Building LMMS in order to produce useful bugreports

Hi,

I’m used to build LMMS. Did it on Debian Sid for many years, but now I just had a new PC, which I installed on Debian 12. I’d like to keep on this stable release (at least trying to do so until I feel the urge to go back to Sid for any reason ^^).

LMMS builds, which is nice. The problem I noticed are:

- the color picker is very basic. I had another, much better, with the possibility to pick a color from screen. (not very annoying though I guess I miss some optional Qt5 libraries maybe.
- on any effect plugin I use, both the decay and gate knobs are greyed. Never had this behavior when building on Sid.

Ma question is: is it desirable to activate the following option in the CMakeList.txt:

OPTION(WANT_DEBUG_FPE "Debug floating point exceptions" ON)

Is ii useful I report some bug with this option enabled? I have 2 ou 3 cases of segfault where at least one is easily reproductible.

Is there any other option I could use to produce potentially useful bug reports?

Yeah!

I found the solution for the greyed knobs. I guess I didn’t have this problem on my last computer because the settings remain between new builds (~/.lmms/…):

In Edit->Settings there's an option labeled "Keep effects running even without input". Turn that off and those knobs will function.
