Building Samba ourselves

partouf opened this issue · comments

commented

The UB distro's don't have the right version of samba that I need, so we need to build it ourselves.

Work in progress here https://github.com/compiler-explorer/infra/blob/main/setup-smb.sh

Current issue:

  • the smbd service is not installed when manually building, I might have seen a --configure thing somewhere for it
  • need to test locally instead of invoking a packer builder everytime (and building samba takes forever)

Little stuck now, built everything and installed service, but it gives a timeout without any hint of a reason why

Have tested this locally. Service actually runs fine if you run smbd manually, just when you use systemctl it does something completely different, I'm confused.

If I run smbd manually:

$ sudo /usr/local/samba/sbin/smbd -d 999999 -F --no-process-group

And when I run systemctl smb start, it times out and then logging says:

$ sudo systemctl status smb.service
