# 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`
