| # AllN |
| |
| > TODO(fxbug.dev/3367): delete this directory. |
| |
| This directory contains transient build infrastructure used for the AllN effort |
| which aims at producing a single GN/ninja build for the entire Fuchsia system. |
| |
| The `zn_build` directory hosts build templates that are sneakily inserted into |
| `//zircon/*/BUILD.gn` files so that they integrate with the Fuchsia GN build. |
| |
| ## Zircon library mappings |
| |
| The `zircon_library_mappings.json` file configures some forwarding targets |
| installed under `//zircon/public/lib` to assist with the migration of libraries. |
| |
| Entries in this file should be added to the top-level array with the following |
| format: |
| ``` |
| { |
| "name": "foobarblah", |
| "label": "//zircon/system/ulib/halbraboof", |
| "sdk": true |
| } |
| ``` |
| |
| All attributes are required: |
| - `name` is the name of the forwarding target under `//zircon/public/lib`; |
| - `label` is the GN label of the library the target should forward to; |
| - `sdk` controls whether an additional forwarding target should be set up for |
| the library. |
| |
| To use this data in GN, import `zircon_library_mappings.gni`. The source of |
| truth is a JSON file so that it may easily be read by the Python script |
| generating the mappings (`//build/zircon/populate_zircon_public.py`). |
