Because your LCL is probably build with STABS. And gdb can read stabs, 
but FpDebug can't.

The problem is -g => and that is also the reason for the "Chose DWARF" 
dialog that pops up when you haven't explicitly set your project to dwarf.


-g is decided by FPC, it can be stabs or dwarf. Depends on Target and 
fpc version. The IDE does not have a list, so (prior to compiling it 
does not know). Therefore when using FpDebug the IDE requires explicit 
set to Dwarf. (But only checks the project).

Ideally the IDE should have a setting "Use IDE default" or "Follow 
project" for packages. But you can't put that in Makefiles (which are 
still used), because it would need to be translated before handing it to 
fpc.
Still, if we accept that any "just installed" or "build with make" files 
get immediately rebuild by the IDE, then it could be added.... But it 
hasn't yet (and probably is major work)

Yes, it's either, or, or both.

Additions and Overrides (with *) will affect ALL packages, even 3rd 
party. As long as they are part of the project (except RTL, because the 
IDE does not rebuild RTL / or fpc packages dir).

"Configure build Lazarus" only affects (most) packages that came with 
Lazarus. => they have $(IDEBuildOptions) in their "custom options".
But once done, it is done for all projects (for the packages that follow 
it).
