QT headers not found.

[Ephemeral]

Hello,

I am trying to install v4lgrav-0.2.2, but during the ./config I get the following error :

checking for Qt... configure: error: Qt (>= Qt 3.0) (headers and libraries) not found. Please check your installation!
For more details about this problem, look at the end of config.log.


I have tried everything I could think of and installed many QT libraries, headers and all sorts of other things that looked like they could help.

I also searched a bit, and found a command to show all the QT stuff, so I'll give you my output

sudo apt-cache search libqt | grep mt

libqt3-mt-psql - PostgreSQL database driver for Qt3 (Threaded)

Any ideas?

Cheers,

That package is already installed :(

Any other suggestions?

Installed both, still the same error.
I read somewhere about files that need to be moved to the right directory or something like that, any idea?

So the configuration works, but says I don't have Video4Linux2 and then the make fails.
Any ideas?

*Edit* : I did a quick research, and this is what I found :

v4l2 on 2.6.x kernels

kernel 2.6.x already has everything included. Just enable the config options you need (i2c, video4linux and the actual driver), compile your kernel and you are done.

If you run into trouble you can check if there are updates with fixes in the patch directory.

I am using a 2.6 kernel, how can I enable i2c, video4linux and my eyetoy driver?
