Debugging SpineML_2_BRAHMS code
-------------------------------

If the SpineML_2_BRAHMS-generated code crashes, you, or a friendly
developer will need to find out why.

You can debug SpineML_ 2_BRAHMS by giving the -D option to
convert_script_s2b, which will then compile components with debugging
symbols (the -g option for g++), generate a suitable gdbcmd file, and
then run the simulation with brahms-gdb which will mean you'll be able
to backtrace into the code that SpineML_2_BRAHMS generates. Note that
even if the simulation completes without a crash, you'll still end up
in the gdb command line environment; if you've nothing further to do,
type 'quit' or use Ctrl-D to exit.

You can use the -D option in conjunction with the -r option to ensure
all the components are re-built with debugging symbols
incorporated. It's best to do this the first time you run with -D to
debug.

How to modify SpineML_2_BRAHMS to debug a simulation using gdb:

Find brahms-gdb in the brahms source code.

Install brahms-gdb in your path

Create a gdbcmd file in your home dir containing something like:

dir ~/src/saccsim/src
dir ~/src/brahms
dir ~/src/SpineML_2_BRAHMS/Namespace/dev/SpineML/temp/WU/ConnectionListStaticoweight/brahms/0
run

Add as make of the Namespace/dev/SpineML paths as you need to debug your code.

Modify SpineML_2_BRAHMS/xsl/SpineML_2_BRAHMS_write_script.xsl

Change the BRAHMS_CMD fields to call brahms-gdb instead of plain brahms.

There's a similar scheme for brahms-vg - for valgrind.
