# 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`
|
