Hi Mark, I have read your mail about minimal image posted on Feb 19 on this mail list. We try to reduce image size by what your said: 1. eglic configurability 2. using mklibs Right now after migrate eglic configurability to my local yocto branch, and I only enable 4 options ("locale-code nsswitch rtld-debug posix-clang-wchar ", pls. check in attachment) of eglibc just to make compile pass. When after create minimal image, the rootfs (tar.bz2) is still about 3.4M, same size as without adding configurability to eglibc. Could you give me some directions what should we do in next step? We also hope some information about how to use mklibs to reduce packages and image size? Thanks and Regards, Kai
