Hello,

I would like to compile OpenFOAM on my Gentoo x86 linux box from scratch.
The machine has gcc-4.1.1, paraview and java already installed. I am NOT willing to install them again within OpenFOAM (as the wiki page recommends).

I am fighting with the bashrc and cshrc files in OpenFOAM-1.3 and OpenFOAM-1.3/.OpenFOAM-1.3 directories, where PATHS and other environment variables are defined.

Does anyone know how to modify these files in a clean, simple and efficient way in order to use the gcc, binutils, java etc. already installed on a Linux system?

Hi Daniel!

I think the easiest way to use the system-installed gcc etc is to just not install the OpenFOAM-supplied gcc (or move it to a location not in the paths). Then there are some unused entries in the PATH-variables, but that doesn't hurt anyone.

Hello Daniel, Regarding gcc
 
Hello Daniel,

Regarding gcc, you can use system gcc by defining as follows in ${WM_PROJECT_INST_DIR}/OpenFOAM-1.3/.bashrc

WM_COMPILER_DIR=/usr

it will be valid if your system gcc is in /usr/bin

As for binutils, it will depend on your distribution. All you need to take cake seems to be "demangle.h"

Anyway, please study OpenFOAMWiki well.
