This page describes changes to the 4.2.1 build system.
Fix an issue where the wrong RPATH is used for SDK binaries.
Search <build>/lib before directories specified with -L.
Some files were missing from the SDK.
Image installation logic was refactored. See installpic for the logic. A new switch was added to let you specify your preference for image files (where multiple types of the same file exist).
.desktop files were erroneously installed to the image.
pkg.no_install lets you exclude targets from the default package.
configure -force-quicklaunch forces quicklaunch-capable apps to be built with quicklauncher (ignoring no_quicklaunch).
