If you encounter problem with interrupting octave (i.e. "^C" is only | |||
printed when you press ctrl+c and control is not transferred to gdb) | |||
then you might follow following steps (which should work always). | |||
# Start gdb<br/><syntaxhighlight lang="bash">> gdb octave</syntaxhighlight> | |||
# Catch loading of your oct-file ("file" below is a regex matching name of your oct-file)<br/><syntaxhighlight lang="bash">(gdb) catch load file</syntaxhighlight> | |||
# Run octave<br/><syntaxhighlight lang="bash">(gdb) r</syntaxhighlight> | |||
# From octave request loading of your oct-file by calling function<br/><syntaxhighlight lang="matlab">octave> x = file(y)</syntaxhighlight> | |||
# Control will switch to gdb just after oct-file is loaded and at this point all symbols from oct-file are available so you can either set up a breakpoint at particular line or at function entry.<br/><syntaxhighlight lang="bash">(gdb) b file.cpp:40</syntaxhighlight> | |||
# Resume execution of octave by<br/><syntaxhighlight lang="bash">(gdb) c</syntaxhighlight> | |||
and debugger will stop at the breakpoint defined. | |||
