[vsipl++] vsipl++ installation on Cell

[Brooks Moses]

Hello,

Yes, this is the correct place to ask for help.  Thank you for
contacting us!

The GPL "Lite" version of Sourcery VSIPL++ does not include the Cell
Math Library (CML), which is required in order to use the SPUs on Cell
processors.  This is the source of the missing cml.h file, as that is
the header file for CML.  I apologize that this was not clearer in the
documentation, since CML is included in the full version of Sourcery
VSIPL++ for Cell processors.

We do offer academic pricing for Sourcery VSIPL++ including the Cell
Math Library, if you are interested.  Contact sales at codesourcery.com for
details.

Alternately, you can compile the GPL version of Sourcery VSIPL++ without
the --with-cbe-sdk configure option, which will produce a version that
works on your QS22 but only uses the PPU part of the processor.  Your
ATLAS installation looks correct, so something else (perhaps the missing
CML) may be confusing the configure script; you can look at the
config.log file to see the exact compile error that resulted in this
error message.  I suspect a similar problem is happening with the timer
as well.

Regards,
- Brooks
