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.

Two questions:

  • did you install the other ARM distribution (arm-unknown-linux-gnueabihf) or is the trace still coming from armv7-?
  • does Sailfish OS handle any and all GNU Linux binaries without a problem? (what's your glibc version)

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?

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 :)

Welcome to Rust!

This will download and install the official compiler for the Rust programming
language, and its package manager, Cargo.

It will add the cargo, rustc, rustup and other commands to Cargo's bin
directory, located at:

/root/.cargo/bin

This path will then be added to your PATH environment variable by modifying the
profile file located at:

/root/.profile

You can uninstall at any time with rustup self uninstall and these changes will
be reverted.

Rust is installed now. Great!

To get started you need Cargo's bin directory in your PATH environment variable.
Next time you log in this will be done automatically.

To configure your current shell run source $HOME/.cargo/env.
[root@Jolla tmp]# source $HOME/.cargo/env
PATH environment variable set.
You're ready to Rust!

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.

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.

MagaTailor commented Jun 5, 2016

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 :( @

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
make: *** [arm-unknown-linux-gnueabihf/stage0/lib/rustlib/arm-unknown-linux-gnueabihf/lib/stamp.core] Segmentation fault
```.
I was also cross-compiling with Linux kalix 4.3.0-kali1-amd64 #1 SMP Debian 4.3.5-1kali1 (2016-02-11) armv7l armv7l armv7l GNU/Linux with BUILD: Jolla-2.0.1.11-Sailfish_SDK_Target-armv7hl, 
but had also issue with "qemu: Unsupported syscall: 374".

I had to install additional libraries for cargo to run.

  • librtmp.so.1

Now, everything is working!

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

@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.

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.

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

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

@petevine It was my mistake,sorry. I was manually copying LLVM structure to /usr/local/include and I have mistakenly copy include into /usr/local/include/include.

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.

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++.

@corvinux Thanks, great job! That was the purpose of this whole exercise, i.e. to prove rustc bootstrapped on your own machine could actually run. And it seems you managed to produce a stage1 rustc and it crashes right away! If you run with VERBOSE=1 make you could find out the stage1 libcore build command and get a gdb trace.

On my own machine the command looks like this (I've inserted gdb --args in between):

CFG_LLVM_LINKAGE_FILE=/tmp/rust-master/arm-unknown-linux-gnueabihf/rt/llvmdeps.rs LD_LIBRARY_PATH=/tmp/rust-master/arm-unknown-linux-gnueabihf/stage1/lib:/tmp/rust-master/arm-unknown-linux-gnueabihf/llvm/Release/lib:$LD_LIBRARY_PATH gdb --args  arm-unknown-linux-gnueabihf/stage1/bin/rustc --cfg stage1 -C codegen-units=1 -Z orbit -C target-feature=+neon,+vfp4,-slowfpvmlx -C link-args="-s" -O --cfg rtopt -C rpath -C prefer-dynamic --target=arm-unknown-linux-gnueabihf -C target-feature=+v7,+vfp3  -L "arm-unknown-linux-gnueabihf/rt" -L native="/tmp/rust-master/arm-unknown-linux-gnueabihf/llvm/Release/lib"     --out-dir arm-unknown-linux-gnueabihf/stage1/lib/rustlib/arm-unknown-linux-gnueabihf/lib -C extra-filename=-fe3cdf61 -C metadata=fe3cdf61 src/libcore/lib.rs

Please explain how you solved the librustc_llvm link problem? (did you use libstdc++ or libc++?) I'm beginning to suspect the problem's coming from C++ issues.

@petevine, regarding solving thelibrustc_llvm link problem, it was --disable-libcpp which did the trick.

@MagaTailor

@corvinux If your own bootstrapped stage1 rustc still crashes I suggest opening a separate issue providing a gdb backtrace like I'd suggested above. (copy/paste the libcore build command and insert gdb --args right before arm-unknown-linux-gnueabihf/stage1/bin/rustc part, etc.)
For better readability, put the debug info between 2 pairs of four backticks "````"

Does the official distribution still segfault?

@corvinux In case you still need it, there's a work-around for this bug. See the linked thread above.

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.
This maybe not a rust problem though..
