linux-gspca-kmod: "symbol msleep undefined"

[Pierre-Evariste Dagand]

Hi all,

I am trying to get my webcam working with the linux-gpsca driver.

I have updated my ports to the latest version of linux-kmod-compat and
linux-gspca-kmod:

linux-kmod-compat-20080408
linux-gspca-kmod-1.0.20

They compile fine, with the following warning for linux-gspca-kmod:

> In file included from gspca_core.c:39:
> /usr/local/share/linux-kmod-compat/linux_compat/linux/module.h:218:1: warning: "msleep" redefined
> In file included from /usr/local/share/linux-kmod-compat/linux_compat/linux/module.h:45,
>                  from gspca_core.c:39:
> @/sys/systm.h:307:1: warning: this is the location of the previous definition

And:

> In file included from /usr/local/share/linux-kmod-compat/linux_compat/ldev_stub.h:48,
>                  from /usr/local/share/linux-kmod-compat/linux_compat/linux_compat.c:44:

> /usr/local/share/linux-kmod-compat/linux_compat/linux_compat.c:76: warning: nested extern declaration of 'msleep'

But when I try to load the module with:

> kldload gspca

I get:

> kldload: can't load gspca: No such file or directory

And, in dmesg:

> link_elf: symbol msleep undefined

The webcam works in Linux, it is:

> [spca5xx_probe:8263] Camera type S561
> [spca5xx_getcapability:2241] maxw 352 maxh 288 minw 160 minh 120

> --- video capability ---

> channels: 1

My FreeBSD version is 7.0-RELEASE on i386, with gcc 4.2.1.

Am I doing something wrong ?

And if it is not a chair-to-keyboard interface bug on my side, I would
be pleased to help hunting that bug.

Regards,
