Quick Compile Commands

Prerequisites

On macOS you already have clang/clang++ via Xcode Command Line Tools. For CMake:

brew install cmake

Chapter 1 — First Program (C)

cd chap1/code
gcc firstProgram.cpp -o firstProgram
./firstProgram

Chapter 2 — Header Files Exercise (C)

cd chap2/code
gcc main.c math_operations.c -o program
./program

Multithreading (C++11)

cd Multithreading/code
clang++ -std=c++11 -pthread Multithreading.cpp -o multithreading
./multithreading

Optimization — Loop Unrolling (CMake)

cd Optimization/code
mkdir -p build && cd build
cmake ..
make
./loop_unrolling_example

Virtual Functions Examples (CMake)

Each sub-folder under virtualFunctions/ has its own CMakeLists.txt:

# Example: build the "code" example
cd virtualFunctions/code
mkdir -p build && cd build
cmake ..
make
./notvirt

Available examples:

Folder	Executable
code/	notvirt
codeV2/	notvirt
statfunc/	statfunc
virtpure/	virtpure
virtpers/	virtpers
graphics/	virtshap

Quick one-liner to build any CMake project

cmake -S <source-dir> -B <source-dir>/build && cmake --build <source-dir>/build

Example:

cmake -S virtualFunctions/code -B virtualFunctions/code/build && cmake --build virtualFunctions/code/build
