FOAM installation compiler issues

Hello,

I am totally new to both OpenFoam and Linux Ubuntu, which is the OS I'm using. I'm probably pretty computer-illiterate compared to most of you lot!

I've had endless problems so far, but the latest one is something to do with gcc compiler (I don't really know what that is).

The excerpt from the InstalltionTest is below. I'd be very grateful for any advice please!

Thank you

Gareth

Hello Gareth,
Is it possible that you unpacked only the sources (OpenFOAM-1.5.General.gtgz)?
If so, you must unpack the binaries, too (OpenFOAM-1.5.linux64GccDPOpt.gtgz).
The order is or used to be important (first sources, second binaries).

I hope this is helpful,
Dragos

Hi Gareth,

It looks like your installation is set to 32 bits. If it is what you really want, then you'll need to download the 32 bits binaries from this web page:

http://www.opencfd.co.uk/openfoam/linux.html

If your computer is 64 bits, then unset the $WM_32 variable in your .bashrc.

Dragos - yes, it's all unpacked. Thanks

Matthieu - thanks for that, it sounds promising. Is it in the $HOME/.bashrc? How do I 'unset' it?

mathieu · February 9, 2009, 11:52

Just comment this line:

# export WM_32=1

in the $HOME/.bashrc file.

I don't have that line in the $HOME/.bashrc file!?

dmoroian · February 9, 2009, 12:38

I think he meant in $HOME/OpenFOAM/OpenFOAM-1.5/etc/bashrc

Does this commands:

echo $WM_ARCH

returns " linux " or " linux64 " ?

Typing " wm64 " in a terminal should set your environment in 64 bits. Thus try the following in a terminal:

wm64
