Compiles C++ source files. Part of LLVM. More information: <https://clang.llvm.org>.

  • Compile a source code file into an executable binary:
    clang++ path/to/source.cpp -o path/to/output_executable
  • Display (almost) all errors and warnings:
    clang++ path/to/source.cpp -Wall -o path/to/output_executable
  • Choose a language standard to compile with:
    clang++ path/to/source.cpp -std=c++20 -o path/to/output_executable
  • Include libraries located at a different path than the source file:
    clang++ path/to/source.cpp -o path/to/output_executable -Ipath/to/header_path -Lpath/to/library_path -lpath/to/library_name
  • Compile source code into LLVM Intermediate Representation (IR):
    clang++ -S -emit-llvm path/to/source.cpp -o path/to/output.ll
  • Optimize the compiled program for performance:
    clang++ path/to/source.cpp -O1|2|3|fast -o path/to/output_executable
