Also see these: qmake Tutorial, Atariage thread, AspeQt for OSX, Qt5 Platforms, QT5.2.1 downloads for all platforms, Qt for Mac OSX, How to install and getting started with Qt5 SDK on Mac OSX 10.9 Maverick


Note: I am neither a Linux nor an OS X expert, actually far from it. These compile instructions are tips that I collected from various Atariage threads, so your milage will vary and you are on your own with installing Qt5 and compiling AspeQt. If you have useful tips for your particular Linux/OS X distro please let me know so that I can include them in this file.

thanks and have fun
