I'm compiling NETCDF on Linux.

After configure, make,make install, I have already install NETCDF on
/disk3/lly/lib/netcdf-4.1.3.

Then, using vim ~/.bashrc,edit: 

export DIR=/disk3/lly/lib    
export NETCDF=$DIR/netcdf-4.1.3/    
export PATH=$DIR/netcdf/bin:$PATH

And source ~/.bashrc.
But When I use which $NETCDF and which $DIR, I got this: 

>> [lly@localhost netcdf-4.1.3]$ which $NETCDF
>> /usr/bin/which: no  in (/disk3/lly/lib/netcdf-4.1.3)       
>> [lly@localhost netcdf-4.1.3]$ which $DIR
>> /usr/bin/which: /usr/bin/which: no lib in (/disk3/lly)

what are you trying to do? which tells you where binaries are located based on your search PATH, but you are passing it directories... that isn't how it works. – casey Jan 18 '16 at 3:00
    
Sorry, I was wrong. – Han Zhengzu Jan 18 '16 at 3:11
