|
|||
- `libpq`, which is needed for applications that use `diesel` with PostgreSQL. Note that this may be broken under Rust 1.21.0 and later (see https://github.com/emk/rust-musl-builder/issues/27).
|
||||
- `libz`, which is needed by `libpq`.
|

|

You can also use the following libraries with a bit of setup:
|
||||
|
||||
- SQLite3 with
|
||||
`diesel`. See [examples/using-diesel](./examples/using-diesel/).
|
||||
|
||||
This library also sets up the environment variables needed to compile popular Rust crates using these libraries.
