| # libgps |
| |
| Bazel overlay for [gpsd](https://gpsd.io/) `libgps`. |
| |
| ## Overlay Files |
| |
| The overlay adds a hand-authored `include/gpsd_config.h` because upstream |
| generates this header from SCons configuration checks before compiling |
| `libgps`. |
| |
| When bumping libgps to a newer gpsd release: |
| |
| 1. Compare upstream `SConstruct` and `SConscript` configuration checks with the |
| defines in `overlay/include/gpsd_config.h`. |
| 2. Update `overlay/include/gpsd_config.h` for changed version constants, |
| protocol constants, feature checks, and platform-specific defines. |
| 3. Run `bazel run //tools:update_integrity` after modifying overlay files. |
| 4. Verify the targets listed in `modules/libgps/<version>/presubmit.yml`. |
| |
| The generated `ais_json.i` and `libgps/gps_maskdump.c` files are produced by |
| Bazel during the build and are not checked into the overlay. |
