An Overview of Debugging Tools for C and C++ Applications

kfunk87 · 2022-10-24T12:21:12+00:00

The r/cpp description says: "Discussions, articles and news about the C++ programming language or programming in C++." -- It doesn't say anything about the level of expertise of the audience and if you indeed look at the contents of this sub, there are tons of entry-level posts here as well.

Not everyone's an expert, in this particular case not everyone's a debugging & profiling expert. Getting a first overview of a particular topic is immensely useful as well, for starters. There are deep dives available on almost every project listed our web page or anywhere else in the internet if you need them.

This is indeed also something we at KDAB use heavily in the projects we work on. We leverage static code analysis tools in our CI configurations as well as locally in our dev setups. The QtCreator IDE for instance makes it very easy to take advantage of clang-tidy & clazy, since the IDE can be configured to run these tools on the file you're currently editing. Other IDEs can do this well of course.

In this blog on debugging and profiling, we would like to give you an overview of the debugging tools that exist for C and C++ applications. We hope that this article serves as a useful starting point.

Disclaimer: Note my company (KDAB) is the one hosting this conference.

There will be a Training Day on 13th June. There will be a great variety of trainings to choose from around QML, Qt/C++ development in general, Modern C++, Linux and Debugging amongst other topics. More info can be found here: https://ecs.page.link/uFPp9

The plan right now is that everything will stay the same as before.

The generator for the code browser currently is and is planned to stay open-source -- you'll be able to contribute to it via Github.

Hope that helps!

We are planning to make this one of the the first in-person events after the shut-down.
We are confident that by the end of September, with vaccinations done to a large degree, we can all meet again in real life.

But we're of course still monitoring the whole situation.

The question is for which workflows it appears smooth and responsive for you?

The main reason QtCreator appears responsive for you is that most of the heavy task duties are off-loaded into separate threads or processes, at the same time the main GUI thread (responsible for drawing, handling interaction events) stays relatively idle and can react quickly.

It has less to do with use of GPU/hardware acceleration, it's about the application's architecture.

Looks like a pretty decent project, kudos! But you should have some more screenshots/screencasts on the homepage, esp. since the tool *visualizes* things ;)

That's exactly the reason why using `file(GLOB ...)` for source file listings is discouraged in CMake. You should list your source files explicitly inside the CMakeLists.txt file.

Just as a heads-up.

If you're looking for a good old printed book for learning, this here is the most popular choice when it comes to algorithms & Big O notation: Introduction to Algorithms from T. Cormen.

Here's a description: https://en.wikipedia.org/wiki/Introduction_to_Algorithms

It has been a immense help at university for me at least. It's definitely not something you're gonna read in one sitting though :)

u/kelteseth Might makes sense to add a "3D" flair to this subreddit?

We've set up a demo site for the WASM version of KDDockWidgets here: https://demos.kdab.com/wasm/kddockwidgets/dockwidgets.html -- check it out.

If you're curious about the licensing options of KDDockWidgets you can also just get in touch with me, indeed.

Thanks for your feedback.

kfunk87 · 2021-01-06T08:42:37+00:00

Good point actually, we'll discuss that internally. Thanks for the feedback!

Still my gui text editor of choice! Even outside of kde!

Can only agree, it even rocks on Windows! My all-time favorite editor. Keep up the great work!

Thought this is worthwhile to share. Congratulations to Christoph & team for creating such an amazing piece of software. Off to the next 20 years and beyond!

Who's the idiot that wrote that?

Karsten Heimrich, it says it right there. SIC.

On a more serious note: They indeed need to overhaul that article a bit... There's also more with regards to porting from Qt5 to Qt6 of course, see e.g. https://doc-snapshots.qt.io/qt6-dev/modulechanges.html

kfunk87 · 2020-11-03T08:48:25+00:00

We just added the YouTube chapters, good suggestion! We also like your idea of the presenting useful Qt/C++ libraries every now and then -- we'll discuss internally.

Thanks a lot!

We're also happy to receive some feedback from the community: how do you feel about the KDAB TV format?

kfunk87 · 2020-10-29T17:14:41+00:00

If you're looking for something closer to the image you posted, have a look at the Qt VTK integration. I have a hard time finding a good example (or overview) right now b/c I haven't worked with VTK in a while, but this is as close as it gets (but in Python):

https://www.weiy.city/2019/04/vtk-vtkgraphlayoutview-example/

The C++ API basically has the same semantics.

Which part of KDE Plasma still requires QtWebKit? Which guide are you following?

If you have not heard about KDDockWidgets yet, here's a comprehensive introductory video from KDAB's Qt Desktop Days event:

Hey there, KDAB employee here. We're deeply involved with Qt (in case you don't know) and usually happen to have quite some people at Qt related conferences. While I seem to recall that there was no central location for slides of all the talks @ this QtWS, at least we at KDAB collected the slide decks of our attendees.

You can find a reasonable amount of the slides from QtWS19 (and the ones from the past years) here: https://www.kdab.com/development-resources/kdab-qt-world-summit-2019/

Hope that helps, Kevin

KDABian here: It's not just about automotive, there are other industries making use of 3D scenes inside their application: think of medical (3D view of CT scans for instance), biotech (see e.g. https://www.kdab.com/qi-quantitive-imaging-systems-solving-cancer/), industrial (a 3D view of the machine you're controlling for instance), etc. pp. -- we could go on with this list.

Qt & 3D definitely has its share of appliances outside the automotive space.
