vim @7.4.052_0+big: build fails with "conflicting types for 'sigaltstack' "

[bitaxis (Nathan Brazil)]

I am running latest Mac OS X Mountain Lion, latest Xcode (5.0.2). Upgrading vim gives me the following error:

:info:build os_unix.c:830:46: warning: declaration of 'struct sigaltstack' will not be visible outside of this function [-Wvisibility]

Can confirm, I am experiencing this issue. OS X 10.8.5, XCode 5.0.2

[benjamin@…]

Cc Me!

Another confirmation: 10.8.5 and Xcode 5.0.2

Ouch. Still open without reply 6 weeks later?

Sorry I did not answer earlier. I do not see this build error on OS X 10.9 Mavericks and cannot reproduce the problem as I am no longer running OS X 10.8 Mountain Lion.

Initially the build failed on OS X 10.9 Mavericks. This was resolved by #include <AvailabilityMacros.h> that is applied in a local patch (patch-compat-darwin13.diff). Can you confirm that this is required on OS X 10.8 Mountain Lion with Xcode 5 as well?

I can confirm that the patch-compat-darwin13.diff patch is required on Mac OS X 10.6.8 with Xcode 3.2.6. The vim build fails with this error without the patch; it succeeds with the patch.

Okay, thanks for this feedback. If it is also broken in Snow Leopard now without this patch, let's always enable this. Including the header should not harm even if it were not necessary.

As of r116417, the patch for the AvailabilityMacros.h is now included regardless of the version of OS X. Please report back if it is still broken for you.
