Notes

2015b common toolchains: GCC 5.1 or 5.2?

• delay 2015b until GCC 5.2 is there (bugfix release over GCC 5.1)
• implies that 2015b toolchain definitions won't be included in EasyBuild v2.2.0
• can be included in EasyBuild v2.2.1 (mid August'15)

making --robot aware of subtoolchains

• see https://github.com/hpcugent/easybuild-framework/pull/1306
• required enhancements to toolchain definitions are already tackled
• Alan will play around with this further, and report back
• TODO: unit tests, some minor code cleanup (e.g. break into parts a bit more)
• scheduled for EasyBuild v2.3.0 (Sept'15)

outlook to EasyBuild v2.2.0

• support for --include-easyblocks & friends
