I suspect this doesn’t need LD_LIBRARY_PATHto be set at all though. The PYTHON=python3setting is only necessary for RHEL-8 and above — EPICS builds only need python when you set LINKER_USE_RPATH=ORIGIN. I am planning to replace the Python script with Perl though (thanks Argo!).

fyi. an example recipe from an old RPM build.

Last I checked, even with ORIGIN, the LD_LIBRARY_PATH needs to be set during a build.
And it should not cause problems if it isn't necessary.


The epicsdeb builds do the same, but parts of that process are hidden away in some perl
scripts, and so are harder to follow ;)
