MacOSX: CB crashes at Settings/Compiler and debugger

[afb]

Adding a resource fork (with: `wx-config --rezflags` /path/to/bin/codeblocks) is enough to make wxMac receive events and not launch in the background, and useful when debugging.

[bnilsson]

Please clarify.
Is this something you do in configure or just on the fly?

Just go to the terminal and run `wx-config --rezflags` /path/to/bin/codeblocks
This one of the ways to be able to receive events in wxWidgets apps.

[bnilsson]

I tried it and it had no effect.

[afb]

You should also be able to start your bundle up like so:

Code Select Expand

(gdb) run --prefix=/Users/bnilsson

[bnilsson]

Thanks, I can start it but it does not respond to clicks.

So, finally, I got a backtrace for the Settings/Compiler and debugger crash. (I didn't pay attention to the singlequotes in `wx-config --rezflags` before)

Could you compile CB with the debugging option -g on?
That backtrace has no symbol tables.

or try this:

Try the following in your working copy:

Code Select Expand


make clean-zipfiles // <- this is the important part
make
make install // (or whatever it is that you do on Mac)


(don't type the comments!)

[bnilsson]

mandrav just fixed it all (at least for me) by:

     make clean-zipfiles

It fixed both the "Settings/Compiler and debugger" and "Project/Build options" crashes.

[bnilsson]

BTW: show me the command line that enables a compile with the debugging option -g.
Is it a configure option?

g++ -g your_source_file.cpp


[bnilsson]

Would I have to change to "g++ -g" in every Makefile?
It seems like a lot of work and to invite mistakes.
Is there a more semi-automatic way to setup the CB build to use this option?

[bnilsson]

I was asking how to build CB with the debug option on, not how to use it.
I have not yet been able to build CB using CB.

[afb]

Strange, I instead find that I need to strip my binaries of debugging symbols afterwards ?
(i.e. that it does build with the -g symbols enabled by default, and is huge because of it)

But they might be talking about the extra Code::Blocks debug code, enabled by configure:

Code Select Expand

  --enable-debug          turn on debugging (default is OFF)
