|
|
|
|
- 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}}`
