Description Fabian Vogt 2024-02-06 13:40:13 UTC 
Before RPM 4.19, the .spec file had

%ifarch %arm
BUILDTARGET="--build=%{_target_cpu}-suse-linux-gnueabi"
%elifarch x86_64 %x86_64
BUILDTARGET="--build=x86_64-suse-linux"
%else
BUILDTARGET="--build=%{_target_cpu}-suse-linux"
%endif

This is now gone and I don't see a way to easily do that with cmake.

The result is that for e.g. armv7hl, the host macros changed:

Before:

%_host                  armv7hl-suse-linux-gnueabi
%_host_alias            armv7hl-suse-linux-gnueabi%{nil}
%_host_cpu              armv7hl
%_host_vendor           suse
%_host_os               linux

After:

%_host                  armv7l-suse-linux
%_host_alias            armv7l-suse-linux%{nil}
%_host_cpu              armv7l
%_host_vendor           suse
%_host_os               linux

This means that binaries built for armv7hl have the wrong %_host specified, whic h is also used in %configure to set --host.

The specfile contains
%ifarch %arm
  -DRPMCANONGNU=-gnueabi \
%endif

instead. I'm pretty sure I checked that this worked at some point in time.

That part works, but it only changes %_gnu in /usr/lib/rpm/platform/*/macros.

Hmm, it worked for the %_gnu, but never for %_host. Fixing...

Note that it's not the -gnueabi part that matters most here but the armv7l vs armv7hl.
