<solved>Missing linux/uvcvideo.h Header

[daniel]

Hi packagers,

i missing on my system the linux/uvcvideo.h file.
If i read right it should available in kernel-devel package (3.2.18), but there isn't it.
Any ideas?

that's strange, why isn't find it by compile guvcview?

Code: [Select]

Did you check to be sure it actually was there, as it's supposed to be?

[root@fatman ~]# ls -l /usr/src/kernel-devel-3.2.18-pclos1.bfs/include/linux/ |grep uvc

[daniel]

it is there

Code: [Select]

[daniel@localhost guvcview-src-1.6.0]$ ls -l /usr/src/kernel-devel-3.2.18-pclos1.bfs/include/linux/ |grep uvc
-rw-r--r-- 1 root root   1569 Mai 22 21:17 uvcvideo.h

What's wrong?

What's wrong?

The error message only refers to linux/uvcvideo.h without the rest of the full path. Is it looking for it within the guvcview-src-1.6.0 directory? Check the makefile to see if part of the path structure is missing

seems version 1.6.0 had an bug. Version 1.5.3 build without any problems.

Next 1000 issues will be solved

Version 1.6.1 is out, perhaps the bug is fixed?

Sometime around kernel 3.2 the interface to uvcvideo changed from being IOCTL type interface to having a proper GLIBC interface.  As a result, for the 3.2 kernels there should be a uvcvideo.h for accessing the glibc API  (stuff in /usr/include/linux is for glibc and is provided by the glibc-headers-devel package).  The later versions of guvcview require this new interface.

I suspect you are using glibc-headers-devel-2.6.38.  This will not have linux/uvcvideo.h.
You need glibc-headers-devel-3.2.18 but that is currently only available in the Test section of the 64 bit repo.

Terry.

Edit:
BTW moving permanently to glibc-headers-devel-3.2.18 has important implications for the PCLinuxOS Admins to consider.
