docker - 使用 Docker 构建 riot/helloworld

Question

这是我的设置：

1. docker pull riot/riotbuild
2. wget https://github.com/RIOT-OS/RIOT/archive/2019.04.zip
3. unzip 2019.04.zip
4. cd RIOT-2019.04/examples/hello-world/

5. make BUILD_IN_DOCKER=1 BOARD=stm32f4discovery all

   这一切都没问题。

6. make BUILD_IN_DOCKER=1 BOARD=stm32f4discovery flash

   这一步失败了。错误是：

Answer 1

我检查了脚本，实际上它最终会调用 docker 作为下一个：

a) 使 BUILD_IN_DOCKER=1 BOARD=stm32f4discovery 全部

docker run --rm -t -u "$(id -u)" \
-v '/usr/share/zoneinfo/PRC:/etc/localtime:ro' -v '/home/shubuntu1/g/RIOT-2019.04:/data/riotbuild/riotbase' -e 'RIOTBASE=/data/riotbuild/riotbase' -e 'CCACHE_BASEDIR=/data/riotbuild/riotbase' -e 'BUILD_DIR=/data/riotbuild/riotbase/build' -e 'RIOTPROJECT=/data/riotbuild/riotbase/examples/hello-world' -e 'RIOTCPU=/data/riotbuild/riotbase/cpu' -e 'RIOTBOARD=/data/riotbuild/riotbase/boards' -e 'RIOTMAKE=/data/riotbuild/riotbase/makefiles'     \
-e 'BOARD=stm32f4discovery' \
-w '/data/riotbuild/riotbase/examples/hello-world/' \
'riot/riotbuild:latest' make all 'BOARD=stm32f4discovery'

b) 使 BUILD_IN_DOCKER=1 BOARD=stm32f4discovery 闪存

docker run --rm -t -u "$(id -u)" \
-v '/usr/share/zoneinfo/PRC:/etc/localtime:ro' -v '/home/shubuntu1/g/RIOT-2019.04:/data/riotbuild/riotbase' -e 'RIOTBASE=/data/riotbuild/riotbase' -e 'CCACHE_BASEDIR=/data/riotbuild/riotbase' -e 'BUILD_DIR=/data/riotbuild/riotbase/build' -e 'RIOTPROJECT=/data/riotbuild/riotbase/examples/hello-world' -e 'RIOTCPU=/data/riotbuild/riotbase/cpu' -e 'RIOTBOARD=/data/riotbuild/riotbase/boards' -e 'RIOTMAKE=/data/riotbuild/riotbase/makefiles'     \
-e 'BOARD=stm32f4discovery' \
-w '/data/riotbuild/riotbase/examples/hello-world/' \
'riot/riotbuild:latest' make  'BOARD=stm32f4discovery'

它们几乎相同，容器的主要用途只是构建 stm32 二进制文件的源代码，因为它在启动容器时没有添加任何控制硬件的权限。

与 相比a)，b)还有下一个输出：

### Flashing Target ###
sh: 1: openocd: not found
/home/shubuntu1/g/RIOT-2019.04/examples/hello-world/../../
Makefile.include:538: recipe for target 'flash ' 制作失败
：*** [flash] 错误 127

这实际上与容器无关，它在主机上运行，​​根本原因是您没有安装openocd在用于将 stm32 二进制文件闪存到设备的主机上。

看到这个，搜索一下OpenOCD，很明显需要你安装openocd，然后在docker容器完成构建后，二进制也将在主机中，因为它在docker卷中，最后openocd在主机上可以刷你的二进制文件。
