增加打开ADB后，liblog缺少

snap

在打开ADB选项后，出现缺省 liblog 的错误，请问怎么解决？

umask 0022 && make -C /home/rk3308-linux-firefly-32bit/buildroot O=/home/lifong/rk3308-linux-firefly-32bit/buildroot/output/rockchip_rk3308_32_debug

Makefile:543: *** liblog is in the dependency chain of libcutils that has added it to its _DEPENDENCIES variable without selecting it or depending on it from Config.in.  Stop.

snap

选了liblog后，提示：

没有找到：../external/liblog

buildroot/package/rockchip/liblog/liblog.m

LIBLOG_SITE = $(TOPDIR)/../external/liblog
LIBLOG_SITE_METHOD = local
LIBLOG_INSTALL_STAGING = YES

$(eval $(cmake-package))
