Proposal: skip debug builds of native packages

Proposal: skip debug builds of native packages

[Jan Kircher]

Following the suggestion of Khem Raj after my issue with systemd-systemctl-native (https://lists.yoctoproject.org/g/poky/message/13589), I propose to not build debug versions of *-native packages when DEBUG_BUILD is enabled. At least for our use-case, building debug versions of native packages is unnecessary. Please share your opinions.

Greetings,
Jan

If I enable DEBUG_BUILD for a recipe, target or native, I expect it to be 
built with debug information. So the proposed change is definitely not one 
I would like to see.

If you are setting DEBUG_BUILD globally rather than per recipe, then the 
solution for you to avoid enabling it for native recipes would be to 
instead use:

DEBUG_BUILD:class-target = "1"

Absolutely not. Just because you had one isolated build fail in
systemd doesn't mean we now need to switch it off across everything.

Anyone who does serious layer maintenance has to debug crashes and
mysterious behaviour in native executables, and this is required
functionality.

Question is if DEBUG_BUILD should extend to native packages, you can 
still debug crashes with defaults. DEBUG_BUILD lowers default optlevel
which means we are building the package with an option set that is not
commonly tested. This cost is understood for target packages, but do we
want the supporting tools to be built with these options ? I don't think 
so. It will slow them down too.

So having an option to turn DEBUG_BUILD propagation to non-target 
packages can in fact help the majority of use-cases where OE is used.

As Peter said, there's
DEBUG_BUILD:class-target = "1"

We should perhaps better document this, but I don't think there should
be special-case hidden magic otherwise.

That will improve things for sure

That is a way better solution. I didn't know this is possible. Thank you!
