installing opencv on ubuntu

[iochinome]

hey guys, so i am trying to install opencv on ubuntu. i have been following the directions exactly as given in the readme, and all goes well until i enter sudo make install, and get this error:


CMake Error at cmake_install.cmake:61 (FILE):
file Internal CMake error when trying to open file:
/home/iochinome/workspace/trunk/opencv/release/install_manifest.txt for writing.

any ideas on what is going wrong? installations are really not my specialty... thanks!

There is no need to compile opencv. Its available in Universe repository. You should install it through package manager only.
Which version of Ubuntu are you using?

hey guys, so i am trying to install opencv on ubuntu.

There are a number of HowTos that can be found online for installing opencv under ubuntu, but I'd recommend enabling the correct repositories and then using either synaptic or apt to install it. Doing so should pickup all the dependencies that it needs and simply the overall process for you.

If needed, the ubuntu wiki has a couple of nice guides for using synaptic and apt.

hmm... that is really weird! i have all of the opencv files installed, as you instructed, by using synaptic package manager. (all of the files that show up under a search for 'opencv' show up as green in synaptic, and i had installed them)

but even now, when i try to compile my opencv programs, it does not work- it returns the error that there is 'no such file or directory' for either opencv.h or highgui.h ... and so i did a quick
$locate highgui.h
and it existed in /usr/include/opencv/highgui.h
but, for
$locate opencv.h
it returned nothing. what is going on here?

thanks guys... installations arent my strong suit! much appreciated-
