[netCDF #HUH-505770]: Problem installing netCDF-c library

I looked at the config.log you sent.
The problem is in these lines:
> configure:16924: checking for library containing H5Fflush
> configure:16955: gcc -o conftest    conftest.c -lm -lz  >&5
> /tmp/ccT4Rx2z.o: In function `main':
> conftest.c:(.text+0xa): undefined reference to `H5Fflush'

For some reason, the gcc command is not using the values of CPPFLAGS
and LDFLAGS so it is not finding hdf5.
We need to find out why. Let me suggest the following to start.
1. Just before you do the ./configure command, do these commands.
        printenv CPPFLAGS
        printenv LDFLAGS
2. then execute your ./configure command.

This way we can be sure that at the point that you execute ./configure
your CPPFLAGS and LDFLAGS are correct.
