[cdt-dev] Debugging tutorial ?

[Oodini]

Hello,

I am desesperatly trying to debug my project with Eclipse.

The reference documentation is not up to date, as an official tutorial I found (from an old EclipseCon).
Moreover, the documentation is poor, and just reformulates what there is in the GUI, without explaining anything.

Also, please consider that many people wishing to use CDT come from Windows, and don't know anything about gdb.

Thanks for your work, but I guess you could have more people using your work with better docs (which are, by the way, sparsed on the Eclipse sites).

Hello,
I am desesperatly trying to debug my project with Eclipse.

If you right-click on your project and select
"Debug As->Local C/C++ Applications" it should start the debugger.

The reference documentation is not up to date, as an official
tutorial I found (from an old EclipseCon).

Yes, the documentation included in eclipse has not been updated
in too long. Contributions would help get the ball rolling.

come from Windows, and don't know anything about gdb.

We desperatly need someone to take charge of the Windows side
of the CDT debugging. Someone that would try out features
and report problems regularly would already be a great help.

Thanks for your work, but I guess you could have more people
using your work with better docs (which are, by the way,
sparsed on the Eclipse sites).

I'm glad you took the time to write this email. If people
give up without letting us know why, we can't improve.
I can't promise to get the docs all better soon, but your
point will hopefully remind us to keep the docs updated.

Thanks

Marc

I managed to launch the debugger, but gdb doesn't stop at my breakpoints.

Actually, I am developing on Linux by now, but I come from Windows, and so doesn't know anything about gdb.
And I guess that people from me could be the main source of CDT users :
Windows users will use Visual C++, and Linux users will use emacs, vim... (that's what happens at my office).

I would be OK to be associated with someone knowing well the Linux environment and CDT.
I could provide some newbie questions and problems, and write the doc. But I need support.

You may want to look in the CDT forums, which is better suited
for new users.

Great. On the CDT wiki, it mentions how to get started with
contributions to CDT:
http://wiki.eclipse.org/Getting_started_with_CDT_development

You can also open bugs at
https://bugs.eclipse.org/bugs (under tools->CDT)
and contribute some documentation in whichever format
is easier and we can work together to include it with CDT.

Thanks!

It may happen if you compile your program without debug information
("-g" switch for gcc).


BTW, Qt Creator detects this case somehow and warns user about it. It
would be great if Eclipse does the same.

If you have time, could you write an enhancement bug?

Thanks

I have filed a bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=376725.

I also figured out how Qt Creator performs this checkand described it
there. However I am not sure whether this way is acceptable for CDT.
Could we make a dependency on objdump?


Thanks,
Anton

Actually, I had to change the launcher.
In the dialog box, when you click on the question mark, after several seconds, you get :
"The context help for this user interface element could not be found."

Obviously, there is nothing about this setting in the general documentation...

I am going to ask some information in the forum.

Do I really need to dowload the Eclipse sources to write some docs ?

If you want to modify the doc that is part of Eclipse/CDT itself
that is a modification in actual plugins. But if that is too much
of a hurdle, you can also add documentation to the wiki FAQ:
http://wiki.eclipse.org/CDT/User/FAQ

If you want a review of what you write first, then write a bugzilla
include the text you propose, and once it is reviewed, you can feel
more confident about adding it to the wiki.

Parts of this wiki FAQ could eventually make it to the documentation
plugin.

Thanks

If you want to modify the doc that is part of Eclipse/CDT itself
that is a modification in actual plugins.

If the CDT moved to Mylyn WikiText-generated documentation, the docs
could be entirely done on the web and then translated into .html for
inclusion in plugins (like now) for releases or periodically.
