Hi Florian,

It seems that some Ubuntu users (including me) are having problems when compiling SPheno. In Ubuntu, Binutils has the deterministic mode enable by default, which recompiles all the files every time you run SPheno.

I modified the files SARAH/Package/SPheno/SPhenoLesHouchesAndMake.m and SPheno/src/Makefile to solve the problem.

One have to replace all the "ar -ruc" with "ar -ruc -U" in both files, adding the U flag to disable the deterministic mode manually.

Cheers!

Thanks a lot for that information!
