compiles a string of C code and creates a library file, name.ext.


compiles a number of C source files and creates a library file, name.ext.


  • To use CreateLibrary, you first need to load it using Needs["CCompilerDriver`"].
  • If the first argument is a string, CreateLibrary treats it as C code. If the first argument is a list of one or more strings, it is treated as a list of files that contain C code.
  • If CreateLibrary cannot find a suitable C compiler, it issues a message and returns $Failed.
  • The extension given to the library depends on the platform for which the library is created.
  • The following options can be given:
  • "CleanIntermediate"Automaticwhether temporary files should be deleted
    "CompileOptions"""options to pass through to the compiler
    "Compiler"Automaticthe compiler to use
    "CompilerInstallation"Automaticlocation of the compiler software
    "CompilerName"Automaticwhich compile command to use
    "CreateBinary"Truewhether the library file should be created
    "Debug"Falsecompiles with debug information, does not clean the intermediate output, and prints the compile commands and output
    "Defines"{}C preprocessor defines to use for the build
    "ExtraObjectFiles"{}previously compiled object files to include in the executable
    "IncludeDirectories"{}directories to add to the include path
    "Language"Automaticwhat language the source code is in (can be used to assume source is C or C++ rather than relying on automatic detection)
    "Libraries"{}libraries to use to build the executable
    "LibraryDirectories"{}directories to add to the library lookup path
    "LinkerOptions"{}options passed to the linker
    "PostCompileCommands"""shell commands to run after compilation
    "PreCompileCommands"""shell commands to run before compilation
    "ShellCommandFunction"Nonefunction to call with the shell commands used for compilation
    "ShellOutputFunction"Nonefunction to call with the shell output of running the compilation commands
    "SystemCompileOptions"{}options to pass through to the compiler before "CompileOptions"
    "SystemIncludeDirectories"Automaticdirectories to locate Wolfram Language header files
    "SystemLibraries"AutomaticWolfram Language libraries
    "SystemLibraryDirectories"Automaticdirectories to locate Wolfram Language libraries
    "SystemLinkerOptions"{}options passed to the linker before "LinkerOptions"
    "TargetDirectory"Automaticthe directory in which the executable file should be created
    "TargetSystemID"$SystemIDthe system for which output should be generated
    "TransferProtocolLibrary"Automaticwhich link library (WSTP or MathLink) to use
    "WorkingDirectory"Automaticthe directory in which temporary files should be generated
  • The "CleanIntermediate" option can take one of four settings. Automatic, the default, removes all intermediate files except on Windows, where the .exp and .lib files are preserved since they are needed when compiling files using the library. True removes all intermediate files. False preserves all intermediate files. Full indiscriminately removes all files in the working directory whether they are intermediate files or not.


Basic Examples  (1)

First, load the package:

This is the source of a library:

This creates a library:

Now, the library is loaded with LibraryFunctionLoad:

Here a function from the library is called:
