Preprocess and compile C and C++ source files, then assemble and link them together. More information:

  • 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}}
