5.14. Conflict Handling

There are three different variables to register a conflict between packages and ports: CONFLICTS, CONFLICTS_INSTALL and CONFLICTS_BUILD.

Note:

The conflict variables automatically set the variable IGNORE, which is more fully documented in Section 12.13, “Marking a Port Not Installable with BROKEN, FORBIDDEN, or IGNORE.

When removing one of several conflicting ports, it is advisable to retain the CONFLICTS entries in those other ports for a few months to cater for users who only update once in a while.

5.14.1. CONFLICTS_INSTALL

If your package cannot coexist with other packages (because of file conflicts, runtime incompatibilities, etc.), list the other package names in the CONFLICTS_INSTALL variable. You can use shell globs like * and ? here. Package names should be enumerated the same way they appear in /var/db/pkg. Please make sure that CONFLICTS_INSTALL does not match this port's package itself. Otherwise enforcing its installation with FORCE_PKG_REGISTER will no longer work. The CONFLICTS_INSTALL check is done after the build stage and prior to the install stage.

5.14.2. CONFLICTS_BUILD

If your port cannot be built if a certain port is already installed, list the other port names in the CONFLICTS_BUILD variable. You can use shell globs like * and ? here. Package names should be enumerated the same way they appear in /var/db/pkg. The CONFLICTS_BUILD check is done prior to the build stage. Build conflicts are not recorded in the resulting package.

5.14.3. CONFLICTS

If your port cannot be built if a certain port is already installed and the resulting package cannot coexist with the other package, list the other package name in the CONFLICTS variable. You can use shell globs like * and ? here. Packages names should be enumerated the same way they appear in /var/db/pkg. Please make sure that CONFLICTS_INSTALL does not match this port's package itself. Otherwise enforcing its installation with FORCE_PKG_REGISTER will no longer work. The CONFLICTS check is done prior to the build stage and prior to the install stage.
