The build path is embedded in various files: https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/gmp.html /usr/include/x86_64-linux-gnu/gmp.h #define·__GMP_CFLAGS·"-g·-O2·-ffile-prefix-map=/build/1st/gmp-6.2.1+dfsg=.·-fstack-..." vs. #define·__GMP_CFLAGS·"-g·-O2·-ffile-prefix-map=/build/2/gmp-6.2.1+dfsg/2nd=.·-fstack-..." /usr/lib/x86_64-linux-gnu/libgmp.so.10.4.1 /build/1st/gmp-6.2.1+dfsg/build/mpn/tmp-add_n.s:97 vs. /build/2/gmp-6.2.1+dfsg/2nd/build/mpn/tmp-add_n.s:97 The attached patches fix this by replacing the build path with "BUILDPATH" from in debian/rules, and passing a --debug-prefix-map argument to use relative paths via ASMFLAGS in configure. With these patches applied gmp should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining gmp! live well, vagrant

The absolute build path can be embedded in generated assembly code. Instead, passing --debug-prefix-map is used to adjust the absolute paths to relative paths within the source code. https://tests.reproducible-builds.org/debian/issues/build_path_captured_in_assembly_objects_issue.html --- debian/rules | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/debian/rules b/debian/rules index 164d9e3..905d95b 100755 --- a/debian/rules +++ b/debian/rules @@ -89,7 +89,7 @@ configure-stamp: mkdir -p build cd build && ../configure $(confflags_ma) \ AR=$(AR) CC="$(CC)" CFLAGS="$(CFLAGS)" \ - CXX="$(CXX)" CXXFLAGS="$(CXXFLAGS)" + CXX="$(CXX)" CXXFLAGS="$(CXXFLAGS)" ASMFLAGS="--debug-prefix-map=$(CURDIR)=." touch $@ build: build-stamp -- 2.35.2
