McXtrace: mpi.h and gsl headers not found on MacOSX

[ebknudsen]

It would appear that they have somehow not been added to the miniconda-installation.
investigating further...

[ebknudsen]

The Check-PY-dependencies script cannot find orted nor orterun so something must be missing

Could you please try putting a McStas 2.6 on the same machine also?

I am quite sure I ran with MPI without issues on macOS with that release.

McStas 2.5 is on the machine and it works, so it is McXtrace only. Trying to see what the differences can be. My guess is something went south during packaging, so mpi and gsl did not get conda'd. That's the current theory.

[willend]

Sounds plausible. May be worth to cross-check versions of conda?

With a little luck you may be able to

conda install openmpi gsl

Weird, everything works on my machine??

Didn't try anything GSL - which instr should I test?

I may also remove my current 1.5 and install anew...

[ebknudsen]

Indeed I can confirm that the workaround works, i.e.

• File -> Open Terminal env.
• conda install gsl openmpi

[willend]

I believe this is fixed by d0b57aa - so that an updated McXtrace should work in this respect

[ebknudsen]

This workaround should simply be verified. Then closed :-)
