From 6c222297ab19e1bc6b74c4290446c1cb61f6fda8 Mon Sep 17 00:00:00 2001 From: Martin Afanasjew Date: Mon, 19 Oct 2015 23:52:10 +0200 Subject: Make -no-rpath build more useful on Apple platforms [ChangeLog][Platform Specific Changes][OS X] Configure with -no-rpath will now yield Qt dynamic libraries and frameworks with an absolute install name (based in -libdir). OS X package managers like Homebrew install Qt in a fixed location. This change simplifies deployment for such package managers and is consistent with the default expectation on Apple platforms for libraries with a fixed location to also have absolute install names. While a relocatable installation (the default) also works in this scenario, it requires all software that depends on Qt to be aware of this and to embed a suitable RPATH into application binaries (which is not automatic for non-qmake builds). This might not be true for some select fallback search locations, but as package managers on OS X tend not to use those, embedding an RPATH becomes practically mandatory. In a default Homebrew installation, Qt is configured such that the frameworks end up in /usr/local/Cellar/qt5//lib and that will be later symlinked to /usr/local/opt/qt5/lib, both of which are not searched by the dynamic linker by default.
