gdb problem

[szurilo]

Hi!

Iam using GNU gdb 6.5. Most of the time my gdb crash and i have to kill it from terminal. I read through many thread and comments and i found the problem isnt in CB but gdb. What gdb version i should use to avoid these crashes?

On Windows the best you can do is using GDB version 6.6.

Sorry for not describing my system parameters. I use Linux Debian, with CB nightly 5045(by Jens), wxWidgets 2.8.7 and GBU gdb 6.5.
I tried other gdb versions without success.

Which debian suite do you use ?

I don't find gdb 6.5 in any of the standard releases (except from sid for i386hurd):

In etch/stable it should be 6.4.90 and in lennny/testing 6.7.1-2
I have sid/unstable and there aren't any problems (gdb 6.8 ).

I downloaded the 6.5 from http://ftp.gnu.org/gnu/gdb/
As far as i remember i used the 6.4.90 from etch/stable but that's also had this bug. Actually i tried a lot of version of gdb and i remember some was good but i am too tired and busy to pick a random version and try it again.
Now i am installing 6.8.

I installed gdb 6.8, nothing changed. Sometimes gdb freeze before i reach any of the breakpoint, sometimes works perfectly. I am really confused about this. Am i do something wrong? Pls, someone help. I can't debug.

I can't debug.

I'm not the Linux guru here, but what about quickly installing a working distribution (Ubuntu) and using C::B there? I installed Ubuntu and C::B in a VM within ~2-3 hours. So it can be done quite quickly and you can continue working.

What does the debugger's debug-log say ?

Check "Settings -> Compiler and debugger... -> Debugger settings -> Display debugger's log".

Have you tried to start "gdb" from command-line to run your project ?

well GDB 6.8-3 :-)

[MortenMacFly]

well GDB 6.8-3 :-)

Obviously you never tried, right? Starting from GDB 6.7.50.xxx all releases of GDB just crash if you try to debug a wx application - try with C::B for example! ;-)

GDB freezed, i had to kill it from a terminal, debug process couldn't stopped.

I tried to run gdb from command line, it works, but this is very uncomfortable for me.

I just attach a CB debug bug report, to strengthen i am not talking to the wind.
Of course the next step will be a CB, wx, gdb, reinstall if nobody can help me.
