Problems building QtGStreamer release build on Windows

Fri Dec 14 03:33:11 PST 2012

Thanks, Andoni.

I tried adding the property sheet to the INSTALL project in VS 2010, and 
recompiled. Now I get lots of compiler errors instead:

21>c:\Program Files (x86)\Microsoft Visual Studio 
10.0\VC\include\iosfwd(19): error C2146: syntax error : missing ';' 
before identifier 'streamoff'
21>c:\Program Files (x86)\Microsoft Visual Studio

Etc etc etc. Any idea what's going wrong this time?

Chris, are you able to run the example applications in release mode now?

Best regards,
Ola
