Debugging using gdb

Compile without the release option to enable debugging:

$ cmake -H. -Bbuild -GNinja # (not using release option)
$ ninja -C build

Then run astroid using gdb (here without starting the automatic polling):

$ gdb --args build/astroid --no-auto-poll

after a crash, type e.g. bt at the gdb prompt to get a backtrace.

Profiling using gprof

Compile with the profiling option:

$ cmake -DENABLE_PROFILING=ON

To profile, run astroid:

$ astroid --no-auto-poll # no automatic polling

this creates the file gmon.out in the current directory. Use gprof to parse the output, and gprof2dot and dot (part of graphviz) to graph the output:

$ gprof astroid | gprof2dot -s | dot -Tpng -o prof.png
