Development Environment / Eclipse and Photran

Eclipse is not actively used by the main StateCU developers. It was initially evaluated as an option. The Eclipse and Photran versions described in this documentation will need to be updated.

Eclipse is used for the integrated development environment (IDE). The Eclipse Photran plugin is used to provide a Fortran IDE, which can facilitate editing code, debugging, etc. The following Eclipse/Photran download page indicates that Eclipse Mars is required.

This documentation includes the following sections:

Prerequisites

The prerequisites for installing Eclipse are:

  • Java 8 - Java is needed to run Eclipse
  • gfortran compiler - Eclipse relies on gfortran and other development tools having been installed in MinGW, Cygwin, or Linux

Install Eclipse and Photran

The Photran installation instructions recommend installing Eclipse for Parallel Application Developers, which will install support for C, Fortran, and other tools. Although there is currently not a need to develop StateCU for parallel processing, this may be a need for StateMod in the future so this environment may have benefits. It is also typically easier to pick a standard Eclipse installer rather than having to piecemeal plug-in installation. Use the following link:

This will default to the newest environment, which is Neon. Based on the Photran documentation, use the older Mars version. Therefore, use the links on the right side of the download page to access Eclipse Mars downloads:

Then click on the Download link to see:

Select the Eclipse for Parallel Application Developers link for the appropriate operating system.

Linux

This documentation will be completed when resources are available for Linux development and testing.

Windows

The Windows installer will have a filename similar to eclipse-parallel-mars-2-win32-x86_64.zip and will save to the Downloads folder.

Eclipse is distributed as a zip file. Therefore, a program like 7zip is needed to install.

The top-level folder in the zip file will be eclipse. Because it is possible to install multiple versions of Eclipse (for example the Java package will be used to develop Java software), it is recommended that the install location have a name specific to the version. For example, unzip to C:\Program Files\Eclipse\eclipse-parallel-mars-64, renaming the top folder. It may be easier to unzip in the Downloads folder, rename, and then copy into the C:\Program Files\Eclipse folder. The resulting folder structure will be similar to:

C:\Program Files\
     Eclipse\
         eclipse-parallel-mars-64\
             eclipse.exe
             eclipse.ini
             etc.

It is possible to create a desktop shortcut to Eclipse. However, before doing so, it is recommended to create a batch file to run eclipse, as per the Initial Project Setup / Eclipse Run Script. The batch file is the recommended way to start Eclipse for StateCU development; however, the desktop shortcut is a convenience for general Eclipse use.

The above script can be double-clicked on or run from a Windows Command Shell. If necessary, the default script can be copied and modified for a specific developer.

To create a shortcut, use Windows File Explorer and right-click on the C:\Program Files\Eclipse\eclipse-parallel-mars-64\eclipse.exe file and select Create shortcut. On Windows 10, the following warning may be shown:

Eclipse shortcut warning

Press Yes. A shortcut labeled eclipse.exe Shortcut will be shown on the desktop. Right-click on the icon and select Properties. Then change the properties as follows, consistent with the Eclipse run script:

  • Change the name to something like Eclipse Parallel Mars 64.
  • Change the Shortcut tab Target to be similar to the batch file above: "C:\Program Files\Eclipse\eclipse-parallel-mars-64\eclipse" -vm "C:\Program Files\Java\jre8\bin\java" -vmargs -Xmx700M

Double-clicking on the shortcut desktop icon should then run the desired Eclipse.

Next Steps

Additional Eclipse configuration will be performed after finishing development environment setup, as per the Initial Project Setup documentation - do not do now.
