Yocto poky 在 function do_rootfs 上構建失敗

Question

我一直在按照https://www.linux4sam.org/bin/view/Linux4SAM/PokyBuild上的步驟使用 Yocto 為 SAMA5D27 評估套件構建 core-image-minimal 和 microchip-headless-image。 我被困在 bitbake core-image-minimal 和 microchip-headless-image 的 do_rootfs 命令上。

我已按照上述指南中的所有步驟操作，並添加了更多步驟以使這些步驟有效：

我將 Docker 與以下 Dockerfile 一起使用：

FROM ubuntu:18.04

RUN apt-get update 

RUN apt-get install sudo 

RUN sudo apt-get install -y git  

RUN sudo apt-get install -y python

RUN sudo apt-get install -y python3 

RUN sudo apt-get install -y vim

RUN sudo apt-get install -y binutils chrpath cpio cpp diffstat g++ gawk gcc make texinfo elfutils libc6-dev  wget 


# adding a user     
RUN useradd -ms /bin/bash user1
RUN usermod -aG sudo user1

RUN echo user1:user1 | chpasswd
CMD /bin/bash

進入 Docker 容器后，我使用以下命令運行構建腳本來執行指南中的步驟：

mkdir my_dir && cd my_dir

git clone git://git.yoctoproject.org/poky -b warrior 

git clone git://git.openembedded.org/meta-openembedded -b warrior

git clone git://code.qt.io/yocto/meta-qt5.git

git clone git://github.com/linux4sam/meta-atmel.git -b warrior

cd poky

source oe-init-build-env build-microchip

# change the local.conf and bblayers.conf based on suggestions in the guide 
cp -f /local.conf /my_dir/poky/build-microchip/conf/local.conf

cp -f /bblayers.conf /my_dir/poky/build-microchip/conf/bblayers.conf

# switch to the new user 
su user1

export PATH=$PATH:/my_dir/poky/bitbake/bin
sudo apt-get install locales
sudo dpkg-reconfigure locales
sudo locale-gen en_US.UTF-8

sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
export LANG=en_US.UTF-8

# give user1 permissions to modify all subdirectories within my_dir
sudo chmod -R a+rwx /my_dir

這是我收到的錯誤消息 - 沒有提到明確的錯誤，只是“退出代碼 1”：

and I've attached the log file for the failure with this message:

https://filebin.net/e02r8w5m3bn607qd

Any ideas what could be going wrong?

Edit: on further investigation, I realized that in /my_dir/poky/scripts/postinst-intercepts/update_gio_module_cache , ${binprefix} was coming out as empty, so that ${binprefix}qemuwrapper was nothing, and when you run qemuwrapper, which is the command run in update_gio_module_cache, you get the error message 'qemu-arm not found'. So I installed qemu-arm for ubuntu.

Further, I realized that the script gio-querymodules for sama5d27-som-ek1 is found at /my_dir/poky/build-microchip/tmp/work/sama5d27_som1_ek_sd-poky-linux-gnueabi/core-image-minimal/1.0-r0/recipe-sysroot-native/usr/libexec/gio-querymodules, not at $D${libexec}gio-querymodules, which expands in my system to, /my_dir/poky/build-microchip/tmp/work/sama5d27_som1_ek_sd-poky-linux-gnueabi/core-image-minimal/1.0-r0/rootfs/usr/libexec/gio-querymodules.

Once I fix these paths up and run bitbake -c rootfs core-image-minimal, I get the following error:

/my_dir/poky/build-microchip/tmp/work/sama5d27_som1_ek_sd-poky-linux-gnueabi/core-image-minimal/1.0-r0/recipe-sysroot-native/usr/libexec/gio-querymodules: Invalid ELF image for this architecture

Answer 1

在我的情況下，這個問題的解決方案有兩個：

1. 我更改了設置用戶權限的方式以及將用戶更改為：

   chmod -R g+rw /home/sama5d27

   chmod -R o+rw /home/sama5d27

   useradd -p user1 -s /bin/bash user1

2. 然后我得到了一個“os塊大小錯誤”，使用以下方法解決： https://github.com/openembedded/openembedded-core/blob/master/scripts/lib/wic/filemap.py
