Error(s) that match a know pattern in addition to what has been reported in the summary: FAILED: libampache_browser_1.so.0.0.3 /var/tmp/portage/media-libs/ampache_browser-1.0.3/work/ampache_browser-1.0.3/src/ui/ampache_browser_main_window.h:31:7: error: type ‘struct AmpacheBrowserMainWindow’ violates the C++ One Definition Rule [-Werror=odr] Here is a bit of explanation: -Werror=lto-type-mismatch: User to find possible runtime issues in packages. It likely means the package is unsafe to build & use with LTO. For projects using the same identifier but with different types across different files, they must be fixed to be consistent across the codebase. -Werror=odr: Used to find possible runtime issues in packages. These bugs are a problem anyway but may be even worse when combined with LTO. C++ code must comply with the One Definition Rule (ODR) - see https://en.cppreference.com/w/cpp/language/definition#One_Definition_Rule. -Werror=strict-aliasing: Used to find possible runtime issues in packages. These bugs are a problem anyway but may be even worse when combined with LTO. Workarounds: - If upstream is friendly and still active, file a bug upstream. For emulators, codecs, games, or multimedia packages, it may be worth just applying a workaround instead, as upstreams sometimes aren't receptive to these bugs (VALID FOR ALL). - Use the new 'filter-lto' from flag-o-matic.eclass as it's likely to be unsafe with LTO (VALID FOR lto-type-mismatch - odr). - Fix it yourself if interested, of course (VALID FOR ALL). - Append-flags -fno-strict-aliasing (VALID FOR strict-aliasing). - Use memcpy() but a union is sometimes suitable too (VALID FOR strict-aliasing). - -fstrict-aliasing is implied by -O2, so this must be addressed in some form (VALID FOR strict-aliasing). See also: https://marc.info/?l=gentoo-dev&m=165639574126280&w=2 I have fixed the issue in upstream and created a pull request which adds the new version (1.0.4) (https://github.com/gentoo/gentoo/pull/26590). After a stabilization period 1.0.4 will be stabilized and 1.0.3 removed.
