Question

我的Dockerfile：

heat

然后我创建图像：

FROM ubuntu:latest
MAINTAINER Dawid Stec <dawid.stec@gmail.com>
LABEL Description="Docker image for building arm-embedded"

RUN apt-get update && apt-get install -y \
  git \
  cmake \
  make \
  automake \
  libffi-dev \
  libssl-dev \
  libusb-1.0.0 \
  libusb-1.0.0-dev \
  software-properties-common \
  ccache

COPY toolchain /home/tools

ENV PATH="/home/tools/bin:${PATH}"

并登录图片：

sudo docker build -t lpc-arm .

在运行中的容器中，我看到了复制的文件。

docker run -i -t lpc-arm /bin/bash

但是当我尝试执行 arm-none-eabi-gcc 时，我收到了错误消息：

root@58f75da4406c:/home/tools/bin# ls

我应该能够执行该程序，但是为什么不能呢？

主机中的命令： ls -lrs工具链/

root@58f75da4406c:/home/tools/bin# ./arm-none-eabi-gcc
bash: ./arm-none-eabi-gcc: No such file or directory

和图片中

Answer 1

我猜想arm-none-eabi-gcc是为arm体系结构构建的二进制文件，而您试图在x86-64容器中执行它。

尝试将基本映像更改为https://hub.docker.com/r/arm32v7/ubuntu/或具有所需体系结构的其他映像。在这里，您可以找到这些图像的链接：https://github.com/docker-library/official-images#architectures-other-than-amd64

Answer 2

您正在尝试在64位体系结构上运行32位可执行文件：

root@8ccee441d384:/home/tools/bin# file arm-none-eabi-gcc
arm-none-eabi-gcc: ELF 32-bit LSB executable, Intel 80386, version 1 
(SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for 
GNU/Linux 2.6.8, stripped

您需要添加i386架构，以及libc6:i386，libncurses5:i386，libstdc++6:i386库软件包：

dpkg --add-architecture i386
apt-get update
apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386

安装这些软件包后，我设法运行了二进制文件：

root@8ccee441d384:/home/tools/bin# ./arm-none-eabi-gcc
arm-none-eabi-gcc: fatal error: no input files
compilation terminated.
