列出构建 Yocto 镜像所需的所有包/文件的 SRC_URI [英] Listing SRC_URI of all packages/files needed to build Yocto image

问题描述

我想列出我烘焙图像时 bitbake 将获取的所有文件.

I would like to list all files that bitbake will fetch when I bake an image.

目前，我可以通过执行 bitbake core-image-minimal -c fetchall 获取烘焙 Yocto 图像所需的所有文件的 SRC_URI，然后解析日志文件.

Currently, I am able to get the SRC_URI of all files needed to bake a Yocto image by executing bitbake core-image-minimal -c fetchall and then parse log files.

有没有更简单的方法来获得相同的结果而不需要下载文件?

Is there is a simpler way to get the same result without the need to download files ?

我不确定 bitbake 是否支持这样的功能.理想情况下，我正在寻找一个命令，该命令可以打印出包名称并列出具有相应 URL 的所有文件

I am not sure bitbake supports such feature. Ideally, I am looking for a command that prints out the package name and lists all files with corresponding URL

> bitbake core-image-minimal -c fetchall --print-only

推荐答案

通常 bitbake 不提供这样的功能.

Generally bitbake doesn't provides such functionality.

但是我能够创建一个简单的解决方案，创建简单的 .bbclass 文件，该文件在所有配方中都继承，将其添加到 local.conf 文件中，请参阅我的步骤是为了存档:

But I was able to create a simple solution witch creating simple .bbclass file which is inherited in all recipes, by adding it into local.conf file, please see my steps in order to archive that:

步骤:

1. 让我们创建一个 print-src.bbclass 类文件，用于获取和打印 SRC_URI 变量(记住将此类文件存储在可用的层中)conf/bblayers.conf):

1. let's create a class print-src.bbclass file used to get and print SRC_URI variable (remember to store this class file in layer which is available in conf/bblayers.conf):

$ cat print-src.bbclass

python do_print_src () {
    # should probably be indented
    srcuri = d.getVar('SRC_URI', True).split()
    bb.warn("SRC_URI look like: %s" % srcuri)
}

addtask do_print_src before do_fetch

将 INHERIT += "print-src" 添加到您的 conf/local.conf 文件

使用 bitbake --runonly 选项很重要，该选项允许为指定目标运行 taskgraph 的特定任务(使用 --runonly 选项 do_print_src 需要用作 print_src),

it is important to use bitbake --runonly option, that allows to run specific task of the taskgraph for the specified target (with --runonly option do_print_src needs to be used as print_src),

请注意，--runall=RUNALL 和 --runonly=RUNONLY 是通过 Yocto Sumo 2.5 版，>

Please note that --runall=RUNALL and --runonly=RUNONLY was introduced with Yocto Sumo release 2.5,

$ bitbake core-image-minimal --runonly print_src
