Error building root at XROOTD


I am trying to build root from source on another machine.
When I use make, I actually have the following error :

CMake Error at XROOTD-stamp/XROOTD-download-Release.cmake:49 (message):
Command failed: 1

‘/cmake/cmake_3_24_0/install/bin/cmake’ ‘-Dmake=’ ‘-Dconfig=’ ‘-P’ /root/root_6_26_06/build/builtins/xrootd/XROOTD-prefix/src/XROOTD-stamp/XROOTD-download-Release-impl.cmake’

and it repeats for a total of 7 times until it stops to compile.

Have you already seen this issue ? Do you have an idea how I can fix it ?

Thank you !

I just noticed that this is a known issue with the release… I will try an older version then


Thank you for reporting, it indeed looks like the same problem. I will comment on the issue (it was believed to be fixed for 6.26/04 and master).

Hi @Korlek ,

as of yesterday the tip of the v6-26-00-patches branch should not have the hash mismatch problem.

Another workaround is to install xrootd separately (e.g. as a system package): the ROOT build should then pick the system installation instead of trying to build the built-in version.
