[Playerstage-developers] videodev2.h issue

[Radu B. R. <ru...@cs...>]

Just a reminder if you are trying to compile and install from CVS, the 
camerauvc driver can issue a...

configure: WARNING: linux/videodev2.h: present but cannot be compiled
configure: WARNING: linux/videodev2.h:     check for missing prerequisite headers?
configure: WARNING: linux/videodev2.h: see the Autoconf documentation
configure: WARNING: linux/videodev2.h:     section "Present But Cannot Be 
Compiled"
configure: WARNING: linux/videodev2.h: proceeding with the preprocessor's result
configure: WARNING: linux/videodev2.h: in the future, the compiler will take 
precedence
...

I spent quite some time today, trying to debug this. It is basically an issue 
that I found (at least) in Debian, while creating a jail with unstable. For 
some reason, the /usr/src/linux/videodev2.h (which is a part of 
linux-kernel-headers) is missing an "#include <asm/types.h>". Be sure to 
insert that in, if you get the above configuration error.

Thanks to Raymond (the camerauvc author), who is sitting next to me now, for 
nailing this one. Hopefully your linux won't complain about it, but just in 
case it does...

Best,
Radu (and Raymond).
