12 # Native libraries built as part of the rust build process
14 # This portion of the rust build system is meant to keep track of native
15 # dependencies and how to build them. It is currently required that all native
16 # dependencies are built as static libraries, as slinging around dynamic
17 # libraries isn't exactly the most fun thing to do.
19 # This section should need minimal modification to add new libraries. The
20 # relevant variables are:
23 # This is a list of all native libraries which are built as part of the
24 # build process. It will build all libraries into RT_OUTPUT_DIR with the
25 # appropriate name of static library as dictated by the target platform
28 # This is a list of files relative to the src/rt directory which are
29 # needed to build the native library. Each file will be compiled to an
30 # object file, and then all the object files will be assembled into an
31 # archive (static library). The list contains files of any extension
33 # If adding a new library, you should update the NATIVE_LIBS list, and then list
34 # the required files below it. The list of required files is a list of files
35 # that's per-target so you're allowed to conditionally add files based on the
