Re: fltk rebuild issue: uname -i "unknown"?

[Vincent Mihalkovic <vmihalko@xxxxxxxxxx>]

Hello,

from related https://bugzilla.redhat.com/show_bug.cgi?id=2121153#c1 (fltk bugzilla):

     "It should use `uname -m` rather than `uname -i`, which has been documented as non-portable since 2015"

I haven't paid much attention to the fltk package since Rex is the primary maintainer but I just attempted to build fldigi and ran into the following issue:

checking for fltk-config... /usr/bin/fltk-config

/usr/bin/fltk-config: line 3: exec: fltk-config-unknown: not found
configure: error: /usr/bin/fltk-config failed

From a local rebuild attempt of fltk I see:

+ mv /builddir/build/BUILDROOT/fltk-1.3.8-3.fc38.x86_64/usr/bin/fltk-config /builddir/build/BUILDROOT/fltk-1.3.8-3.fc38.x86_64/usr/bin/fltk-config-unknown

+ install -p -m755 -D /builddir/build/SOURCES/fltk-config.sh /builddir/build/BUILDROOT/fltk-1.3.8-3.fc38.x86_64/usr/bin/fltk-config

Which seems strange until I took a loot at the FLTK specfile:

# we only apply this hack to multilib arch's

%ifarch x86_64 %{ix86} ppc64 ppc s390x s390 sparc64 sparc
%global arch %(uname -i 2>/dev/null || echo undefined)
mv $RPM_BUILD_ROOT%{_bindir}/fltk-config \
   $RPM_BUILD_ROOT%{_bindir}/fltk-config-%{arch}
install -p -m755 -D %{SOURCE1} $RPM_BUILD_ROOT%{_bindir}/fltk-config
%endif

Obviously this has been in place for a VERY long time but the only use case I can think of is to have fltk-devel installed from two different arches, i686 and x86_64 for instance.

Could this have anything to do with the systemd-nspawn change? Could it have caused `uname -i` to no longer resolve correctly?

Does this really need to be supported at this point?

Thanks,

Richard
