  • 1.  python3 3.7.9 symlinks in /usr/bin are missing

    Posted 09/17/20 06:44 AM
    Hi,

    python3 3.7.6 had symlinks in /usr/bin:

    # rpm -q python3
    python3-3.7.6-1.ppc
    # ls -l /usr/bin/python3*
    lrwxrwxrwx 1 root system 30 Sep 17 12:41 /usr/bin/python3 -> ../../opt/freeware/bin/python3
    lrwxrwxrwx 1 root system 32 Sep 17 12:41 /usr/bin/python3.7 -> ../../opt/freeware/bin/python3.7
    lrwxrwxrwx 1 root system 35 Sep 17 12:41 /usr/bin/python3.7_32 -> ../../opt/freeware/bin/python3.7_32
    lrwxrwxrwx 1 root system 35 Sep 17 12:41 /usr/bin/python3.7_64 -> ../../opt/freeware/bin/python3.7_64
    lrwxrwxrwx 1 root system 33 Sep 17 12:41 /usr/bin/python3.7m -> ../../opt/freeware/bin/python3.7m
    lrwxrwxrwx 1 root system 36 Sep 17 12:41 /usr/bin/python3.7m_32 -> ../../opt/freeware/bin/python3.7m_32
    lrwxrwxrwx 1 root system 36 Sep 17 12:41 /usr/bin/python3.7m_64 -> ../../opt/freeware/bin/python3.7m_64
    lrwxrwxrwx 1 root system 33 Sep 17 12:41 /usr/bin/python3_32 -> ../../opt/freeware/bin/python3_32
    lrwxrwxrwx 1 root system 33 Sep 17 12:41 /usr/bin/python3_64 -> ../../opt/freeware/bin/python3_64

    Hi Andrey,

    Yes we are no more going to provide symlinks in /usr for packages from AIX toolbox.
    This cause issues with the base AIX binaries, libraries and include files.
    Going forwards we are going to start removing symlinks from /usr for all packages and request everyone to use /opt path.
    This is going to be some inconvenience initially but it is good for long run.

    I have the same issue and IBM Spectrum Scale DM' smmsysmoncontrol command is looking for it in /usr/bin.

        mmsysmoncontrol restart

         Fri Dec  2 13:37:00 EST 2022: [W] Python >= 3.6 not found in /usr/bin/python3. The Spectrum Scale monitoring service will not be started.

    Any suggestions?

    Hi Carl,

    Though their policy has changed about putting symlinks in, there's no reason you can't do it if you need them. Try setting your PATH first, then resort to links.

    Thanks Mario. Thats right. If user wants to create symlink in their environment they can still create.
    From AIX toolbox we will not do as we are not aware of environment and blindly polluting /usr can result in other issues (we have seen that in past)
