Hi, the scripts are made for Ubuntu - I don't test for other Linux distributions. And I use both Qt3 and Qt4, so I need to call the 'qmake-qt4'.

build.sh should be run from the directory it is located in. Don't know why you can't create the directory - perhaps a permission thing?

I'm not sure about the segfault - I just got another error report on it.

Could you try setting line 418 in EngineWidget.cpp to
"glViewport(0,0,600,400)" and check if it still crashes? And if this
doesn't help, try putting in a 'return;' statement in line 410 to skip this
function?
