I've tried to use pix_video with the driver 1 message, but it don't work...

driverID (1) must not exceed 1 GEM: Start rendering pix_videoNEW: starting transfer closing video pix_texture: not using client storage

The console output is /dev/video0: No such file or directory

I thought that gem is using dv1394 to connect to firewire cameras. I've tried to create the node above with mknod -m 666 /dv/video0 c 81 0 is this right for PAL? Or have i just forgotten some messages to [pix_video] i've only sent the [driver 1( message to it.

Hallo,

hm ... maybe you also need a /dev/ieee1394 - I don't really remember how I did it ...

So id tried to make device nodes for dv1394 and ieee1394 by mknod -m 666 /dev/dv1394 c 171 34 mknod -m 666 /dev/ieee1394/dv/host0/PAL/in c 171 34

...

Or have i just forgotten some messages to [pix_video] i've only sent the [driver 1( message to it.

normally not - but just try ...

I've tried to send many different messages to [pix_video] but it doesn't work. So, i downloaded the source from gem 0.90 and tried to read it (I'm not familiar with C/C++) and there is one thing which i have detected:

if gem is recognizing that there is dv it should write the message “ieee1394 for linux”, but it doesn't

The message only appears if HAVE_DV is defined, and HAVE_DV when HAVE_LIBDV is defined but i couldn't find where HAVE_LIBDV is defined in the source, and most interesting thing why HAVE_LIBDV or rather HAVE_DV is not defined...

Hallo,

you don't need to hack the code to define that, just use the configure script (look ./configure --help for all options) there should be an option for ieee1394 or dv or something like that ...

I've installed Gem with apt-get install before so i don't have to use the

so you are on debian ?

./configure script before. I've tried to use it by typing

./configure --with-ieee1394

but there is something wrong with opengl

loading cache ./config.cache HEAD: /usr/include /usr/local/include ../../../GemLibs/

checking for X... no checking for MMX... checking MMX found... checking for main in -lX11... no checking for main in -lXext... no checking for XF86VidModeGetAllModeLines in -lXxf86vm... no

you will need the X development (xlibs-dev) libraries

if you are running etch/sid you also need to install the libxxf86vm-dev package.

checking for sin in -lm... yes checking for main in -lz... no checking for glInitNames in -lGL... yes checking for gluLookAt in -lGLU... no checking for gluLookAt in -lMesaGLU... no incomplete OpenGL (no GLU)

What is GLU and how can i make it run? In the ./config help i didn't find anything about that.

well, the README.build file says, that the prerequisites are (among others) "openGL + GLU" and it gives a link to the mesa homepage.

the first hit on http://www.google.at/search?q=opengl+glu gives me "GLU is the OpenGL Utility Library"; you have to install it (and also its dev-package).

basically, for each package that is needed by Gem you also have to install the dev-package (since you are compiling)

Kubuntu.

Ok i've installed all packages which are needed by Gem but there is a Problem with dv1394.h file. The Compiler doesn't find it. So i've tried to ./configure the makefile with –includedir=/usr/src/linux/drivers/ieee1394 the header file is there... My Question is now: how can i reset the makefile,that the compiler knows the new directory??

ok; this is a problem due to a change in packaging of libdv-dev (after gem-0.90 was released)

there are 2 possibilities:

1. checkout the latest CVS-version of Gem; this has been adapted to

newer packages 2) tweak your makefiles, e.g. by editing it or using configure; you will then have to do a "make clean; make" (probably _not_ "make distclean")

the CVS-version of Gem also has a rewritten build system (now in src/ instead of src/Gnu/) which handles changes in dependencies correctly.
