Hello everybody,

I am trying to compile OpenFOAM on a PC (linux, red hat 7.3)and I get some error messages related with some libraries, I include an example of such errors:

--------------------------------------------------
/home/ceis/OpenFOAM/OpenFOAM-1.0/src/lam-7.1.1/platforms/linuxOpt/lib/liblam.so.0: undefined reference to `pthread_cond_signal@GLIBC_2.3.2'

collect2: ld returned 1 exit status
make: *** [/home/ceis/OpenFOAM/OpenFOAM-1.0/applications/bin/linuxOpt/icoTopoFoam] Error 1

--------------------------------------------------

any idea that helps me to solve this will be welcome.

Thanks in advance.

Hi,

did you clean out the lam build? See the $FOAM_SRC/Allwmake script for how to clean/rebuild lam.

Also I've never tried to build that lam version on an older RH version. OpenFOAM uses an unmodified lam and just does something like configure --prefix=XXXX so it seems the error is in the lam configure setup. Or there are some old binary files which haven't been removed.

Hope this helps,

Mattijs

Hi Mattijs,

You are right, I have erased the whole instalation, I have installed it again but without installing the precompiled version, I have recompiled it and it works perfectly.

thank you very much.

Enric.
