by the way my OS is Linux Suse 10 and the processor is AMD Athlon (tm) XP 1500+

I guess you should install gcc 4.0.1 (or 4.0.2). It's requiered while compiling from source.
You can find all the stuff you need here http://www.opencfd.co.uk/openfoam/linuxAMD64.html
The question is, why compiling from source, when you already have the binary pack?

Hi thanks,
I am new user of linux too. i downlaoded all from http://www.opencfd.co.uk/openfoam/linuxAMD64.html.
and when i tried to install i got the error.
for the binary pack i dont know how to install openfoam using binary pack. need some help

[mattijs]

Download all those files and put them in exactly that directory structure (http://www.opencfd.co.uk/openfoam/linuxAMD64.html)

Unpack all so
tar xzf OpenFOAM-1.2.General.gtgz
tar xzf OpenFOAM-1.2.linuxAMD64Gcc4Opt.gtgz
..

You should end up with a directory structure like:

OpenFOAM/
OpenFOAM-1.2/
linuxAMD64/
gcc-4.0.1/
paraview-2.2.0/
j2sdk1.4.2_05/

then source the startup file:

. ~/OpenFOAM/OpenFOAM-1.3/.bashrc

Dear Mattija,
i did that. i have 2 folders inside OpenFOAM folder OpenFOAM-1.2 & linuxAMD64. i did all as in the website, but it seems during tht installation OpenFOAM reads the gcc complier and java from /usr/local/bin/gcc instead of /home/user/OpenFOAM/linux/gcc-4.0.1/bin/gcc
read the installation message down please.
also i wonder why the installation test reads linux and not linuxAMD64. if you ask me, which version i downloaded i will say it is from here http://www.opencfd.co.uk/openfoam/li...tml#linuxAMD64

If you check your PATH environment variable you will probably be able to deduce yourself what is going on.

Dear Niklas,
i am not that experter in linux, can you please tell me where to check and modify if possible my PATH environment.
regards

[niklas]

Then I would say that the problem is your Linux skills.
if you write
echo $PATH
you will see in which directories your setup is looking
for your executables.
Do you find the OpenFOAM directories there and are they after/before the /usr/bin path.
Only YOU can setup your system and if you dont speak *nix it will be very difficult help you.

add

export WM_64=1

to your .bashrc. This will force it to pick up your 64 bit installation.

Or install the 32 bit version.
