I began by choosing GNU => the BUILD and RUN ran with no problemīut it is not the same with the two other compilers, because by clicking on "OK" for their choice, I have a message: " couldn't find compile executable in your configured search for the G95 (or PGI) fortran compile " To test first of all a simple example using the FORTRAN, I noticed with pleasure that the panel " Global Compiler Settings " allows to select among numerous options that of the choice of a Fortran compiler :
So, I have downloaded yesterday the version 17.12 and I installed it with no problem on my HP/WINDOWS computer. Remark: This distribution of Fortran was obtained from the now defunct website but the instructions should work (last checked on January 7, 2012).Wishing to complete a big program of astronomical calculations written several years ago in FORTRAN 90, I thought of using the " CODE-BLOCKS " environment to benefit from its numerous advantages: IDE, forums, compilers, etc. In each window you will be working from the g77\bin directory, and you can jump from one window to the other with the click of your mouse. Perhaps the most efficient way of writing and testing a Fortran program on your home computer is to open two DOS windows, one for editing your source file with the DOS editor, and the second for compiling and running your program. You do not have to enclose the name in quotes, as you do in saving with Notepad. When you save the file, just name it whatever.f and it will automatically be saved to the g77\bin directory (by default, since that is the directory from which you opened the DOS editor). The DOS editor will open and you can type your source file. Open a DOS window, go to the g77\bin directory (as above), and enter "edit". On your home computer probably the easiest editor for creating Fortran source files is the DOS editor. (Any name you give a compiled file must end with the extension. If you want to give the compiled file a name of your own choosing, say such as hello.exe, then compile it with the command To run this file from the g77\bin directory just enter Then, to compile for example the file hello.f, enterįortran creates a compiled file that it names a.exe. To get into this directory from a DOS prompt, enter
It is simplest to save all your Fortran programs to this same directory. The three files will unzip into a g77 directory, divided into three subdirectories named g77\bin, g77\lib, and g77\doc.įortran is run from the g77\bin directory. Next unzip the three zipped files by entering in succession
Get a command prompt and go to the root directory on your c drive by enteringĬhange the name of unzip.zip to unzip.exe by entering To download and install GNU Fortran into Windows, download into your c:\ directory the four files
