Question

我有一个不知名的库，并且该库没有可用的软件包https://github.com/dailab/libsml通常，我通过执行make install在设备上安装该库
如何在我的Linux发行版中将此库作为软件包添加。就像我可以在我的python

中添加local.conf或其他任何食谱一样

我的local.conf看起来像这样

MACHINE ?= "phyboard-regor-am335x-1"

DISTRO ?= "yogurt"

# The following line disables the autostart of the phytec-qtdemo by
# default, but you can start the demo anytime using

# filesystem:
#IMAGE_ROOTFS_EXTRA_SPACE = "524288"

如果您不是yocto版本的2.4+版本，则可以使用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

这几乎是您所需要的，但是有时您必须对其进行一些调整以确保交叉编译。

在这种情况下，它将构建并运行测试，显然，在交叉构建时，我们可以构建测试，但是我们可以在构建计算机上运行它们，因此您必须禁用它。您可以在配方中或通过补丁来这样做。例如通过配方，您可以将do_configure函数更改为类似的内容

do_configure () {
    # Specify any needed configure commands here
    sed -i -e "s#@./test##g" ${S}/test/Makefile
}

也可以更改do_install，以便它可以在目标上安装所需的文件

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
}

构建并查看是否一切正常

devtool build libsml

如果所有版本都可以构建，则可以将配方应用于您选择的层（例如meta-oe）

devtool finish libsml meta-oe -f

就这样，现在您应该在meta-oe层中看到该食谱，您可以尝试构建它

bitbake libsml
