What is requiring root access here? The point of line 585 is that 'make install' will install everything into its own directory. I just ran the script on Ubuntu 22 and there were no root requirements.

When running this in a fresh system with a regular unprivileged user, it tries to install udev rules and modifying ld.so.cache.

Here, this first example is from the Github Action runner:

make[1]: Leaving directory '/home/runner/work/EPICS-synApps-assemble/EPICS-synApps-assemble/synapps/support/measComp-R4-2/libuldaq-1.2.1'
/usr/bin/install: cannot create regular file '/lib/udev/rules.d/50-uldaq.rules': Permission denied
make[2]: *** [Makefile:484: install-dist_rulesdataDATA] Error 1
make[1]: *** [Makefile:814: install-am] Error 2
make: *** [Makefile:511: install-recursive] Error 1

This happens after the permissions to udev are fixed:

make[2]: Leaving directory '/epics/synapps/support/measComp-R4-2/libuldaq-1.2.1/examples'
make[2]: Entering directory '/epics/synapps/support/measComp-R4-2/libuldaq-1.2.1'
make[2]: Leaving directory '/epics/synapps/support/measComp-R4-2/libuldaq-1.2.1'
make[1]: Leaving directory '/epics/synapps/support/measComp-R4-2/libuldaq-1.2.1'

make: *** [Makefile:511: install-recursive] Error 1

To be sure, I removed sudo in my main branch and let it build as Github Action, the logs should be accessible for this job: https://github.com/BAMresearch/EPICS-synApps-assemble/actions/runs/8023437425/job/21919899065
