Going back to Qt 4

[gmodcake]

Hi,

All my question is in the topic, how do we go back to the old qt ? Qt4 ?

Thanks

Hi,

The first step is probably to download the Qt 4.8 libraries from http://qt-project.org/downloads

Done, I just passed 3h to figure out how to install it, no success, I was getting this error :undefined reference to `_Unwind_Resume'

Any tutorial or something ?

You'll have to give us more information.

• What platform are you on?
• Which package did you download?
• What steps did you take when you tried to install it?

I'm on windows;
I've downloaded this one : Qt libraries 4.8.4 for Windows (minGW 4.4, 317 MB)
Installing it ... I don't really know, I've tried so much things, but I mainly just added a kit in Tools->options->compiler and in my project I set the new kit to compile, and I got this error

Do you have MinGW 4.4 installed? Qt 4.8 officially supports GCC 4.4. I heard that GCC 4.5 and 4.6 work too, but not GCC 4.7

After you have MinGW, you need to:

Make sure that your compiler is set in Tools -> Options -> Build & Run -> Compiler

Make sure that Qt 4.8 is set in Tools -> Options -> Build & Run -> Qt Versions

Make a new Kit that uses your compiler with Qt 4.8 in Tools -> Options -> Build & Run -> Kits

When you set up your project, make sure you choose the Kit you made in #3

I've installed it with MinGW 4.7 ... Where do I get MinGW 4.4 ? For the rest, I already did those step
