General (but related to Code::Blocks) / Re: C::B reports wxRecursionGuards error when loading a cbp project
« Last post by ollydbg on Today at 04:39:37 am »
I lot of tools help me to find the crash/assert.

1, gd_on's unified code::blocks cbp/workspace files(gerard-durand/codeblocks_gd_cbps: Workspace and projets files to build Code::Blocks for Windows as a wxWidgets version independant), I can simply change the option so it links to the debug version of the wx 3.3.1, just change a global compiler variable wxWidgets.WX_SUFFIX from "u" to "ud". Without this unifiled cbp, I think I need a lot of changes.

2, gdb(I'm currently using ssbssa/gdb: Unofficial Windows build of gdb with added features., I think other gdbs are all good)can catch such crash call stack.

Thanks for the report.

Maybe, he could change his email address and register again.

If that still failed, I think I will wrote an email to our web admin to check whether the email system works or not.

Note the email notification(our the forum thread) works OK.

@ ollydbg

Thank you for that traceback. It spots the errror.
I can be so dumb sometimes. I remember that I copied that code from the original testing "prob of LSP" and told my self I'd need to revisit later. Then I forgot.


I'll fix it to use cross thread communication.

Another issue is the payload.

Code
e.SetPayload<std::string*>(&stdstr);
m_notifiedWindow->ProcessEvent(e);

We can not pass the local variable's address from the worker thread to the GUI thread, we should bring the whole std::string instead.

When I looked at the #6 of the call stack, I see this:

Code
                            if(!buffErr.IsEmpty() && m_notifiedWindow) {
                                // we got some data, send event to parent
                                //clProcessEvent e(wxEVT_ASYNC_PROCESS_STDERR);
                                wxThreadEvent e(wxEVT_ASYNC_PROCESS_STDERR, wxID_NONE);
                                //wxString& b = const_cast<wxString&>(e.GetOutput());
                                //b.swap(buffErr);
                                //e.SetProcess(m_process);
                                //m_notifiedWindow->AddPendingEvent(e);
                                //-std::string stdstr = buffErr.ToStdString(); loses data
                                #if wxCHECK_VERSION(3,1,5)
                                std::string stdstr = buff.utf8_string();
                                #else
                                std::string stdstr =  buff.ToStdString(wxConvUTF8);
                                #endif
                                e.SetPayload<std::string*>(&stdstr);
                                m_notifiedWindow->ProcessEvent(e);
                            }

It shows this statement: m_notifiedWindow->ProcessEvent(e);

So, this is a working thread, is it possible to call the ProcessEvent event from the working thread? I think it should be "PostEvent" or "QueueEvent". Am I correct?

So, it is inside the clangd_client code?

@ ollydbg
Did this backtrace come from click cancel/stop when the assert applied, or at some other time?

Sorry, it is about several months ago, I forget it.
In the recent assert message box, I don't see the call-stack again in the RPT file.
I will try to reproduce it again.

Help / c++23
« Last post by rlfrost@aol.com on February 21, 2026, 10:46:54 pm »
Guys/Ladies

I can't for the life of me set up a project for Code::Blocks for c++23.
Before the newest release, I was using Code::Blocks pretty exclusively, but I switched to KDevelop for c++23 support.
Now that Code::Blocks supports c++23, I would like to switch back.
I am using Clang, and creating a project via the built-in wizard, but even the most simple file will not compile.
I I use the default wizard project, compiling complains of no .pcm, and if I generate a .pcm from the command line.. you get the idea...
I am beginning to think that I am just too stupid to pull this off.

Thanks for any advice,

Larry
