From cc1a28d07e0771300403c06a00742b8648d3f70d Mon Sep 17 00:00:00 2001 From: James McDonnell Date: Fri, 18 Mar 2016 11:32:13 -0400 Subject: Add the ability to change precompiled header use Give the Windows configureapp the same -pch/-no-pch arguments found in the Linux configure script. Using command line arguments to enable/disable precompiled header use is preferable to mkspec changes. Make -pch the default for all toolchains. In particular, this makes -pch the default for QNX on Windows. Previously, QNX on Windows had an implied default of -no-pch. Precompiled headers are the default for QNX on Linux; they should also be the default for QNX on Windows. A 'dictionary["PCH"] = "no"' will need to be added in Configure::applySpecSpecifics for any toolchain that should default to -no-pch (none known at this time). -no-pch is implemented by putting a "CONFIG -= precompile_header" in qmodule.pri. This ensures that Qt is built without precompiled headers (as requested) even if allowing precompiled header use is the default for the toolchain.
