g++

Compile C++ source files. Part of GCC (GNU Compiler Collection). More information: https://gcc.gnu.org.

• Compile a source code file into an executable binary:

g++ path/to/source1.cpp path/to/source2.cpp … -o|–output path/to/output_executable

• Activate output of all errors and warnings:

g++ path/to/source.cpp -Wall -o|–output output_executable

• Show common warnings, debug symbols in output, and optimize without affecting debugging:

g++ path/to/source.cpp -Wall -g|–debug -Og -o|–output 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|–output path/to/output_executable

• Include libraries located at a different path than the source file:

g++ path/to/source.cpp -o|–output 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|–compile path/to/source1.cpp path/to/source2.cpp … && g++ -o|–output path/to/output_executable path/to/source1.o path/to/source2.o …

• Optimize the compiled program for performance:

g++ path/to/source.cpp -O1|2|3|fast -o|–output path/to/output_executable

• Display version:

g++ --version
