Tumbleweed x86_64 64-bit architecture only possible?
Hello, I found x86_64 gcc13 requires glibc-32bit and glibc-devel-32bit, which are imported from i586 arch, to build. May I ask is it possible to have pure 64-bit x86_64 only Tumbleweed? If we still need i586 together with x86_64 arch in Tumbleweed to work, what is the differences between openSUSE:Factory i586 arch and openSUSE:Factory:LegacyX86 i586 arch, are they the same in most parts? Thank you. Best Regards

When you look at https://build.opensuse.org/project/show/openSUSE:Factory you notice on the right (under Build Results => standard) that x86_64 has 15962 packages built, but i586 only has 1572 - so just 10%. They might be the same as LegacyX86, but they are not enough for a working distribution. https://build.opensuse.org/project/show/openSUSE:Factory:LegacyX86 OTOH has 14952 - including Firefox and Thunderbird Ciao Bernhard M.

$ rpm -q gcc13 --requires |grep glibc glibc-devel
Just to illustrate, my vm is "pure" 64bit while having: # rpm -q gcc13 gcc13-13.2.1+git8205-1.1.x86_64 # rpmqpack |grep 32bit <nothing>

Hello, Thanks for everyone. https://build.opensuse.org/package/view_file/openSUSE:Factory/gcc13/gcc13.sp... at line 225: ------------------------------------ Name: gcc13 BuildRequires: xz .... BuildRequires: glibc-devel-32bit .... ------------------------------------ It needs glibc-devel-32bit for build gcc13. And then look at here: https://build.opensuse.org/projects/openSUSE:Factory/packages/glibc:i686/rep... "glibc-devel-32bit" is imported from i586. Is it possible to build gcc with out "glibc-devel-32bit"? Or without importing from i586, how can man build "glibc-devel-32bit" on x86_64? Thank you.

it's possible to drop that from the specfile, along with the --cpu-32= option (or whatever it was called) that's used in the %configure call. Just put the work into it.

Does it mean the compiler will not be able to produce 32 bit binaries anymore?

Without glibc-devel, the build cannot produce some component libraries (I guess libobjc.so.4), which means you could compile ObjC sources, but not produce a final ObjC program unless you find a suitable libobjc (replacement) somewhere. Ideally, cross-i386-gcc13 will address your concern. (The build just isn't enabled currently. Strange...)

You can also simply define 'disable_32bit' in the project config (or at the start of gcc13.spec).

Yes. GCC can't build 32bit target libraries without 32bit glibc. But the compiler can still produce 32bit assembly with -m32, just almost every link it emits will fail. Richard.
