Hi,
I am trying to print rhs for each time step of my simulation using gdb.
I tried to configure with CXXFLAGS='-g' and CFLAGS='-g'.
but when executing gdb nrniv i get the symbols load but i cannot access files in the oc folder.
I am trying to step through nrn_rhs proc at treeset.c
Is there anything else i should do except using the flags?
Thanks in advance
Roy
Trying to print _rhs using gdb
Re: Trying to print _rhs using gdb
You can only use gdb if you build from sources. The nrniv.exe and libraries distributed in the setup.exe installer are stripped
by the nrn/src/mswin/batch/instalmingw.sh script to minimise the size of the installer.

Re: Trying to print _rhs using gdb
Hmm. I guess your mention of CFLAGS is a clue that you are building from sources on MSWin
Are you using MingW or Cygwin? In any case, I presume you copy the nrniv.exe and nrniv.dll over the c:/nrn/bin files of an existing installation.

Re: Trying to print _rhs using gdb
So i should have mentioned it in the first post,
I am using bash on windows - which is a ubuntu linux shell on windows 10 (pretty new feature for win)
And i go to '~/neuron/nrn/x86_64/bin$' and run gdb nrniv from there.
When trying to set a breakpoint at nrn_rhs i cannot
typing (gdb) break nrn (then hitting tab for completion)
i get:

nrn_global_argv

Maybe the names are not loaded at the beginning because the dynamic library has not been loaded. Try
run
(ctrl)C
and then see if you have more names available. On a ubuntu system I see
