Hello,
the latest INDI update doesn't compile on Leap 15.{4,5} due to:


[   48s] In file included from
/home/abuild/rpmbuild/BUILD/indi-2.0.1/indiserver/indiserver.cpp:97:

updating libev to the latest version (4.33, which is from 2020) fixed the
issue.

According to the release notes, there is one incompatible change though:

* 4.25 Fri Dec 21 07:49:20 CET 2018
  - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
    (EV_THROW still provided) and now uses noexcept on C++11 or newer.
