Hello,
i try to install Root from source on Ubuntu 22.04 LTS,

I copy/paste the lines from

But when i write:

I don’t understand. Thanks for any help,

Hello,

Could you make sure you have installed all the ROOT dependencies? You can find a list here:

3

Hello, yes i did what is given here for ubuntu:

4

Hello,
Yes, i did the command given here:

5

Hello,

Then this should get you everything you need, any ideas @bellenot ?

6

@Frederic_Faure which version of gcc are you using?

EDIT: And BTW, instead of the content of CMakeFiles/CMakeError.log file, I would prefer to see the actual command line output when running cmake -DCMAKE_INSTALL_PREFIX=…/root_install …/root_src because most of the errors in CMakeFiles/CMakeError.log are expected (system/compatibility checks)

It looks like the issue is due to “^/home/faure/install/c++/root_src”. can you try in another directory, not containing special characters (i.e. without ++) and let me know?

Yes, thank you, i move the directory name from `/home/faure/install/c++/root_src to /home/faure/install/cpp/root_src and the command worked well. But there has been a new error for the second command (see below)

This first command gives:

========================================

By the way, I have a question please: i will need to use multi-threads programming later, and here the cmake command said:
“Threads disabled” . Can i change this as an option?

============================================
For the next step, since the command line: nproc gives: 8,
i continue with the next command:
cmake --build . – install -j8
After some while, i get:

I’m also having an error related to XROOTD, namely that the hash for v5.4.2 has seemingly changed.

-- SHA256 hash of
    /root/parts/root/build/builtins/xrootd/XROOTD-prefix/src/v5.4.2.tar.gz

-- Hash mismatch, removing...

Unsure as to why Github is serving a different file but either the upstream file will need changing back or the ROOT build scripts will need modifying to compensate.

(This is on the 6-26-02 tag, master doesn’t appear to have the same issue).

Edit: I can see this was patched for master a few hours ago

Since this effectively only impacts v6-26-00 and v6-26-02, the easiest temporary workaround is to just run git cherry-pick 8c22e4b9985246fa8ea39fdac0c33822c865c2c3, clean the cmake environment and try build again.

11

I confirm this has been fixed in the master branch and will be back-ported in v6-26-00-patches soon.

Hello,
Sorry, it is not clear for me.
Does it mean that it works now or not yet?
I re-tried the whole installation commands and after the command:
cmake --build . – install -j8

i still get the error:
[ 29%] Linking CXX static library …/libLLVMSupport.a

– TBB build command succeeded. See also /home/faure/install/cpp/root_build/TBB-prefix/src/TBB-stamp/TBB-build-.log

The error with XROOTD has been fixed (you have to update your source if you want to pick up the latest version). otherwise you can also disable xrootd

14

But i have updated the source by doing:

git clone --branch latest-stable --depth=1 https://github.com/root-project/root.git root_src

and still get the above error (last message). Is there another way to update?

15

Try with the head:

git clone https://github.com/root-project/root.git root_src
16

(the fix is not part of the latest-stable branch, only of the default master and the v6-26-00-patches branches)

Thanks very much,
By the way, I have a question please: i will need to use multi-threads programming later, and here the cmake command said:
“Threads disabled” . Do i need to change this, is it an option?

18

For multi-threading with ROOT,
you have imt and builtin_tbb enabled, so you are good for multi-threading. I don’t know what Threads disabled is about, maybe @bellenot does.

Cheers,
Enrico

This message is irrelevant. As @eguiraud said, if you use -Dbuiltin_tbb=ON and -Dimt=ON, then it should be OK

Thanks a lot.
