Created attachment 339892 [details] =media-libs/libaacplus-2.0.2 build log
Created attachment 354608 [details, diff] sample patch for libaacplus-2.0.2-r1.ebuild I have confirmed that can be compiled on Gentoo/FreeBSD.
Still in clang 3.3
Created attachment 382686 [details, diff] Fix frontend/au_channel.h to use static inline functions. Fixes the compilation by using the "static" keywords for the functions in frontend/au_channel.h. Described as the simplest portable pratice here: http://www.greenend.org.uk/rjk/tech/inline.html Tests pass fine both with clang-3.4.2 and GCC 4.8.3, libaacplus-2.0.2-r2.
The patch for the static keywords should be applied with clang-3.5.0 as well. I can confirm that with the patch it is *not* required to add std=c99 to make the build succeed.
Tested with GCC 4.9, 5.3 and clang 3.7.1, thanks! commit f41b6ee954d6b66c8bcc405e5c87d13d6de0bd56 Author: David Seifert <soap@gentoo.org> Date: Fri Feb 5 23:16:47 2016 +0100 media-libs/libaacplus: Include patch for building with clang Gentoo-Bug: 458932 * EAPI=6 * Thanks Fabio Scaccabarozzi for the patch
