Description
The CMake and Meson build definitions are maintained separately and have drifted. On current main (e0399c6945326dd5281da07de8ed14a61c9f2cac), equivalent configurations do not install the same public headers or run the same core tests.
Examples:
-
CMake installs public headers by globbing each directory, while Meson lists them manually. As a result:
- CMake installs
iceberg/puffin_dv_io.h and iceberg/catalog/rest/auth/token_refresh_scheduler.h, but Meson does not.
- Meson installs
iceberg/catalog/catalog_util.h, iceberg/catalog/session_catalog.h, and iceberg/catalog/session_context.h, but CMake does not install headers from src/iceberg/catalog/.
-
CMake includes snapshot_summary_builder_test.cc in table_test, but Meson does not include that test source, so the Meson CI path does not exercise it.
-
Vendored/fallback dependency versions differ between the two build systems:
| Dependency |
CMake |
Meson |
| CRoaring |
4.4.3 |
4.3.11 |
| nlohmann/json |
3.11.3 |
3.12.0 |
| GoogleTest |
1.15.2 |
1.17.0 |
Other shared dependencies, such as nanoarrow 0.9.0, utf8proc 2.10.0, spdlog 1.15.3, cpr 1.14.1, and Google Benchmark 1.8.4, are currently aligned but can drift because their pins are also declared independently.
-
Dependency resolution policy also differs: CMake requires system Zlib and Curl, while Meson can fall back to pinned wraps (Zlib 1.3.1 and Curl 8.10.1). Any intentional difference here should be documented and tested explicitly.
The Meson bundle gap is already tracked by #256 and is outside the scope of this issue. Other intentional feature differences should likewise remain explicit rather than appearing as accidental drift.
