Hello,

i've already posted this issue on the tracker but was directed here.

My setup
I have the following setup:
I'm programming for an embedded ARM target running ChibiOS/RT:

Code: Select all

[ARM Target with ChibiOS] <--> JTAG <--> openOCD patched with ChibiOS thread support <--> arm-none-eabi-gdb <-> codelite

Software versions:

Ubuntu 12.04.1 LTS 64 bit
Codelite 4.1.5770 from repository
OpenOCD master, patched with #1, #2 and ChibiOS support

The setup works fine with command line gdb and Eclipse, I think it can be considered very stable.

Now to the problem:
Debugging works great if i disable thread support in OpenOCD - basically it then only shows the current execution. But once I move to threads, it works fine - but if threads are destroyed (this happens for example when initializing the RTOS), codelight chockes on the gdb output.

Most probably this is cause by a parsing error of the "info threads" command, which is nicely illustrated in this screenshot:

codelite_threadbug.log

The corresponding lines from the gdb log:

Code: Select all

DEBUG>>&"info threads\n"
DEBUG>>=thread-exited,id="1",group-id="i1"
=thread-exited,id="1",group-id="i1"
DEBUG>>=thread-created,id="2",group-id="i1"
=thread-created,id="2",group-id="i1"
DEBUG>>~"[New Thread 1]\n"
DEBUG>>~"  2 Thread 1 (Current Execution :  : No RTOS thread)  main () at main.cpp:69\n"
DEBUG>>~"\nThe current thread <Thread ID 1> has terminated.  See `help thread'.\n"

DEBUG>>~"\nThe current thread <Thread ID 1> has terminated.  See `help thread'.\n"

Best,

A better way of getting the thread information is probably -thread-info

Initially this was the way it was done, however, it did not work quite well on old machines with an older version of gdb.
However, there have been few years since that.. so I changed the code to use the -thread-info command.

In addition I replaced the column 'Information' with 3 columns: Function | File | Line (to make it more readable)
This change is committed to trunk
