Came to learn about CMake, and I ended up learning all the c++ basics I've been missing my entire life. Thanks, mate.

I was frustrated with external libraries in C/C++ for a very very long time. I even stopped working with C/C++ at a point. Just finished this video, now I can build, link and install any external libraries or open source tools out there in the internet. I finally understand whats going under the hood. Thank you soo much!!!!

As someone who has been trying to learn about CMake, this tutorial series is super helpful and criminally underrated. Thanks!

Taught me everything I need about CMake, the best and the most practical tutorial there is. Thank you so much, you've gained a happy subscriber

Literally the best hands on tutorial on CMake you will ever find.

Idk why but the tone you have makes me more focused. Thanks

I started building a large BASH program last month, and the harder it gets to manage, the more I'm starting to want to use C++ instead. In you come just a few weeks before with the exact tutorial that I needed to convert all my shell scripts to a structured cpp project. Thanks a lot!

literally goated. I've been trying to find a normal humanized explanation on how to link libraries in different places for the past 3 HOURS with no success with no luck until I got to your video!

Thank you very much for this brilliant series! I found it very helpful. Great job done! Keep rocking!

Thank you! I've been avoiding C/C++ very long time because of build system complexity. You make it clear.

Very useful. Thanks a lot for taking the time to record and share this!

This is awesome stuff dude. Just exactly what I needed to learn right now.

Thank you for your invaluable lecture. I learned a great deal from this video. To capture the return value, try printing it using the command "echo $?".

These tutorials are great! Thanks for making them!

I like almost any content you create for us

Made my first installable c++ programme today. Thanks to you. I've been learning make and cmake lately.

Love your videos, and really digging your logo!

Really great contents! Thanks for creating this video

my man the info is useful and I'm glad that people enjoy learning a lot but please get to the point lmao. I just want to learn how to create a library and link it to a project in cmake, I don't need to hear a whole tangent on namespaces

Thanks for your knowledge!

I think you can return the exit value of the main function by typing echo $? on linux at 27:34

you did not remove the relative path inclusion of adder.h in main.cpp, instead you could have add #include using namespace mearlymath;

SEE ORIGINAL EPISODE 2, in episode 3 you would need what you see in original episode 2

Very good tutorial you earned another subscriber and a like ! Thank you zues

Given that in this example we are building the library and the executable adding a add_subdirectory() function to the parent CMakeLists.txt file will chain the projects. Then building the executable will build the library as well

Here to stomp the comp... 💯

Thank you!!!

Thanks for your time to teach people something. Just a little feedback: In the previous video, you were using VS Code and I think it was easier to understand the file hierarchy. Also, not seeing the current directory in the command line prompt confuses things for us :)

Please "sudo apt install tree" and run the tree command from time to time. It'll make it easier for us to see the file structure, but thanks for the vid.

-f shouldn't be needed on rm -R. It doesn't do what some people assume it does, and what it does do is hide some error messages that may indicate you made a mistake typing the command. If the files you are deleting exist and your user has permissions on both the files and their containing directories, rm -R (or just rm -r) should work fine

echo $? for getting the exit status of program. Thanks for the tutorial.

Btw, you made the include file available but you did not change the include directive, its still using a relative path

I was about to make a comment the other day about how videos seem to me in numerical order but not in chronological… took me a while to realize it was indeed the case

17:24 also add adder.h in add_library(mearlymath adder.cpp adder.h) // those who are getting errors

Thanks!

echo $? will show 5

Thanks alot

Thanks

unable to do same things in cmake 3.10.2

where can we find trimerdemo and trim file

Hi, 27:47 echo $? to get the last return value. Thanks!

Amazing, maybe a little bit of zoom on the code, content stays perfect :] Thank you

Im a total newb in cmake and thanks for the video. I have some questions. 1. 00:26:56 In my case this didn't work and cmake gives me an error like this: /usr/bin/ld: cannot find -lmearlymath. So I erased target_link_directories(testsome PRIVATE ${CMAKE_SOURCE_DIR}/../../SomeLibDemo/cpp/build/) and replaced target link lib with target_link_libraries(testsome ${CMAKE_SOURCE_DIR}/../../SomeLibDemo/cpp/build/libmealymath.a) and this worked. Why is that /usr/bin/ld: cannot find -lmearlymath error popuping? 2. 00:33:30 my workspace shows up with this cmake error: install TARGETS given unknown argument "include". I get the meaning of DESTINATION and PUBLIC_HEADER from the offical docs, but what is lib and include?

9:00 at the drop of a dime. Haha. I'm going to use that one.

I really don't like the cmake thing , still can't compile a simple project . cmake also need the so file start with `lib`. And there are so many similar command make people confused. I really hope rust and cargo replace all those cmake and cpp things

27:50 "echo $?" or "echo $status" for csh

I suggest adopting "Solve one problem Well", by sticking with talking about cmake. No Linux-commands, no C/C++. it's a better way to keep it short. Returned value from a command: echo $?.. Try 'false;echo $?;true;echo $?' You really shouldn't create confusion about which folder you are in. Let the prompt show!

If you say definition all the time than, eventually, you will be right 😅

Have you tested your project with CMake 2.8? No. So stop claiming it's the required version and use something current. Then you won't have to worry about bumping the minimum required version each time you want to use a feature.

The original was easier to follow, you mix things that are linux usage related thats not too important for cmake

CMake generated Makefiles are artificially long - you could typically throw out more than 90% of its content. A handwritten Makefile for such a simple example would also only consist of a few lines. Thing is that handwritten Makefiles require you to specify all the dependencies and get all commands right for e.g. building a library. What I don't like about cmake: there is a lot of black magic happening behind the scenes. This discomfits me. Same is true for GUI vs command line.

5:18 that's kinda misleading and wrong, you don't need 2 hundred lines of Makefile to compile a programme, most of the stuff cmake puts into makefile are not useful for simple projects and moreover are a bloat imo

Please please - this music overlay is execively annoying!

I'm sorry, this tutorial is too "all over the place" i.e. not concise. The crucial aspects could have been covered in 10m - 15m. Video quality is low, even at 1080p (doesn't seem sharp), and the text editor is way too small. Learning C++ tricks is not the topic, tutorials should be focused.

ya just have no clue what cmake really is …. 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️

Thanks
