Plugins development / Re: Debugger_gdbmi plugin

« Last post by Pecan on May 05, 2026, 06:38:14 pm »

@ gd_on and ollydbg

acknowledge; watches problems put on top of the ToDo list.

also, I'll remove the gdbinit file from the github repo. It should not be there.

debugger_gdbmi tries to create the file dynamically if it finds gdbinit missing and it can find a valid wxWidgets installation folder which contains print.py.
If it finds gdbini already created, it leave it as is, assuming that the user created it themselves.

ollydbg's description of activated multiple debuggers is correct.

Last question : can we have both plugins (standard and gdmi) activated ? Or is it better to have only one activated (as for codecompletion and clangd_client) ?

Yes, you can have both of the 2 debugger plugins enabled. There is a menu item: Debug->Active debuggers->You can select one.

- with standard debugger, when I open the watches window, all my local variables are displayed. With gdbmi, I have to add one by one an explicit Watch to my local variables. I can then follow the content of my variables step by step when executing.

In the standard debugger plugin, this is the option: "Watch local variables". In the gdbmi plugin, I also see this option is ON, but I see the same issue here, which means local variables were not listed in the watches panel.

That "std=c++23" is suppose to be  "-std=c++23" (note the dash)

A few remarks on debugger_gdmi plugin.
I have created a debugger_gdmi folder Inside plugins\contrib and put inside a copy of your git repos.
I have added 3 lines in my CodeBlocks_Windows.workspace as it is for all other plugins.

Code

	<Project filename="plugins/contrib/debugger_gdmi/debugger_gdbmi_Windows.cbp">
		<Depends filename="CodeBlocks_Windows.cbp" />
	</Project>

Building C::B as usual, produces as previously my C::B version, but containing this time debugger_gdmi.zip and debugger_gdmi.dll at the correct place.

My first debug tries did not work as expected.
I find in your distribution a gdbinit file. It contains a path to print.py, but it does not match a path on my system. I tried to replace this path by the one I have (for example C:\wxWidgets-3.3.2\misc\gdb), but it does not seem to change something. Is this gdbinit file useful ?

Finally, I made it work by avoiding space and/or accentuated characters within the path to my executable. The standard debugger.dll (which uses the same gdb.exe) seems to be more tolerant with that.

Other points to notice :
- with standard debugger, when I open the watches window, all my local variables are displayed. With gdbmi, I have to add one by one an explicit Watch to my local variables. I can then follow the content of my variables step by step when executing.
- at the end of my program, if I try to restart it, while the watches window is still opened, I see my variables, but their content is not updated: 2 solutions here, open new watches on the same variables and I see that only the new ones are updated, or simply rename them but without really changing the name (just clic on return at the end of the variable name).

Last question : can we have both plugins (standard and gdmi) activated ? Or is it better to have only one activated (as for codecompletion and clangd_client) ?

Executing codeblocks.exe /d /p CBdevel in output33_64 displayed a message saying wxmsw332u_gcc_custom.dll couldn't be found and reinstalling it might fix the problem. Is there something that I can substitute for it?

go to your ...\wxWidgets332\lib\gcc_dll\ and copy those dll(s) into output33_64.
go to your compiler bin directory (the one you used to compile CodeBlocks) and copy these files to output33_64:
libgcc_s_seh-1.dll
libstdc++-6.dll
libwinpthread-1.dll

Thanks for the detailed response. I'll give it a try tomorrow. I was under the impression that debugger_gdbmi needed to be built from a compiled version of C::B
