aliBuild fails at ninja on ubuntu 18.04

O²
1

Dear Experts,

I am trying to build O2 on Ubuntu 18.04 LTS.

I already had the O2 built on my laptop a few months ago and now when I am trying to build it again using aliBuild build O2 --defaults o2 command then it is giving an error at the time of building ninja
The log file /home/vivek/alice/sw/BUILD/ninja-latest/log turns out to be empty. I see exactly the same error when I am trying to build the QualityControl using the command aliBuild build QualityControl --defaults o2 -d. The last few lines of terminal-log when build using the debug mode is pasted below and the full log can be found at https://cernbox.cern.ch/index.php/s/6DYL1Fkt9ZomrgK

I am not able to understand what is going wrong, can someone let me know how do I fix it?

Thanks in advance.

Hello @vksingh

did you try to cd alidist; git pull --rebase and build everything again?
I’m not expert but I found for myself (ubuntu 20.04) that updating alidist helps in many unclear cases.
Also you have pretty old installation so I expect that building from the scratch will take similar amount of time as re-building existing installation. So my second suggestion is to remove everything and start with aliBuild init …

Best regards,
Sergey

Hello @sevdokim

Yes, I tried updating my alidist and my git version but I was facing the same issue. Now I have freshly built all the required packages.

Thanks and regards,
Vivek

Hi @vksingh, could you try removing /home/vivek/alice/sw/SOURCES/ninja/fortran-v1.8.2.g3b/v1.8.2.g3bbbe.kitware.dyndep-1.jobserver-1 (e.g. using rm -rf)? I suspect it somehow ended up as an empty directory, which confuses aliBuild.
