This seems a reasonable default to me. > I had not given this topic any consideration before you raised it and I am now > wondering why I need tools installed with symbols. The only case I can think of is eg. debugging a GCC crash. I've have GCC crash on me occasionally, thus far it has been due to some (reasonably obvious) bad input on my part. FYI. I have uploaded a build of 5.1 of i386/pc686 for use on travis-ci.org (and potentially others) https://github.com/mdavidsaver/rsb/releases/tag/20200829 > curl -L > "https://github.com/mdavidsaver/rsb/releases/download/20200829/i386-rtems5-bionic-20200829-5.tar.bz2" > | sudo tar -C / -xmj This will unpack as /home/travis/.rtems/ _______________________________________________ users mailing list users@rtems.org http://lists.rtems.org/mailman/listinfo/users
