Building O2 fails at Monitoring on Ubuntu 18.04

O²

Hi,

I am trying to update O2 on my local laptop (Ubuntu 18.04) for QC development and I get a crash when building O2 at Monitoring:

Here is the full log file: CERNBox

Alidist-master, O2-dev, QC-master are all updated to latest version.

Any hint for solution would be appreciated.

Thanks.
Cheers,

Hi,

I was able to make the O2 compile by manually editing “gcc-toolchain.sh” in alidist. The required change was to delete the line allowing the gcc-toolchain version 70300

  case $REQUESTED_VERSION in
    v10*) MIN_GCC_VERSION=100200 ;;
    *) MIN_GCC_VERSION=70300 ;;
  esac

to

  case $REQUESTED_VERSION in
    v10*) MIN_GCC_VERSION=100200 ;;
  esac

Then both O2 and QC compiled without errors. I remember seeing a problem with gcc version in other threads, not sure if this is connected.
