Source: libpsl Version: 0.23.0-1 Severity: wishlist Tags: patch User: [email protected] Usertags: timestamps X-Debbugs-Cc: [email protected]
Hi, Whilst working on the Reproducible Builds effort [0], we noticed that libpsl could not be built reproducibly. This is because the manual page embeds the current build date. The attached patch generates these values from SOURCE_DATE_EPOCH, if it exists. Patch attached that modifies both the Autotools and Meson.build parts, even though I don't think the Meson build system is used right now.
