# Why cant tfclient support XXXXX?

There are limits to what operating systems and architectures tfclient can support. As you may know, tfclient is based upon the [Nebula](https://github.com/slackhq/nebula) project, maintained by Slack. tfclient can only support architectures and operating systems that [Nebula itself supports](https://github.com/slackhq/nebula/releases/).

In addition, tfclient, being written in Rust, can only function in environments [where Rust compiles well](https://doc.rust-lang.org/nightly/rustc/platform-support.html). For example, this rules out MIPS - `rustc` currently does not function correctly on that architecture, and thus tfclient cannot, and likely never will support that architecture.

Did Nebula add a new architecture, and we missed it? Rust supports a new architecture in a new release? [Let us know!](https://lists.e3t.cc/~core/trifid-devel) We love adding support for new systems whenever we can.

Did we miss an architecture? If your architecture is supported by BOTH Nebula and Rust, but you still get `This architecture is not supported yet :(` when trying to build tfclient, we might have missed you - [get in touch](https://lists.e3t.cc/~core/trifid-devel) and we will work with you to get your system supported :D
