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}} -I{{path/to/header_path}} -L{{path/to/library_path}} -l{{path/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}} -O{{1|2|3|fast}} {{-o|--output}} {{path/to/output_executable}}

• Display version:

clang++ --version
