Question

I would like to call C++ functions in python which return uBLAS vector/matrices.
There is a package to do this called PyUblas,
but am having trouble getting this to work in Ubuntu.

Can anyone walk me through the steps to get this sample to work?

Also, I am somewhat confused with the installation instructions. I did not follow the instructions to install boost and numpy since I have already installed them from the Ubuntu repositories.

I guess that wasn’t so hard. Here’s what I did to run the small sample on the website and in test/samply.py.

After downloading and unpacking PyUblas, and having the necessary libraries installed, cd into PyUblas-VERSION

./configure.py --help
./configure.py --some-options
sudo python setup.py install
cd test/
g++ -I/usr/include/python2.7 -fPIC -g -fpic -shared sample_ext.cpp -lboost_python -lpython2.7 -o sample_ext.so
python sample.py
