[Mochi-devel] Mochi on Summit

[Dorier, Matthieu]

Hi,

You can uninstall the version that was compiled with gcc 4.8 by doing
spack uninstall margo %gcc at 4.8.5
or
spack uninstall margo /t3x4fur

Make sure that spack uses gcc 6.4.0 by default since many of the Mochi libraries won’t compile with 4.8.

Thanks,

Matthieu

Hello,

I am trying to play with Mochi on Summit. I installed it using Spack. It was successful. However, when I use spack load -r margo I got the following error:

[amalik at login5.summit mochi]$ spack load -r margo
==> Error: the constraint '['margo']' matches multiple packages:
t3x4fur margo at 0.5.2%gcc at 4.8.5 arch=linux-rhel7-power8le
gniufvt margo at 0.5.2%gcc at 6.4.0 arch=linux-rhel7-power9le

==> Error: In this context exactly **one** match is needed: please specify your constraints better.

I think it is confused by the availability of two compilers. How should I solve this issue?
