCID_DEFINED typedef DWORD LCID; #endif // !_LCID_DEFINED typedef struct tagQUERYCONTEXT { DWORD dwContext; CSPLATFORM Platform; LCID Locale; DWORD dwVersionHi; DWORD dwVersionLo; } QUERYCONTEXT; typedef WCHAR OLECHAR; typedef OLECHAR *LPOLESTR; typedef struct __MIDL___MIDL_itf_wtypes_0003_0001 { DWORD tyspec; union __MIDL___MIDL_itf_wtypes_0003_0005 { CLSID clsid; LPOLESTR pFileExt; LPOLESTR pMimeType; LPOLESTR pProgId; LPOLESTR pFileName; struct { LPOLESTR pPackageName; GUID PolicyId; } ByName; struct { GUID ObjectId; GUID PolicyId; } ByObjectId; } tagged_union; } uCLSSPEC; //-------------------------------------------------------------------------------------- Last thing modified in vidcap.cpp : line 774 : /*statichere*/ PyTypeObject Dev_Type = { Comment out statichere, because it was already declared in extern.

(#pragma warning( disable: 4049 ) /* more than 64k source lines */) Then my problem it is that it does not create my module .pyd. Maybe linker error ? But I don't see why that command 'cc' failed ! (I use gcc) I think the part C:\Python23\Enthought\MingW\bin\g in beginning line was disappeared ! I try to run all this command line, i.e. : C:\Python23\Enthought\MingW\bin\gcc -mno-cygwin -shared -s build\temp.win32-2.3\Release\vidcap.o build\temp.win32-2.3\Release\vidcap.def -LC:\Python23\libs -LC:\DX90SDK\Lib -LC:\Python23\Enthought\MingW\lib -Lc:\Python23\libs -Lc:\Python23\PCBuild -lpython23 -o build\lib.win32-2.3\vidcap.pyd Here a part of result : build\temp.win32-2.3\Release\vidcap.o(.text+0x570):vidcap.cpp: undefined reference to `IID_IGraphBuilder' build\temp.win32-2.3\Release\vidcap.o(.text+0x579):vidcap.cpp: undefined reference to `CLSID_FilterGraph' build\temp.win32-2.3\Release\vidcap.o(.text+0x57e):vidcap.cpp: undefined reference to [EMAIL PROTECTED]' build\temp.win32-2.3\Release\vidcap.o(.text+0x59e):vidcap.cpp: undefined reference to `IID_ICaptureGraphBuilder2' build\temp.win32-2.3\Release\vidcap.o(.text+0x5a7):vidcap.cpp: undefined reference to `CLSID_CaptureGraphBuilder2' build\temp.win32-2.3\Release\vidcap.o(.text+0x5ac):vidcap.cpp: undefined reference to [EMAIL PROTECTED]' ... I think it is a problem of linker error. However I show the right directory to recover libraries (-LC:\Python23\libs -LC:\DX90SDK\Lib -LC:\Python23\Enthought\MingW\lib), but apparently does not take into account. In short, how to make ? If I did not take the right method of resolution of my problem, how then I do to proceed ? Thanks for any ideas. Ps : I also wanted to compile it under dev-cpp to see. Result, same problem, but only 5 or 6 linker errors. I include in the parameters of linker : C:/Python23/libs/libpython23.a C:/DX90SDK/Lib/amstrmid.lib C:/Python23/Enthought/MingW/lib/libole32.a C:/Python23/Enthought/MingW/lib/liboleaut32.a Regards, Jérôme
