How can I step into every line of source code available?
lazarus / 12-Debugger

----------------------------------------------------------------------

I don't care if the source code belongs to fpc, lazarus, a third-
party, or me.  I'd like to be able to step over it if want to, or step
into it if I want or need to.  This is a dev box so I don't really
care how fat any .exe is on it.

Win 7 x64, fpc 3.0.0 bootstrap, fpc 3.1.1 and lazarus 1.7 trunks
2015-12-19

I have a great script I got from the forums that gets the trunks from
svn and builds fpc and lazarus from source.  For good measure before I
run it I recursively delete the fpc, lazarus, and appdata/local
folders so there's no residue.  I've tried so many things good or bad,
but right now for fpc it boils down to:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i make all
OPT="-O1 -gl -g"
and for lazarus it's:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i make bigide
OPT="-O1 -gl -g".

From within the IDE I've tried compiling and installing every package
I can find like this:

And for an example, I'm trying to step into
TSQLQuery.FieldByName().AsString:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i TMainForm =
class(TForm)  Button1: TButton;  Query: TSQLQuery; ... procedure
TMainForm.Button1Click(Sender: TObject);var  vName: string;begin 
vName:=Query.FieldByName('Name').AsString;  ShowMessage(vName);end; 
I put the ShowMessage() there just to make sure vName isn't getting
optimized out, eliminating the need for the ...AsString line
altogether.  Alt+Up Arrow brings be to the code I'm interested in
stepping into, but for the life of me I can't figure out how to get
the debugger there.

Can anyone help me out with this?

for fpc I use (dwarf), some may not be needed
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i make.exe
all LINKSMART=1  CREATESMART=1  DEBUG=1 OPTIMIZE=0  OPT="-gl -gw
-godwarfsets -O-1"
Lazarus IDE I build from within.
"Tools" / "Configure build lazarus"
Options "-gl -gw -godwarfsets -O-1"

Also open package FCL (nearly all packages depend an it), and edit its
options:
"Package Options" / "Usage", in memo "Custom" add $(IDEBuildOptions)

"Usage" means: any package that uses (direct or inderect) this
package, gets those options.

Thanks a bunch.  I have this working consistently now.  I implemented
the changes you suggested with these tweaks:

- In the OPT= parameter I think you meant -O1.  This is what I'm
using.
- I'm using your basic make all for FPC and make bigide for Lazarus in
the script.

I also noticed that Lazarus found and used FPC source code in a
subfolder in my downloads folder.  I unzipped this just to look at it
and really meant to delete the folder.  Here I pointed it to the
correct folder:

I have no idea which of these changes made the IDE work like I wanted,
maybe several or all of them.

I hope this helps anyone who is trying to step through the code like
me.
