MKL Link problem

[jacksonsony]

I am using a linux machine with AMD Opetron running Fedora Core 8.0. The Fortran compiler is the default one coming with FC8, which I believe gcc-gfortran 4.1.2. Most of codes are written in Frotran. If I chose the defult but super-slow math library from the compiler, everything is ok and I can get all my tests passed. However, if I chose MKL, it shows the following error information:

Linker messages (if any) follow...

Any suggestion is highly appreciated.

When you choose intel_thread, you need also libiomp5 and -lpthread. This is discussed in the documentation.
