If it doesn't happen with the If it still does, run the command in gdb and post the backtrace. |

I've tried also yesterday compiling from rustc-nightly source on my Jolla phone. . |

I also tried to build from git and I got the same output: |

This answers my first question, and from the trace you provided it seems the crash happens very early, probably still in the dynamic loader. That's why I asked you about your Did you try running |

Now you're talking! It's a recent distro with glibc 2.19 - you should be able to try out my stage0 snapshot or some unofficial builds, e.g. Rust 1.8 stable from https://github.com/warricksothr/RustBuild I recommend the stage0 binary first, it has very few dependencies. |
|
Great, let us know if you manage to bootstrap a full rust compiler. (or run one of the unofficial builds) If you do, the issue should be solvable, @japaric will probably have a word or two with the buildbot :) |
|
Today I tried again installing rust with the latest nightly build. But if I try to run rustc, cargo or any other binary I got Segmentation fault. [10140.420203] Pid: 13401, comm: rustc [10140.443154] Pid: 13402, comm: rustc |

You could try some unofficial builds. This one doesn't link in libstdc++ statically: https://www.dropbox.com/s/esfhr8erg8kyhoe/rust-nightly-armv7.tar.xz?dl=0 or one from Rustbuild, built with clang: |

So, your hardware is a Qualcomm Snapdragon MSM8930 SoC - do you know of any quirks/bugs related to vfpv3 or neon it might be affected with? A rebuild of your linux kernel could be necessary. |
|
Yes, It's Jolla Phone (https://en.wikipedia.org/wiki/Jolla_(smartphone), with Qualcomm Snapdragon 400 1.4 GHz dual-core processor. |
|
That kernel is old and probably heavily patched so let's make sure you can't run any rust binaries, ok? Please try a different build from the above links. If nothing works, you'd already confirmed my last stage0 snapshot worked (good for bootstrapping |

|
Yes, I would like to build it, I already tried a few time, but unsuccessfully. |
|
Do you remember why it failed? Provided you were trying to use the snapshot I'd uploaded, did you do something like this? wget https://static.rust-lang.org/dist/rustc-beta-src.tar.gz
tar xvf rustc-beta-src.tar.gz

Yes, I encountered this error in the past too (it means your llvm was compiled with clang, there's an issue about it in this very repo) but it was never addressed. At that time, and I needed to do it just once, I removed that flag from the g++ command line - you can see the full command by running:

Well, this issue is closed, here are no crashes anymore. But no one still has been able to run rustc or cargo inside a target: https://users.rust-lang.org/t/running-rustc-cargo-within-scratchbox2-application-freeze/7879 This prevents anyone from using rust on the phone. |
