Package: agg Version: 1:2.6.0-r132+dfsg1-2 Severity: minor Tags: patch User: ubuntu-de...@lists.ubuntu.com Usertags: origin-ubuntu disco ubuntu-patch
Hi John, The latest version of agg, 1:2.6.0-r132+dfsg1-2, fails to build from source on ppc64el in Ubuntu due to a difference in the symbols output for the shared library. This is because Ubuntu defaults to -O3 on ppc64el, which means some additional template symbols are omitted from the output that are otherwise seen when building with -O2. Since these are template symbols and not part of the shared library ABI, a correct fix to make the library compatible with -O3 is to mark these symbols optional as in the attached patch. Please consider applying in Debian. Thanks, -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.
