gcc: preprocess and compile C and C++ source files, then assemble and link them together

What is gcc ? 🔗

Preprocess and compile C and C++ source files, then assemble and link them together. Part of GCC (GNU Compiler Collection).

Usage 🔗

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 -Ipath/to/header -Lpath/to/library -llibrary_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 -O1|2|3|fast [-o|--output] path/to/output_executable

Display version:

gcc --version
