CMake warning about UpdateGitInfo

Dear Root Experts,

Is the following warning during ROOT installation a problem?
The installation is source build.

CMake Warning at /opt/keksoft/ana/root/root-6.30.02/cmake/modules/UpdateGitInfo.cmake:45 (message):
Cannot determine git revision info: source is not a release and not a git
repo. Noting v6-30-02 as commit.
Call Stack (most recent call first):
/opt/keksoft/ana/root/root-6.30.02/cmake/modules/UpdateGitInfo.cmake:50 (UPDATE_GIT_VERSION)

The installation continues and ROOT then works.

Best regards,

_ROOT Version: 6.30/02
_Platform: AlmaLinux release 8.9
_Compiler: GCC 8.5.0 20210514

Dear Ohshita,

Not necessarily. Did you try to clone from the GitHub repo, configure and build? The warning is not there, we do not see it in our CI for example.


Dear Danilo,

Thank you for your quick reply.
I got the ROOT source file as a tar.gz file from the download site.

As your mention, when I tried installing with the clone from the GitHub repo,
I also make sure no-warning.

Best regards,

Thanks for taking the time to report back!
