Unable to hit breakpoints in MonoDevelop

Question

On my archlinux system I did a fresh installation of:

• mono 3.0.7
• monodevelop 4.0.8
• monodevelop-debugger-gdb 4.0

When I debug an application the debugger doesn't stop on the breakpoints, even not on the System.Diagnostics.Debugger.Break (); code.
And an error windows is displayed with the following message :

Could not connect to the debugger

Does anyone know how to fix it?

Answer 1

I had a similar problem - breakpoints was not triggered while checkbox "Use MSBuild build engine" was checked in the project properties.

Answer 2

This is due to a recent gnome-terminal change. Recent gnome-terminal no longer accepts the --disable-factory argument.

Install the xterm package, then in a gnome-terminal session do the following:

$ unset GNOME_DESKTOP_SESSION_ID 
$ monodevelop

This will cause monodevelop to use xterm as its external terminal and all should be well.

Answer 3

As a workaround untick the "Run on external console" checkbox in your running project settings. You can find this option in the "Run" tab from the settings pane.
