Re: [Playerstage-users] [DRIVER PROBLEM] camerauvc -- couldn't find (at least one of) linux/types.h linux/time.h linux/videodev2.h

[Toby C. <tco...@pl...>]

What this message means is that videodev.h is present on your system but 
wont build without some other include that it cannot find.

if you make a file like

#include <linux/videodev.h>
int main(void) {return 0;}

and compile it will gcc with no flags (gcc testfile.c). You should get 
an error about not being able to find an include. Can you please post 
the error that results, if there is no error then it is a different 
problem, but lets isolate this one first...
