I already tried it and my local installation is 2 days old. I pulled again the dev branch now and I also got another error (actually a while ago but I forgot to report it):

Commit d5263e gives me the following error:

/home/makoeppe/mu3e/midas/progs/mhdump.cxx:393:42: error: ‘ctime’ was not declared in this scope

After adding #include <ctime> it compiles fine.

However, after cleaning the ODB and setting up everything fresh I don't even have the pages on the left bar anymore.

Best,
