OpenCobolIDE is available from the AUR.

You can install using one of the many available AUR helper; e.g. using yaourt:

yaourt -S opencobolide


OpenCobolIDE is up in the KaOs Community Package (KCP):

Other distributions

Install Python3, PyQt5, GnuCOBOL and pip for Python3 using your package manager, then run the following commands:

sudo pip3 install OpenCobolIDE --upgrade

Note that if you have both PyQt5 and PyQt4 on your system, the IDE will use PyQt5 by default. To force the use of PyQt4, you should set the QT_API environment variable to pyqt4.

The only thing you have to do is:

  • to install GnuCOBOL compiler, e.g. using homebrew:

    brew install gnu-cobol
  • run the OpenCobolIDE app


If you installed the compiler in a non-standard path and it is not recognized, you can specify and the path to the compiler in the preferences dialog under the Build & Run section. Just make sure to only specify the directory where the compiler can be found, not the full path.
