Hi, I am wondering if anyone has successfully compiled latest kernel using clang, I have been having problem with it for the last few month, and here is the error that I have:
In file included from drivers/tty/tty_io.c:103: ./include/linux/termios_internal.h:37:5: error: conflicting types for 'user_termio_to_kernel_termios' int user_termio_to_kernel_termios(struct ktermios *, struct termio __user *); ^ ./include/asm-generic/termios.h:20:19: note: previous definition is here static inline int user_termio_to_kernel_termios(struct ktermios *termios,
Not enough is shown to be sure, but I think the problem is that a function is declared external not inline before being defined as static inline. My guess is that gcc accepts that without comment, even though it should not, and clang rejects it with a not-so-great error message.
