what gcc qt4.8.1 uses ??

[jesse_mark]

does the qt uses the gcc version in the system, or its has its own version ??

also how can i know which OpenMp API the qt4.8.1 uses ?? is it installed with it ?? i Use qt creator 2.4.1.
or
how can i know what version of OpenMP it uses, i insert some OpenMP pragma and it compiles and runs fine.
I just want to know what version it is and how can i make qt points to other version.

I would appreciated any inlighting in these matters. or place to look into.

Thank you

Qt uses whatever is in the PATH or whatever is set in Qt Creator.

The Qt library does not use or include OpenMP.

Your project can include and use OpenMP. It's up to you to tell your project how to find and link the library and its associated files.
See Declaring Other Libraries in the QMake manual, or the equivalent in the manual of any other build system you are using.
