Message: 60605    I have gone through the previous threads regarding opencv. I followed the instructions. I get the following error. Am using uclinuxR2_RC2 and opencv version 1. The host is Mandriva distribution of linux.

Also upon ./configure --build=i686-pc-linux-gnu --host=bfin-uclinux i get the following message:

The INSTALL file from opencv says that I should have the following stuff: libpng, zlib, libjpeg, libtiff, libjasper with development files. + Python 2.3, 2.4 or 2.5 with headers installed (developer package) + libavcodec, etc. from ffmpeg 0.4.9-pre1 or later + headers. Earlier versions do not work with OpenCV because of different API. libavcodec is LGPL software, so to use it with non-GPL software (such as OpenCV) you need to build and use a _shared_ library libavcodec.so.*: get ffmpeg from ffmpeg.sourceforge.net I guess the error message might be cos I dont have all the libraries. Would I have to get these libraries for the host machine or for uclinux and have it compiled for uclinux before I compile uclinux?

you should be using the latest release (2008R1.5), not an old one (2006R2)

The problem is that am using a particular hardware for which the last stable release was 2006R2. Hence I need opencv to be compiled for this kernel. Is there any other solution?

feel free to hack the sources.  things have already been fixed in 2008R1.5.
