exec format error

Question

exec format error

360disrupt opened this issue 5 years ago · comments

Hi, I'm running the script on a raspberry pi 4& raspbian buster. I get an error: exec format error for the script.

FROM arm32v7/node
ENV NODE_VERSION 11.15.0
WORKDIR ./

# install dependencies
RUN apt-get update;\
    apt-get install qemu qemu-user-static binfmt-support -y;\
    apt-get install i2c-tools -y;

# nodejs packages
COPY package*.json ./
RUN npm install --only=production

# copy app
COPY  src/ ./

# add logs folder
RUN mkdir -p /logs/

# wait for MongoDB launch
ADD https://github.com/ufoscout/docker-compose-wait/releases/download/2.5.1/wait /wait
RUN chmod +x /wait

EXPOSE 8080

STOPSIGNAL SIGTERM

CMD /wait && npm run start

I found that adding a shebang on top of the script helps, e.g.
http://kimh.github.io/blog/en/docker/gotchas-in-writing-dockerfile-en/

But the wait is of type ELF 64-bit LSB executable, x86-64, version 1 (SYSV) so I guess that won't help at least:

I never worked with rust, so I'm not sure if adding one on top of the entry file works. I could add one (probably here: https://github.com/ufoscout/docker-compose-wait/blob/master/src/lib.rs) and make a PR?

Any help appreciated, thx!

Hi @360disrupt
the prebuilt executable is for an x64 architecture which is the docker default one. So, you cannot use it on a raspberry pi.
You should instead clone this repo and compile it from scratch for your target architecture. This could be as easy as executing these two commands (you need a rust compiler):

> rustup target add armv7-unknown-linux-gnueabihf
> cargo build --target=armv7-unknown-linux-gnueabihf

I'll come back in 3 weeks and test it! Thx

Hi @ufoscout thx for the help. I installed rust. Unfortunately, the build does not work:

hi @360disrupt

Could you provide version numbers of your rust compiler (rustc) and cargo:

$ rustc --version

And

$ cargo --version

Not sure if it is needed to locate the problem, but it might help.

Jonas Brømsø · Answer 5 · Fri Aug 30 2019 02:12:43 GMT+0800 (China Standard Time)

Hi @360disrupt

Could you try adding the following line to the top of the file src/lib.rs

#![ allow( bare_trait_objects ) ]

Tip lifted from this issue.

I can make the warnings go away, but I cannot compile anyway, since I seem to be missing the necessary C header files required for the compilation.

@360disrupt
If you build from a linux x64 machine and you have docker installed locally, you can use this simple procedure (based on cross ) that will take care of all needed low level dependencies for you:

cargo install cross
cross build --target=armv7-unknown-linux-musleabihf --release

I tried it right now and it worked like a charm.

I'll update the docs with this information asap.

@ufoscout I'm working from MAC OS but I have a Ubuntu VM on parallels. So far I installed

git, docker.io
cloned the repo again on my VM
installed cross with cargo
added /root/.cargo/bin to PATH
uninstalled rust
instaled rustup
