I think I found the problem. On Windows, "cmake --build . --target install" is not copying "C:\qt-gstreamer\src\QGst\Utils\global.h" to the installation dir "C:\qt-gstreamer\install\include\QtGStreamer\QGst\Utils" as it does on Linux. Maybe George can release a proper fix to this issue soon. Meanwhile, just copy global.h to the right place. -- Karl Phillip <div class="gmail_quote">On Mon, Dec 19, 2011 at 3:16 PM, Karl Phillip <<a href="mailto:maxphil@gmail.com">maxphil@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I have successfully compiled QtGstreamer on Windows using VS2008, and examples/player works fine after the patch suggested by George in <a href="http://lists.freedesktop.org/archives/gstreamer-devel/2011-December/034351.html" target="_blank">http://lists.freedesktop.org/archives/gstreamer-devel/2011-December/034351.html</a> Now I'm having problems writting a minimal application that has "#include <QGst/Utils/ApplicationSink>" because it causes the compilation to fail with the following error: c:\qt-gstreamer\install\include\qtgstreamer\qgst\utils\applicationsink.h(21) : fatal error C1083: Cannot open include file: 'global.h': No such file or directory Looking at applicationsink.h reveals that it is including global.h as a local file: #ifndef QGST_UTILS_APPLICATIONSINK_H #define QGST_UTILS_APPLICATIONSINK_H #include "global.h" // <------ error #include "../element.h" #include "../bufferlist.h" The problem seems to be that there's NO global.h at the same directory as applicationsink.h.
