- 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. I am not a computer scientist or Fortran guru and, as such, am unlikely to be able to help you with Fortran code, compilation or runtime.
- New Features. JGRASP version 2.0.605 Beta adds CSD, interactions, and run support for Java 15 features (text blocks). JGRASP version 2.0.6 includes dark themes.

Compiler
This document will help you install and configure a C++ compiler. Choose yourplatform and install. You can test by opening Terminal (Mac) / cmd.exe(Windows) and entering
g++
. If you get a warning that no files wereprovided, then you're all set! Otherwise, if you get an error about the commandnot being found, then the C++ compiler is not installed properly.Mac
OSX 10.9 and later
Open the Terminal application: hit Command+Space and type 'terminal';select 'Terminal' from the drop down. In the terminal window that pops up, type
g++
. If you do not have the necessary compiler files installed, youwill be prompted to install Mac's Command Line Tools. Install those and youshould be all set.OSX 10.8 Mountain Lion or earlier
First, make sure that your security settings allow for software to be installedfrom anywhere. To do this, go open your System Preferences (go to the apple inthe upper left and select 'System Preferences'). Then select 'Security &Privacy'. If the lock icon is closed in the bottom left of the window, click itto unlock your settings. Then click the option to allow apps downloaded from'Anywhere'. After you follow the next steps, feel free to go back and changeyour settings back to what they were.
This project is for you as it will get you only the parts ofXCode that you need for this. Download and install the package that matchesyour version of OSX (10.6 'Snow Leopard', 10.7 'Lion', 10.8 'MountainLion').
Now open a terminal: press Command+Space top open Spotlight and type'terminal'; select 'Terminal' from the drop down. In the terminal window thatpops up, type
g++
. If the compiler installed correctly, you shouldsee an error that looks something like:If you see something like this, you're all set.

a. Download and install MinGW
DownloadMinGW and install it. The first window in the installation process shouldlook like this:
Select 'Install'. The next screen will ask you for some options. Just stick withthe defaults and click 'Continue'.
That will cause MinGW to be downloaded. You should see a window like below; onceit's finished, select 'Continue'.
b. Install libraries
In the MinGW Installation Manager, we need to mark a set of packages to install.
Start by right clicking on the 'mingw32-base' package and select 'Mark forInstallation', as shown in the screen shot below. That will make the little boxto the left turn green with a little arrow on it.There's a few more packages you need to mark—be sure that you right-clickon the following four packages and select 'Mark for Installation'. This willcause many additional packages to be marked automatically (don't worry, that'ssuppose to happen):
- Under 'Basic Setup':
- mingw-developer-toolkit
- mingw32-base
- mingw32-gcc-g++
- msys-base
- Under 'All Packages' (to get to this, click on 'All Packages' in the far-left pane, then scroll down in the pane on the right until you see the package name):
- mingw32-libpdcurses (mark the dev package, and the dll package will automatically be marked)
Once you've marked all these, you'll need to apply the changes. Do this byclicking the 'Installation' menu and selecting 'Apply Changes', like this:
That will cause a confirmation window to appear; click 'Apply':
That downloads and installs all the packages marked for installation. Once it'sfinished, the installation window will stay open; just click 'Close':
And finally, you can close out of the MinGW Installation Manager. The next thinkyou'll have to do is set your path (see the section below).
c. Set environment variables
In order to use the compiler, you need to update your computer's Pathenvironment variable to include the location of MinGW ad MSYS as follows:

- Get to your computer properties:
- Windows 7: Right click on 'My Computer' and select properties:
- Windows 8: Go to start (hit windows key) and start typing 'advanced'; this should issue a system search and one of the results should be 'View advanced system settings'—click that:
- Windows 10: Hit the windows key and type 'system environment'; this will bring up the search result 'Edit the system environment variables'—click that
- Windows 7: Right click on 'My Computer' and select properties:
- Click on 'Advanced Settings' and from the 'Advanced' tab click the
Environment Variables
button: - In that popup window you want to edit the Path system variable by first finding it under the 'System variables' section (1 in the following image) and then selecting 'Edit' underneath (2 in the following image).
- In Windows 7 and 8, you should add the following at the beginning of the value already present:
C:MinGWbin;C:MinGWmsys1.0bin;
(make sure to include the trailing semicolon). Do not remove the text that is already there, as that may cause other applications to fail. - In Windows 10, click 'Edit' (1 in the following image) then type in the first path:
C:MinGWbin
(2 in the following image). Repeat that for the second path:C:MinGWmsys1.0bin;
; press 'OK' when both variables have been entered.
- In Windows 7 and 8, you should add the following at the beginning of the value already present:
- Next, we need to create a variable called HOME; under 'Users variables for <your user name>', click the 'New...' button
- In the 'Variable name' text field, enter 'HOME', and in the 'Variable value' text file, enter '%USERPROFILE%':
- Click 'OK'
- You're all done setting variables, so click 'OK' to exit the editor
Now open a the system command prompt by pressing Win + r (Windows key and 'r' key) and type 'cmd' in the box that pops up. Click 'OK'. Here's what it shouldlook like:
A black windows shouldpop up with a command prompt. Type
g++
;if you get a warning that no files were supplied, you're all set. Here's whatsuccess looks like:If youget an error that the command g++ was not found, then something went wrong—most likely, the Path variable was not set properly. Here'swhat that looks like:
