Bug 870007 – x11-libs/cairo-1.16.0-r5: fails to compile with Clang 15 (error: "XXX: No mutex implementation found. Cairo will not work with multiple threads. Define CAIRO_NO_MUTEX to 1 to acknowledge and accept this limitation and compile cairo without thread-safe)

• Status: RESOLVED OBSOLETE
• Product: Gentoo Linux

Likely that this is some configure test gone wrong b/c of Clang 15's changes to -Werror implicit function declarations (and implicit int, and K&R prototypes).

[Comment 2 listout 2023-05-11 19:00:15 UTC]

cairo-1.17.8 seems to build fine, cairo-1.16.0 doesn't seem to be in tree anymore.

[Comment 3 ernsteiswuerfel 2023-08-29 00:34:29 UTC]

As listout mentioned in comment #2 current stable cairo-1.17.8 builds fine with clang-16.

So closing here.
