Aug 06, 2019. Download gcc-gfortran-7.4.0-3-omv2015.0.x8664.rpm for Lx 3.0 from OpenMandriva Main Updates repository.

Remove download gfortran. Port over the configuration checks to use the backup and remove function. Implement a new gfortran download and installation technique. Upgrade installer accepted macos versions. Add changelog details. Remove dangling installer. Update splash screen of installer for readme. However, R calls a specific version of gfortran (4.8), so I'm kind of stuck here. I can't really upgrade to gfortran 5.0 because R won't recognize it, and gfortran 4.8 doesn't work well with my OS. Any help would be much appreciated. Sep 02, 2020 There are several options available for installing gfortran for Mac OS X, other than installing from source code. GCC Wiki I currently choose to use the relevant gfortran installer (.dmg) packages provided through the GCC Wiki (opens in new window).

Why did I install gfortran? Well, not to write Fortran programs. I tried installing SciPy using pip install scipy, and I got a message that a Fortran compiler was needed.

Install

This is how I installed gfortran on my Mac:

Visit hpc.sourceforge.net, and select a binary distribution for your version of Mac OS X, e.g. gfortran-snwleo-intel-bin.tar.gz for Snow Leopard.

Download the file and open the download directory in Terminal.

To install gfortran do the following:

Compile a hello world

Let's do a quick test that gfortran was installed.

To try compiling a small testprogram, enter the following into a file called radius.for (btw, the whitespace matters):

Compile and run the program:

Enter a number, e.g. 3, to see the area of a circle with this radius.

Uninstall

To uninstall again (warning, I haven't tried it):

or do the following to delete without prompting:

The purpose of the GNU Fortran (GFortran) project is todevelop the Fortran compiler front end and run-time librariesfor GCC, the GNU Compiler Collection. GFortran development is partof the GNU Project. We seek to bringfree number crunching to a broad spectrum of platforms and users.

In particular, the project wishes to reach users of theFortran language, be it in the scientific community, education, or commercial environments. The GFortran compiler is fully compliantwith the Fortran 95 Standard and includes legacy F77 support.In addition, a significant number of Fortran 2003 and Fortran 2008features are implemented. Please give it a try. If you encounter problems,contact us at the mailing list or file a problem report.

GFortran development follows the open development process. We dothis to attract a diverse team of developers and to ensure that GFortranworks on multiple architectures and diverse environments. We always needmore help. If you are interested in participating, please contact us atfortran@gcc.gnu.org.(Also check out our mailing lists page.)

The Wiki and Getting the Compiler

For additional info on GFortran developments, you may find theGFortran wiki useful. Anyone may contribute information to the wiki. (Neither copyrightpaperwork nor a patch review process is required.)

Gfortran For Windows 10

The GNU Project is about providing source code for its programs. For convenience, a number of people regularly build binaries for different platforms. Links to these can be found at the wiki. Most of the binary executables are the latest development snapshots of GFortran and areprovided to encourage testing. We also want new users, from studentsto masters of the art of Fortran, to try GFortran.It really is a great compiler!

Project Objectives

We strive to provide a high quality Fortran compiler that workswell on a variety of native targets. This means:

Conformance to Fortran standards, primarily Fortran 95, 2003,and 2008
Performance of executables and computational accuracy
Reasonable compile speed and cross compilation capability
Good diagnostics and debugging features
Legacy code support where practical.

Extensions in GNU Fortran

The initial goal of the GNU Fortran Project was construction of aFortran 95 compiler that complies with the ISO Fortran 95 ProgrammingLanguage standard [ISO/IEC 1539-1:1997(E)]. We are now well intoF2003 and F2008 features.The GFortranwiki and our bug trackerlist features under development or yet to be implemented. Compilercapability is quite extensive and includes nearly all g77 features.We highly encourage users to move from g77, which is no longermaintained, and start taking advantage of GFortran's modern features.Legacy g77 code will compile fine in almost all cases.

Status of Compiler and Run-time Library

We regularly update thestatusof the front end and run-time library development.

Contributing

We encourage everyone to contribute changes and help test GNU Fortran. GNU Fortran is developed onthe mainline of GCC and has been part of the compiler collectionsince the 4.0.0 release.

Contributions will be reviewed by at least one of the followingpeople:

Under the rules specified below:

All normalrequirements for patch submission (assignment of copyright tothe FSF, testing, ChangeLog entries, etc) still apply, andreviewers should ensure that these have been met before approvingchanges.
Approval should be necessary forpatches which don't fall under the obvious rule. So, with the approver listput in place, everybody (except maintainers) should still seek approval for his/her patches. We have found the mutual peer review process really works well.
Patches should only be reviewed bypeople who know the affected parts of the compiler. (i.e. thereviewer has to be sure he/she knows stuff well enough to make agood judgment.)
Large/complicated patches shouldstill go by one of our maintainers, or team consensus.
We are all reasonable people, and nobody is working underemployer pressure or needs an ego-boost badly, so in general weassume that no-one deliberately does anything stupid :-)

The directories involved are:

gcc/gcc/fortran/
gcc/gcc/testsuite/gfortran.dg/
