Bug 795582 – =sys-libs/glibc-2.33-r1 causes /lib64/ld-lsb-x86-64.so.3 collision with cross-* packages

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Sergei Trofimovich (RETIRED) 2021-06-12 11:13:20 UTC]

=sys-libs/glibc-2.33-r1 regressed at handling ROOT=/.

I have a `crossdev -t x86_64-HEAD-linux-gnu` target installed. Today glibc failed to install with a collision with sys-libs/glibc:

 * checking 1404 files for package collisions
 * This package will overwrite one or more files that may belong to other
 * packages (see list below). You can use a command such as `portageq
 * owners / <filename>` to identify the installed package that owns a
 * file. If portageq reports that only one package owns a file then do
 * NOT file a bug report. A bug report is only useful if it identifies at
 * least two or more packages that are known to install the same file(s).
 * If a collision occurs and you can not explain where the file came from
 * then you should simply ignore the collision since there is not enough
 * information to determine if a real problem exists. Please do NOT file
 * a bug report at https://bugs.gentoo.org/ unless you report exactly
 * which two packages install the same file(s). See
 * https://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how
 * to solve the problem. And once again, please do NOT file a bug report
 * unless you have completely understood the above message.

I think it's gentoo's own code that fails to account for $(alt_prefix):

        local lsb_ldso_name native_ldso_name lsb_ldso_abi
        local lsb_ldso_abi_list=(
                # x86
                amd64   ld-linux-x86-64.so.2    ld-lsb-x86-64.so.3
        )
        for (( i = 0; i < ${#lsb_ldso_abi_list[@]}; i += 3 )) ; do
                lsb_ldso_abi=${lsb_ldso_abi_list[i]}
                native_ldso_name=${lsb_ldso_abi_list[i+1]}
                lsb_ldso_name=${lsb_ldso_abi_list[i+2]}
                has ${lsb_ldso_abi} $(get_install_abis) || continue

                if [[ ! -L ${ED}/$(get_abi_LIBDIR ${lsb_ldso_abi})/${lsb_ldso_name} && ! -e ${ED}/$(get_abi_LIBDIR ${lsb_ldso_abi})/${lsb_ldso_name} ]] ; then
                        dosym ${native_ldso_name} "/$(get_abi_LIBDIR ${lsb_ldso_abi})/${lsb_ldso_name}"
                fi
        done
