Using alternative build systems (meson) for IOCs/modules

[Érico Nogueira Rolim via Tech-talk <tech-talk at aps.anl.gov>]

Hi!


I'm currently considering how to unify building an IOC [1] and one of
its dependencies [2], which uses Meson. I am struggling somewhat to come
up with a proper directory structure and rules to make that happen, but
it occurred to me that this would be much simpler if IOCs were built
with Meson instead of Make.

There is a PR to PVXS to enable building it with Meson instead of the
EPICS build system [3]. It depends on a change to epics-base that hasn't
been merged yet, and I don't know what its status in PVXS is. Is it
simply waiting for the changes to epics-base, or are there outstanding
issues and/or objections to the proposal?

Were that to be merged, would a possible future direction be to support
a Meson-based template for IOCs (and possibly modules)? It might help
simplify a lot of workflows and decrease the burden of debugging the
build system, since meson allows customization in a more standardized way.


Cheers,

Érico
