From dc61dfd7791976c70c93e0d253a8fdbd40d27f3b Mon Sep 17 00:00:00 2001 From: Ralph Siemsen Date: Thu, 14 Apr 2022 14:12:28 -1000 Subject: [PATCH] apt: add -fno-strict-aliasing to CXXFLAGS to fix SHA256 bug Recently we've begun seeing issues with apt SHA256 generation/checking on some distros (fedora 35, alma 8). The version of apt in dunfell uses its own SHA256 code, not a standard library. Investigation reveals that the issue is related to -fstrict-aliasing enabled by -O2 optimization, so turn it off with -fno-strict-aliasing Signed-off-by: Ralph Siemsen Signed-off-by: Steve Sakoman --- meta/recipes-devtools/apt/apt.inc | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/meta/recipes-devtools/apt/apt.inc b/meta/recipes-devtools/apt/apt.inc index ba827848a74..251795eeca3 100644 --- a/meta/recipes-devtools/apt/apt.inc +++ b/meta/recipes-devtools/apt/apt.inc @@ -37,5 +37,9 @@ do_configure_prepend() { rm -rf ${S}/buildlib/config.guess } +# there are code generation issues with some compilers in the SHA256 implementation +# turn off strict-aliasing to avoid these issues +CXXFLAGS:append = " -fno-strict-aliasing" + USERADD_PACKAGES = "${PN}" USERADD_PARAM_${PN} = "--system --no-create-home --home-dir /nonexistent --shell /bin/false --user-group _apt" -- 2.47.3
