@ -44,3 +44,15 @@ Now, your br2-external tree can be used with Buildroot 2016.11 onward.
.Note:
This change makes your br2-external tree incompatible with Buildroot
before 2016.11.
[[migrating-host-usr]]
=== Migrating to 2017.08
Before Buildroot 2017.08, host packages were installed in +$(HOST_DIR)/usr+
(with e.g. the autotools' +--prefix=$(HOST_DIR)/usr+). With Buildroot
2017.08, they are now installed directly in +$(HOST_DIR)+.
Whenever a package installs an executable that is linked with a library
in +$(HOST_DIR)/lib+, it must have an RPATH pointing to that directory.
An RPATH pointing to +$(HOST_DIR)/usr/lib+ is no longer accepted.
