OS/2 tricks: Qt Creator and Perforce
If you are developing with Qt 4 on OS/2, Qt Creator is your best tool. By the way, Right after Qt Creator is started, a system is frozen during about 30 seconds. Unfortuantely, I could not find the cause of this. So just waited for a system to be unfrozen. Meanwhlie, some messages related to Perforce(p4) are being printed on a message window. I'm using p4 to access 4os2 repository. Hoping to fix this problem, I removed it from Qt Creator settings([Tools] - [Options] - [Version Control] - [Perfoce] - [Configuration] - [P4 command]). By this, the problem was fixed really. If you are using Perfoce(p4) and Qt Creator cause a system to be frozen, remove the settings for P4 from Qt Creator.
