Re: Patching kernel headers


Hi Arnaud,

my simulator executes MIPS instructions, so when I have system calls the values for flags like O_APPEND, O_CREATE, O_TRUNC in MIPS cross compiled binaries are not the same like on host.

if it runs in a simulator, why would you need both (host's and
target's) fcntl.h to be the same ?
