Next: errors in building cmodview ================================== As to building the cmodview project I get errors under Windows XP (Qt-> 4.5.2, QtCreator 1.3.0) using cmodview.pro "Cannot open include file: 'QGLShaderProgram': No such file or directory and 17 errors under Linux (Qt-> 4.3.1, QtCreator 1.3.0) using cmodview.pro ------------------------------------------- Running build steps for project cmodview...

Error while building project cmodview When executing build step 'Make' ------------------------------------------- +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I don't think it is a good idea to use the QGLShaderProgram class (and include file) that was only introduced in Qt 4.6! E.g. in Linux distros the versions are usually somewhat behind... +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ That is also the reason why I get lots of errors, both with Qt 4.5.2 under Windows XP and with Qt 4.3.1 of my SuSE Linux installation.
