CodeLite IDE

I can successfully build and run my program. But when I try to debug it I get a pop-up window that says:

Could not launch terminal for debugger.

I searched through CodeLite settings - all gdb-specific settings are empty. If it matters I use custom build utilizing my Makefiles.

My system is RedHat 6.5 x64 with its standard tools (gcc 4.4.7 and gdb 7.2-60).

Hi,

Often that message means that you don't have the 'xterm' package installed...

I have xterm installed:
and I can run it with Alt-F2.

Any other ideas?

Any other ideas?

You say the Gdb Settings menu is empty. Does that dialog have the full path to your gdb in the top field? If not, try adding it.

If that doesn't help, please turn on debugger full logging (the checkbox at the top of the 'Output' tab in the Debugger View). Then try to debug your project and post the output here.

The other thing is your gdb version. gdb 7.2 is old now, and untested by us. You could try installing the current release. It's not hard to build once you got the dependencies installed (e.g. the ncurses devel package), and if you configure it with --prefix=$(pwd) it won't interfere with your RedHat version. You can then put its full path in Gdb Settings.

Another workaround (if you don't really need the terminal) is to disable terminal while debugging.
This is done from:
project settings->common settings->general->This program is a GUI application

Thanks for everybody trying to help me. I did the following, but still have the same error:

I switched to using newer RedHat dev tools 2.1:

gcc version 4.8.2 20140120 (Red Hat 4.8.2-15) (GCC)
GNU gdb (GDB) Red Hat Enterprise Linux 7.6.1-47.el6

I set the full path to gdb:
Settings/GDB Settings/Debugger Path:
/opt/rh/devtoolset-2/root/usr/bin/gdb

I enabled debugger full logging, but I get nothing there when I start debugging.

I tried using the built-in Codelite terminal. The terminal appearance changed when running without debugging, but this doesn't help with debugging.

This is a console application, not GUI. After I ticked "This Program is a GUI Application" I got the following error trying to run it without debugging:

Program exited with return code: -6

When I try to run it with debugging I got the following in debugger log:

More details when trying to start debugging session if it helps:

I get an empty terminal window with the title:

Debugging: "my_executable params"

and an empty pop-up window saying:

Could not launch terminal for debugger.


So it looks like the terminal is actually launched, but then something bad happens. BTW if I change to use CL built-in terminal debugging session still launches the external xterm.

So (iiuc) the program starts, but exits too early.

What happens if you run the program inside gdb 'by hand', not using CodeLite? Does the same thing happen?

The programs works fine outside of Codelite debugger session. I can run it as is, I can debug it in gdb.

OK, so it must be a CodeLite problem somehow.

What happens if you create a new workspace/project using one of the template ones (Workspace > New workspace or from the Welcome page)? Does that debug successfully?

Our problem is that neither Eran nor I have access to a RedHat install for testing. However I can test in Fedora (various versions) and I'll be happy to do so if you can upload (or send me) a project where debugging fails for you. Ideally that would be a simple project that fails to debug; otherwise it would have to be your real program, if that's acceptable to you...

I created a simple console app for gnu g++. I was able to debug it, though the first line in the debugger terminal is a warning:

&"warning: GDB: Failed to set controlling terminal: Operation not permitted\n"

Does it help?
