Linking error in compiling application in Qt-Embedded-4.4.1 in mipsel architecture

Hi,

I am using Qt-embedded linux 4.4.1 in mipsel architecture, I have done the compilation. It is done well without errors. But i am getting the linking error in compiling the application.

The error is:
/usr/local/Trolltech/QtEmbedded-4.4.1-mips/lib/libQtCore.so: undefined reference to `clock_gettime'

I am using the gcc-3.3.5-glibc-2.3.2 in mipsel-linux platform for cross compiling.

Does the gcc compiler version i am using is supported in the qt4?

Please give me the reason for the linking error and how can i fix it?

Is clock_gettime an attribute or a method of one of your classes?
I am not aware of a method with such a name in any of the Qt classes (especially QTimer where it would fit best).
