gnome-desktop @3.38.0: unknown type name 'uint64_t'

[chrstphrchvz (Christopher Chavez)]

Build fails on ​10.8 and earlier:

../gnome-desktop-3.38.0/libgnome-desktop/gnome-rr.h:78:5: error: unknown type name 'uint64_t'
    uint64_t matrix[9];
    ^
1 error generated.

I think this might be an upstream code problem, i.e. the code should be using its conventional types, e.g. guint64; this seems more likely than it missing #include <stdint.h>, which it doesn't do anywhere else. A similar issue might exist in gnome-desktop-thumbnail-script.c, which is using uint32_t likewise without <stdint.h>.

[dbevans (David B. Evans)]

Yes, but the question is this: Why does it fail only on 10.8 and earlier? That would make me think that it is an outdated compiler/library problem.

[kencu (Ken)]

Worked for me on 10.6.8:

$ port -v installed | grep gnome-desktop
  gnome-desktop @3.36.6_0 (active) platform='darwin 10' archs='x86_64' date='2020-09-13T05:38:31-0700'

I don't recall doing anything fancy about it.

[kencu (Ken)]

Oh, wait - -that was 3.36.6 -- looks like it was updated again in the past few days. I'll try 3.38.

[dbevans (David B. Evans)]

Yes, its the latest version that's having the problem.

Replying to dbevans:

Yes, but the question is this: Why does it fail only on 10.8 and earlier? That would make me think that it is an outdated compiler/library problem.

I think it could be that newer compilers are instead lenient about using uint64_t etc. without #include <stdint.h>. (Unless the compilers are old enough to lack C99 support, which ​shouldn't be the case here.)

[kencu (Ken)]

10.6.8 uses a compiler newer than Xcode 11's. It's in the older headers somewhere (some newer header in 10.9+'s SDK probably includes it).

I did this:

and that was all it needed to build.

[chrstphrchvz (Christopher Chavez)]

Pending action upstream, I would go with applying Ken's patch (no revbump needed). Nothing appears to be necessary for gnome-desktop-thumbnail-script.c because it isn't being compiled.
