[netCDF #FTM-837716]: error compiling - z library

Hi John,

Just a guess, but it's possible that either you're trying to compile in the 
32-bit model (in
which case the lib64 library would not be usable, even though you explicitly 
specify to look
there).  Make sure you either specify -m64 as a compiler/linker flag or that 
the default for
the compiler you're using is 64-bit.

Another possibility is that a 32-bit libz shared library is installed in the 
path that your system
is configured to search, and it's looking instead for a 64-bit library.  You 
could use ldconfig(8) to
set the load paths correctly in /etc/ld.so.conf for Linux systems or the 
equivalent for other
platforms.  Also you could test if its a shared library path problem by seeing 
if setting
LD_LIBRARY_PATH to a directory containing the library for the right bitlength 
model makes
things work as expected.
