Gcc compiler

Hi

How do I redfine the path for the gcc4-0 C compiler downloaded using synaptic package manager (Ubuntu 6.04) so that when I try to compile C++ codes it doesn't keep refering to OpenFOAM?

ie
/home/shuo/OpenFOAM/linux/gcc-4.1.0/bin/../lib/gcc/i686-pc-linux-gnu/4.1.0/../.. /../../include/c++/4.1.0/fstream: In instantiation of 'std::basic_ofstream<wchar_t,> >':

Remove the sourcing of OpenFOAM bashrc script from your local ~/.bashrc, and you're back to the system compiler.

I deleted the last line in the .bashrc file and updatedthe sourcing environment by typing . $HOME/.bashrc. It still gave me the same error message

It's not enough to just rerun your .bashrc, you have to either logout, or close xterm, or start a new xterm.

When I delete the last line in the .bashrc, the utilities ie blockMesh does not work and it can't find the gcc bash command either.

This is very strange, since you say that you have installed gcc. Try to see if it is in /usr/bin/gcc (this is the usual place of the system compiler). If it is there, then it's just a problem with you PATH environment variable, which should include /usr/bin directory.
