Yocto 2.4.2无法执行_rootfs,因为存在依赖包

我正在使用Yocto2.4.2(rocko)、Ubuntu14.04LTS、Linux内核LTSI4.4和ARMCortexa15。在建立韦斯顿的核心形象时,存在许多问题。其中之一是:

ERROR: core-image-weston-1.0-r0 do_rootfs: Unable to install packages.

Collected errors:

 * Solver encountered 2 problem(s):

 * Problem 1/2:

    - nothing provides libgbm >= 1.0 needed by weston-2.0.0-r0.cortexa15hf-neon



 * Solution 1:

    - do not ask to install a package providing weston



 * Problem 2/2:

    - nothing provides libgbm >= 1.0 needed by weston-2.0.0-r0.cortexa15hf-neon



 * Solution 1:

    - do not ask to install a package providing weston-init

weston和weston init软件包需要libgbm>=1.0. 在我们当前的系统中,libgbm.bb已经存在。而且,我可以成功地构建libgbm。
