In recent studies of GIS algorithms, FORTRAN language is needed. Found an open-source software gun Fortran compiler on the Internet. Of course, since it is a compiler, it compiles programs, but the editor is not included. The editor can be in text Notepad, or it can be zionedit.
First loaded with the gun Fortran compiler, finished. Think it is a visual interface, the results in the bin directory click Gfortran.exe a flash, understand that this should be executed with the cmd command.
First, enter ' cmd ' in ' Run ' to enter the DOS command window. Then switch to the Gfortran executable directory of the hard drive. G:--CD Gfortran and CD bin.
Next, enter Gcc-v and gfortran-v to see if the version number appears.
