Hi all, I am struggling a little to get Rosetta and phenix to play happily with one another (I’d like to use the phenix.rosetta_refine module). I am currently using the latest nightlies of phenix (1.9-1690) and rosetta (2014.16.56682), and I run into errors (reproduced below) when attempting to build the phenix-rosetta interface. Does anyone have any insights as to how to fix this problem, or suggestions as to which pair of phenix and rosetta versions are known to be compatible with one another? Many thanks, Oliver.
