Notes

EasyBuild v2.0 update
  • all planned changes in EasyBuild framework have been merged into develop
  • a couple of documentation updates must be tackled before EasyBuild v2.0 can be released (major ones are already tackled)
  • see https://github.com/hpcugent/easybuild-framework/issues/1000 for all details
  • full regression test revealed only one major problem w.r.t. mpi_cmd_for function affecting several builds (HPCG, NAMD, NEURON, WRF (+ WPS))
Early outlook to EasyBuild v2.1
Consider robot search path when looking for easyconfigs specified on the command line
  • see discussion on EasyBuild mailing list (https://lists.ugent.be/wws/arc/easybuild/2015-02/msg00039.html)
  • no good reason why eb wouldn't consider robot search path for easyconfig files specified on cmdline
  • conf call attendees agree it would be a sensible/good change to make that happen
  • would be nice to get that included for EasyBuild v2.0
Dummy vs system toolchain
  • dummy toolchain was never meant to be used directly, other than for (building and) installing compilers
  • (build) dependencies are not loaded when version of dummy toolchain is non-empty (e.g. set to dummy)
  • EasyBuild framework doesn't set up a proper build environment when a dummy toolchain is used
    • e.g. CC=dummy, no $CFLAGS defined, toolchainopts is ignored, etc.
  • a proper system toolchain should be looked into
  • system-gcc should be quite easy to do introduce, since good GCC support is already there
