How debugger with Qt on target from host?

[Duck]

The error in case 1) might be that you did not hit the <F10> key to start debugging-with-stop-at-main, but something else.

The error in case 2) might be that you did not specify the sysroot properly. It pretty much looks like you did not set any at all, so gdb found a file /lib/libc.so.6, but that's the one from your host system, not a copy of one from your target system.

Check your tool chain settings in Qt Creator, and if that does not help, post a full debugger log (contents of the right pane of Windows->Views->Debugger Log).

[goli]

how do you connect the host to the device from QtCreator?
when I try to define the the linux device in qtcreator > Tools > Options > Linux Devices, i get this message:
"Connecting to host...
SSH connection failure: Timeout waiting for reply from server.
Device test failed."
I need to debug on ARM32 system...

[Duck]

Can you connect to the device using ssh, from a normal shell, without entering a password (i.e. using authorized_keys)?

[goli]

yes, i use the command: ssh -o ‘StrictHostKeyChecking no’ root@1.0.0.1

when i go to Debug > Start Debugging > Attach to Remote Debug Server, and init the host and port, and all other attributes, I insert into debug mode, but the program does not stop in the breakpoints i put in the files on host. when i pause the debug it stop in assembler code.

The output i get for the debug is:
Could not load shared library symbols for 48 libraries, e.g. /usr/lib/libglib-2.0.so.0.
Use the “info sharedlibrary” command to see the complete listing.
Do you need “set solib-search-path” or “set sysroot”?Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.
.

[Duck]

1. Try change your setup in a way that allows ssh connection without any extra options.

2. This looks like you either did not specify the sysroot correctly, or the sysroot misses some libraries. At the very least, copy the contents of /lib/* from the target to $sysroot/lib/* on the host.

[goli]

1. what do you mean "ssh connection without any extra options"?

2. I init the sysyroot to be the directory to the copy of the target root on the host, and I get this error:
   "Unable to find dynamic linker breakpoint function.
   GDB will be unable to debug shared library initializers
   and track explicitly loaded dynamic code."

I can't find any information about the right arguments for the debbuger...

[Duck]

1. Just ssh root@1.0.0.1, no -o ‘StrictHostKeyChecking no’

2. Pastebin the debugger log and put a link here (contents of the right pane of Windows->Views->Debugger Log)

[goli]

1. when I try only ssh root@1.0.0.1 , I get this message:
   "RSA host key for 1.0.0.1 has changed and you have requested strict checking.
   Host key verification failed."

2. The copy of the board root is /ROOT
   The executable and the file for debug are in /DEBUG-ROOT/MyProject
   the debug output :

Hi everyone,

I'm currently having the same issues as you with settings sysroot path since I'm using QtCreator 2.5.1 (before I used 2.2.1 and no problem at all with remote debugging).

Have you successully find out this issue? I'm curious about the solution!

Thanks

[goli]

Hi Noth35 ,

Sorry but i didn't figure out how to fix this and make it work....
however, I understand that we need to config this property to be the directory of the copy of the device filesystem on the computer(the root of filesystem).
when I config this i get into debug mode, but the debbuger can't stop on breakpoints...

I will be happy to know if you will find solution for this isue.

[Noth35]

Hi goli,

Thanks for your reply. I did really hope you had the solution.
I'll continue to look for a way to set it, I will reply if I'll find something...

So you debug with printf/qdebug ;)?

[tobias.hunger]

In Qt Creator 2.5 the sysroot is part of the Qt version. Since that is not an ideal place in 2.6 we have moved it again;-)

Sorry for the inconvenience. I think the 2.6 version will fix quite a few issues wrt. remote devices and hope we can keep things in this area a bit more stable going forward.

[Noth35]

Thanks for your reply.

Is that also true for version 2.4? Seems to have same issue with it...
I'll keep using previous version of QtCreator, awaiting 2.6.
