Hello

I am trying to compile openfoam on ubuntu-fiesty fawn.
I am using gcc-4.1, and have followed the instructions on the openfam website and README exactly. But i get these strange ld errors.
I would appreciate it if someone could help me with this.

Regards
Srinath

Hi Srinath,

A short question.... which version of GNU GCC are you using for compiling OpenFOAM?

If you are using GCC-4.2.2 as asked for in the OpenFOAM "buildinstructions.txt", are you sure you sourced the .bashrc file after you made the required changes to it ?

Personally, thats one of the most common things that hit me.... forgetting to source the latest .bashrc.

I have resorted to always closing the console and opening a new one (so that the .bashrc gets sourced, and all the changes are activated), before finally starting the actual OpenFOAM compilation with the "./Allwmake" script.

Probably you could check with a "gcc --version" on the console to make sure you are actually using the version of gcc you think you are using.

Have a nice day!
