[rust-dev] RFC: Future of the Build System

rustc is "just" another regular Rust application. So use the tools that
any other Rust application (will) use ;-)
I think at some point in time there will be a capable build tool written
in Rust (like there is for all the other languages). Then it would make
sense to switch using it for the compiler as well.

Therefore the decisional weight of choosing a non - rust based solution over a rust one because Debian packagers have problems packaging a compiler is not adequately justified.
> Using a well known build system as a means to appeal to programmers is seemingly an advantage, but it does not exonerate them from having to be competent in Rust before they write useful programs. And that has a learning curve superior to that of a build system.
> As for boost's jam I have nothing to say other than boost having its own build system makes it easy for boost first; this does not mean that their needs are those of everybody else and boost is a library, not a programming language itself. So, again, a decision based on picking a popular solution on the basis of such a comparison, has flawed background.
> Lastly, imagine the irony of Rust proposing to use python, c, c++ based build tools for simple packages. That would make packagers more frustrated because of a wider set of dependecies. While end users would have to also deal with a known system, its eventual inadequacies could not be met directly by Rust devs unless they start amending that system in order to deal with them. Therefore, maintenance overhead is inescapable either way, with the pessimization of relying in another nom - Rust project in order to make it worth your while to enjoy programming in Rust.
> The only valid argument against having a build system proposed as the official, defacto, cross - platform way of building rust packages written in rust is its development and maintenance overhead for the rust core team itself.
> That problem is easily circumvented by not proposing one right now and letting it to the end developer decide. If however an official build system is to be proposed, Rust developers merit having it done on their own platform, thus proving rust's worth. It is 2014 after all.
