Yes, I'm able to debug the externalsrc component. I can see variables, set breakpoints, step/next through the code etc. (so the symbols are valid). And local changes to the externalsrc component are reflected when I debug.<br>
<br>
But I can't list the externalsrc component source code from within gdb (or find it anywhere in the image). The source for all of the other components is in the image (and I can list it in gdb). When I try to list the code for the externalsrc component, gdb
prints this error message:<br>
"[path on my <strong style="text-decoration: underline;"><em>build</em></strong><span style="text-decoration: underline;"></span> machine]/sourceFile.c: No such file or directory."
<div><br>
If I don't use externalsrc at all, I can debug all of the components and list source code for all of them from within gdb.<br>
<br>
So, I can't solve how to get the externalsrc source code into the image. I don't mind if I have to use "set substitute-path" from within gdb if externalsrc source files are put in a different place (although, it'd be ideal if they were put in the same place).<br>
<br>
Thanks<br>

Can you check if -dbg package for extrnalsrc component is installed ?<br>
secondly, does the debugging work if you dont isue externalsrc for<br>
this particular component.<br>
