Running Amber on Sun OS

All of Amber (except for pmemd, which might be easily ported?) will compile and run on SunOS. Note that a Fortran 90 compiler is distributed with SunOS. The Sun Performance Library is a viable replacement for source compiled BLAS and LAPACK routines; support for the Sun Performance Library is included in Amber's configure.

Known Problems

• In Amber 8 the -q option of grep (which designates Quiet and produces no output) is used in src/Makefile, benchmarks/Makefile, and test/sugarlp/Run.sugarlp. Unfortunately, SunOS has several greps, and the grep that supports -q may not be first in ones PATH. /usr/xpg4/bin/grep does support -q, and the recommendation is that users ensure that this grep is executed by the command grep. Alternatively, one could remove the -q option from the grep commands and ignore the spurious output (or with a little more UNIX savvy redirect the grep output to the null device).

• The /usr/ccs/bin/m4 macro processor has a push-back buffer of default size 4096. This is too small to build xleap:
  m4:xaLeap.rm4:993 pushed back more than 4096 chars
  This is Amber8 bugfix.39.

• The archive utility should be in ones PATH. There are a couple:
  /usr/xpg4/bin/ar
/usr/ccs/bin/ar

• The archive utility command invocation by make may be missing whitespace:
  ar rvsys.a sys.o wallclock.o
  It should be
  ar rv sys.a sys.o wallclock.o
  This is related to the version of make. I'm investigating this; for now:

  Here's the way I do it.  I think this works with all flavors of
  make, and you only need to change one file.  In config.h, do the
  following where AR is defined:
  
  ANEMPTYMACRO=
  AR=ar rv $(ANEMPTYMACRO)
