The emscripten module will automatically detect the appropriate compilers and set up some architecture-specific items.

When building with Emscripten, additional rules are available to complete the build.

List of Rules

C.emscripten.JSLibraries
C.emscripten.JSPre
C.emscripten.JSPost
C.emscripten.JSExterns

Rules

rule C.emscripten.JSLibraries TARGET : SOURCES : OPTIONS

For the given TARGET, assign libraries via SOURCES to be linked with the link flag –js-library.

Parameters

TARGET	The target to assign the libraries to. `TARGET` is optional if rule ActiveTarget TARGET has been specified. If `TARGET` is `*`, the libraries will be linked for all applications.
SOURCES	The list of libraries.
OPTIONS	If `public` is specified, the libraries specified by `SOURCES` are made available to a project using `C.Inherits`.
