Issues when compiling OpenCV 3 RC1 in Ubuntu 14.04


Error:

numpy ImportError: /usr/lib/liblapack.so.3: undefined symbol: ATL_chemv


Fix:

Lapack package is available in ubuntu software centre... Search for liblapack... Install all the files... Also search for libblas as blas files are essential for running a lapack subroutine. Install all the libblas files.

Using linux command line this can be done by typing the following commands:
sudo apt-get install libblas3gf
sudo apt-get install libblas-doc
sudo apt-get install libblas-dev
sudo apt-get install liblapack3gf
sudo apt-get install liblapack-doc
sudo apt-get install liblapack-dev
