Ferenc Gerlits updated MINIFICPP-1471:
--------------------------------------
Description:
Extensions (processors, controller services, and utilities used by them) are
currently built as static libraries, and are linked into the minifi executable.
We need to change them to separate shared library plugins which we can load at
runtime.
Development of these tasks should be done on a separate branch (TODO: add
branch name), as there will be many conflicts with other changes. Merge the
main branch to the development branch from time to time, in order to reduce the
amount of pain we'll have when merging back to main at the end.
Notes:
* We need to make sure the plugin we are trying to load is compatible with the
minifi core (and not load it if it isn't). Initially, we can require a build
version string to match, ie. each plugin will need to be recompiled for each
minifi release. We can improve on this approach later.
* Later we may want to add support for unloading/updating plugins, but this
doesn't need to be part of the initial rollout.
