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 ?

JKSH

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
