Unable to compile

[luizsol]

Hi everyone.

I'm currently using tds and tds_encoding on my project and I'm having problems compiling this library:

$ mix compile
Compiling NIF crate :tds_encoding (native/tds_encoding)...
   Compiling rustler_sys v2.0.0
   Compiling rustler v0.21.0
error: failed to run custom build command for `rustler_sys v2.0.0`

Caused by:

I suspect that by bumping the rustler dependency to 0.21.1 the problem may be solved.

Here's my elixir version:

Erlang/OTP 24 [erts-12.0] [source] [64-bit] [smp:32:32] [ds:32:32:10] [async-threads:1] [jit]

Elixir 1.11.3 (compiled with Erlang/OTP 23)

Hi @luizsol
This is probably due to missing rebar3 support in rustler there is still no official workaround that works for all OS-es (Win, linux and MacOS) I see some effort here to support MacOS.

This has nothing to do with rebar3. The tds_encoding crate needs to be updated to a newer rustler version to support the newer NIF version of OTP24. See rusterlium/rustler#359.
