HOW TO INSTALL GFORTRAN ON UBUNTU 16.04 CODE
Not only are these extension not recognized by all compilers, but Fortran 2008 code can be still be written as fixed-form source it’s still part of that standard. For older, fixed-form code, such as FORTRAN 77, the. f08 are used for modern, free-form source code conforming to the Fortran 90, Fortran 95, Fortran 2003, and Fortran 2008 standards, respectively. This may seem odd at first, but there are good reasons for this: an operating system might use a database of some sort to store all information in, so if the standard prescribed files on disk as the medium, it would exclude such (pre-command line/terminal) systems. More specifically, there can be no code outside the program, subroutine, function, or (sub)module, whence the ISO Fortran standard itself does not define any extension, it does not even prescribe the use of files on disk to represent the source code. Second, unlike Java, C/C++, Python, etc, there is no concept of a file as an organizational unit for the source code in FORTRAN/Fortran.
HOW TO INSTALL GFORTRAN ON UBUNTU 16.04 MAC OS
In fact, Mac OS doesn't even distinguish between main.f or MAIN.F, they are in fact equivalent. Now, while the notion of a "file extension" is ubiquitous on Windows platforms, other platforms such as UNIX/Linux/Mac OS do not attach any special meaning to the last bit of a file name. F90 (on UNIX/Linux) for fixed-form or free-form source code that must be preprocessed in a C/C++ like style using Macros, e.g., #define BLAH_BLAH = 42. In a nutshell, the common conventions are. for extension, the compiler should process correctly if it is conforming fixed form source, be it 77, 90, 95, 2008, whatever.
Fortran 95 is the standard people should care about. Certsin less common extensions can be enabled by special flags. It enables certain common extensions to the standard. But it is normally good for programs in Fortran 90 and 95 and even some in 77. For example the automatic re-allocation on assignment. Before you do it try installing gfortran 4.8.5 in Ubuntu 16.04 with the command sudo apt install gfortran-4.8 and test if it can do what you need it to do. Some of the default settings are different from Fortran 90 and 95. You could install an Ubuntu 14.04 guest OS in VirtualBox and run gfortran 4.8.4 that way.
Gfortran, in the default mode gnu is actually close to a Fortran 2003 or 2008 compiler. It would mostly just enable those errors and oversights in the standard and disable just a few features. Many times someone says he is using Fortran 90 he is in fact using something else.įortran 90 and Fortran 95 are so close that there is even no option to enable Fortran 90 in compilers. For example, it allowed existence of undefined allocation ststus. It had serious deficiencies, especially with allocatables, that were fixed by Fortran 95.
