Please + use -static when linking with glibc to see the difference. + + +Q: Should I compile my kernel with the diet libc? +A: The kernel is not linked against any libc. In fact, the libc is the + user space interface to the kernel. So unless you are talking about + "user mode linux" (which is a special version of the kernel that + happens to be a user space program) you cannot link the kernel + against the diet libc. Linking user space Linux with the diet libc + should be possible in theory but I don't think anyone has actually + tried it. |
