gcc

Preprocess and compile C and C++ source files, then assemble and link them together. Part of GCC (GNU Compiler Collection). More information: https://gcc.gnu.org.

• Compile multiple source files into an executable:

gcc {{path/to/source1.c path/to/source2.c ...}} {{-o|--output}} {{path/to/output_executable}}

• Activate output of all errors and warnings:

gcc {{path/to/source.c}} -Wall {{-o|--output}} {{output_executable}}

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

gcc {{path/to/source.c}} -Wall {{-g|--debug}} -Og {{-o|--output}} {{path/to/output_executable}}

• Include libraries from a different path:

gcc {{path/to/source.c}} {{-o|--output}} {{path/to/output_executable}} -I{{path/to/header}} -L{{path/to/library}} -l{{library_name}}

• Compile source code into Assembler instructions:

gcc {{-S|--assemble}} {{path/to/source.c}}

• Compile source code into an object file without linking:

gcc {{-c|--compile}} {{path/to/source.c}}

• Optimize the compiled program for performance:

gcc {{path/to/source.c}} -O{{1|2|3|fast}} {{-o|--output}} {{path/to/output_executable}}

• Display version:

gcc --version
