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.

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).  :)

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.

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).
