qt5: factor out common definitions and remove symlink farm The module definitions are factored out and shared between qt56 and qt59. The symlink farm which was created during builds is no longer needed. 2017-10-24 13:39:54 +02:00			`{ stdenv, lib }:`

qt5: reduce closure size First, closure size is reduced by including the static libraries in $out instead of trying to move them to $dev. The Qt build system cannot handle libraries being split between different prefixes. Previously, the static libraries were moved into $dev and the shared libraries were symlinked from $out to $dev to fool the build system. However, this causes $dev to be retained at runtime. Instead, we now keep the static libraries in $out. Fortunately, the static libraries are not very large anyway. Second, we build with QT_NO_DEBUG defined unless debugging is enabled. This causes some assertions to be removed; when assertions are included, they pull paths from $dev into the runtime closure by using the __FILE__ macro. We also now patch qtbase to remove even more assertions when QT_NO_DEBUG is defined. 2018-01-02 14:16:38 +01:00			`NIX_CFLAGS_COMPILE = optional (debug != null) "-DQT_NO_DEBUG";`
