Bitbake:根据编译的图像修改bbappend [英] Bitbake: modify a bbappend depending on the image compiled

问题描述

我有两个不同的图像，它们使用了很多常见的程序包.其中之一是wpa-supplicant，它提供了默认配方安装的文件wpa_supplicant.conf.但是，我希望安装自己的wpa_supplicant.conf.

I have two different images which use a lot of common packages. One of them is the wpa-supplicant, which provides a file wpa_supplicant.conf installed by the default recipe. However, I want my own wpa_supplicant.conf to be installed.

我通过在图层中添加.bbappend来解决此问题.但是现在，我只希望在编译其中一个图像而不是另一个图像时应用此追加.

I have this solved by having a .bbappend in my layer. But now I only want this append to be applied when I compile one of the images, but not the other.

简而言之:是否有一种方法可以根据编译的图像启用/禁用.bbappend?

In short: is there a way to enable/disable a .bbappend depending on the image compiled?

注释:

• 我已经看到了此答案，这很相似，但是创建一个安装我的文件的新软件包却没有工作:许多软件包将尝试安装相同的文件，并且Bitbake返回错误.

• I have seen this answer which is similar, but creating a new package that install my file does not work: many packages will try to install the same file and Bitbake returns error.

• 这里的错误是我无法从两个不同的软件包安装相同的文件，这就是为什么这不是谢谢！

  推荐答案

  好吧，正如您链接到的答案中所指出的那样，您的图像不能影响任何其他配方.原因是每个配方都是独立于要构建的图像而构建的.

  Well, just as is stated in the answer that you link to, you can't have the image influence any other recipe. The reason is that each recipe is built indepent of which image you're building.

  是否打算将不同的映像安装到同一MACHINE上?否则，每个MACHINE可能会有不同的wpa_supplicant.conf.

  Are the different images intended to be installed onto the same MACHINE? Otherwise you could have different wpa_supplicant.conf for each MACHINE.

  对于同一MACHINE:

  • 使用ROOTFS_POSTPROCESS_COMMAND是解决此问题的一种方式
  • 添加两个wpa_supplicant.conf文件(名称不同)并将pkg_post_inst_${PN}(){xxx}脚本添加到wpa-supplicant中，该脚本在rootfs创建期间检测正在构建的映像，并选择正确的wpa_supplicant.conf./li>
  • 另一种解决方案是从bbappend中的wpa-supplicant包中删除wpa_supplicant.conf.创建两个新的软件包wpa-supplicant-conf1和wpa-supplicant-conf2，其中仅包括各自的wpa_supplicant.conf.理想情况下，这两个应该有一个
  • Using ROOTFS_POSTPROCESS_COMMAND is one way to solve this
  • Add both wpa_supplicant.conf-files (with differing names) andadd a pkg_post_inst_${PN}(){xxx} script to your wpa-supplicant, that during rootfs-creation time, detects which image is being built, and selects the corretct wpa_supplicant.conf.
  • Another solution is remove wpa_supplicant.conf from the wpa-supplicant package in your bbappend. Create two new packages wpa-supplicant-conf1 and wpa-supplicant-conf2, which just includes the respective wpa_supplicant.conf. Those two should ideally have a

  wpa-supplicant-conf1:

  RCONFLICTS_${PN} = "wpa-supplicant-conf2" 
  

  和wpa-supplicant-conf2

  RCONFLICTS_${PN} = "wpa-supplicant-conf1"
  

  在他们的食谱中.
