Cross plateform debugging

[Jignesh Patel]

hi,
I have development board installed debian and also Qt library(qt version 5.3.2).
My development platform is Ubuntu 16.04 LTS using qt creator 3.5.1 (based on Qt 5.5.1).
Is it possible to debug application from desktop (remotely from qt creator) to board ?

Thanks,
Jignesh Patel

Yes, you need to set the device up in Tools->Options...->Devices->Add->Generic Linux Device.

One you have that set up and working, debugger should work as well.

Thanks for valuable input,

I have try to do as per your step, but still can not remote debug my application.
I have follow the step:

1. Set up device from Tools->Options...->Devices->Add->Generic Linux Device and when i have test it following message get in windows.
   Connecting to host...
   Checking kernel version...
   Linux 4.1.15-224529-g1a2007a-dirty armv7l
   Checking if specified ports are available...
   All specified ports are available.
   Device test finished successfully.

2. I have set up it in build and run, but here i don't have qmake for my cross platform. it used my development environment. I don't have cross compiler and qmake in my development environment.

When I go for debug my application, My application stop after displaying following message on terminal.
Debugging starts
stdin: is not a tty
Listening on port 10001
Remote debugging from host 192.168.111.122

After some time it gives the warning to stop debugging or give GDB more time.
I have attached snapshot also for reference.

Thanks

Do you have gdbserver on your target board? If yes, which version?

QtCreators debugger log (menu Window > Views > Debugger Log) may contain more information about what went wrong.

Thanks @aha_1980 ,

My GDB and Qt version is as per below:

Board GDB version: GNU gdb (Debian 7.7.1+dfsg-5) 7.7.1
PC GDB version : GNU gdbserver (Ubuntu 7.11.1-0ubuntu1~16.5) 7.11.1
Board qt version : 5.3.2
PC qt version : 5.5.1

I have copy GDB debug log where it stop after "584-exec-continue" in wait.

why GDB doesn't get reponse here, GDB command line is new for me.
How can i solve this issue?

Thanks

@Jignesh-Patel said in Cross plateform debugging:

Sorry, I have no other idea; but I'm currently not using the remote debugging feature.

Board GDB version: GNU gdb (Debian 7.7.1+dfsg-5) 7.7.1
PC GDB version : GNU gdbserver (Ubuntu 7.11.1-0ubuntu1~16.5) 7.11.1
Board qt version : 5.3.2
PC qt version : 5.5.1

Are you sure this is all correct? You should have gdbserver on the board and GDB on your PC.

That said, gdb 7.7.1 is quite old, the Qt versions you use also (but that should not matter for debugging in first place).

If you like to create a bug report you should first try to update both gdb/gdbserver and QtCreator.
