Backwards compatibility question Qt and QtCreator

**spawn9997** · 27th January 2010, 21:25

Hello all,

Simple question really... Does anyone know of a compatibility issue between Qt 4.4.2 and Qt Creator 1.3.x and up?

The reason I ask is that I tried to upgrade my version of QtCreator and I could no longer debug my program; of course editing and compiling worked fine. It found everything o.k. but it could not compile the gdbmacros.cpp file. Kept giving an error that looked like it was coming from the Qt libs (very similar to something that happens when a lib has been updated and your code is using outdated or non-existent functions).
Since I have uninstalled 1.3, I don't have the error with me right now. If anyone has heard of this then let me know. If not I will reinstall it and show you what error I get and also my machine type and compiler.

I know I am running Suse Linux 10.3 which is 2.6 and 64 bit.

p.s.: I tried to use Qt4.5.2 and it was able to use the debug code but then again our code would need to be updated. (Not an option at this time).

thanks all,

Qt Creator 1.3 will not work with Qt 4.4 or 4.5. It requires 4.6.

You need Qt 4.6 to compile Qt Creator itself but should be able to use it with older versions to compile your own projects. If that does not work, bugreports.qt.nokia.com is the place to go.

ktk,

Yes I was able to use it; but could not get the debugger to work because debugger helper file(s) needs 4.6 to be rebuild. No worries. I'll use 1.2.1 until we move to 4.6 or higher. (probably as soon as this project is over).
