# clang
|
||
|
|
|
||
|
|
> Compile C, C++, and Objective-C source files. Can be used as a drop-in replacement for GCC.
|
||
|
|
> Part of LLVM.
|
||
|
|
> More information: <https://clang.llvm.org/docs/ClangCommandLineReference.html>.
|

|
|
|
||
|
|
- Compile multiple source files into an executable:
|
||
|
|
|
||
|
|
`clang {{path/to/source1.c path/to/source2.c ...}} {{-o|--output}} {{path/to/output_executable}}`
|
||
|
|
|
||
|
|
- Activate output of all errors and warnings:
|
||
|
|
|
||
|
|
`clang {{path/to/source.c}} -Wall {{-o|--output}} {{output_executable}}`
|
||
|
|
|
||
|
|
- Show common warnings, debug symbols in output, and optimize without affecting debugging:
|
||
|
|
|
||
|
|
`clang {{path/to/source.c}} -Wall {{-g|--debug}} -Og {{-o|--output}} {{path/to/output_executable}}`
|
||
|
|
|
||
|
|
- Include libraries from a different path:
|
||
|
|
|
||
|
|
`clang {{path/to/source.c}} {{-o|--output}} {{path/to/output_executable}} -I{{path/to/header}} -L{{path/to/library}} -l{{library_name}}`
|
||
|
|
|
||
|
|
- Compile source code into LLVM Intermediate Representation (IR):
|
||
|
|
|
||
|
|
`clang {{-S|--assemble}} -emit-llvm {{path/to/source.c}} {{-o|--output}} {{path/to/output.ll}}`
|
||
|
|
|
||
|
|
- Compile source code into an object file without linking:
|
||
|
|
|
||
|
|
`clang {{-c|--compile}} {{path/to/source.c}}`
|
||
|
|
|
||
|
|
- Optimize the compiled program for performance:
|
||
|
|
|
||
|
|
`clang {{path/to/source.c}} -O{{1|2|3|fast}} {{-o|--output}} {{path/to/output_executable}}`
|
||
|
|
|
||
|
|
- Display version:
|
||
|
|
|
||
|
|
`clang --version`
|
