Segmentation fault while executing crosscompiled binary @ RPi 1 Rev. b #5

Closed iamsebastian closed 8 years ago

iamsebastian commented 8 years ago

Hello.

If I compile something with: rustc -C linker=arm-linux-gnueabihf-gcc --target=arm-unknown-linux-gnueabihf hello.rs, copy that binary to my RPi1b and trying to execute that binary, after copying finished, I get a segmentation fault at the @RPi1b: [1] 20396 segmentation fault ./hello Any ideas why this is happening?

CPU on my RPi1b:

By the way: hello.rs does not contain more than the default cargo hello-world:

pub fn main() {
  println!("Hello world!");
}

Are you using the latest ARMv6-armhf binary builds as the library for your cross compiler?

I just got them building in the Raspbian container again last night and my test on the Raspberry Pi worked. https://github.com/warricksothr/RustBuild/issues/4

However I haven't tried crosscompiling with the latest builds, so I'll look into that.

Forgot that the cross compiler requires matching versions of Rustc. I may need to recompile the latest beta and stable. I'll let you know after my tests. Which were you using? Beta or Stable?

warricksothr commented 8 years ago

With the latest stable build for ARMv6-armhf I too am getting a segmentation fault when I cross compile.

Here is the trace of the fault that I'm looking into now.

The weirdest part is that the compiled binary works on my ARMv7 machine with no issue.

Additionally the same stable release of the ARMv6-armhf versions of cargo and rust compile and run a hello world on the Pi. So I don't think it's the build that's wrong. Something in the crosscompiling linking must be off.

It's your linker. I bet it's built for crosslinking ARMv7.

I just put together a container with Debian Wheezy and the Raspberry Pi's Rasbian GCC 4.8.3 crosslinker and those builds work on my Raspberry Pi B.

In my Debian Wheezy container with the Raspbian Cross Linker

root@add04ae671e8:~/dev/rust/hello_world# cat hello.rs
pub fn main() {
        println!("Hello World!");
}
root@add04ae671e8:~/dev/rust/hello_world# rustc -C linker=arm-linux-gnueabihf-gcc --target=arm-unknown-linux-gnueabihf hello.rs
root@add04ae671e8:~/dev/rust/hello_world# file hello
hello: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0x3e2dd5817ed574d3a57b80a51ae972d8bb22d9cb, not stripped
root@add04ae671e8:~/dev/rust/hello_world# scp hello pi@192.168.2.117:~

On My Raspberry Pi B

pi@raspberrypi ~ $ ./hello
Hello World!

Also the file sizes for the natively compiled vs the cross compiles are much closer now.


pi@raspberrypi ~ $ ls -al
...
-rwxr-xr-x 1 pi   pi   435390 Oct  9 00:32 hello # <- The Cross Compiled Binary
-rwxr-xr-x 1 pi   pi   435724 Oct  8 21:20 main # <- The Natively Compiled Binary
...

I've done the work of creating a docker image that contains everything necessary to build rust stable 1.3.0 cross compiled binaries for ARMv6 devices with atleast glibc 2.13+

It's on docker hub as sothr/rustbuild:armv6-crosscompile

https://hub.docker.com/r/sothr/rustbuild/
