QT Creator 2.2.0 Ubuntu cannot run

Hi.

I'm done installing qt on ubuntu. Compiled and installed.
Now I install QT creator.
Done too.
But when I click to run qt creator. I got this error:
Failed to load core: [some long path]/Nokia/libCore.so: Cannot load library [some long path]/qtcreator-2.2.0/lib/qtcreator/plugins/Nokia/libCore.so: (/usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by [some long path]/qtcreator-2.2.0/lib/qtcreator/plugins/Nokia/../../libBotan.so.1))

What am I missing? I was able to compile and gmake the QT on Ubuntu. So I think all my libraries are installed and properly PATHed... Please help.

Thanks.

Apparently you compiled the application against a different version of the libstdc++ library than the one set as default on your system.

I dont quite get it.
I only compiled the qt on ubuntu. NOT the qt creator.
QT creator was downloaded from the qt website.
and I simply install the qt creator and double click on the
button to run. And it does not run but gave the above error.
Any pointers? Thanks.

Qt Creator uses Qt. And it uses libstdc++ which might be incompatible with what you have in your system.
