hi i changed a file called TensorI.H in the primitives/Tensor directory now i want to compile it so that the nonlinear k-epsilon model is working right. for compiling i typed wmake libso in /OpenFOAM/OpenFOAM-1.4.1/src/OpenFOAM. as error i got:

maybe someone can fix that problem. i am working on an ubuntu system and using opfoam 1.4.1. i already installed binutils-dev for ubuntu.

Have you installed a regular (non-OpenFOAM g++)? In my experience, although it won't be used, this makes problems like this go away.

The other guess (I remember that vaguely) is that the OF-g++ at least needs the glibc-devel. Maybe installing that helps. (But that is the kind of stuff that gets installed when you install a regular g++, see above)
