gcc

• Compile multiple source files into an executable: gcc {{path/to/source1.c path/to/source2.c ...}} -o {{path/to/output_executable}}

• Show common warnings, debug symbols in output, and optimize without affecting debugging: gcc {{path/to/source.c}} -Wall -g -Og -o {{path/to/output_executable}}

• Include libraries from a different path: gcc {{path/to/source.c}} -o {{path/to/output_executable}} -I{{path/to/header}} -L{{path/to/library}} -l{{library_name}}

• Compile source code into Assembler instructions: gcc -S {{path/to/source.c}}

• Compile source code into an object file without linking: gcc -c {{path/to/source.c}}

• Optimize the compiled program for performance: gcc {{path/to/source.c}} -O{{1|2|3|fast}} -o {{path/to/output_executable}}
