And a site note. I would recommend to update scalapack to 2.0.2. That version 
has blacs included in the installation, so you do not need to include a library 
yourself.

Hi Bruce 



Such an error means that linking to the blacs library has not completed 
succesfully. 
Please provide your arch.make if we are to help you. 


A common error in that link step is that the blacs library is placed wrong in 
the linking of libraries. Try and read the following basic introduction to the 
linking step: 
http://www.network-theory.co.uk/docs/gccintro/gccintro_18.html 


Furthermore know that Scalapack relies on blacs. Thus blacs should be linked 
last. 


Kind regards Nick

I have tried building SIESTA using a wide variety of build procedures found on 
various websites. 
Is there a website with a build FAQ? My latest failure results in 
_blacs_gridinfo_ being reported as 
undefined in the SIESTA link. 

Software configuration 
UBUNTU 12.4 desktop 
ATLAS: retrieved via apt-get located now in /usr/lib/atlas 
BLAS: latest from netlib 
LAPACK: version 3.2 
BLACS: mpiblacs and mpiblacs-patch03 
SCALAPACK: version 1.8.0 
SIESTA: version 3.1 
OPENMPI: version 1.6.1 


My test machine configuration is an AMD FX-62 dual core and 8 GB of RAM. I'm 
working to better 
understand the build process so I can build for a 
multiprocessor/multicore/multinode network configuration. 


Thank you in advance, 

-Bruce
