1. Gcc Compiler For Mac Os X
2. Installing Gcc On Mac
3. Osx Gcc

If you'd like to use your Apple Mac with OS X for some numerical computation, this site could be useful to you. Most of these packages have been compiled/tested on several version of OS X and XCode Tools. Feel free to contact me with questions or problems!

The GNU Compiler Collection or GCC for short, comprises front ends for C, Objective-C, C, Java, Fortran, Go and Ada, along with libraries for the mentioned languages. GCC us the main component of the GNU toolchain, it is distributed under the GNU General Public License and plays a central role in the continuous growth of free software.

Computation Tools :: C/Fortran

GCC 4, 5, 7, 8, 9 (auto-vectorizing gcc with OpenMP):
Compiled using source code from the GNU servers. This contains current versions (8.3 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-9.2-bin.tar.gz (if your browser didn't do so already) and then sudo tar -xvf gcc-9.2-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 better 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 or higher, you can get the command-line tools by simply typing xcode-select --install. And on Catalina, you may have to specifify an additional include path -I/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include for the compiler to find the system headers.

g77 3.4 :
This is the FINAL release of g77 (version 3.4 compiler). Future versions of GCC will have gfortran (see above). Download my binaries, and cd to the download folder. Then gunzip g77-bin.tar.gz (if your browser didn't do so already) and sudo tar -xvf g77-bin.tar -C /. It installs everything in /usr/local. You will need to have Apple's Developer Tools installed. They are included on the retail DVD version of OS X and also available as a free download from Apple's Developer Site. Please install the most current version of Developer Tools. Thanks to James Wookey for the Intel Mac version of g77.
Binaries: g77-bin.tar.gz (PowerPC only), g77-intel-bin.tar.gz (Intel Mac only), updated October 2006.

Computation Tools :: Cactus, RNPL, etc.

Einstein Toolkit:
The Einstein Toolkit is an open-source software framework specifically targeted to the research area of numerical relativity and astrophysics. The broad aim of the toolkit is to provide the core computational tools that enable scientific research in this area, and take advantage of emerging petascale computers and advanced cyberinfrastructure.The Einstein Toolkit compiles and runs great on Mac OS X. A critical component of this toolkit is the Cactus Computing Toolkit (see below).

CactusCode (Numerical Computing Toolkit):
Cactus is an open source problem solving environment designed forscientists and engineers. Its modular structure ('thorns') easilyenables parallel computation across different architectures andcollaborative code development between different groups. It ismainly used for solving complicated PDE's. It highly portable, andhas some really remarkable features like observing and even'controlling' or 'steering' a running simulation using an ordinaryweb browser! Here is a link to a perpetual demo running at LSU Cactus Demo. Check it out!Cactus compiles and runs great on Mac OS X.

RNPL (Rapid Numerical Prototyping Language):
This is a great tool that takes as input details about the form ofan equation (usually a partial differential equation), and someparameters . and then spits out a C or FORTRAN Code that solvesthe equation numerically using established iterative numericaltechniques. RNPL can also be used for producing skeleton programsand for converting existing programs. Download the source, compileand install. This source has been modified to compile with OS X. Orget my binary distribution. You probably want to install this in/usr/local, to do so gunzip rnpl-bin.tar.gz (if your browser didn't do so already) and then sudo tar -xvf rnpl-bin.tar -C / and you are done! You will need to use the F77 flag: -fno-second-underscore, for RNPL generated F77 codes to compile properly.
Source: rnpl.tar.gz
Binaries: rnpl-bin.tar.gz, updated 2003.

Gcc Compiler For Mac Os X

The GRAVSIM Package:
GRAVSIM is a package that contains an ever evolving and hopefully growing set of gravitational N body solvers. These solvers attempt to track the motion of a set of bodies moving under the influence of gravity. They are used in many areas of astrophysical study including planetary motion, star cluster formation and stability and galactic formation, stability and interactions (i.e. colliding galaxies). This package is highly AltiVec and DP optimized!

