Hi all, I'm trying to compile QtGstreamer using VS2008. I already managed to compile Gstreamer, and have everything else is properly installed (ossbuild, qt, boost, byson/flexm automoc, cmake). I've made a few tests with gst-launch and also succeeded writing a "Hello World" Gstreamer to play audio/videos and everything seems fine. I'm following the instructions from <a href="http://gstreamer.freedesktop.org/wiki/QtGStreamer/BuildingOnWindows">http://gstreamer.freedesktop.org/wiki/QtGStreamer/BuildingOnWindows</a> Looking at the instructions at section "Building QtGStreamer", after setting the PATH cmake is being configured with: cmake -G "Visual Studio 9 2008" -DCMAKE_INSTALL_PREFIX="C:\qt-gstreamer\install" ^ -DBOOST_ROOT="C:\boost_1_45_0" -DCMAKE_INCLUDE_PATH="C:\ossbuild\Shared\MSVC\Include;C:\ossbuild\Shared\Build\Windows\Win32\include\libxml2" ^ -DCMAKE_PREFIX_PATH="C:\ossbuild\Build\Windows\Win32\Release;C:\ossbuild\Shared\Build\Windows\Win32;C:\automoc\install" ..

Anyway, if you notice the variable CMAKE_INCLUDE_PATH you'll see that the include path for libxml2 is also being added. That's because I'm trying to fix the errors which are all related to: 9>C:\ossbuild\Build\Windows\Win32\Release\include\gstreamer-0.10\gst/gstconfig.h(131) : fatal error C1083: Cannot open include file: 'libxml/parser.h': No such file or directory Now, I know for sure the path "C:\ossbuild\Shared\Build\Windows\Win32\include\libxml2\libxml\parser.h" is valid. I'm not sure how to fix this problem. Hopefully someone can shed a light on this. Thanks, -- Karl Phillip
