找不到 yocto SDK krogoth cmake FindBoost

Question

我正在尝试在 krogoth 上使用扩展环境在 Yocto SDK 中找到增强库 (cmake)。

默认cmake查找_

find_package(Boost REQUIRED)

标准错误信息

Unable to find the requested Boost libraries. Unable to find the Boost header files. Please set BOOST_ROOT to the root directory containing Boost or BOOST_INCLUDEDIR to the directory containing Boost's headers. Call Stack (most recent call first): CMakeLists.txt:3 (find_package)

以下是我的 conf/local.conf

的片段

IMAGE_INSTALL_append = " boost-dev"
IMAGE_INSTALL_append = " boost"
IMAGE_INSTALL_append = " kernel-devsrc"

MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS += "kernel-module-hello"
KERNEL_MODULE_AUTO_lOAD += "hello-md"

LCHAIN_HOST_TASK_append = "${SDK_EXTRA_TOOLS}" 
SDK_EXTRA_TOOLS = " nativesdk-cmake

我用的是原生cmake auke@xenialxerus:~/workspace/beaglebone-dev/build$ which cmake /home/auke/workspace/beaglebone-dev/poky-sdk/tmp/sysroots/x86_64-linux/usr/bin/

因为我：

source environment-setup-cortexa8hf-neon-poky-linux-gnueabi

寻找通常的 headers 在：

find ./tmp/sysroots/beaglebone/usr/include/boost/
..
/tmp/sysroots/beaglebone/usr/include/boost/vmd/list/to_seq.hpp
./tmp/sysroots/beaglebone/usr/include/boost/vmd/list/to_tuple.hpp
./tmp/sysroots/beaglebone/usr/include/boost/vmd/to_list.hpp
./tmp/sysroots/beaglebone/usr/include/boost/vmd/empty.hpp
./tmp/sysroots/beaglebone/usr/include/boost/vmd/is_list.hpp
./tmp/sysroots/beaglebone/usr/include/boost/vmd/size.hpp
./tmp/sysroots/beaglebone/usr/include/boost/vmd/get_type.hpp
./tmp/sysroots/beaglebone/usr/include/boost/vmd/assert_is_identifier.hpp
./tmp/sysroots/beaglebone/usr/include/boost/vmd/is_number.hpp
..

就像二进制文件一样：

./tmp/sysroots/beaglebone/usr/lib/libboost_system-mt.a
./tmp/sysroots/beaglebone/usr/lib/libboost_iostreams.so.1.60.0
./tmp/sysroots/beaglebone/usr/lib/libboost_serialization-mt.a
./tmp/sysroots/beaglebone/usr/lib/libboost_date_time-mt.a
./tmp/sysroots/beaglebone/usr/lib/libboost_date_time.a
./tmp/sysroots/beaglebone/usr/lib/libboost_thread.so
./tmp/sysroots/beaglebone/usr/lib/libboost_signals-mt.a
./tmp/sysroots/beaglebone/usr/lib/libboost_date_time-mt.so
./tmp/sysroots/beaglebone/usr/lib/libboost_graph-mt.a
./tmp/sysroots/beaglebone/usr/lib/libboost_iostreams.so
./tmp/sysroots/beaglebone/usr/lib/libboost_regex.so
./tmp/sysroots/beaglebone/usr/lib/libboost_wserialization.so.1

有什么我可能忽略的地方吗？

你应该使用 bitbake -c populate_sdk <image_name>根据您的图片生成SDK；

As an alternative to locating and downloading a toolchain installer, you can build the toolchain installer one of two ways if you have a Build Directory:

*Use bitbake meta-toolchain. This method requires you to still install the target sysroot by installing and extracting it separately. For information on how to install the sysroot, see the "Extracting the Root Filesystem" section.

*Use bitbake -c populate_sdk. This method has significant advantages over the previous method because it results in a toolchain installer that contains the sysroot that matches your target root filesystem.

此外，使用变量 TOOLCHAIN_HOST_TASK 添加更多包。
http://www.yoctoproject.org/docs/1.8/ref-manual/ref-manual.html

This variable lists packages the OpenEmbedded build system uses when building an SDK, which contains a cross-development environment. The packages specified by this variable are part of the toolchain set that runs on the SDKMACHINE, and each package should usually have the prefix "nativesdk-". When building an SDK using bitbake -c populate_sdk , a default list of packages is set in this variable, but you can add additional packages to the list.

例如

TOOLCHAIN_HOST_TASK += “nativesdk-libqt5core-dev”
