I am using QT-4.5.3 on a 64bit Fedora 14 HP server.

When I compile my applications I get a massive amount of "-pthread" appearing during the linking stage. The following is an example:

"g++ -m64 -Wl,-rpath,/usr/local/qt-4.5.3/lib -o ctbfee .obj/main.o .obj/logger.o .obj/statuspane.o .obj/mainwindow.o .obj/moc_statuspane.o .obj/moc_mainwindow.o -L/usr/local/qt-4.5.3/lib -lQt3Support -L/usr/local/qt-4.5.3/lib -lQtSql -pthread -pthread -pthread -pthread -lQtXml -pthread -pthread -pthread -pthread -L/usr/X11R6/lib64 -pthread -pthread -pthread -pthread -pthread -pthread -pthread -pthread -pthread -pthread -pthread -pthread -pthread -pthread -lQtGui -pthread -lpng -lfreetype -pthread -lgobject-2.0 -lSM -lICE -pthread -pthread -lXrender -lfontconfig -lXext -lX11 -lQtNetwork -pthread -pthread -lQtCore -lz -lm -pthread -lgthread-2.0 -lrt -lglib-2.0 -ldl -lpthread"

Is this a problem? If so, how can it be fixed.

The reason I am worried about this is because I am getting invalid results (NaN's) from a call to a library function that I installed (BLAS). I was wondering if maybe these copies links of pthread were somehow corrupting the BLAS static libs. (Far fetched, I know, but the BLAS library looks good, and I am running out of ideas
