Building ROOT 6.24 (the v6-24-00-patches branch)

ROOT

Oh, sorry, I just noticed there it says -- Detected ROOT_VERSION 6.29.01 but I cloned the repo you sent :confused:

9

I tried again and it keeps saying that the detected ROOT version is 6.29…

10

git clone --depth 1 --branch v6-24-00-patches https://github.com/root-project/root.git v6-24-00-patches

11

Ok thank you so much! It generated successfully. The problem now is that compilation breaks at this point:

[  0%] Performing configure step for 'XROOTD'
-- XROOTD configure command succeeded.  See also /Users/diiego/software/ROOT/ROOT_6.24/build/XROOTD-prefix/src/XROOTD-stamp/XROOTD-configure-*.log

And I cannot understand why gmake is not working

Try to add -Dxrootd=OFF when configuring ROOT (switches the support for XRootD off).
Note: you need to remove the old build and configure it from scratch again.

13

Ok great, now the compilation is working. I will let you know if something else goes wrong. Thank you so much again :grinning:

14

You could try: -Dall=ON -Dxrootd=OFF

15

Hello again,

I tried with both option, only -Dxrootd=OFF and both -Dall=ON -Dxrootd=OFF, and the compilation always fails here:

Any clue about what may be happening? I guess it has to be with PyROOT, but do not know what.

Thanks again

I’m afraid you face “cppyy3_11” problems, e.g., something like:

@bellenot @etejedor Could someone backport the required fixes to “v6-24-00-patches” (the last version which supports “-std=c++11”)?

17
18

So… Does this have a solution? I’m a bit lost at this point to be honest.

19

Wait until the relevant changes are committed in the v6-24-00-patches branch

20

@bellenot Was this the only fix needed for “cppyy3_11”? Here (see above) it actually complained about “expression is not assignable”, not about a missing “code.h”.

21

@Wile_E_Coyote Oh, ok, sorry. Then I’ll have to investigate next week. And FYI, I’m not a PyROOT expert (not even a user)

22

So, we may need some python experts … @Axel @vpadulan

24

Working on it

25

Thanks!

26

So hopefully the PR #12514 should fix it. I’ll let you know once it’s merged
EDIT: I’m looking for all required changes for Python 3.11, and it will take more efforts and time than expected… Stay tuned!

27

Ok, thanks a lot again!

28

OK, the PR failed. So we will need a Python expert here, once one is available…
