Bug 483408 – =x11-libs/cairo-1.12.16 with sys-devel/clang - /usr/include/libiberty.h:616:12: error: expected parameter declarator extern int asprintf (char **, const char *, ...) ATTRIBUTE_PRINTF_2;

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Stefan de Konink 2013-09-02 16:29:54 UTC]

Cairo seems to raise specific issues with system headers while compiling util/cairo-trace. When I disable the compilation of cairo-trace in its Makefile the build is succesful.

Reproducible: Always

Remove libiberty include from util/cairo-trace/lookup-symbol.c

[Comment 8 Fabio Scaccabarozzi 2014-08-09 13:23:58 UTC]

Clang seems to be stricter than GCC as far as #includes go.
I have attached a patch that removes the libiberty.h include from util/cairo-trace/lookup-symbol.c. This makes the file compile. Both bfd.h and libiberty.h pull in ansidecl.h, which makes clang think there is a redefinition of the same objects. Compilation is now fine, I have yet to test run the program (cairo-trace) properly because I'm working remotely (needs a graphic environment to start applications for which to trace calls).
Note that cairo *still fails tests* with both clang-3.4.2 and GCC 4.8.3, which makes me think it's not a clang issue.

[Comment 9 Fabio Scaccabarozzi 2014-08-09 13:27:02 UTC]

Addendum: The program runs fine when invoked as "cairo-trace --help".
I couldn't find references of the problem being already fixed on the web, and I'm using binutils-2.24-r3.

What is the status of this with 1.14.6?

[Comment 11 Fabio Scaccabarozzi 2016-06-07 21:06:40 UTC]

I'm still hitting this with cairo-1.14.6 and clang/llvm-3.8.0.
Applying the patch I posted is still solving the issue for me.

[Comment 12 Chí-Thanh Christopher Nguyễn 2016-06-07 21:50:46 UTC]

The patch was not sent upstream from what I can tell, this would be the first step to get it applied.

Even though the upstream bug is still open, I can currently compile x11-libs/cairo-1.14.8 and x11-libs/cairo-1.14.10 with clang-3.9.1 without applying any patches. Test suite passes (as long as I remove RESTRICT="test",  should not be there in the first place, since it's only set to prevent circular dependencies, but that's another story).

Should this bug be closed?

I think so. It also works for me with cairo-1.14.12 and clang-6.0.1.