Xmgr Grace:
This is a very easy to use, open-source, X11 based, plotting tool. I used it during my graduate school days and still love it. Its excellent especially for students and free! Note: I didnot create this binary, but I have tested it on both Intel and PPC Macs. It works very well. Move the Grace application to the system /Applications folder for it to function correctly.By the way, if you are looking for a nice, easy to use, 2D and 3D,plotting package for OS X, try pro Fit. It works great. They have a free trial version, that is not time-limited and is full-featured. It just has some restrictions on the volume of data you can make it handle. Even the full version is very inexpensive.

The Mac OS X operating system is a variant of unix (called Darwin, which is a derivative of BSD unix). It is a versatile computing platform suitable both for computational chemistry calculations and for developing and compiling programs.

Although scientific programs use a variety of languages (basic, pascal, c, java, perl, python, ..), a substantial base of scientific code is written in fortran. Most (though not all) computational engines supported by WebMO are written in fortran. This resource concentrates on fortran compilers and the tools needed to support them.

While integrated development environments (IDE's) are useful in supporting program development, this resource concentrates on the command line interface (CLI) using the Terminal application that is supplied with OS X. Sony content browser for mac sierra.

The procedures discussed on this page have been designed for Mac OS X 10.5.

SOFTWARE DEVELOPMENT UTILITIES AND c COMPILER

Command line program development often uses unix utilities (cvs, make, ranlib, ..) when developing and compiling a project. These utilities, together with the c compiler for OS X, are available as part of the Xcode Tools that come with OS X. However, they are not installed by default.

1. Insert Mac OS X Installation DVD. Navigate to the Optional Installs: Xcode Tools folder.
   
2. Double-click XcodeTools.mpkg. Follow the prompts, but at Installation Type, click the Customize button.
   
3. Uncheck all the components and check only Unix Development Support. In particular, Developer Tools Essentials should be unchecked (saving you 2.5GB of disk space)!
4. Provide your password for the installation will proceed.
5. Notes:
   
   • The latest version of Xcode Tools can be obtained by registering for a free ADC membership and then downloading the latest version of Xcode from Apple (caution: it is > 1GB!).
     
   • Xcode can be uninstalled by running
     as described in the Xcode Tools Uninstaller

g77 COMPILER

g77 is the gnu fortran77 compiler. It was last produced with gnu compiler collection (gcc) 3.4, and has since been supplanted with gfortran which supports fortran95. Because of the free-cost and high quality of the gnu copmpilers, a significant amount of software has been developed for and compiled with the g77 compiler.

A tar file of the final realease of g77 compiled for OS X exists at High Performance Computing for Mac OS X.

1. Download g77-intel-bin.tar.gz (Intel Mac only) or g77-bin.tar.gz (PowerPC only)
   
2. If your browser did not automatically unzip the file, then
   
   $ gunzip g77-bin-intel.tar.gz
   
3. Install the distribution
   which puts everything in /usr/local
   
4. Notes:
   
   • No uninstall script exists, so the install files need to be listed from the tar file and manually deleted. The following command automates the process of deleting all installed files and empty directories:
     
     $ tar -tf g77-bin.tar sort -r (cd /; xargs -p -n 1 rm -d)
     
     You may wish to replace the '-p' switch with '-t' so that you are not prompted to delete each file.
     
   • G77 documentation is available at GCC Online Documentation
     

gfortran COMPILER

gfortran is the new gnu fortran compiler, which attempts to follow the fortran95 standard. As such, it should be backward compatible with fortran77 and fortran90. It also promises to attempt following future fortran standards, such as fortran2003. gfortran replaces the gnu g77 compiler and is included with gnu compiler collection (gcc) 4.0 and higher.

Although Apple XCode Tools includes gcc 4.X, it is not a complete implementation and lacks gfortran. However, various implementations of gfortran have been compiled and are available at GCC Wiki GFortranBinaries, Tools - R (and Fortran) for Mac OS X, or High Performance Computing for Mac OS X. These implementations vary by version, platform supported, and integration with XCode Tools. Important: Install only one implementation of gfortran, as each version would overwrite portions of the others!

