Public bug reported: Hello.
If you look at the instruction of installation of binary or source code compilation from the original source, ncl will traditionally install in /usr/local/ncl Then environment NCARG_ROOT is set to /usr/local/ncl. The ncl folder contains bin, lib and include folders. Various ncl scripts will call upon this environment NCARG_ROOT to load the various libraries and supporting scripts from the ncl package installation. There are also programs like RIP that depends on the classic installation path of ncl. Installing ncl will install the ncl components in various places, that is: /usr/bin /usr/lib/ncarg /usr/include/ncarg /usr/share/ncarg Even more messy is that there is a there is a folder inside /usr/share/ncarg/ and /usr/lib/ncarg that will just point at each other and creating endless loop. The fix to this messy problem and making sure that the ncl installation will work For the traditional lib directory and sub directories. sudo mkdir /usr/local/ncl sudo mkdir /usr/local/ncl/lib sudo ln -sf /lib/x86_64-linux-gnu/ncarg/* /usr/local/ncl/lib/. sudo mkdir /usr/local/ncl/lib/ncarg sudo ln -sf /usr/share/ncarg/* /usr/local/ncl/lib/ncarg/. sudo mkdir /usr/local/ncl/include sudo mkdir /usr/local/ncl/include/ncarg sudo ln -sf /usr/include/ncarg* /usr/local/ncl/include/ncarg/. For the traditional include directory and sub directories. Optional, remove the link loop sudo rm /usr/share/ncarg/ncarg I think there's no need to link the bin directory Then add in ~./bashrc export NCARG_ROOT=/usr/local/ncl Now all typical ncl scripts, whether written by ncl developers themselves (as example) or by ncl users will work. Programs that utilise ncl such as RIP would also work now. This is important, as ncl development has been discontinued. The binary installation provided by ncl websites still depends on libgfortran3 which has long been discontinued. ** Affects: ncl (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889040 Title: Messy ncl installation in 20.04 and fix To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ncl/+bug/1889040/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
