LoadCompiledComponent[comp]

loads a compiled component comp.

LoadCompiledComponent[comp,target]

loads a compiled component comp from the target location.

Details

  • Compiled components can be used to represent a named group of compiler declarations.
  • Compiled components can be used to represent compiled functionality that can be built into a shared library.
  • Compiled components can be embedded in paclets.
  • comp can be given as a CompiledComponent object or a string with the name of a compiled component.
  • Typically, loading a compiled component involves loading a shared library created with BuildCompiledComponent.
  • If no target location is given, then FindLibrary is used to find a library with the same name as the target component.
  • The "ExternalLibraries" setting of DeclareCompiledComponent gives external libraries that are loaded before the component library is loaded.
  • The "LoadingEpilogs" setting of DeclareCompiledComponent gives functions to be executed after the component library is loaded.
  • Calling an installed function from an unloaded component will attempt to automatically load the component, failing if no build exists.
  • The following option can be given:
  • CompilerEnvironmentAutomatica compiler environment, which by default includes the declarations in the component, passed to functions set by "LoadingEpilogs"

Basic Examples  (1)

Create a compiled component:

Wolfram Language code: DeclareCompiledComponent["demoComp", "LibraryFunctions" -> <| "square" -> Function[{Typed[arg, "Real64"]}, arg ^ 2] |>];

Build the component:

Wolfram Language code: BuildCompiledComponent["demoComp"]

Load the component:

Wolfram Language code: res = LoadCompiledComponent["demoComp"]

Call the function included in the built component:

Wolfram Language code: res["LibraryFunctions"]["square"][10.5]

Scope  (1)

Declare a list of declarations in a component:

Wolfram Language code: DeclareCompiledComponent["fullComponent", { FunctionDeclaration[return12, Typed[{} -> "MachineInteger"]@Function[{}, 12]], FunctionDeclaration[addtwo, Typed[{"MachineInteger"} -> "MachineInteger"]@Function[x, x + 2]] }];

Declare a library function:

Wolfram Language code: DeclareCompiledComponent["fullComponent", "LibraryFunctions" -> <| "libFunc" -> Function[Typed[arg, "Real64"], Sqrt[arg]] |>];

Declare an installed function:

Wolfram Language code: DeclareCompiledComponent["fullComponent", "InstalledFunctions" -> addtwo];
Wolfram Language code: BuildCompiledComponent["fullComponent"]

Use an installed function to automatically load the build:

Wolfram Language code: addtwo[3]

Explicitly load the component to access the built library function:

Wolfram Language code: LoadCompiledComponent["fullComponent"]
