[netCDF #ZUE-161248]: Configure error : C compiler can not create executables

Hello Cristian,

Thanks for reaching out; from the config.log file you provided, it appears that 
the linker is failing to find -lz and -lcurl.  This is unusual; would you try 
configuring netCDF as follows? 

    $ CFLAGS="-O3 $(nc-config --cflags)" FFLAGS="-O3" LDFLAGS=$(nc-config 
--libs) CC=gcc FC=gfortran ./configure --prefix=/opt/netcdf/4.7.4

If you installed netCDF-C 4.7.4 as a static library, you may need to run the 
following command instead:
   
    $ CFLAGS="-O3 $(nc-config --cflags)" FFLAGS="-O3" LDFLAGS=$(nc-config 
--libs --static) CC=gcc FC=gfortran ./configure --prefix=/opt/netcdf/4.7.4

This assumes that `nc-config` is on your binary path.  If it is not, replace 
'nc-config' in the previous commands with '/opt/netcdf/4.7.4/bin/nc-config'

Let us know if this fixes the issue, or if the symptoms change as a result.  

Thanks, have a great day,

-Ward
