mpv @0.5.0: You manually enabled the feature 'cocoa', but the autodetection check failed.

[ryandesign (Ryan Carsten Schmidt)]

On the Snow Leopard buildslave mpv fails to configure:

Checking for Cocoa                                                        : no

I suppose there is no way to check the logs, as the bot cleans the workdir after failure?

[ryandesign (Ryan Carsten Schmidt)]

Correct, and the buildslaves' filesystems are not accessible to us in any case. We would have to try to build it ourselves on a Snow Leopard machine. Which I've done, and I'm attaching the main.log and config.log from that. The reason why the cocoa test fails seems to be:

.../mpv-0.5.0/osdep/macosx_compat.h:44:18: error: missing binary operator before token "("

Line 44 of macosx_compat.h is:

#if __has_feature(objc_bool)

More like

/Volumes/Data/macports/snowleopard/var/macports/build/_Volumes_Data_macports_dports_multimedia_mpv/mpv/work/mpv-0.5.0/osdep/macosx_compat.h:44:5: warning: "__has_feature" is not defined

__has_feature is only available in clang.

Seems like I have to blacklist *gcc* and prefer clang-3.4 (any other clang may do as well, but if no clang is available, prefer 3.4 for now.)

Maybe-fix for SL issue.

[Ionic (Mihai Moldovan)]

If possible, please apply this before #45302 to see whether the SL build bot finishes successfully.

Just using clang is not enough. The cocoa interface will only work 10.6 if ARCLite is available within Xcode. Unfortunately, ARCLite is only available in Xcode 4.2, which was a paid update at that time and can even retrospectively only be downloaded by paid OS X developers ($99/a.) We can neither put this burden on the buildbots, nor 10.6 users.

The latest, freely-available Xcode version for 10.6 is 3.2.6, which does not support ARCLite.

Two options now:

• disable the cocoa output on 10.6 and force the x11 output (does this really make sense?)
• completely disable mpv on 10.6 and below.
