  • Compile a source code file into an executable binary:
    clang input_source.c -o output_executable
  • Activate output of all errors and warnings:
    clang input_source.c -Wall -o output_executable
  • Include libraries located at a different path than the source file:
    clang input_source.c -o output_executable -Iheader_path -Llibrary_path -llibrary_name
  • Compile source code into LLVM Intermediate Representation (IR):
    clang -S -emit-llvm file.c -o file.ll
  • Compile source code without linking:
    clang -c input_source.c
  • Optimize the compiled program for performance:
    clang path/to/source.c -O1|2|3|fast
