Module 'stl' imported by AST file found in a different module map file

I compiled ROOT 6.16 with the following cmake command

cmake -Dcxx14=ON -Druntime_cxxmodules=ON -Dminuit2=ON -DCMAKE_INSTALL_PREFIX=/opt/root6.16 -Dpython=ON -DPYTHON_EXECUTABLE=/usr/bin/python3.5 -Droot7=OFF …

The compilation ended successfully.

Yet, when I start “root”, I get this following error messages

root

@yukatkh can you take a look please? :slight_smile:

Hello, thank you for the report. Did you source thisroot.sh from (/home/pamputt/root-6.16.00/builddir/bin/thisroot.sh) ? This is an error when ROOT finds multiple modulemaps in your paths.

Actually this is weird. If I source thisroot.sh from /home/pamputt/root-6.16.00/builddir/bin/thisroot.sh, ROOT starts successfully. But if I source from /opt/root6.16/bin/thisroot.sh, I get this crash. The thisroot.sh file is exactly the same.

You built ROOT in /home/pamputt/root-6.16.00/builddir/ and installed to /opt/root6.16, right? The problem was that module has a hardcoded path to build directory even if it’s installed. This is already fixed in master, and will be backported in 6.16.02. Meanwhile, could you please use ROOT from bulid directory when using runtime modules? Sorry for inconvinience, but I’m happy that someone is trying this feature out.

Yes, that’s it. So I will source from the build directory. Thanks for the explanation.

I checked on the github repository and I do not see which commit fixes this issue.


This one should fix your problem, it’ll be great if you could try it out!

Ok, I will try these changes and let you know. BTW, this code is not yet present in the 6.16 branch.

I just downloaded the latest version of the 6.16 branch (where the patch has been backported) and compiled it successfully. The problem is fixed.
