Debug the IDE

I am trying to understand better the Lazarus IDE project (and possibly
make some patches).
However, when I open Lazarus.lpi project, I can't compile it and debug
it inside the IDE. The following message pops up:
QuoteThe project's compiler options has no compile command.
See Project / Compiler Options ... / Compilation

I can't find "Project / Compiler Options ... / Compilation". I looked
into "Project/Project Options.../Compiler Options/Compilation and
Linking", but I cannot find what is not set there - everything looks
same as in my personal projects.

Can you help me?

I tried to debug the latest trunk version of Lazarus.lpi (rev. 48093).
I tried with trunk version itself, and I tried to open it with 1.4RC3.

You can compile it using "Build Lazarus ... " from tool menu. Use
"configure build ..." to add options such as
-gh -g -gw -godwarfsets   -Criot -gtt -O-


After that, you can press F9 to start it in the debugger.

On" checkboxes.

Lazarus cannot be built as a normal project yet. It will change some
day.

Indeed debugging with lazarus.lpi may not be documented anywhere. I
remember asking the same questions years ago.
Maybe Zoran adds it to wiki somewhere now that he knows how to do it.

Thank you, all!