• The 'GCC Wiki' implementation described in the following procedure is typically the newest binary release of gfortran, but requires that you download a version appropriate for your architecture.
  1. Visit the GCC Wiki GFortranBinaries page and scroll to the MacOS section
  2. Download gfortran-macosx-x86.dmg (Intel) or gfortran-macosx-ppc.dmg (PowerPC)
     
  3. If your browser did not automatically mount the disk image, the double-click the dmg file to mount and open it
     
  4. Open the gfortran-macosx-{architecture}-{version} folder, double-click gfortran.pkg, and follow the prompts to install it
  5. Notes:
     
     • All gfortran files are installed in /usr/local/gfortran, and a single symbloic link /usr/local/bin/gfortran is created. Thus, to uninstall the package, run
       
       $ sudo rm -r /usr/local/gfortran /usr/local/bin/gfortran
       
     • GNU Fortran documentation is available at GCC Online Documentation
       
• The 'sourceforge' implementation described in the following procedure requires that you download a version appropriate for your architecture, does not produce 'fat binaries', and does not come with an uninstall script (although a method is provided below)
  1. Download gfortran-leopard-intel-bin.tar.gz (Intel) or gfortran-leopard-ppc-bin.tar.gz (Power PC)
     
  2. If your browser did not automatically unzip the file, then
     
  3. Install the distribution
     
     $ sudo tar -xvf gcc-leopard-intel-bin.tar -C /
     
     which puts everything in /usr/local
  4. Notes:
     
     • No uninstall script exists, but the following command will delete all installed files and empty directories:
       
       $ tar -tf gfortran-leopard-intel-bin.tar sort -r (cd /; xargs -p -n 1 rm -d)
       
       You may wish to replace the '-p' switch with '-t' so that you are not prompted to delete each file.
       
     • GNU Fortran documentation is available at GCC Online Documentation
       
• Note that there is a G95 project, which is completely independent of the gnu gfortran project (despite the similarity with the gnu g77 compiler name). The G95 project is not associated with the gnu compiler collection!

f2c TRANSLATOR / f77 COMPILER f2c is a fortran77-to-c source code translator. Because f2c is written in c and its ouput is c, both of which can be compiled natively on unix operating systems, f2c offers a very transportable compiler solution for compiling fortran programs. f2c also offers a means of converting large fortran libraries, such as LAPACK, into c. f2c is still actively maintained and is available at http://www.netlib.org/f2c/.

For newer Macs, use a USB 3.0 drive—it makes things significantly faster. Make boot disk for windows 10. A Mac that you have administrator access to, duh. We've created Sierra USB stick from both El Capitan and Sierra, but your experience with other versions may vary. An 8GB or larger USB flash drive or an 8GB or larger partition on some other kind of external drive.

f77 was the first complete fortran77 compiler and was written in c. The original f77 program is no longer available for current computer architectures. However, f2c is based on the original f77 program, and the f2c distribution contains a f77 wrapper script that combines the f2c translation and c compilation steps. The f77 script also supports many command line options commonly associated with fortran compilers. Since the f77 script calls f2c, which in turn is based upon the original f77 program, the f77 script within the f2c distribution represents the most current implementation of the original f77 program.

1. Download the installation script install_f2c_osx.csh which is
2. Run installation script
   
   $ chmod +x install_f2c_osx.csh
   $ sudo ./install_f2c_osx.csh
   
   which will produce the following files:
   /usr/local/bin/f2c
   /usr/local/include/f2c.h
   /usr/local/lib/libf2c.a
   /usr/local/man/man1/f2c.1t
   /usr/local/bin/f77
   
3. Translate, compile, link, and run a program
   
   $ f2c hello.f
   $ gcc -c hello.c
   $ gcc -o hello hello.o -lf2c -lm
   $ ./hello
   
   Or combine the first three steps into a single command
   
4. To uninstall f2c, manually delete the five files produced above
