thanks hans for this indication
this is the correct flag to compile it with v4l2?!
--with-libv4l2-includes=/usr/lib/libv4l2.so
the package builts but still i'm gettin
error: [pix_video]: could not find a backend for driver 'v4l2'
i also tried a gem solo & make spits this error:
recordQT4L.cpp -o ../Objects/recordQT4L.o
recordQT4L.cpp: In function ‘lqt_file_type_t guess_qtformat(const char*)’:
recordQT4L.cpp:96: error: invalid conversion from ‘const char*’ to ‘char*’
make[1]: *** [recordQT4L.o] Error 1
make[1]: Leaving directory `/home/olsen/pd/pd-extended/Gem/src/Pixes'
make: *** [Pixes] Error 2
same with gem 0.92-1
recordQT4L.cpp: In function ‘lqt_file_type_t guess_qtformat(const char*)’:

make[1]: Leaving directory `/home/olsen/pd/extra/0.92-1/Gem/src/Pixes'
make: *** [Pixes] Error 2
with gem0.92svn i stuck at the configure:
./configure: line 3005: syntax error near unexpected token `PIC,'
./configure: line 3005: `GEM_ARG_ENABLE(PIC, PositionIndependentCode
(potentially slower))'

hi
thanks IOhannes for the help. i installed libv4l-dev & recompiled the
package but i'm not getting the v4l2 support, as i do not know in the
pd-extended automation how to do the gem configure with libv4l-support...
greets

it installed wonderfully on my eeepc901 and pd says gem 0.92.1 from oct

when trying out pix_video it starts with video driver 0: video4linux

now, when i send a message "driver v4l2" console gives: could not

the webcam is otherwise working fine (tested with cheese)
anyone got an idea?
simple: the version of Gem you are using has been compiled without
libv4l support.
whoever built the package has either not enabled libv4l-support (there
is a new flag in Gem's configure called --without-ALL which disables
everything so you have to manually re-enable whatever you want; this is
meant for package-maintainers so they have better control about what
features the package will have) or there was no libv4l-dev installed on
the build machine.
solutions:
- build Gem yourself and make sure that you have all relevant packages
installed (in your case, don't forget libv4l-dev)
- ask the person who built your package to enable libv4l
