Hi ,
I made some more careful tests and read about build/rebuild, it now makes more sense.
When i build, i get the warnings from the headers parsed in modified files only. That’s why the number seemed random, it actually is depending on the files i modified before building.
When i rebuild, i get the full list of warnings for each headers in all the project.
If the same header appears many times in the project, its list of warnings will be repeated as much.
So in short, it gives a warning for each rpc it encounters in the headers parsed during builing/rebuilding.
So if you modify only a file that does not include any “declaring-rpcs-header”, you will get no warnings (i did this on a dummy file).
If you modify a file containing somehow (through included headers) server rpcs declaration, i bet you will get the warning even on a simple build.
Hope it helps.
Cheers
