Package: hello Version: 2.8-4 Severity: wishlist Tags: patch Hi!
In the quest to get deterministic/reproducible builds [1], I have noticed that the result of building hello currently varies according to its build path. The attached patch use the debugedit tool to prevent such variation by relocating the source associated with the debug data to a deterministic path. It also adds `-fno-merge-debug-strings` to the CFLAGS, because the resulting .debug_str section will be different depending on the initial input strings. This behaviour should eventually be fixed at the compiler level. [1] http://wiki.debian.org/ReproducibleBuilds Thanks, -- Lunar .''`. lu...@debian.org : :Ⓐ : # apt-get install anarchism `. `'` `-
