clang++ Command Examples
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
