CCompilerDriver User Guide
This feature is not supported on the Wolfram Cloud.
The CCompilerDriver package lets you work with C compilers that are installed on your computer. It lets you build executables, libraries, and object files from C source code. It is called automatically by the Wolfram System compiler when you set the option CompilationTarget to "C". It is also useful for building WSTP executables as well as Wolfram Libraries (dynamic linking libraries that can be linked into the Wolfram Language).
