Hi,

I had no problem to install this driver under RH-8.0 but with Gentoo it gives me trouble...

Ok first, I compiled my kernel with video4linux (not as module) and usb stuff. Then I downloaded "qce-ga-0.40c.tar.gz" file and compiled it.
When I type ./quickcam.sh I get theses lines:

[root@mymachine qce-ga-0.40c]# ./quickcam.sh
insmod: videodev: no module by that name found
insmod: usbcore: no module by that name found
insmod: usb-uhci: no module by that name found
insmod: usb-ohci: no module by that name found
insmod: uhci: no module by that name found
./quickcam.sh: /proc/sys/kernel/sysrq: No such file or directory
insmod: a module named mod_quickcam already exists
Module Size Used by Tainted: P
mod_quickcam 41264 0 (unused)
NVdriver 1067104 10 (autoclean)

snd-timer 11848 0 [snd-pcm]

snd 30028 0 [snd-pcm-oss snd-mixer-oss snd-ens1371 snd-raw
midi snd-seq-device snd-pcm snd-timer snd-ac97-codec]

What does it mean?

Thanks.

Hi,

I use the same module. The install script (quickcam.sh) is looking to install the usb modules, but they are compiled right into the kernel, so it can't find usb*, and videodev. I don't use the script. I compile the quickcam module, move mod_quickcam.o to /lib/modules/2.x.x/kernel/drivers/usb/. My /etc/modules/autoload has
Code:
bttv
mod_quickcam
uhci

That loads up everything I need. Funny, I just noticed now that uhci is after mod_quickcam, but it still works.

If you recompile your kernel, you will have to put mod_quickcam.o back into the modules directory.

Thanks for your quick answer! I wanted to try that but my /lib/modules/2.4.19/kernel/drivers/usb/ directory does not exist...Did I forget to compile something into my kernel?

Thanks.

Whoops, brain fart by me. If you compiled the usb right into the kernel, there won't be a usb directory. Actually, I believe you can put it anywhere the kernel will look for modules. So, stick it in with some other drivers in the tree.

Let us know how it goes.

I'm having a problem actually compiling the module. This is what I get:

Code:

bash-2.05b$ make
gcc -I/usr/src/linux/drivers/usb -I/usr/src/linux/include -include /usr/src/linux/include/linux/config.h  -O3 -Wall -Wstrict-prototypes -fomit-frame-pointer  -pipe -DMODULE -D__KERNEL__ -DEXPORT_SYMTAB -DMODVERSIONS -include /usr/src/linux/include/linux/modversions.h -c quickcam.c
In file included from quickcam.c:58:
quickcam.h:80: parse error before "urb_t"
quickcam.h:80: warning: no semicolon at end of struct or union
quickcam.h:190: field `sbuf' has incomplete type
quickcam.c:429: confused by earlier errors, bailing out
make: *** [quickcam.o] Error 1


I was able to compile it on redhat 7.3 a while back.
Anyone know how to how to fix this?

i've done some c programming in the past so I took a look at the quickcam.h file but i dont see any problems...
lines 76-87:
Code:

struct usb_device;

struct quickcam_sbuf {
   char *data;
   urb_t *urb;
};

struct palette_list {
     int num;
     char *name;
     int supported;
};

I'm not sure about this, because I have only basic c++ knowledge. These are the questions I ask myself:
Doesn't the struct usb_device need some definitions of components?
Is there a data type urb_t, I presume it doesn't exist by default, so is it defined in the lines before?
