If you build Ferret from these source files:

1. We highly recommend you build and use PyFerret (see: https://github.com/NOAA-PMEL/PyFerret) instead of Ferret. PyFerret provides publication-quality graphics and much more funtionality while still maintaining the Ferret command prompt and compatibility with existing Ferret scripts. PyFerret uses Qt for displayed graphics, removing the need for X-Windows software libraries and header files for Ferret builds. PyFerret maintains this Ferret repository as an upstream source, so updates to Ferret will also be found in the "Ferret engine" within PyFerret.

2. If you still wish to build Ferret, more information on building Ferret can be found in the README_build_ferret and the README_ferret_mac_homebrew.md files in this repository. This second file can also provide some useful information about building Ferret on Linux and Unix-type systems.

3. The site_specific.mk.in and external_functions/ef_utilites/site_specific.mk.in files in the repository must be copied to files without the .in extensions, and the contents of these site_specific.mk files edited for your system configuration. The site_specific.mk files will be ignored by git (the name was added to .gitignore) so your customized configuration files will not be added to your repository if you have cloned this repository.

4. The definitions of CC, FC, and LD (the last only for building external functions written in Fortran) were moved to the site_specific.mk.in files. (These were previously defined in the platform_specific.mk.* files.) If you already have customized site_specific.mk files, please appropriately updated your customized files with these additional definitions.
