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.

Before running the app, you first have to install the GnuCOBOL compiler, e.g. using homebrew:

brew install gnu-cobol

If you installed the compiler in a non-standard path and it is not recognized by the IDE, you can specify the path to the compiler in the preferences dialog (Compiler tab)
