Here's an infrequently-asked-questions list about fixing some common (and

not-so-common) issues in your Arti compilation or usage.

## Compilation issues
|
|
|
|
|
|
|
|
|
|
### When I try to build Arti, linking fails!
|
|
|
|
|
|
|
|
|
|
Arti uses your system's sqlite3 and TLS libraries. Make sure that you have
|
|
|
|
|
development libraries for sqlite3 installed. You might also need to install
|
|
|
|
|
the development libraries for OpenSSL, if you aren't on Windows or OSX.
|

|
|
|
You may also need to install `pkg-config`.
|
|
|
|
|
|
|
|
|
|
#### In more detail...
|
|
|
|
|
|
|
|
|
|
We use sqlite3 via the `rusqlite` crate. Our TLS implementation is the
|
|
|
|
|
`native_tls` crate, which relies on `security-framework` (on OSX),
|
|
|
|
|
`schannel` (on Windows), or `openssl` (elsewhere).
|
|
|
|
|
|
|
|
|
|
Both of these crates, by default, access their dependencies via
|
|
|
|
|
`pkg-config` or `vpkg` as appropriate. But you can override this
|
|
|
|
|
behavior if you run into trouble:
|
|
|
|
|
|
|
|
|
|
* You can build `arti` or `arti-client` with the `static` feature, and
|
|
|
|
|
the underlying crates will be told to build their own dependencies
|
|
|
|
|
from source and link statically.
|
|
|
|
|
|
|
|
|
|
* For more information on building `rusqlite` in different
|
|
|
|
|
environments, see [this section of their README](https://github.com/rusqlite/rusqlite#notes-on-building-rusqlite-and-libsqlite3-sys).
|
|
|
|
|
|
|
|
|
|
* For more information on building the `openssl` crate in different
|
|
|
|
|
environments, see the
|
|
|
|
|
["building" section](https://docs.rs/openssl/latest/openssl/#building)
|
|
|
|
|
of their documentation.

### I get a weird segfault on startup on Alpine Linux!
|
|
|
|
|
|
|
|
|
|
If you're seeing this kind of error from inside the native_tls crate
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
arti[62370]: segfault at 0 ip 0000000000000000 sp 00007fff9fa01128 error 14
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
then you might be hitting a
|
|
|
|
|
[known issue](https://githubmemory.com/repo/sfackler/rust-native-tls/issues/190)
|
|
|
|
|
on native_tls on Alpine linux.
|
|
|
|
|
|
|
|
|
|
You can solve this by building with `RUSTFLAGS=-Ctarget-feature=-crt-static`.
