Hi,

It seems nobody having this problem? No one replies at
least why, so I just want to add one more case of
compiling error. Exactly the same message as yours.

RE: Unable to compile 2.5.4: "control reaches end of non-void functionm"

[J.S.S.]

I have this same problem on both my laptop and my testbox.  It happens
everytime and I have yet to compile 2.5.4 successfully.  Although, I suspect
it's in my config file - I'm just using an old config file I used for my
2.4.17 kernel which works just fine.

If it is in processor.h, search the archives. There was a patch for this
submitted to the list about a week ago.

USB device driver

[Sanjeev Lakshmanan]

Hi all

I need to develop a USB device driver for a custom
made switch. I shall give a brief description.

 The switch (which is connected to the USB port of a
Linux box running REdHat 7.1) has four RJ 45
connectors for ethernet cables and it needs to
exchange data packets of size 8 bytes every .5
seconds. The Transmit ethernet port(1,2,3,4) and
Receive ethernet port(1,2,3,4) need to be selected for
each transfer and the data packet which is to be sent
out and received on those ports changes accordingly.

Please let me know how I can start off writing the
code for  this driver.

Also please let me know if there are any SIMILAR
device drivers already developed and available.

I am aware of the files
usr/src/linux/drivers/usb/usb.*
but as I have no prior experience with device drivers,
I am unable to start off.

Regards,
Sanjeev.

RE: Unable to compile 2.5.4: "control reaches end of non-void functionm"

[J.S.S.]

Got it. Fixed it.
Still getting the video.o compile problem, but this hasn't been fixed yet
(although it's been discussed a bit, the outcome wasn't too clear).

Folks on LKML are pretty good about replying to people with problems, so 
whenever my posts are ignored here I start checking the archives 
(figuring that my problem has probably already been reported and dealt 
with).  :)
