A Short Note About Mojo

Mojo is defined as “a collection of runtime libraries that provide a platform-agnostic abstraction of common IPC primitives, a message IDL format, and bindings library with code generation for multiple target languages to facilitate convenient message passing across arbitrary inter- and intra-process boundaries.

To run high-level support libraries, including the System APIs or Binding APIs, you must initialize Mojo Core first. Some platforms also enable applications to depend on a dynamically linked Mojo Core library. To benefit from this, the library’s binary should be present in one of the following.

  • The working directory of the application
  • A directory named by the MOJO_CORE_LIBRARY_PATH environment variable
  • A directory named at the run time explicitly by the application.
