depmod: *** Unresolved symbols in
/lib/modules/2.4.26/kernel/sound/isa/wavefront/snd-wavefront.o
depmod:         errno

The open/close/read system calls are implemented as inline functions
which change errno which isn't exported from the kernel.

We could reintroduce the dummy definition of errno for older kernels,
or use filp_* calls (like sound_firmware.c).


Regards,
Clemens

i guess sys_* functions are also not defined correctly on older
kernels.  they were open(), close(), read() with __KERNEL_SYSCALLS__.

how about to make a patch for old kernels to add the following?
(about line 1920 of wavefront_synth.c:)

#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,5)
#define __KERNEL_SYSCALLS__
#include <linux/unistd.h>
static int errno;
#define sys_open open
#define sys_close close
#define sys_read read
#else
#include <linux/unistd.h>
#endif

I don't have access to my Linux machine here, but I guess it does.

These definitions are already in alsa-driver/include/syscalls_26.h.


I'm going to test and apply this until tomorrow, but feel free to
apply it now if you want to release rc2 earlier. :)
