I'm new to v4l2 and
I want to use a saa7134 based tv-card and I patched kernel 2.4.19-rc3 with
v4l2-01-v4l2-api-2.5.8-pre2.diff.
The kernel compiled with no problems.
Then I compiled module saa7134 and put it in the corresponding directory for
my new kernel.
When I now do a
# modprobe saa7134
I get following error message:
# modprobe saa7134
/lib/modules/2.4.19-rc3/kernel/drivers/media/video/v4l1-compat.o: unresolved \

saa7134 failed
what do I have to do to get this working? (change kernel to 2.4.19-pre2?)
Did the patches partly fail when you applied them
(look for a file kernel/ksyms.c.rej)? They did with me, and
I had to go in and edit kernel/ksyms.c by hand, inserting
the do_select line below. (I assume you mean you used
v4l2-01-add-api-2.4.19-pre8.diff.gz and not the 2.5 patch
you mention)
EXPORT_SYMBOL(dcache_dir_close);
EXPORT_SYMBOL(dcache_dir_lseek);
EXPORT_SYMBOL(dcache_dir_fsync);
EXPORT_SYMBOL(dcache_readdir);
EXPORT_SYMBOL(do_select);
EXPORT_SYMBOL(dcache_dir_ops);
Also, I found that "make install" with the
saa7134 stuff kept wiping out my i2c modules,
so I re-installed the kernel modules with
make modules_install and then used an
older version of the saa7134 Makefile
to install it.
