Is this still operational? #17

Closed hgrecco closed 8 years ago

hgrecco commented 8 years ago

The lastest build seems to be 1.8 nightly. are you planning to update?

MagaTailor commented 8 years ago

You can still find up-to-date builds here:

https://sothr.com/RustBuild/armv6-armhf/rust/nightly/latest

The only practical inconvenience is going to come from having to pass -C target-cpu and -C target-feature flags when targeting armv7. You don't have to worry about performance hit from using v6 rustlibs.

If you do, however, you can pass --target=armv7-unknown-linux-gnueabihf to rustc instead, after installing matching armv7- crates.

Lastly, it seems ARM binaries are going to be officially distributed soon.

I have some build issues on the armv7 versions and I haven't had the time to debug the build system. The armv6 builds still work and are what I've been using locally till I get a chance to rebuild the armv7 build system and debug the issue.

Built a new version of ARMv7 rust manually. Making the changes to the builder and closing this after I test it and cargo on the odroid. Would appreciate if you're interested that you test the latest ARMv7 build as well.

Cargo is having some issues with the static ssl configuration patch. Looking into that now.

Going to close this and update the Readme to point to the latest dropbox folders after stable and beta build tonight.

@warricksothr Yeah, works like a charm. BTW, compared to the official distribution, you should advertise the distinguishing feature of your builds, namely, relying on system allocation instead of jemalloc. On an untested platform like ARM (for both rust and jemalloc) it's a boon.

As for performance, you could try running the binary_trees benchmark on your Cortex-A15 based board - on weaker ARM parts there's no benefit from jemalloc but that particular one might show some.

Lastly, that ARM patch, I always build with, will make it into LLVM for the 3.8.1 release which means official rust performance on ARM will have to suffer for a bit longer.
