Linker fails using qt-project built standalone with a strange error

[sanyibacsi]

Hello There,

I just hope someone can help me since this issue gets really miserable.

What I have done:

1. Downloaded "Qt 5.1.0 for Linux 64-bit (416 MB)" from http://qt-project.org/downloads
2. Installed to default path, including sources
3. Set PATH variable in .bash_profile so qmake is found
4. Created a tiny application what just opens a window using "webkitwidgets" and downloads a website.
5. Complied on Windows. Works fine there. Tried to compile on linux.
6. qmake was fine. Makefile is generated and looks okay.
7. Miserable errors are happening on make:

The O/S is CentOS 6.0 x64. Both mesa GL, GLU, devels are installed. Libraries are found in /usr/lib64.
I looked through the net searching for ideas. The only one I found was that gstreamer version might be wrong. So I tried:
Install gstreamer as:
[code]
sudo yum install gstreamer
Loaded plugins: fastestmirror, refresh-packagekit
Loading mirror speeds from cached hostfile

• base: ftp.freepark.org
• extras: ftp.freepark.org
• updates: ftp.freepark.org
  Setting up Install Process
  Package gstreamer-0.10.29-1.el6.x86_64 already installed and latest version
  Nothing to do
  [/code]

9. I could not find any clue on what gstreamer version the WebKit supplied witn Qt 5.1.0.

10. Please help me! What should I do to get my make done?

Thanks :)
