Installing eclipse ide in windows 11 for c,c++ and/or fortran

I want to look back at some fortran code I wrote back in the 80s, so having used gnu/eclipse long ago, I'd like to set it up again.

I've installed the eclipse ide

Eclipse IDE for C/C++ Developers (includes Incubating components)

Version: 2025-12 (4.38.0)

Build id: 20251204-0850

On search there is a download https://www.eclipse.org/downloads/packages/release/photon/r

and see the scientific computing download.

Do I download both the eclipse ide and the scientific plugin and somehow connect the two?

I have downloaded both and if I run the eclipse ide c/c++ it starts up fine. If I run the eclipse ide from the scientific computing download I get a java rte (jre, jdk) issue. Do you somehow plugin the scientific ver. to regular eclipse ide. Looking at the two eclipse.ini files there are some differences so to be honest I don't know if I need to install the c/c++ ide then overwrite with the scientific one or what I need to do to get it to work.

Solution

  • The "Eclipse IDE for Scientific Computing" package has been discontinued so you should probably not use that any more. The link you shared is from Eclipse Photon which was released in 2018 and is fairly old.

    If you look at the "Detailed feature list" of that Eclipse package, you can see the included features which notably includes org.eclipse.ptp.fortran. Furthermore, the Fortran Development tools had their last release in 2015 and the GitHub repository is archived.

    Installing Fortran Development tools into recent Eclipse versions

    However, you can still try to install the Fortran tooling in recent Eclipse versions. To do that, you can add https://download.eclipse.org/tools/ptp/releases/9.4/ptp-9.4.1/ as an update site in your Eclipse (for C/C++ Development) installation and install "Fortran Development Tools":

    adding an update site PTP update site with Fortran Development tools installed

    Install the most recent version of Eclipse IDE for scientific computing

    If I run the eclipse ide from the scientific computing download I get a java rte (jre, jdk) issue.

    The release you tried to install is pretty old so it might not work with the JDK you are using. To fix this, you can try to install a more recent release, for example, 2023-06.
