IP-retrieve-cpp

A try out cpp program (retrieve IP address) to show cpp development using clang(for myself)¹

Standard Library

TODO: NEED TO COMFIRM

I installed Visual Studio beforehand so library (like <iostream>) may come with MSCV

The C++ standard library is typically provided as a separate package from the compiler, and LLVM is a compiler infrastructure, not a compiler itself. In other words, LLVM(clang) does not include a C++ standard library.

Compile/Build

We will be using CMake for building our program and Ninja as the build generator

Generate build files: cmake -S . -B build -G Ninja [-DCMAKE_BUILD_TYPE=Release] [--fresh]²
Build the program(executable): cmake --build build [--clean-first]³

To remove build files and executable, you can just delete those directories rm -rf build/ bin/

Inside [] is the option flag that can put in command line
Use VSCode extension to skip all the command lines typing

Run

./bin/ip-retrieve.exe input.txt

Footnotes

1. For easy workflow, might as well just download visual studio and build using that ↩

2. -DCMAKE_BUILD_TYPE=Release: Ninja generate default build type is debug (or because is GNU like)
   --fresh: is the re-generate the build files ↩

3. --clean-first will clean the bin before generating the executable program or run with --target clean to just clean (only clean based on the build files) ↩
