As I type:

break /home/.../v8p0r0/sources/telemac2d/lecdon_telemac2d.f:31

gdb echoes:

No source file named /home/.../v8p0r0/sources/telemac2d/lecdon_telemac2d.f.
Make breakpoint pending on future shared library load? (y or [n])

As run to breakpoint of lecdon_telemac2d_f, gdb supposes this file has no line, and gdb prints:

Single stepping until exit from function lecdon_telemac2d_,
which has no line number information.

About the error "which has no line number information", as far as I know, it is a bug of gdb.

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	Ok i see the issue. You need to copy the key fflags_gfo_debug: from the original systel.edf.cfg in yours otherwise it is empty. So here you are not compiling with the debug options. Because flags_gfo_debug is empty

Sorry, did you mean fflags_debug_gfo instead of fflags_gfo_debug???
Because as I look at this file
svn.opentelemac.org/svn/opentelemac/tags...nfigs/systel.edf.cfg

I only see this configuration which has fflags, gfo and debug

#
# Gfortran info
#
fflags_gfo: -cpp -fconvert=big-endian -frecord-marker=4 -DHAVE_I16
fflags_debug_gfo: -g -Wall -fcheck=all -fbacktrace -fbounds-check -finit-integer=-1 -finit-real=nan -ffpe-trap=invalid,zero,overflow

Thank you yugi,
I put these lines into my file but it still doesn't work
After re-installing Telemac, I ran telemac2d.py t2d_gouttedo.cas, cancelled running program to take executable file and then ran gdb, I got this:

In the first picture, I already set breakpoint to lecdon_telemac2d_

Next I type "run" and gdb goes to the lecdon_telemac2d_. And you can see sentences "Single stepping until exit from function lecdon_telemac2d_, which has no line number information"

I also try to set breakpoint at source file but gdb can not find out it.

Is it normal for debugging in Ubuntu? I expect my gdb can debug like this user (he posted in here

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	It is not normal something must still be wrong with your configuration. Can you post your systel.cfg again ?

yugi OFFLINE openTELEMAC Guru Posts: 851 Thank you received: 244	Have a go with this one. I update both created a hpc.debug and a gfortran.debug configuration. That should do the trick. By the way do you check which configuration you are running with ? Do you set USETELCFG or add the option -c ? Attachments: systel.cfg (3KB)
