They were never running anyway since there's no checkout of
tests folder. We should either make tweaks to buildbot master
to make it to send cloning commands for tests folder and keep
tests working (currently some of them are broken).
- Remove deprecated/unused builders
- Remove unused SCons OSX slave configuration
- Remove SCons slave logic, it is not giving error about unknown building
system used for the slave.
No idea why they works on windows, but points are:
- libs/tests folder is NOT checked out on any platforms
- render_povray addon does mkdir on a path which might not have parents
There might be some other issues, but those are kinda stoppers for us.
This is so called "seems to work in dry tests" commit which is aimed to switch
linux release environment to CMake.
Some notes:
- There's no special handle of libstdc++, but it wasn't really static for quite
some time in SCons configuration and nobody really complained.
- It was quite tricky to get OpenMP linked statically with just using some
configuration so we went ahead and added a special option to CMake now which is
only exist on Linux and advertised as shouldn't be used.
- Packing is happening manually in slave_pack.py. This is because we have to add
some really special files to the archive (mesa libraries for example) which we
can't really handle from CMake/CPack in a nice generic way.
Don't think it's bad approach, at least crappynness is localized and it's not
_that_ crappy anyway.
- Windows buildbot should keep working, but needs doublechecing. It's just a
build folder changed, but you never know what it might imply.
- Some further tweaks are likely needed to ensure all builders are working.
Thanks Campbell for assistance in this patch!
