Was the possibility of creating a make uninstall script to complement cmake’s make install which would delete all the files listed in install_manifest.txt ever considered? If so, is there any inherent reason why the idea was discarded? One of the problems could be the removal of files that were ins…

[image] Missing Canvas ROOT Honestly speaking, sooner or later, you will learn by hard that the policy of using a “system-provided” ROOT version (e.g. in “/usr/[bin|lib]” or “/usr/local/[bin|lib]”) is a dead end. You will learn that you need something like three different…

I support this feature. From what I understand cmake does not allow natively to do “make uninstall” but for this sure, such feature would be really useful. I think you should open a JIRA ticket to track this feature request.

As discussed in the pull request, I think that adding make uninstall is not a good idea. If you install a custom ROOT compiled by hand, just install into a custom directory like /opt/root-6.16 or similar, which you can just remove later to uninstall. With make uninstall it’s too easy to break things…

@Wile_E_Coyote I think that what you say in your linked post is no longer true. It’s perfectly possible now to use, for example, Fedora, and use ROOT that you get with yum install root. It’s usually the latest version or close to latest, and incompatibilities are not such a big issue anymore. You ma…

If we installed ROOT in /opt/root, there is indeed no interest to use “make install”. The advantage of “make uninstall” is clear when we did not specify any install prefix and then ROOT has been installed in /usr/local. If it breaks something on Mac OS, maybe some “workaround” exists (I do not kno…

Sourcing more than one thisroot.sh in the same shell, MUST NOT mess up the environment. This script IS EXPECTED to clean any environment variables which reference the “previous” version and then add appropriate entries for the “new” version.

[image] pamputt: If we compiled ROOT and installed it in /usr/local, what is the solution to properly uninstall it in order to avoid version mix? If you installed more than one compiled ROOT into /usr/local they will have partially overwritten each other’s files. There’s not much that can be …

I believe that is indeed what happens ( @amadio correct me if I’m wrong) . I never had problems sourcing more than one thisroot.sh in the same shell. Building ROOT with an active thisroot.sh, however, can be tricky.
