Thanks, this is a start. I'd installed both the WinBuild and WinBuild-dev  0.10.5 packages after installing (un-zipping) the msys download.

I added the PKG_CONFIG_PATH and now my MINGW32 window  env command shows:

    GST_PLUGIN_PATH=c:\gstreamer\lib\gstreamer-0.10
    PKG_CONFIG_PATH=c:\gstreamer\lib\pkgconfig\
    MAKE_MODE=unix

but now the build command gives:
$ gcc HelloGstreamer.c -o HelloGstreamer `pkg-config --cflags --libs gstreamer-0.10`

Obviously it did not.   I can test the install on my XP notebook but this is not really going to help since I don't have a video capture card for my notebook.

Frankly I wouldn't bet the farm on it working on XP either, as I copied the WS2_32.dll from my XP system to the gstreamer\bin directory and created an empty .local file, that got rid of one set of "Entry Point Not Found" errors but created another:

"The procedure entry point RtlIpv4StringToAddressW" not found in ntdll.dll

Grabbing the XP ntdll.dll and putting it in the gstreamer/bin directory didn't change anything.  Since I don't need to use any of the network related plugins, just getting past this might let me proceed.


Obviously if any of this about WinBuild not supporting Windows2000 was documented at  http://code.google.com/p/ossbuild/downloads/list I wouldn't have bothered downloading anything :(
