[netCDF #ETZ-572888]: about zlib 1.2.5 and zlib 1.2.7

Hi Ming,

I don't think so, as long as it links successfully.

> 2. If so, can I build zlib1.2.7 at /usr/local/zlib-1.2.7 (different

Yes, though you may have to also set LD_FLAGS to get it to link correctly.
You may also have to ask WRF support, if you have WRF-related problems with
the result, but it sounds like it should work.  The netCDF library depends 
on the zlib used for building HDF5.  If you're using shared libraries and it
gets through the configure step that checks for zlib, everything should work
OK, as far as netCDF is concerned.
