| Summary | 0033091: Build failure with LTO (-Werror=odr) | ||||
| Description | There's no category related to building the software. Feel free to move to a desired category, if I've chosen the wrong. I received a bug report[1] where building v7.6.2 fails when LTO is used. The issue is about the One Definition Rule of modern C++ standards: FAILED: lin64/gcc/libi/libTKXCAF.so.7.6.2 /var/tmp/portage/sci-libs/opencascade-7.6.2-r1/work/occt-V7_6_2/src/XCAFDoc/XCAFDoc_Datum.cxx:37:6: error: type ‘ChildLab’ violates the C++ One Definition Rule [-Werror=odr] You can find a complete build log attached to the bug report on bugs.gentoo.org. If desired, I can upload the log file here as well. Building with LTO is currently undergoing a systematic test review on Gentoo, so this issue is probably not new, but was just unrecognized as a warning, if people were already using LTO. I can filter out such flags as a quick hack, but for the long term it would be more interesting what your plans are for LTO strictness of future releases.
