I would like to ask how can i debug simpleFoam solver in ddd. I understand that i need to recompile the code. What i need to changde and where?

Thank u very much

Look in .OpenFOAM-1.3/bashrc, you have to comment out the following option:

export WM_COMPILE_OPTION=Debug

and re-source the file. After that, go to OpenFOAM-1.3 and run

./Allwmake

that's all...
Remember I will have both the optimized and debug versions installed and you can switch between them with that flag.

It might be easier to only compile (a copy of) the conflicting command (unless your bug is in one of the libraries). Search on this forum for FULLDEBUG.

Hi

thanks a lot for the tips

I compiled the code with
export WM_COMPILE_OPTION=Debug activated and i obtain the following type of errors:

bin/linuxGcc4DPProf/setFields
/usr/bin/ld: cannot find -lOpenFOAM
collect2: ld returned 1 exit status
make: *** [/home/gda/OpenFOAM/OpenFOAM-1.3/applications/bin/linuxGcc4DPProf/setFields] Error 1
+ wmake mapFields


/usr/bin/ld: cannot find -lOpenFOAM
collect2: ld returned 1 exit status
make: *** [/home/gda/OpenFOAM/OpenFOAM-1.3/applications/bin/linuxGcc4DPProf/foamInfoExec] Error 1
gda@tzapuu:~/OpenFOAM/OpenFOAM- 1.3$


Does anybody know how i can fix it?

thanks

You don't have the debug version of the library compiled. If you follow Massimilianos steps so recompile everything you will end up with a whole set of debug libraries.

E.g. where my libOpenFOAM is now in
.../linuxGcc4DPOpt/libOpenFOAM.so

it will then be in something like
.../linuxGcc4DPDEBUG/libOpenFOAM.so

With you it actually looks like your binaries end up in 'linuxGcc4DPProf/' but anyway you don't seem to have libraries in the corresponding library directories ($FOAM_LIBBIN).

(you could always try the local compilation option in my post above)

Hej,


I am trying to debug my own solver in OpenFoam. For this I added a line in
the Make/options:
------------------------------------------------
EXE_INC =\
-DFULLDEBUG -g O0
------------------------------------------------

and I used the comand line : gdb <name_solver> <case_name>
But It seems to be be something wrong in this line.

Could someone give some instructions on how to use interactive debugger in
openFoam step by step for person who is new in this area?

Thank you in advance,
Rita

Hi
I am a beginer with OpenFOAM.
Can i trace a solver line by line in debug mode?
if yes, how can i do that?
Thank You.

Yes you can. All you need to do is recompile OpenFOAM with the debug option turned on (see etc/bashrc file in OpenFOAM installation). Then, launch application in gdb and step through the code
