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