Would you kindly send the following information: 1) the command you used to execute the `configure` script 2) the full output from`configure` command you ran in 1) 3) the full output from `make` command 4) the full output from `make check`command > > i cannot find the software. > [root@localhost ~]# which netcdf > /usr/bin/which: no netcdf in > (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin) The `which` command is searching your $PATH to see if something called netcdf lives there, but it can't find it because you haven't installed it yet. You've built it (or parts of it), and you've tested it in your build directory (/home/netcdf-4.1.2/), but you haven't put it in a place where you system can 'see' it yet (which is good, given that some tests area failing).
