Different build paths trigger reproducibility issues with binaries such as /usr/bin/BAGEL and relevent debugging symbols. The attached patch fixes this by passing -ffile-prefix-map to CXXFLAGS to avoid embedding the build path into the binaries. Another possibility would be to use dpkg-buildflags, which includes this flag by default. With this patch applied, bagel should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining bagel! live well, vagrant

The -ffile-prefix-map argument is used to avoid embedding the build path in binaries, which allows for reproducible builds regardless of the build path in the build environment. --- debian/rules | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/debian/rules b/debian/rules index 62d1d08..b6e0afa 100755 --- a/debian/rules +++ b/debian/rules @@ -3,7 +3,7 @@ export LIBS=-lblas -llapack -lpthread -export CXXFLAGS=-g1 -O2 -DNDEBUG -DZDOT_RETURN +export CXXFLAGS=-g1 -O2 -DNDEBUG -DZDOT_RETURN -ffile-prefix-map=$(CURDIR)=.
