Default link_elf error while loading gspca.ko

I wanted to see if a usb-cam could work in my freebsd 7, so I tried some listed modules. pwc.ko loaded but the cam did not work. So I tried gspca.ko from http://info.iet.unipi.it/~luigi/Free...x_bsd_kld.html but I the module did not load because of the error
Code:
link_elf: symbol msleep undefined
I see that this msleep problem is mentioned elsewhere but no solutions.
Any suggestions about what to do?

Default msleep on Linux vs. FreeBSD

I've often wondered about the differences between the Linux msleep and FreeBSD msleep -- I've actually lost some sleep thinking about it. They appear to be the same in name only. Am I confused here? If so, jump in and correct me.

The Linux msleep simply goes into a while spin-loop counting down a timeout on schedule_timeout_uninterruptible( ). It seems to be a closer match to the Standard C library call: usleep.

The FreeBSD msleep seems to be a different beast entirely. A better name would be 'mutex_sleep' since that is what it does. In fact, we shouldn't use FreeBSD msleep since it has been depreciated, use mtx_sleep instead.

For linux_kmod_compat would a better match to the Linux msleep be the FreeBSD kernel function pause?:
void pause(const char *wmesg, int timo);
or is there something better for use in the kernel, drivers, and KLDs?

If you are using the kernel module from that site, I think it is very out of date. (the rest of the site is, at any rate)

Linux-gspca-kmod is in the ports at /usr/ports/multimedia/linux-gspca-kmod. Other options are linux-ov511-kmod and pwcbsd, also in multimedia/.
Possibly, msleep, having been depreciated, has now been removed. If you build from ports, it won't use it. (I am using gspca on my 7.S system right now.)

It's a problem with the Makefile/sources...
It never reads you are in FreeBSD 7.0... Now I am at a WinXP station with no access to the code, but I'll send you an update once I get home.

If you can't wait, go over the source files and comment out any IF $OSVERSION referring to FreeBSD 7 or greater and the corresponding END, especially the one referring to msleep. You can also delete the IF loops for FreeBSD6.x

Hope this helps. I have been able to make my Logitech Webcam work with this hack... However, kopete will not recognize it, but you can play around streaming with VLC
