Building Error: relocation truncated to fit: R_X86_64_32S against symbol 'XXX'

 This error denotes mixing of small and medium memory model object files. Even if Pleides had more memory per node it would still appear. The solution is either:
a) Stick to less than 2GB of RAM per process and make sure that you are only using small memory model object code (no -mcmodel=medium flags for compiling and no libraries created with that flag).
b) If you plan to use more than 2GB of RAM per process compile everything with -mcmodel=medium and make sure all libraries have also been compiled with -mcmodel=medium or -fPIC.
c) Or compile everything with -fPIC and make sure you are not linking any static libraries compiled without -fPIC.
