Personal Notes: - There are two parts in a library usually: includes and libraries. İnclude directory has a bunch of header files and lib directory has those pre-built binaries. - Dynamic library is loaded(linked) into program at runtime, dynamic library can be anywhere and you do the linking whereas static library is put(compiled) into your executable program - We have to point our compiler to header files (include files) and then we also have to point out our linker to library files.

[@zvxcvxcz]

And don't forget the library names :P

[@Djzaamir]

Great stuff as always , and yes linking libs from source code video would be a nice add to this series

[@svenbtb]

I know I've probably already said this 100 times but thank you so much for all of your videos, they seriously help me so much. A lot of people who program aren't the best writers lol so it's really hard for me to follow along with most textbooks and written content from MIT, but watching you and hearing your clear explanations and SEEING how things work is so, so helpful, and makes it easier for me to code along with your examples (and pause the video to experiment if I have a "What if I do this?" moment) and to have it stick in my mind better

[@seayellow5834]

A really great thing about your video is that you not only tell us what and why to do, but also conduct those little experiments that deepen our understanding. Well done.

[@jhfoleiss]

Coming from a GNU background I always found Visual Studio projects confusing to setup. This video cleared a lot of my confusion about using external libraries. Thanks!

[@zvxcvxcz]

Yeah, dealing with IDEs is always such a mess... the syntax highlighting is nice though. I find things like Sublime to be a nice middle ground.

[@snuffbox2006]

great video. It often feels like so many other resources assume that one has this knowledge "a priori" and then you are stuck. You've shown that it is not that difficult, but one needs to learn it.

[@jimmylander2089]

Nobody at university shows you this stuff. If I weren’t proactive in my studies I’d still be stuck writing cli programs. We’ve covered 3 languages and no one’s touched upon the topic of third party libraries. The closest we’ve gotten to an explanation was “just do ‘pip install’ and the manager will handle it” (python). No mention on basic stuff like having ‘requirements.txt’ or using virtual environments (especially on Linux). So in conclusion: Thanks for the awesome videos! Really helpful

I really enjoyed this tutorial as always. However, I will say that I was pretty confused in the earlier parts of the video. I'd still consider myself kind of a beginner so when GLFW was brought up, I had to go on my own learning-tangent to find out what openGL and GLFW were.

Great explanation, thank you. Despite years of coding in different IDEs and languages, I always got confused how to setup C and C++ projects in Visual Studio.

[@georgesealy4706]

I used Visual Studio going way back into the early 1990s. No doubt, it is great in that it provides a lot of automation and help to get things done. It is the professional developer's choice for doing all kinds of projects. The thing is for beginners I would say using Eclipse is better because it is simpler and the developer has to understand what is actually going on.

Hi Cherno (Bill?). When you get to dynamic libraries in a future video, could you point out the differences between *nix and Windows in this regard. In particular why Linux likes things like theshared.so, theshared.so.1 and perhaps even theshared.so.0.1. Oh and there's ldconfig (?). Keep up the great videos, you are very good at explaining things.

[@smileynetsmileynet7922]

Yes please. Please go over linux dynamic linking. And maybe also other dynamic linking, such as in your own os.

1:00 i completely agree, i also hate linking 3rd libraries, but be careful to distribute other source code within your project repo, it might just go against their end user agreement

[@Nevarek_]

It's not that Mac/Linux particularly love building code, though some people do really just like compiling everything from source for whatever reason that suits them. In which case the statement is accurate. There are other common cases to consider. I'll elaborate with a few examples. It's often the case (in some fields) that you will be targeting a different architecture and are building an executable for another computer to run. You can be building a project for proprietary hardware like an embedded system. This one is pretty easy to understand, your computer has a lot of extra stuff compared to, say, a smart lightbulb. Or manufacturing equipment that makes paperclips using various sensors and actuators. Even traditional application development runs into issues, now that some 32-bit architectures are being deprecated. MacOS stopped supporting 32-bit architectures completely. Some libraries are only to be used on 32-bit systems and you have to unfortunately re-build ancient code to support a 64-bit architecture, and sometimes you'll have to rewrite sections of it. Hence why handing someone a library file that can't be run would be a waste of time. Another situation most people will run into is building an executable for a Raspberry Pi to run. It's going to use a different architecture than a typical computer because the hardware is just different (hence the intrigue of having a Raspberry Pi). You'll probably need to build a lot of dependencies from source if you want to use other people's code. You absolutely do not want to compile a large project on your Raspberry Pi. Why? Because it will take like five hours.

Thanks for doing this video. I was a pretty good C/C++ developer back in the 1990s and very early 2000s. Then I started to do lots of C#, Java, Web Dev, and database development. So after all that time I forgot some of the detailed nuts and bolts of where things go to do C/C++. Oh yeah, I remember now, LOL. Incidentally, after doing all that stuff for many years, I still like C/C++ the best.

[@funkynicco]

Actually the version of visual studio a library was built with does matter because the binary may reference older SDK, linking to older libraries. And you might run into conflict issues when mixing different versions. It may work fine for some libraries like GLFW but it should in general case be discouraged. You'll know you're getting conflict errors in form of somewhat descriptive linker errors. If the library API is only passing primitive types (int, bool, etc) then there shouldn't be an SDK conflict but if you have a library taking in anything from STD/STL as parameters or return values then the memory layout may have been changed across SDK versions. Linux have bigger issues with binary compatibility model (linking to linux libraries) due to being updated so frequently, which is why the compile-it-yourself is so common on linux (apart from open source community).

[@jordanstafford5110]

Doesn’t work for glfw anymore, the glfw3.lib file isn’t static only anymore, apparently glfw3_mt.lib is the static build lib now
