The 15 August 2011 build (7386) DEBUGGER BRANCH version is out.

[Oleg_Sam]

I create 2 patches for CB:

1. Add support Environment variable on the Debugger path settings on debugger branch.

2. Disable Pre/Post buld steps, when using external Makefile.
The  Pre/Post buld steps must be disable when using external Makefile because Makefile must be independent from CB environment, so all pre/post build steps must be inside in Makefile. Projects may be build on command line shell without CB environment...

All patches I testing on debugger branch svn 7444 on winxp sp3 and works fine.

Thanks.

Debugger path patch

[oBFusCATed]

Non-debugger patches, should be made against trunk and discussed on the trunks topics.
Here we are interested only in the debugger.

BTW: Why would you want to disable the pre/post build steps? They could be useful if you're using a makefile you can't control. And if you need to build with the makefile only you could do so, no one stops you.

I'm experiencing a crash on win7 sp1 with rev7387. That's how it happens:
1-Launch cb without any project loaded.
2-Double-click 'CodeBlocks.cbp' file on my local trunk folder.

There comes the crash. Is it specific to me or anyone else able to reproduce it?

Note: CB doesn't crash if I load cb by double-clicking on the project file.

Does it happen with the trunk version of the nightly?
What happens if you disabled the CC?

[scarphin]

Trunk also crashes. When I disable code-completion, both (trunk and debuggers branch) work. I can then enable cc plugin. Can u reproduce the crash or is it just me?

[oBFusCATed]

CC is known to be crashy in this revision, disable it and wait for the next nightly...

Hello
I use MinGw/GDB. I'm getting this issue while debugging:
When the GDB just execute this line of code:
  wxString *psty = (wxString*) NULL;
I put the mouse over 'psty' and a SIGSEGV is prompt:

Code

> whatis psty
type = wxString *
>>>>>>cb_gdb:
> output psty
(wxString *) 0x0>>>>>>cb_gdb:
> output /c psty->wx_str()[0]@psty->length()
The program being debugged was signaled while in a function called from GDB.
GDB has restored the context to what it was before the call.
To change this behavior use "set unwindonsignal off".
Evaluation of the expression containing the function
(wxString::wx_str() const) will be abandoned.
Program received signal SIGSEGV, Segmentation fault.

I'm also using the script I posted some days ago:
http://forums.codeblocks.org/index.php/topic,15050.msg101768.html#msg101768

Of course, the problems arise because psty is not pointing to a valid wxString object.
What I ask here and myself is: How can C:B be aware of this before trying to output this invalid var?

Regards

[oBFusCATed]

I guess we can check for NULL in before evaluating some scripts...
But I suggest to use python enabled gdb + pretty printers for wxwidgets (there are available for 2.9+). This is the better approach.

I just test on gdb (the gdb build myself with python support, you can find download links in this forum), the log is below, it seems there is no crash.

Code

> p psty
$1 = (wxString *) 0x0
>>>>>>cb_gdb:
> whatis psty
type = wxString *
>>>>>>cb_gdb:

The difference probably is that you're accessing a member, but Manalo is calling a function...
