psp2-sys's Issues

Status of this org and rust std on vita

Hi,

In the last couple of weeks, I have managed to compile rust std for ps vita (via vitasdk newlib).

I have made PR's to rust-lang/libc, rust-lang/backtrace-rs, rust-random/rand, and of course rust-lang/rust. Also I made some contributions to glium and vitagl in order to make them work together. As of writing this, all of my PR's but the std itself are merged, and rust-lang/rust PR is approved, and will probably be merged soon.

Unfortunately, I don't have the capacity to test the whole scope of std, but a couple of things I've tested:

• Allocations work (e.g. Vec)
• Concurrency primitives work (atomics, mutexes, etc.)
• Random works (e.g. HashMap)
• rust-sdl2 works
• Attempts of backtrace unwinding crash real hardware, and go into an infinite allocation loop on an emulator
• FS access should mostly work
• Networking is uncharted territory for now. I've tried building reqwest, but it depends on some of the tokio stuff, requiring unix sockets and select API, not sure if it would be possible to port that.

It would be amazing if there were other people willing to work on that/support that effort.
So, my question is, what's the status of this org? I think it would be nice to have some guides and examples for rust+std+vita stuff in this org.

I can't run hello_rust_world.

Environment

• vitasdk version: vitasdk-x86_64-apple-darwin-2018-09-02_17-59-26.tar.bz2
• os version: macOS 10.13.6
• rustc version: 1.32.0-nightly (f1e2fa8f0 2018-11-20)
• xargo version: 0.3.12
• cargo version: 1.32.0-nightly (b3d0b2e54 2018-11-15)
