View source of libstdc++ class while debugging program [message #84965]

Dear all,

I use some classes in standard c++ library and I'd like to view the
source of it in debugging mode, just like viewing the source of my own
cpp files when I stepped into some method.

I've tried to add the path of gcc source (extracted from gcc tar ball)
into the "Additional Source Locations" of the Source Tab in the
debugging configuration for project. Could anybody tell me how to
configure CDT to do this?

best regards,

Cheng-Che Lo

Check:
- if your library contains the debug information,
- if the library symbols are loaded when you try to step into a library
function (use the Shared Libraries view or set the "Load shared library
symbols automatically" options of the launch configuration),
If your library is build in the different location you should use the
"Associate with" option of the "Add Directory Source Location" dialog.

I've tried the following steps, am I doing the right thing for this ?

I'm not sure is the library contains debug information, so I get the
source of gcc and re-configure it (libstdc++-v3) with --enable-debug=yes
and put it under /usr/local/src/libstdc++

# ./configure --enable-debug=yes
# make
(have all object files with the source files)

which is the directory I wrote in "Shared Libraries" tab in "Debugger"
tab of the Debug launch configuration. Also, I checked the box with
"Load shared library symbols automatically", it's on.
Besides, in the "Source" tab, "Additional Source Locations" has
both location and association to have the directory
"/usr/local/src/gcc/libstdc++", in this case.

I guess these would let the project use the shared library libstdc++
by the copy I just made (with debugging information -O0 -ggdb3).
Now against the methods of the library, it still stepping over it, not
into it.

Did I get something wrong? Any instruction or suggestion is appreciated.
So much I want to migrate all my c++ programs into eclipse. It'd be
perfect for me is this can got working.

Sorry if this is too *newbie*...

Thanks a lot and a lot.

Check if gdb picks up the correct version of the library. You can do it by
opening the Shared Libraries view and checking if the full path of the
library is correct. The 'S' letter in the icon of the library means
indicates that library symbols are loaded.

I got the full path, and I guess it's the problem.
It uses /usr/lib instead of the one I build in /usr/local/src,
shall I do something on system setting such as ldconfig, change
the order of path..something.. or I can just do it on the project
configuration?

About the 'S', I do got the small red 'S' letter on the icons of the
libraries. Then I guess the symbols are loaded, does that means I can
see the source when I stepped into the library? Don't really know what
to fix, right now I still cannot see the source.

Thanks so much for you patience.

What is the full path of the source file that the debugger is looking for
when you step into a function from the library?
Try this. For example, the path is "/home/dir1/source.c" and the "source.c"
file is in the "/home/dir2/" directory. You can create an additional
directory source location for "/home/dir2" and associate it with
"/home/dir1".

To be sure I didn't misunderstand your instructions,
I try to show the actual values here.

First, in the "Shared Library", I can see `/usr/lib/libstdc++.so.5'
(which I don't know how to change it to
/usr/local/src/gcc/libstdc++-v3/src/libstdc++.so.5 )

Second, the source of libstdc++ is under
/usr/local/src/gcc/libstdc++-v3/src ( source files and modules built
with debugging are all here)

Then, to use the additional source location,
I set the additional source location "/usr/local/src/gcc/libstdc++-v3/src"
and associate it with "/usr/lib"

Am I on the righ track ?

thanks very much for ur time

I could be a bug if you added the path of your library to the Shared
Libraries Directories and it still doesn't work.
Another way is to set LD_LIBRARY_PATH.

What happens when you step into a function from the library? Do you see the
"File Not Found" message in the editor? If so what is the full path of file
that debugger is looking for?
You should put this path in the "Association" field.

Sorry, for misinformation. It seems that gdb on Linux ignores the path set
by the "set solib-search-path" command and loads the symbols for system
libraries from the original location.

Maybe I could ask the maintainer if there's a workaround solution.
Don't know why, I'm quite glad that it's not Eclipse's problem.
Thanks for the information, it could make my life easier.

Thanks again!
