Can't find or link to the hdf5 library

[MuzafarWani]

I am trying to install netcdf-c-4.9.0
I installed the prerequisites hdf5 and zlib but when I try to install netcdf it throws error
checking for library containing H5Fflush... no
I am using the below command to install
CPPFLAGS='-I${hdf5dir}/include -I${zdir}/include ' LDFLAGS='-L${hdf5dir}/lib -L${zdir}/lib ' ./configure --prefix=/home/muzafar/Downloads/installs/netcdf
and hdf5dir,zdir, are rest to respective installation directories.
Also I have set the LD_LIBRARY_PATH to /home/muzafar/Downloads/installs/hdf5/lib:
I am attaching a confg.log
can you please let me know what is the issue with my installation.
config.log

What version of hdf5 are you using? Can you provide the libhdf5.settings file from your installation?

libhdf5_settings.txt
I am using hdf5 version 1.12.2

Thank you. From the config.log file you provided, we can see that the environmental variables you're setting aren't being properly picked up:

AM_CFLAGS=''
AM_CPPFLAGS=''
AM_DEFAULT_V='$(AM_DEFAULT_VERBOSITY)'
AM_DEFAULT_VERBOSITY='1'
AM_DISTCHECK_CONFIGURE_FLAGS += --disable-valgrind
AM_DISTCHECK_CONFIGURE_FLAGS ?=
AM_LDFLAGS=''
AM_V='$(V)'

This is puzzling. I also notice now that you're using single quotes, ', instead of double quotes ", when defining CPPFLAGS, etc. Single quotes will prevent the expansion of environmental variables (like ${hdf5dir}). Try replacing the single quotes with double quotes, and let us know what happens.

[WardF]

To illustrate the point above, consider the following example of single quotes vs. double quotes:

wfisher@shetland:~/Desktop/gitprojects/netcdf-c$ A=B echo '$A'
$A
wfisher@shetland:~/Desktop/gitprojects/netcdf-c$ A=B echo "$A"
B
wfisher@shetland:~/Desktop/gitprojects/netcdf-c$
