thanks a lot for your help and time. I understood the problem. The makefile adds a -static flag, but on our office machines we don't have static libc.a. Hence, the error "cannot find -lc". I removed the static flag and it works fine for now. I think we don't need a static libc.a, but I will have to check more closely.
