[netCDF #JIL-655966]: compile netcdf with pgi

Hi,

By choosing "config.log" as the name of the file in which to put
the output from the configure script, you had the bad luck of
choosing the same file name as configure uses to log its detailed
internal tests.  So the result is both kinds of information got
written into the same file, but it looks like your configure script
completed, because it ended with:

  configure: exit 0

Most of the other error messages you see in there occur while configure
is testing the environment, and are expected.  However, this is not, and
indicates a problem in your PGI compilation environment, such as not
installing the header files correctly:

  configure:26581: checking for IEEE floating point format
 ...
  configure:26639: ./conftest
  configure:26643: $? = 1
  configure: program exited with status 1
  configure: failed program was:
 ...
  configure:26659: result: no

This probably means the /usr/include/float.h header file which is a
required C Standard Library header either doesn't have the required
macro definitions or defines some floating-point properties that do
not conform to the IEEE floating point standard or any other floating
point standard that netCDF can handle.  Your 64-bit x86 platform ought
to use IEEE floating point arithmetic, so until you can successfully
compile (with pgcc) and run the small C program attached to produce some
output other than "not IEEE", your compilation environment can't be used
for building and installing netCDF.

I hope this helps ...
