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 -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
