While running an example from chap8,I am getting this error.
Traceback (most recent call last):
File "sdp", line 5, in <module>
from cvxopt import matrix, solvers
File "/usr/local/lib/python2.6/site-packages/cvxopt/__init__.py",
line 30, in <module>
import base
ImportError: /usr/local/lib/python2.6/site-packages/cvxopt/base.so:
undefined symbol: dgemv_
Any answer is appreciated.

this means there was a problem with BLAS. What platform are you
compiling CVXOPT for?
On a Linux platform it could be that you need to install development
versions of the BLAS and LAPACK libraries (in addition to the libraries
themselves). On Windows, it's possibly that you need to change the
build variable 'BLAS_NOUNDERSCORES' in the CVXOPT installation
script 'src/setup.py'.

That depends on the version of linux. On Debian/Ubuntu, you use
the package manager aptitude.
the package manager aptitude.
Linking against BLAS/LAPACK or ATLAS is the most frequently
reported problem for building CVXOPT, but if you have
the right libraries installed it is actually straightforward.
The prerequisites may vary from platform to platform, and we
cannot help you with those (unless you use Ubuntu, which
we use for developing CVXOPT).
Is it not possible for you to use a precompiled version of CVXOPT?
As we mention on the CVXOPT homepage, such versions are available
on virtually all larger Linux distributions...

I tried it on red hat enterprise linux for which no precompiled
version of cvxopt is available.
Ok.
I will try on ubuntu.

I am facing the same problem in ubuntu also.Could you please give me
the link of ATLAS & python packages required for cvxopt installation.

On Ubuntu you can install cvxopt directly from the terminal:
sudo apt-get install python-cvxopt
If this for some reason does not work or if you want to compile cvxopt
yourself, you will need libblas-dev and liblapack-dev. You can install
these libraries from the terminal as follows:
sudo apt-get install liblapack-dev libblas-dev
(I'm not sure if you also need libatlas-headers and/or libatlas-base-
dev.)

On Ubuntu you can install the necessary libraries for building
CVXOPT as:
$ sudo apt-get build-dep python-cvxopt
After that it should be easy to compile CVXOPT from source.
But I would recommend using the binary version shipped
with Ubuntu.
