/home/yousong/git-repo/lede-project/opkg-lede/libopkg/file_util.c: In
function ‘file_md5sum_alloc’:
/home/yousong/git-repo/lede-project/opkg-lede/libopkg/file_util.c:144:2:
warning: passing argument 1 of ‘md5sum’ discards ‘const’ qualifier from pointer
target type [enabled by default]
In file included from
/home/yousong/git-repo/lede-project/opkg-lede/libopkg/file_util.c:28:0:
/home/yousong/.usr/include/libubox/md5.h:56:5: note: expected ‘char *’ but
