A Problem encountered when source ~/.bashrc, Please.
 

Hello, my dear friend, I am pretty new to linux and OpenFOAM, once I unpacked all stuffs, and added to the bottom of ~/.bashrc ". $HOME/OpenFOAM/OpenFOAM-1.5/etc/bashrc", I sourced the ~/.bashrc, then it returns something concerning the gcc like below,

Cannot find /home/limiao/OpenFOAM/ThirdParty/gcc-4.3.1/platforms/linux installation.
Please install this compiler version or if you wish to use the system compiler,
change the WM_COMPILER_INST setting to 'System' in this file

would it be possible that you guys let me know what this means and what I need to do? Thanks a lot!
