docker - 使用Docker构建riot/helloworld

Question

这是我的设置:

docker pull riot/riotbuild

wget https://github.com/RIOT-OS/RIOT/archive/2019.04.zip

unzip 2019.04.zip

cd RIOT-2019.04/examples/hello-world/

make BUILD_IN_DOCKER=1 BOARD=stm32f4discovery all
所有这些都可以。

make BUILD_IN_DOCKER=1 BOARD=stm32f4discovery flash
此步骤失败。错误是:

Answer 1

我检查了脚本，实际上它最终将如下调用docker:

a)使BUILD_IN_DOCKER = 1 BOARD = stm32f4发现所有

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 flash

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'

它们几乎是相同的，并且容器的主要用途只是将源代码构建为stm32二进制文件，因为在启动容器时不会添加任何控制硬件的权限。

与 a)相比， b)也具有下一个输出:

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

实际上这与容器无关，它在主机上运行，​​根本原因是您没有在用于将stm32二进制文件刷新到设备的主机上安装 openocd。

看到 this，搜索 OpenOCD，很明显需要您安装openocd，然后在docker容器完成构建之后，二进制文件也将在主机中，就像它在docker卷中一样，最后主机上的 openocd可能会刷新您的二进制文件。
