Match git commit
I think the version you checked out of git has a modified Foam::dlopen routine.
For the patch to work correctly you need to match the exact version of OpenFOAM from git.

Try replacing "gpu" with "libgpu.so"
Another thought, try replacing "gpu" in controlDict with "libgpu.so" - though this shouldn't be necessary. I suggest this because the dlopen error message shouldn't be reported in it's raw form, at...

gpu in controlDict is correct
It's correct to load libgpu.so ("gpu" in your controlDict) and I was thinking that given libgpu.so is in the right location, it is more likely that libofgpu.so (which libgpu.so references) was not...

Another thought.
You have to supply your settings "WM_GPU='CUDA' CUDA_ARCH_PATH=/home/roman/OpenFOAM/ofgpu-0-2"
as args to etc/bashrc e.g.,:
export FOAM_INST_DIR="$(HOME)/projects/of/of2.0";...

The problem you are seeing is a symptom (not the cause) related to missing lnInclude directories....

Don't define FOAM_LABEL_64

I can't see where this is defined by default. It's not about whether you are compiling 64-bit, it relates to the size of integers. If you can find where it's defined I...

Foam::label as long, why?
So I guess on your system (Linux?) you have Foam::label defined as a long?
That would result from defining 'FOAM_LABEL_64' for label.H
Is this the case?
Do you really need access to integers...

Thanks for your supportive comments. I just wanted to clarify that at present ofgpu only supports a single CUDA device, i.e., no clusters.
