如何在 Yocto 构建中将第三方库作为包添加
how to add a third party library as a package in Yocto build
我有一个不知名的库，并且没有可用于该库的包 https://github.com/dailab/libsml 通常我通过 make install
在我的设备上安装该库
我怎样才能将这个库作为一个包添加到我的 Linux 发行版中。就像我可以在 local.conf
中添加 python 或任何其他食谱一样
我的local.conf看起来像这样

如果你没有yocto release 2.4+版本可以使用devtool添加配方
devtool add libsml https://github.com/dailab/libsml
它将创建一个食谱模板
workspace/recipes/libsml/libsml_git.bb
这几乎就是您所需要的，但有时您必须稍微调整一下以确保交叉编译。
在这种情况下，它构建并 运行 测试，显然在交叉构建时我们可以构建测试，但我们可以 运行 它们在构建机器上，所以你必须禁用它。你可以在食谱中或通过补丁来做到这一点。例如通过食谱，您将 do_configure 函数更改为类似这样的东西
do_configure () {
# Specify any needed configure commands here
sed -i -e "s#@./test##g" ${S}/test/Makefile
}
也可能会更改 do_install 以便它可以在目标上安装您需要的文件
do_install () {
install -d ${D}${libdir} ${D}${includedir}
install -m 0644 ${B}/sml/lib/libsml.* ${D}${libdir}
rm -rf ${D}${libdir}/libsml.o
cp -R --no-dereference --preserve=mode,links ${S}/sml/include/* ${D}${includedir}
install -D -m 0644 sml.pc ${D}${libdir}/pkgconfig/sml.pc
}
搭建看看是否一切正常
devtool build libsml
如果所有构建都可以将配方应用到您选择的层（比如 meta-oe）
devtool finish libsml meta-oe -f
就是这样，现在你应该在meta-oe层看到配方，你可以尝试构建它
bitbake libsml
