openwrt编译error: ext4_allocate_best_fit_partial: failed to allocate 13 blocks, out of space?

编译openwrt时候报如下错误：

Creating filesystem with parameters:
    Size: 50331648
    Block size: 4096
    Blocks per group: 32768
    Inodes per group: 6000
    Inode size: 256
    Journal blocks: 0
    Label: 
    Blocks: 12288
    Block groups: 1
    Reserved blocks: 0
    Reserved block group size: 7
error: ext4_allocate_best_fit_partial: failed to allocate 13 blocks, out of space?
make[5]: *** [mkfs-ext4] Error 1

解决办法：

make menuconfig

找到菜单项"Target Images","Root filesystem partition size (in MB)"

把值改大即可

出现这种情况通常都是修改编译菜单，加了很多东西后，导致编译出来的镜像比较大，如果运行在raspberry，cubieboard一些开发板上，改大无所谓
