It's SuSE 9.2.
Although I have programmed in c++, I am not an expert. Therefore, I might be 
missing something. But when I tried to locate the unresolved symbols I found 
e.g. in include/SV_number.h

struct cl_SV_number : public cl_SV<cl_number,cl_SV_any> {
...
};

Why "struct"? Shouldn't it be a class? I just changed it to "class" and at 
least it is compiling (although in the library the symbol is still missing)

So would I. I'd like to do some Galois field computations, that's how I came 
to try cln.
