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}} -I{{path/to/header}} -L{{path/to/library}} -l{{library_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}} -O{{1|2|3|fast}} {{-o|--output}} {{path/to/output_executable}}

• Display version:

g++ --version
