Source: gcc-13 Version: 13.1.0-2 Severity: normal Tags: patch User: reproducible-bui...@lists.alioth.debian.org Usertags: timestamps X-Debbugs-Cc: reproducible-b...@lists.alioth.debian.org
The build dates and timestamps are embedded in various files shipped in documentation. The attached patches fix this by adding SOURCE_DATE_EPOCH support to the doxygen scripts used to generate the libstdc++ documentation, and by adjusting debian/rules2 to remove the leftover _formulas.log files from the generated package. According to my local tests, applying these patches should allow gcc-13 to build reproducibly with stable build paths and DEB_BUILD_OPTIONS="nocheck nolto nopgo". Thanks for maintaining gcc-13! live well, vagrant
