[Environment Setup 8] Compile programs from source code using GCC, GNU Make, and CMake

Create a file named main.cpp

$ touch main.cpp

Compile the file using gcc c++ compiler

$ g++ main.cpp

Run the compiled executable

$ ./a.out

Remove the executable

$ rm a.out

Compile the source file with the output name main

$ g++ main.cpp -o main

Run the new executable

$ ./main

Create two new files helpers.cpp and helpers.h

$ touch helpers.cpp

$ touch helpers.h

Compile multiple source files

$ g++ main.cpp helpers.cpp -o main

Just compile (and not link) individual source files

$ g++ -c main.cpp

$ g++ -c helpers.cpp

Link the compiled object files into the final executable

$ g++ main.o helpers.o -o main

Remove object files

$ rm *.o

Remove the executable

$ rm main

Create the Makefile for GNU Make

$ touch Makefile

Run GNU Make to build the program

$ make

Remove compiled object and executable

$ make clean

Create the input file of CMake

$ touch CMakeLists.txt

Check CMake version

$ cmake --version

Create a directory named build

$ mkdir build

Nvigate to build directory

$ cd build/

Call CMake to generate the Makefile

$ cmake ..

Build the program using GNU Make

$ make
