New question #233320 on Yade:
https://answers.launchpad.net/yade/+question/233320

I want to compile yade with quad precision (-DCMAKE_CXX_FLAGS="-DQUAD_PRECISION"). my nummerical stability problem is still not solved. I tried it with some different fitness function. this reduces the impact of the instability, but solves not the problem. So I need more precision. 

While compiling yade I get some of these errors:

/home/yade/trunk/pkg/dem/MicroMacroAnalyser.cpp:141:61: Fehler: keine passende Funktion für Aufruf von »min(const result_type&, long double)«

I know i want to use an experimental feature. But is there a version which could be build with this option, or must I repair the code be hand.
