Yocto - 如何将 blkid.h 文件添加到 rootfs

Question

I would like to add to some Yocto Linux distribution my own application that includes blkid.h file. In the.manifest file I found libblkid1 library and util-linux-blkid package but in the rootfs I have no such a file. Which package or library I should add to the image to get blkid.h file?

Thank you in advance for any help.

Answer 1

liblkid1 is a package from util-linux recipe ( util-linux-libblkid ). If you want to have the headers, you probably need to add the development package of util-linux-libblkid :

IMAGE_INSTALL += "util-linux-libblkid-dev"

But I don't understand why you need the headers, are you compiling on the target? Because if you use Yocto to compile your application, the header will be on the host side during the image generation, and will not be necessary on the target. Or if you compile with the SDK, you also don't need the headers on the target.
