Question

I have Eclipse set up fairly nicely to run the G++ compiler through Cygwin. Even the character encoding is set up correctly!

There still seems to be something wrong with my configuration: I can’t debug. The pause button in the debug view is simply disabled, and no threads appear in my application tree. It seems that gdb is simply not communicating with Eclipse.

Presently, I have the debug settings as follows:

Debugger: “Cygwin gdb Debugger”

GDB debugger: gdb

GDB command file: .gdbinit

Protocol: Default

I should mention here that I have no idea what .gdbinit does; in my project it is merely an empty file.

What is wrong with my configuration?

Debugging

When attempting to terminate the application in debug mode, Eclipse displays the following error:

Target request failed: failed to interrupt.

I can’t kill the process, either; I have to kill its parent gdb.exe, which in turn kills my application.

Running

When running it normally, a bunch of kill.exes are called, doing nothing, while Eclipse displays the following error:

Terminate failed.

I can kill FaceDetector.exe from the task manager.

Process Explorer

This is what it looks like in Process Explorer (debugging left, running right):

Answer 1

The only workaround that I’ve found is to start Eclipse directly from Cygwin.

Start a Cygwin Bash Shell, navigate to Eclipse’s installation directory, and enter ./eclipse.exe.

It would appear that there’s some problem with the way that CDT communicates with Cygwin; the standard output is passed and kill.exe is executed, but kill.exe doesn’t succeed in actually terminating the application unless Eclipse is run through Cygwin. Debugging via gdb gives similar problems; also this is resolved with the workaround.
