[HTCondor-users] container-based build of condor tag v23.3.0 on RHEL8

[Benoit Roland <benoit.roland@xxxxxxx>]

    Dear all,
    
    I am trying to build condor tag v23.3.0 on a RHEL8 machine using the
    approach described here [1].
    
    I am running in interactive mode:
    
    docker run --rm=true --user condor -t -i
    htcondor/nmi-build:x86_64_AlmaLinux8-23030008 /bin/bash
    
    cd /tmp
    git clone -b devel_v23.3.0
    https://github.com/benoitroland/C4P-HTCondor.git
    
    cd C4P-HTCondor
    mkdir __build
    cd __build
    cmake ..
    make -j 8 install
    
    where the branch devel_v23.3.0 of C4P-HTCondor is build from the
    condor tag v23.3.0 (git checkout tags/v23.3.0 -b devel_v23.3.0).
    
    A 20% of the build process, I got the error [2] associated with
    command_strings.cpp.
    
    Maybe I am doing some basic error...
    
    Did some of you have some time to reproduce this on the RHEL8
    machine?
    
    Otherwise, I would like to ask you; which tag or branch should I use
    to have a successful build?
    [preferentially a tag or branch as close as possible to the latest
    development, but not the main, because the container-based build is
    failing there as well]
    
    Thanks a lot in advance for your help!
    
    Cheers,
    ben
