  • Compile a source code file into an executable binary:
    g++ path/to/source.cpp -o path/to/output_executable
  • Display common warnings:
    g++ path/to/source.cpp -Wall -o path/to/output_executable
  • Choose a language standard to compile for (C++98/C++11/C++14/C++17):
    g++ path/to/source.cpp -std=c++98|c++11|c++14|c++17 -o path/to/output_executable
  • Include libraries located at a different path than the source file:
    g++ path/to/source.cpp -o path/to/output_executable -Ipath/to/header -Lpath/to/library -llibrary_name
  • Compile and link multiple source code files into an executable binary:
    g++ -c path/to/source_1.cpp path/to/source_2.cpp ... && g++ -o path/to/output_executable path/to/source_1.o path/to/source_2.o ...
  • Optimize the compiled program for performance:
    g++ path/to/source.cpp -O1|2|3|fast -o path/to/output_executable
  • Display version:
    g++ --version
