Gfortran For Mac Catalina

13.01.2021 admin

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 For Mac Catalina Installer

I am having a problem with command tools, i am using mac 10.8, downloaded the command tool, install it.The installation goes step by step as described. But when installation finish, it treats the software as an external drive, or doesn’t install it in “machintosh HD” as it is supposed to. This is a pseudo Fortran77 compiler for Atmel AVR microcontroller, written in Fortran using gfortran compiler. The compiler use avr-gcc-4.9.2 as dependency. The recent version of compiler is 1.0.1-alpha. MacBook Pro, Mac OS X (10.7.4) Posted on Jun 6, 2012 5:14 AM Reply I have this question too ( 4 ) I have this question too Me too (4) Me too. Gfortran for Mac. DISCLAIMER: I provide this information here to aid my memory and in the hope that others will find it a useful resource based on my experiences of installing a gfortran compiler on Macs. The first x86-64 binary was built on 10.7 (Lion) using gfortran v4.2 and should run on 10.7 and later OS X versions. The second binary was built on 10.15 (Catalina) with gfortran 8.2. It seems to run on older OS X versions at least back to 10.11 (El Capitan).

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.)

Install Gfortran On Mac

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 :-)

Usage

Here is a shortexplanationon how to invoke and use the compiler once you have built it (ordownloaded the binary).

Question or issue on macOS:

I have recently become frustrated with the new clang compiler included with Xcode 5. I was wondering what the best way to install GNU GCC on OS X would be.

Things to consider:

EDIT: Success! Using GCC 4.9.2 (with GMP 5.1.3, MPFR 3.1.2, MPC 1.0.2, ISL 0.12.2, and CLooG 0.18.1) I succesfully built GCC. Tips to take from here:

Hope this helps!

How to solve this problem?

Solution no. 1:

The way I do it is:

Download the source for GCC and numerous supporting packages. The instructions are in the gcc-4.x.y/INSTALL/index.html file in the GCC source code, or online at http://gcc.gnu.org/install/.
- GNU Multiple Precision Library (GMP) version 4.3.2 (or later) from http://gmplib.org/.
- MPFR Library version 2.4.2 (or later) from http://www.mpfr.org/.
- MPC Library version 0.8.1 (or later) from http://www.multiprecision.org/.
- ISL Library version 0.11.1 from ftp://gcc.gnu.org/pub/gcc/infrastructure/.
- CLooG 0.18.0 from ftp://gcc.gnu.org/pub/gcc/infrastructure/.
Use a script to extract the source for GCC and the support libraries into a directory, create the object directory, and run the build.

This is the script I used for GCC 4.8.2: /hiro-wireless-usb-adapter-drivers.html.

When that finishes, run the install too. Then add $HOME/gcc/gcc-4.8.2/bin (the name you specify in --prefix plus /bin) to your PATH ahead of /usr/bin.

With a decent MacBook Pro with a 5400 rpm spinning disk, it takes an hour or two to compile everything (using the -j8 option to make), and requires multiple gigabytes of disk space while compiling. SSD is nice when doing this (definitely faster)!

GCC 4.9.0 was released on 2014-04-22. I've installed it using basically the same process, but with CLooG 0.18.1 and ISL 0.12.2 (required updates) and GMP 5.1.3 (and 6.0.0a), MPC 1.0.2 (or 1.0.1) and MPFR 3.1.2 on Mac OS X 10.9.2 Mavericks and an Ubuntu 12.04 derivative. Beware that the gmp-6.0.0a.tar.xz extracts into directory gmp-6.0.0 (not gmp-6.0.0a as you might expect).

Between 2014 and 2017-09-27, I've built GCC versions 4.9.0, 4.9.1, 5.1.0, 5.2.0, 5.3.0, 6.1.0, 6.2.0, 6.3.0, 7.1.0 with only minor variations in the build script shown below for GCC 7.2.0 on macOS Sierra (10.12). The versions of the auxilliary libraries changed reasonably often.

macOS Sierra and High Sierra

On 2017-08-14, I used a minor variant of the script above to build GCC 7.2.0 on macOS Sierra 10.12 (using XCode 8 as the bootstrap compiler). One change is that CLooG doesn't seem to be needed any more (I stopped adding it with GCC 6.2.0). This is my current script:

Make sure your version of tar supports all 4 different compressed file formats (.lz, .gz, .xz, .bz2), but since the standard Mac version of tar does that for me, it'll probably work for you too.

On 2017-09-27, I failed to build GCC 7.2.0 on macOS High Sierra 10.13 (using XCode 9 for the bootstrap compiler) using the same script as worked on Sierra 10.12. The immediate error was a missing header <stack>; I'll need to track down whether my XCode 9 installation is correct — or, more accurately, why it isn't correct since <stack> is a standard header in C++98 onwards. There's probably an easy fix; I just haven't spent the time chasing it yet. (Yes, I've run xcode-select --install multiple times; the fact that I had to run it multiple times because of network glitches may be part of the trouble.) (I got GCC 7.2.0 to compile successfully on 2017-12-02; I don't recall what gymnastics — if any — were required to get this to work.)

Time passes; version numbers increase. However, the basic recipe has worked for me with more recent versions of GCC. I have 7.3.0 (installed 2018-01-2), 8.1.0 (installed 2018-05-02), 8.2.0 (installed 2018-07-26), 8.3.0 (installed 2019-03-01) and now 9.1.0 (installed today, 2019-05-03). Each of these versions was built and installed on the current version of macOS at the time, using the current version of XCode for the bootstrap phase (so using macOS 10.14.4 Mojave and XCode 10.2.1 when building GCC 9.1.0)

Solution no. 2:

Homebrew now has the GCC package so you can install it with this command:

Solution no. 3:

Use a pre-compiled binary specifically for OS X 10.9.x Mavericks:

→ gcc-4.9

Compiled using source code from the GNU servers.

This contains current versions (4.7 is the stable release) of gfortran
(free, open source, GNU Fortran 95 compiler), gcc (GNU C) and g++ (GNU
C++) compilers that can perform auto-vectorization (i.e. modify code
to take advantage of AltiVec/SSE, automatically) and other
sophisticated optimizations like OpenMP. For more information, see
this webpage.
Download my binaries, and cd to the download folder. Then gunzip
gcc-4.9-bin.tar.gz (if your browser didn't do so already) and then
sudo tar -xvf gcc-4.9-bin.tar -C /. It installs everything in
/usr/local. You can invoke the Fortran 95 compiler by simply typing
gfortran. You will also need to have Apple's XCode Tools installed
from the Mac App Store. With XCode 4 or 5 you will need to download
the command-line tools as an additional step. You will find the option
to download the command-line tools in XCode's Preferences.
On 10.9 Mavericks, you can get the command-line tools by simply typing
xcode-select --install.
