Do you have linux-libc-dev:amd64 installed? If not, please do.
Is this necessary if I'm using the i386 host architecture in Debian? I think I posted the following earlier:
dpkg -S /usr/include/asm-generic/unistd.h linux-libc-dev:i386, linux-libc-dev:mipsel: /usr/include/asm-generic/unistd.h
So, I have two architecture variants of the package installed already.
Although architecture-specific unistd.h files are provided by a surprising number of packages [*], I don't see any difference in behaviour between them with regard to this issue. For example:
diff /usr/mipsel-linux-gnu/include/asm-generic/unistd.h /usr/include/asm- generic/unistd.h 715a716,723
#define __NR_mlock2 284 __SYSCALL(__NR_mlock2, sys_mlock2) #define __NR_copy_file_range 285 __SYSCALL(__NR_copy_file_range, sys_copy_file_range) #define __NR_preadv2 286 __SC_COMP(__NR_preadv2, sys_preadv2, compat_sys_preadv2) #define __NR_pwritev2 287 __SC_COMP(__NR_pwritev2, sys_pwritev2, compat_sys_pwritev2)
718c726 < #define __NR_syscalls 284 ---
#define __NR_syscalls 288
They both exclude the required definitions without __ARCH_WANT_SYSCALL_NO_AT.
