Greetings Liang, /Developer/usr/bin/gcc is an old path, but it seems to be picking the right gcc version for you (which is interesting). What is the output of xcode-select -print-path It should be /Applications/Xcode.app/Contents/Developer If not, run this command to select the correct instance of Xcode: sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer Then try running configure again. Also, if you are really only interested in the classic library, then make sure to add --disable-netcdf-4 to the flags in your configure command: ./configure --prefix=/Users/liangguo/Applications --disable-netcdf-4 --disable-dap Let me know how this goes for you. If none of these things work, could you send me the output of the command env? Cheers! Sean > Hi Sean, > > I update the Xcode to the latest version (4.3.2) from apple store.
