Example: mysql and perl-DBD depend on each other. To avoid problems that can occur with circular dependencies, it is best to install both packages at the same time. The following example describes how to handle circular dependencies in Linux Package Editor. Linux Package Editor Reference 33 Creating Linux Packages Example: You import an RPM for Application A into Linux Package Editor. The Dependencies page shows a dependency on Application B. During testing, you try to install Application B before you run the Application A installation. The Application B installation fails because it requires Application A. To resolve this circular dependency, do the following in the Application A package: 1. On the Files page, add the Application B package file to $WISEFOLDER. On the Build Settings page, enter the following in the RPM Command Line Options field: $WISEFOLDER\application B file name This must precede any other options in the command line. Note If the dependency files are removed from this package, remove this line from the command line. At run time, the Application B file is extracted from $WISEFOLDER before the Pre-RPM script runs. This makes it available to the rpm command so that it can be installed at the same time as the Application A files.
