[scipion-users] Xmipp workflow test failure

[John H. <joh...@co...>]

Greetings!

I recently installed the v1.1_2017-06-14  binaries on a RHEL7 system.  
None of the additional packages are currently installed. All of the 
small tests pass except 2 which seem to be using eman components (not 
installed), so I'm ignoring those. The Xmipp workflow test failed at the 
ML2D step, however. The stdout log indicates failure to load 
libmpi.so.1. It's not surprising that it can't find libmpi.so.1 since 
the current version is libmpi.so.12.0.6. As a temporary workaround I 
made a symbolic link libmpi.so.1 -> libmpi.so, which, in turn, points to 
libmpi.so.12.06. The test passes after this kludge.

Why is this test trying to load a specific, older version of the mpi 
library? Isn't  the core functionality in the newer versions backwards 
compatible?  Would I avoid this problem if I build from source myself? 
Or have I configured something incorrectly?

Thanks in advance!

Regards,
