If it doesn't happen with the arm- triple (instead of armv7), the ARM part you're running this on probably doesn't have NEON. (Thumb2?)

If it still does, run the command in gdb and post the backtrace.

MagaTailor commented 8 years ago

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 glibc version and GNU Linux binaries compatibility. You can throw in other libraries's versions and your gcc -v.

Did you try running cargo?

MagaTailor commented 8 years ago

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.

corvinux commented 8 years ago

@petevine Thanks for help, your stage0, works. :+1:

MagaTailor commented 8 years ago

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 :)

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.

corvinux commented 8 years ago

Yes, It's Jolla Phone (https://en.wikipedia.org/wiki/Jolla_(smartphone), with Qualcomm Snapdragon 400 1.4 GHz dual-core processor. uname -a Linux Jolla 3.4.108.20150901.1 #1 SMP PREEMPT Sun Apr 24 12:19:33 UTC 2016 armv7l armv7l armv7l GNU/Linux

MagaTailor commented 8 years ago

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 rust 1.10 but not nightly any more) so if you already had llvm installed it would take about 5-6h to build your own rustc. Let me know if you want to try it and need a few pointers.

corvinux commented 8 years ago

Yes, I would like to build it, I already tried a few time, but unsuccessfully.

MagaTailor commented 8 years ago

Do you remember why it failed?

Provided you were trying to use the snapshot I'd uploaded, did you do something like this? The rustc snapshot should be found in /tmp/bin and your LLVM installation in /usr.

wget  https://static.rust-lang.org/dist/rustc-beta-src.tar.gz
tar xvf rustc-beta-src.tar.gz
cd rustc-beta
./configure --enable-optimize --disable-jemalloc --llvm-root=/usr --disable-docs --enable-local-rust --local-rust-root=/tmp --prefix=~/rust-beta-1.10 --build=armv7-unknown-linux-gnueabihf
make -j2
make install

If you don't have LLVM installed, remove --llvm-root=/usr but be prepared to wait another 8h :( @

corvinux commented 8 years ago

It always failed as I mentioned in earlier posts like this

@corvinux Glad you can try rust out, however there's a misunderstanding here:

It always failed as I mentioned in earlier posts like this

rustc: arm-unknown-linux-gnueabihf/stage0/lib/rustlib/arm-unknown-linux-gnueabihf/lib/libcore

Those were the official rust binaries which for some reason crash on your system. The ones that work, including the stage0 snapshot that you didn't use in the end, were built natively on my ARM Linux system (without NEON). And that's the whole issue.

You could try the other links (e.g rustc built with NEON) or you can try bootstrapping your own rustc using the commands I gave you. (use my snapshot, put the rustc binary in /tmp/bin, etc)

@corvinux If you don't have FileCheck installed, adding --disable-codegen-tests to the configure command line should help.

It's true rust bootstrap process is a little convoluted but you're still not following my instructions so it would fail anyway! You need to use the working snapshot and build the 1.10-beta source (a working 1.10-beta rustc would allow you to bootstrap the nightly compiler).

MagaTailor commented 8 years ago

Oh, and if rustc 1.11.0-nightly (12238b9 2016-06-04) that you installed in /usr/local is working for you, where did you get it from?

corvinux commented 8 years ago

@petevine rustc 1.11.0-nightly (12238b9 2016-06-04) was probably my attempt to do cross-compiling on my X86_64 Debian Rolling machine. Today I tried to build rust on my Jolla Phone on which I have working, as I mention in some previous post, rustc 1.11.0-dev (623af22 2016-05-28) from your link https://www.dropbox.com/s/esfhr8erg8kyhoe/rust-nightly-armv7.tar.xz?dl=0, following your instructions: [root@Jolla rustc-beta]# ./configure --enable-optimize --disable-jemalloc --llvm-root=/usr/local --disable-codegen-tests --disable-docs --enable-local-rust --local-rust-root=/usr/local --prefix=~/rust-beta-1.10 --build=armv7-unknown-linux-gnueabihf And I got this error: compile: armv7-unknown-linux-gnueabihf/rustllvm/ExecutionEngineWrapper.o g++: error: unrecognized command line option '-Wcovered-switch-default' make: * [armv7-unknown-linux-gnueabihf/rustllvm/ExecutionEngineWrapper.o] Error 1 make: * Waiting for unfinished jobs.... make: * wait: No child processes.

MagaTailor commented 8 years ago

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:

VERBOSE=1 make.

Let me repeat; to successfully build the 1.10-beta, you need to use the older snapshot and not the latest nightly!

MagaTailor commented 8 years ago

@corvinux I can see you've got clanginstalled so the quickest solution to the above problem would be to use it instead of gcc. Add --enable-clang to the configure command line.

It seems the correct snapshot is being used and it even managed to compile a few crates but you're still using g++. I suggest deleting the build directory (armv7-unknown-linux-gnueabihf) and running configure again with --enable-clang.

MagaTailor commented 8 years ago

Maybe --enable-clang is buggy or doesn't cover the llvm wrapper compilation and CC/CXX variables need to be set explicitly. Try running like this:

$ CC=clang CXX=clang++ ./configure ...

If that doesn't help, I'll post a workaround.

corvinux commented 8 years ago

@petevine I tried, but no luck! I have also tried with downgrade gcc (Linaro GCC 4.8-2014.01) 4.8.3 20140106 (Mer 4.8.3-1), before I was using gcc 5.2.

CC=clang CXX=clang++ ./configure --enable-clang --enable-optimize --disable-docs --llvm-root=/usr/local --enable-local-rust --local-rust-root=/root/tmp --disable-codegen-tests --prefix=~/rust-beta-1.10 --build=armv7-unknown-linux-gnueabihf

All ouput http://paste2.org/VUE8Ip0y

MagaTailor commented 8 years ago

The error is not related to the gcc version but a switch specific to clang that's injected from llvm-config --cflags. Alright, here's a solution that should work without any future manual work.

Rename your llvm-config to llvm-config.orig and put the following in your new llvm-config (make it executable with chmod +x):

/usr/local/bin/llvm-config.orig "$@" | sed s/-Wcovered-switch-default//

Now it should start working with g++. I expect a success story this time! ;)

You probably didn't move your llvm directory around so it shouldn't happen. To see which include paths are being used, please add verbose output from that last command and let's ask @brson for help.

@corvinux You could also add output from llvm-config --includedir

@corvinux We'll need the last part from VERBOSE=1 make. Could you confirm /usr/local/include/llvm/IR/IRBuilder.h's presence?

OK, as promised, the llvm wrapper compiles fine now. @corvinux Please, just type VERBOSE=1 make without running configure again and show us the last part.

EDIT: Oh, it's probably just python not liking the llvm-config wrapper script. Please put the original back in place, run make and it should probably be OK.

Strange, maybe it was necessary to touch the four .o files in rustllvm first. Try that before anything else and ask for a permanent solution here.

If you're really motivated to see the bootstrap process finish, try copy/pasting the 4 commands minus -Wcovered-switch-default - the first one:

@corvinux To fix the llvm-config wrapper problem add #!/bin/bash to it on the first line. This will keep python (mklldeps.py) happy. 

#!/bin/bash

MagaTailor commented 8 years ago

You should be able to use gcc/g++ without a problem now, --enable-clang can be skipped. If that's not enough, however, you could also try --disable-libcpp or install libc++.
