我有一个用于 Gumstix 板的基于 Yocto 的 Linux 映像。该图像包括 Bluez5 蓝牙堆栈。
本地配置文件：
... DISTRO_FEATURES_append = " bluetooth bluez5" ...
这成功构建了一个图像，我可以在其中使用 CLI 中的蓝牙模块。我想在 Python 中使用蓝牙模块，所以我添加了 pybluez 支持 -
myimage.bb：
... PYTHON_INSTALL_append = "python-pybluez \" ...
python_pybluez.bb：
DESCRIPTION = "Python bindings for the Linux Bluetooth stack"
SECTION = "devel/python"
DEPENDS = "bluez5"
LICENSE = "GPL"
SRC_URI = "https://github.com/karulis/pybluez/archive/master.zip"
SRC_URI[md5sum] = "37733f35ad5a0522b86fe39467481fd1"
SRC_URI[sha256sum] = "8e7e5e4e343da7e0ec2cd37b6dc12ee77da8e4c0863dd8a2d03ab06f9b657238"
S = "${WORKDIR}/PyBluez-${PV}"

当 bitbaked 和构建失败时，这会导致大量冲突：
NOTE: Preparing RunQueue
ERROR: Multiple .bb files are due to be built which each provide bluez-hcidump (/home/parallels/yocto/poky/meta/recipes-connectivity/bluez5/bluez5_5.28.bb /home/parallels/yocto/poky/meta/recipes-connectivity/bluez/bluez-hcidump_2.5.bb).
This usually means one provides something the other doesn't and should.
NOTE: Executing SetScene Tasks
ERROR: The recipe bluez5 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: 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.

看起来 pybluez 依赖于一大堆 Bluez4 配方和库，它们与 Bluez5 对应物发生冲突。通过强制 pybluez 使用 Bluez5 版本来解决这个问题是否正确？
