Thanks Nick. You're right they're just one library. My concern is mainly
whether SIESTA needs an explicit BLACS lib to work or it will just use
the routines embedded in th Scalapack library by default.
Best regards.

Embedded libraries does not mean that BLACS routines are deprecated,
but rather that instead of 2 libraries (BLACS and ScaLAPACK) they are
now 1 library (ScaLAPACK 2.x == ScaLAPACK 1.x + BLACS).
Hence when you link you just add the ScaLAPACK with "-lscalapack" or
however you wish to add the library.

Hello everyone,
I'm trying to build a parallel version of SIESTA and I'm using the
Scalapack installer to get the libraries I need. The problem is
that since version 2.0 the BLACS library is embedded into the
SCALAPACK lib, so I don't know whether SIESTA will work without
BLACS or not. Any hints?
Thanks in advance
Sebastian
