It could be either using CMAKE or Bazel.
I have tried checking YouTube but all of the installation procedures are outdated and make use of the zip file
protobuf-cpp-3.11.2.tar.gz which doesn't exist anymore on the GitHub repo.
I would be grateful if anyone could help me out. Thank you

Struggling to install protobuf
Hi Everyone,
I hope you're all doing well. I am trying to learn about Protobuf and proceeded to install the protoc and C++ runtime for it. I have been stuck on installation for 3 days and nothing seems to be helping. I am trying to install it on WSL 2 Ubuntu-24.04.
These are the steps I followed:
1) Installed the dependencies:
sudo apt-get install g++ git bazel
git clone `https://github.com/protocolbuffers/protobuf.git`
cd protobuf
git checkout v29.1
git submodule update --init --recursive
2) Build the project:
bazel build --enable_bzlmod --enable_workspace :protoc :protobuf
Errors encountered:

License manager for a desktop application
Any recommendations for a good license manager? Back in the day nearly 11 years back I had some experience with using flexlm and is that still used or any other recommendation. The usecase is to license a desktop scientific application. Appreciate your help. This is to support an app built in C

How to achieve senior level in C++ software engineer?
I've pursued C++ software path for an amount of time. Now I have gained a certain skill in C++, system design, DSA, multithreading, OOAD,...
I just wonder if I have to learn additional skills or complete more projects and gain enough experience to gain senior level? Btw, Could you share your own path to becoming a senior C++ software engineer?

Flashback: How You Began with C++
If you could restart your journey with the C++ language, what would you avoid, improve, focus less on, dedicate more time to, or learn differently?
Starting with myself:
C++98/03: Focus on mastering memory management principles, especially RAII and the STL, while minimizing reliance on raw pointers and manual resource handling.
C++11/14: Prioritize understanding modern features like move semantics, smart pointers (
std::unique_ptr, std::shared_ptr), and lambda expressions to write more efficient and maintainable code.
C++17/20: Invest time in leveraging features such as structured bindings, `std::optional`, `std::variant`, and `constexpr`, with an emphasis on writing concise and expressive code. Advanced threading and concurrency tools like `std::jthread` and `std::async` would also be key.
C++23/26: Focus on adopting ranges, concepts, std::expected, and std::format to implement type-safe and expressive designs, ensuring better clarity, maintainability, and performance.
Engineering, otherwise: I didn’t think much about architecture back then.
Note: Don’t roast me for the C++98/03 part—I was naïve when I started learning 13 years ago!

Clangd landed "support outgoing calls in call hierarchy" feature which allows for call graph views from IDEs (including VSCode) using clangd
https://github.com/llvm/llvm-project/pull/117673
It's in main so if you have a package repository with the latest llvm you can update clangd-20 and try it out.
Debian:
apt install clangd-20
You may have to set your IDE settings to specifically call clangd-20

what gui liberary do you recommend me to use?
so there are so many libraries for C++ and I'm looking for a good library to create my GUI app and before you say do your own research I did and found many outdated and old libs so I'm looking for a modern GUI library that can be compiled with clang++ bc I want the maximum speed possible I tried wxwwidgets but the tutorials for it is kinda limited and it doesn't work with clang for example this makefile doesn't work unless I replaced clang with g++ and yes I have a clang-mingw compact ``pacman -S mingw-w64-clang-x86_64-gcc-compat``
all:
clang++ -std=c++17 -Werror -O3 -ffast-math \
main.cpp -o runme.exe -Wall -ID:\echo\include -ID:\echo\lib\gcc1320x64dll\mswu \

RFC: I have never thought "unsigned int(eger)" made sense
In programming, why do we call unsigned values "unsigned ints" or "uints"?
Integers are signed by definition. It's a contradiction in terms.
Unsigned values are called the naturals.
Why don't we call them "nats"?
I've added these definitions to my stdfelice.h header, where I fix stuff in C/C++ that I think is stupid:
typedef unsigned int nat;
typedef uint8t nat8t;
typedef uint16t nat16t;
typedef uint32t nat32t;
typedef uint64t nat64t;
typedef uintptrt natptrt;
#define NATMAX UINTMAX
This has the upside that the labels are the same char width as ints! No more ugly unaligned code with mixed signage!
-----
(As an aside, I also define flt, flt32t and flt64t, purely for cosmetic reasons. This is not something I would argue for, though. I'm just mentioning it in passing in case anyone else who's OCD about stuff like function argument lists lining up is interested.)

The HR person caught me cheating!
He said:
"In reviewing your sheet, I am puzzled to see that you used C++98 in jobs from 1994 to 1997, what were you coding on a crystal ball?!!"
They are so smart. Sooooo much.
