Hi,

I'm experimenting with the build script on AV Linux/Debian Squeeze 32bit, If I disable frei0r in the script the build succeeds however with frei0r enabled the script fails with this:

To my knowledge all dev libs are installed. Help or advice appreciated!

Hi,

Problem caused by OpenCV 2.1 on Debian Squeeze being too old. Building opencv 2.4.2 from source fixed the compilation error, thread marked as solved.
