clang++

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

• Compile a set of source code files into an executable binary:

clang++ path/to/source1.cpp path/to/source2.cpp … -o|–output path/to/output_executable

• Activate output of all errors and warnings:

clang++ path/to/source.cpp -Wall -o|–output output_executable

• Show common warnings, debug symbols in output, and optimize without affecting debugging:

clang++ path/to/source.cpp -Wall -g|–debug -Og -o|–output path/to/output_executable

• Choose a language standard to compile for:

clang++ path/to/source.cpp -std=c++20 -o|–output path/to/output_executable

• Include libraries located at a different path than the source file:

clang++ path/to/source.cpp -o|–output 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|–assemble -emit-llvm path/to/source.cpp -o|–output path/to/output.ll

• Optimize the compiled program for performance:

clang++ path/to/source.cpp -O1|2|3|fast -o|–output path/to/output_executable

• Display version:

clang++ --version
