There is an older version in the stable Debian 7.6 repositories, opencv 2.3.1


2.4.9 can be backported from the source code in Jessie (Debian Testing) and recompiled against the Wheezy libraries into packages without much trouble. I've currently only done this for my own use on amd64, so I could play around with packaging webcamoid:

http://opendesktop.org/content/show.php ... ent=144796

But I can backport and upload i386 packages also if you wish to try them out. The other choice is to request they be done for wheezy-backports.

You end up with the stock opencv and the newer version installed at the same time, which is OK because they have the version in the package name. You can have only one version of the -dev packages installed at the same time though, so you have to decide which ones you want installed if you wish to compile against the stock version or 2.4.9.

Just run the following commands, and it should work just fine.

Code: Select all

arch=$(uname -m)
if [ "$arch" == "i686" -o "$arch" == "i386" -o "$arch" == "i486" -o "$arch" == "i586" ]; then
flag=1
else
flag=0
fi
