在Yocto Morty中咬住最新的Gstreamer

我想在Yocto Morty中点击最新的Gstreamer，但错误已经发生，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sources目录中，并将BBLAYERS + =“$ {BSPDIR} /sources/meta-gstreamer1.0”添加到build_fb / bblayers.conf中。 然后我咬了fsl-image-gui并发生了以下错误。

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

我发现错误“Exception：TypeError：getVar（）缺少1个必需的位置参数：'expand'”在Yocto 2.3（Pyro）https://bugzilla.yoctoproject.org/show_bug.cgi?id=3314处修复。 此外，YP核心称Yocto Morty的gstreamer版本为1.8.3（参见https://www.yoctoproject.org/downloads/core/morty22更新标签）。

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？如果我们想实现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。有人会帮我吗？

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.

1 个答案:

答案 0 :(得分：1)

由于您要将旧版Yocto的配方迁移到较新版本，因此您必须面对this change in Yocto： expand 参数（第二个）到 getVar（）的后果和 getVarFlag（）已成为必填项（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，并至少添加 False 作为第二个参数。
