[Digikam-users] Setup of OpenCV 2.4.9

[eric]

Hello,

I've check and modify an old script to build and install OpenCV-2.4.9:

http://askubuntu.com/questions/346264/does-the-version-of-opencv-shipped-with-12-04-support-v4l2

The modify script for openCV 2.4.9 on ubuntu 12.04 :

1 - create an empty folder in you home directory
2 - create the script in the empty folder and make it executable
3 - launch it with ./nameofscript.sh 


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

I have check it with TAR and repository digikam 4.1.0 : no trouble.
(except for SSE3, I work with a pentium M - see comments in script)

If you use kubuntu-backport, you will have to remove OpenCV 2.4.5
packages before compiling digikam 4.1.0.

If you want tu use internal libpgf, you have to uninstall libpgf package
too, before compiling digikam.

Greatings,

Eric
