The build time is embedded in various binaries: https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/device-tree-compiler.html /usr/bin/convert-dtsv0 /build/1st/device-tree-compiler-1.6.1/srcpos.c:101 vs. /build/2/device-tree-compiler-1.6.1/2nd/srcpos.c:101 The attached patch to debian/rules fixes this by passing the default CFLAGS via EXTRA_CFLAGS, which includes the -ffile-prefix-map compiler option. According to my local tests, with this patch applied, device-tree-compiler should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining device-tree-compiler! live well, vagrant
From 77ddff89156eb55a550238a490e58023476c8efa Mon Sep 17 00:00:00 2001 From: Vagrant Cascadian <vagr...@reproducible-builds.org> Date: Sun, 16 Oct 2022 18:02:45 +0000 Subject: [PATCH] debian/rules: Pass default CFLAGS via EXTRA_CFLAGS. commit 13c4c940e65039052b5be499a848aaa9ffaffaa7 "Enable pylibfdt build (Closes: #877125)" introduced a regression by removing the default CFLAGS. This triggered reproducible builds issues with embedded build paths, because -ffile-prefix-map was no longer getting passed to the compiler. The pylibfdt build system ignores CFLAGS, but respects EXTRA_CFLAGS, so pass all CFLAGS via EXTRA_CFLAGS. --- debian/rules | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/debian/rules b/debian/rules index b146728..5aae1d5 100755 --- a/debian/rules +++ b/debian/rules @@ -15,7 +15,7 @@ export CC = $(DEB_HOST_GNU_TYPE)-gcc endif include /usr/share/dpkg/buildflags.mk -EXTRA_CFLAGS = -Wno-error +EXTRA_CFLAGS = $(CFLAGS) -Wno-error CPPFLAGS += -I libfdt -I . %: -- 2.37.2
