RE: [dsdp-dd-dev] GDB source lookup issues
|
Pawel and all,
The following may be helpful if you decide to implement the source
lookup that extracts the source information from modules. It's a part of
my discussion with Daniel Jacobowitz, I don't think he would mind me
posting it.

DJ: I believe that it will return all source files for all loaded
objects, no matter where they come from.
GDB doesn't know anything about shared libraries before they are loaded
- it's just too difficult to guess which copy of a shared library will
be loaded at runtime. So I guess you would have to rerun the command
when libraries are loaded or unloaded. We could add a command to list
source files for a particular shared object only.

DJ: I really dislike changing the behaviour of existing commands - we
don't know what front ends might be using. If you don't mind I'll post
this issue to the GDB mailing list and copy you?

Subject: [dsdp-dd-dev] GDB source lookup issues
Hi Tobias and All,
I'm want to cross-post the following discussion from cdt-dev, which we
mentioned in this mornings DSF-GDB meeting:
http://dev.eclipse.org/mhonarc/lists/cdt-dev/msg11583.html
It seems that Windows and cross platform development with GDB could be
much improved if this source lookup issue was addressed. If after
fixing bug 219920 source lookup continues to be a problem for your use
cases, I recommend that you follow up and contribute to fixing this
issue in CDT.
Cheers,
Pawel
