If you want to generate cascade with OpenCV training tools, you should be ready for waiting plenty of time. For example, on training set: 3000 positive / 5000 negative, it takes about 6 days! to get cascade for face detection. I wanted to generate many cascades with different training sets, also I added my own features to standart OpenCV’s ones and refactor algorithms a little bit. So waiting for 6 days to understand, that your cascade does nothing good =) was really anoying. To reduce time, I chose paralleling methods.

Compiling OpenCV part 2
Compiling without profiling
This time I compiled OpenCV library on Debian Linux installation.
I used VMWare 6.5 and Debian OS linux distribution.
I setup Virtual Machine to allocate 10GB hard drive space and 512 MB of system memory.
I setup the latest version of CodeSourcery G++ toolchain (version arm-2008q3-72-arm-none-linux-gnueabi) downloaded from http://www.codesourcery.com/sgpp/lite/arm. The installation dir was /opt/crosstool/codesourcery
