Hello,
I get the following error when I try to build the V4L2 on Kernel
3.0.36+ for ARM architecture:
/root/v4l2/media_build/v4l/altera.c:2417:5: error: redefinition of 'altera_init'
int altera_init(struct altera_config *config, const struct firmware *fw)
^
In file included from /root/v4l2/media_build/v4l/altera.c:32:0:
/root/v4l2/media_build/v4l/../linux/include/misc/altera.h:41:19: note:
previous definition of 'altera_init' was here
static inline int altera_init(struct altera_config *config,
^
I checked the altera.h code and apparently, the IS_ENABLED macro is
not defined and causes this problem. I have prepared kernel source at
/lib/modules/3.0.36+/build/ and it builds successfully.
Can anyone help me on this issue?
Bests,
Isaac

What kernel tree are you using? There is no IS_ENABLED in 3.0, so apparently
you have a patched kernel. Do you actually need that altera driver? If not,
then why not disable it in the kernel config?

Hans

Hi Hans,
I am using Kernel 3.0.36+ download from this repository:
https://github.com/linux-rockchip/kernel_rockchip
It's a fork of https://github.com/rkchrome/kernel
I guess I don't need that driver. After disabling it through
menuconfig, I get this error:

^
And apparently yes, there is some issue with IS_ENABLED. Doesn't V4L2
apply patches to be compatible with older kernels (e.g. 3.0)?
To bypass this error, I manually added these two includes to
v4l2-.fh.h file (I guess this is not a good approach):
#include <linux/module.h>
#include <linux/export.h>
Now when I run make, I get different errors. Here is the output
truncated to 100 lines (there are many errors):

No. Whoever maintains that repository applied v4l code from some newer
kernel without apparently ever testing it. This is really the responsibility
of maintainer of that repository and is out of our control.
You need to address your questions to that repository maintainer, we can't
help, I'm afraid.

Ah I see. I have some issues with v4l2 on this kernel version and I am
trying to upgrade v4l2 to fix that.
One last question: Can I remove current v4l codes in kernel, replace
them with the V4L2 backport (provided by linuxtv), fix the
compatibility issues (hopefully) to get a kernel source with newer
v4l2 code?
I am not sure if the v4l2 backport is the same type of code that is
present in kernel source at "drivers/media/video",
"drivers/media/dvb", etc.
Thanks,
Isaac

Yes, you can, but it isn't easy.
In this repo:
http://git.linuxtv.org/cgit.cgi/hverkuil/cisco_build.git/tree/?h=cobalt-mainline
there is a patch-kernel.sh script that can patch a vendor kernel with the v4l
code from a fairly recent stable kernel (I think it is good for 3.14, I don't
know if it can backport from a 3.15 kernel).
You need to set the target, orig_source and source paths correctly and then
run it.
You end up with a huge patch that you can apply to your kernel.
It's probably still not enough since you may have to add compat code from
v4l/compat.h to the drivers you want to compile in. It depends on what
drivers you want to compile how much work that is.
I'm not going to give support for this, so you're on your own. The repo
owner really should fix his tree.
Regards,
Hans

Hi Hans,
I understand. I will get in touch with the maintainer to see how we
can fix this issue.
Thank you so much for the help,
