what i meant is, that a header file is not included by the videoV4L2.cpp
file you are trying to compile.

doing
$ man fstat
(because the compile complains about "fstat" being undeclared)
i am told to include
       #include <sys/types.h>
       #include <sys/stat.h>
       #include <unistd.h>
most likely "sys/stat.h" will do.

anyhow, in gem-0.92-3 there is NO Gem/src/plugins/videoV4L2.cpp file.
this only exists in the current SVN trunk.
so it seems you are editing one file and then trying to compile another
one - no wonder you still get errors.

obviously the correct file is
/home/tim/Downloads/gem-0.92-3/src/Pixes/videoV4L2.cpp



alternatively you could also try to compile the current SVN tree with
artoolkit, but it might not work.
if it does work, then you don't have to compile the entire Gem at all,
but simply go to extra/pix_artoolkit and compile the one object.

(i don't think you can use pix_artoolkit compiled for Gem-0.93(svn) with
Gem-0.92-3)
