This may work if you manually install the dependencies, which are (on
Ubuntu) "liblapack-dev" and "libblas-dev". (I suggest the developer
packages here because you also tried installation from source.)

I would try downloading the MADlib source again from:
https://github.com/madlib/madlib/zipball/v0.2beta
The directories deploy/PackageMaker and deploy/RPM should definitely
be there:
https://github.com/madlib/madlib/tree/v0.2beta/deploy

Unless you have specific needs, I would rather go with the Ubuntu-
provided packages (see above).

Re: Problems with the ubuntu madlib installt

Hi Florian,

I have finally installed MADlib on Ubuntu. Thanks for providing the
deploy directories. However there were some other issues that I
faced :-
I installed a C library of postgresql through this package postgresql-
server-dev.

Also in the <madlib folder>/doc/src/sql.yy file I included sting.h
library because in line no. 512 there was std::strcmp and std
namespace does not have strcmp function so I removd std here. Other
errors were file permission errors and dependency errors like m4 pre
processor, gfortran, lapack/blas etc.

The installation is complete, I just got an error in the output of the
built in k means algorithm.

I created a table in a postgres database with attributes pid and
position and of type integer and float array respectively. When I run
the algorithm it gives this error

 select MADlib.kmeans(
'public.test', 3, 1, 'testrun', 'testab');
INFO:  ('Started kmeans_run() with parameters:',)
INFO:  (' * k = 3 (number of centroids)',)
INFO:  (' * input_table = public.test',)
INFO:  (' * goodness = 1 (GOF test on)',)
INFO:  (' * run_id = testrun',)
INFO:  (' * output_schema = testab',)
NOTICE:  table "kmeans_out_points_testrun" does not exist, skipping

Re: Problems with the ubuntu madlib installt

Dhruv, try setting your search path to include madlib schema, e.g.: "set 
search_path=madlib,..."

Re: Installation failed on CentOS 5

Carlo, please follow the instructions for our Beta version below:
https://github.com/madlib/madlib/wiki/Installation-Guide-%28v0.2beta%29

We do not have enough resources to support Alpha at this point.
