在 Yocto Morty 中 Bitbake 最新的 Gstreamer

Question

我想在 Yocto Morty 中 bitbake 最新的 Gstreamer，但出现错误，无法实现 Gstreamer。

我在https://github.com/dv1/meta-gstreamer1.0 找到了 gstreamer 1.12.2 配方。 所以我将 meta-gstreamer1.0 目录放在源目录中，并将 BBLAYERS += " ${BSPDIR}/sources/meta-gstreamer1.0 " 添加到 build_fb/bblayers.conf 中。 然后我 bitbaked fsl-image-gui 并出现以下错误。

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

我发现错误“异常：TypeError：getVar() 缺少 1 个必需的位置参数：'expand'”已在 Yocto 2.3(Pyro) 中的 https://bugzilla.yoctoproject.org/show_bug.cgi?id=3314 中修复。 此外，YP 核心表示 Yocto Morty 的 gstreamer 版本是 1.8.3（请参阅 https://www.yoctoproject.org/downloads/core/morty22 更新选项卡）。

这些事情是否意味着我们无法在 Yocto Morty 中实现 gstreamer 1.12.2 或更高版本？有什么办法吗？如果我们要实现 gstreamer 1.12，我们是否必须使用 Yocto Pyro 或更高版本？

PS：

我重写 getVar 和 bitbake 继续。但是我得到了以下错误。有人可以帮我吗？

ERROR: gstreamer1.0-plugins-base-1.12.2-r0 do_populate_sysroot: The recipe gstreamer1.0-plugins-base is trying to install files into a shared area when those files already exist. Those files and their manifest location are:

Please verify which recipe should provide the above files.
The build has stopped as continuing in this scenario WILL break things, if not now, possibly in the future (we've seen builds fail several months later). If the system knew how to recover from this automatically it would however there are several different scenarios which can result in this and we don't know which one this is. It may be you have switched providers of something like virtual/kernel (e.g. from linux-yocto to linux-yocto-dev), in that case you need to execute the clean task for both recipes and it will resolve this error. It may be you changed DISTRO_FEATURES from systemd to udev or vice versa. Cleaning those recipes should again resolve this error however switching DISTRO_FEATURES on an existing build directory is not supported, you should really clean out tmp and rebuild (reusing sstate should be safe). It could be the overlapping files detected are harmless in which case adding them to SSTATE_DUPWHITELIST may be the correct solution. It could also be your build is including two different conflicting versions of things (e.g. bluez 4 and bluez 5 and the correct solution for that would be to resolve the conflict. If in doubt, please ask on the mailing list, sharing the error and filelist above.
ERROR: gstreamer1.0-plugins-base-1.12.2-r0 do_populate_sysroot: If the above message is too much, the simpler version is you're advised to wipe out tmp and rebuild (reusing sstate is fine). That will likely fix things in most (but not all) cases.

Answer 1

由于您要将旧版本 Yocto 的配方迁移到新版本，您必须面临this change in Yocto 的后果：expand 参数（第二个）到 getVar() 和 getVarFlag() 已成为强制要求 (from bitbake user manual for morty)，之前默认为 False。因此，您应该更正所有这些操作的出现，并至少添加 False 作为第二个参数。
