David -
Did you check if maybe you need to use icc (the intel c compiler) as your c
compiler? If so, define CC as icc in the machine file. I by default define
CC as gcc (the GNU c compiler, of course) because most folks have that, and
it interoperates fine with ifc. Perhaps it is out on your systems as
/usr/bin/cc? Or perhaps you do have the c compiler, but there is a problem
with the make being used? I have not checked a bunch of makes out, but the
Makefile structure and Compile script are pretty much "stock amber".
Regarding erfc(), I know that is available in the c math lib on a lot of
systems; I have just always used the amber defaults to get the code in the
system-specific diretories under Machines, avoiding any potential
compatibility issues. I don't know what the speed or precisions issues, if
any, are (but once you find the c compiler, you can use whichever you
prefer).
