* Store ccache directory explicitly in Travis.
Despite we started using ccache on `develop`, it seems the cache itself
is not stored from one CI build to the next. This might be du to the
fact that our language on Travis is Python and not C nor C++.
Hence here we store the ccache directory explicitly.
Lately many CI runs for PRs are failing due to the `mpich` build that
times out on Travis (10 mins. without output). As the timeout seems to
happen consistently during the build phase, increasing the verbosity of
that test can help working around the issue.
The sys_ustat.h.patch to file sanitizer_platform_limits_posix.cc from
PR #10046 does not apply cleanly to gcc 4.8 or 4.9 (or earlier).
GCC up to 4.8.x either don't have libsanitizer or else don't include
ustat.h in sanitizer_platform_limits_posix.cc.
GCC 4.9.x includes ustat.h, but needs a slightly different patch.
The patch applies to GCC 5.x up to 6.4, and 7.x up to 7.3 and also
8.1.0.
The patch is already included in the tar files for gcc 6.5.0, 7.4.0
and 8.2.0.
* flux-sched: fix compilation errors
configure was being run twice becuase the staging symlinks were
confusing autotools
mirror flux-core in building in a subdirectory to avoid other common
compilation problems, like the one in PR #3543
* flux-core: update dependencies
munge is no longer a dependency
provide hints for lua version so that `spack install flux-core` works
"out-of-the-box". Currently, when no explicity version is provided, the
concretizer attempts to use lua@5.3, which is invalid. Closes#10000
* Added a package for the MDAnalysis toolkit.
* Added Ninja as the generator for LBANN, Hydrogen, and Aluminum. Also
fixed a bug in how the Conduit variant is included in LBANN. Added
new versions for Hydrogen and LBANN.
* Updated lbann package so that the CMAKE parameters are set when the
variant is on and off.
Fix the install of the single header amalgate in catch2.
The public API for catch < 2.3.0 was "#include <catch.hpp>".
For 2.3.0+ it is "#include <catch2/catch.hpp>"
