19. Migrations from old to new setups

This section is only to be used by people who have installed an LFS system using previous versions of this HOWTO. If a major change in an installation approach has taken place, you first need to take some actions such as removing existing files from a package before you can re-install that package. This section is used to assist people who obtained an old, obsolete version of this HOWTO and after installing the LFS system noticed that there's a new HOWTO (like this one) fixing things that went wrong in the older versions.

19.1 Migrating from old C++ Library setup to the new setup

This section only applies to people who have previously installed the C++ Library using LFS-HOWTO version 1.0, 1.1 or 1.2.

• Remove the following directory and symlinks: /usr/include/g++*

19.2 Migrating from old compiler setup to the new setup
