I am trying to build O2 on CentOS7 with aliBuild, via
aliBuild build O2 --defaults o2
after following all the prerequisites from the tutorial. The build fails at DebugGUI@v0.5.2 with the following log: log.txt (44.1 KB)
The error is at l.436: Package capstone was not found in the pkg-config search path.
although email@example.com was built indeed. Issues with tbb are raised as well: error: #error Intel(R) Threading Building Blocks 2018 is required; older versions are not supported.
I found several solutions for Ubuntu, but nothing for CentOS.
Any suggestion for fixing this?
I have no solution here, but rather a very similar problem on ubuntu 20.04.
In my case package capstone also couldn’t be found, so I installed it. Afterwards, I see lots of undefined references and DebugGUI fails to build
Here’s the log file: log.txt (198.6 KB)
I used exactly the same system (minus capstone) to build O2 on 29.04.
Just a side note: I patched the alidist recipe for DebugGUI. With that patch the build works for me without having to uninstall libtbb-dev on Ubuntu 20.04.
I have the feeling that the TBB=off flag is not correctly handled.
So the change is simply to add the flag -ltbb to make.
Not sure if this has side effect, since for me DebugGUI is unfortunately not working (LLVM Error in the TPC reconstruction workflow - #30 by oschmidt)
Patch: (.patch files cannot be uploaded) debuggui.txt (1.0 KB)
Somehow it seems more intuituve to me that the build fails if TBB is missing than if it fails when TBB is installed, but not correctly picked up by the build. For Ubuntu TBB is even listed as a prerequisite, so most of the people who use Ubuntu probably have it installed.
Should we remove libtbb-dev from the list of required packages for Ubuntu if it does not work when it is present?
Yes, I confirm that with that PR the build succeeds on Ubuntu 20.04 with libtbb-dev installed. Thank you very much! I just noticed that building DebugGUI takes a bit long. Can the build also be parallelized?
