Re: Mac OS X nightlies are up!

 

I wonder whether the idea of the Nightlies is being torn between two goals:

1) Having a system that more or less 'all' Mac users can use.
2) Doing bleeding edge build/tests on the latest repository changes.

Just an observation.

Homebrew has a feature built in for building for "oldestmac".  I need
to figure it out, but this should be fixed in our nightlies in the
next few days.  I'll let everyone know when our Core 2 users should
retest.

Thanks everyone!

    There is more to tweak if you want to squeeze out every last
    option, but in general it should be pretty much OK to use I guess.

    I never was sure though, if passing a “-march=xxx” via CFLAGS will
    prevent additional checks used in some configure.sh to use
    something that the real CPU allows but “-march=xxx” wouldn’t (and
    you would have to supply additional —disable-xxx flags to
    configure.sh).

        Does anyone on this list own a Core Duo mac?  If so I'd like
        to just steal the flags that system uses...

            Hi,

            sounds all reasonable and clear, Garth. Thank you for the
            explanation!

            Personally, I have no problem in building my own version
            from the sources, but I think there
            are still quite a bunch of Core2s in Apple machines out
            there, so perhaps the nightlies
            should go for a more backwards compatibility than i5 and
            siblings.

            Looking here,

            https://github.com/Homebrew/homebrew/blob/master/Library/Homebrew/os/mac/hardware.rb

            it seems that Homebrew indeed makes different choices for
            -march depending on the CPU type
            found. So, I think the "best arch for compatibility" then
            would probably be the oldest intel
            CPU found there, which seems to be Core Duo.

            Another solution would of course be to simply state in
            the README that the nightlies won't
            work on machines lower than i5. As I said, I have no
            problem in building Kicad myself. I just
            wanted to report my experience with the nightlies, which
            are nonetheless a great improvement
            for new, unexperienced Mac OSX users.

            So again, thank you all for your great work and help!


            Best,
            Johannes

            Note, I cleanly rebuild *everything* every time,
