Subject: [PATCH] Document removal of macOS 32-bit support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
32-bit support has been deprecated for some time,
and several breaking changes have gone into the 5.10
branch.
Make the current state official: Qt 5.10 and higher
will not support 32-bit mode. Qt 5.9 LTS will continue
to do so.

See \l{Supported Platforms} for the list of \macos versions supported by Qt.
- Qt can be built for either x86 or x86_64. 64-bit is used by default.
- To select a 32-bit build, use the \c QMAKE_APPLE_DEVICE_ARCHS \c qmake variable.
+ Qt can be built for either x86_64 or x86_64h (Haswell). x86_64 is used by default.
+ To select a x86_64h build, use the \c QMAKE_APPLE_DEVICE_ARCHS \c qmake variable.
This is selectable at configure time:
\code
- ./configure -platform macx-clang QMAKE_APPLE_DEVICE_ARCHS=i386
+ ./configure -platform macx-clang QMAKE_APPLE_DEVICE_ARCHS=x86_64h
\endcode
\c QMAKE_APPLE_DEVICE_ARCHS can also be specified as a space-delimited list
in order to build for multiple architectures simultaneously:
\code
- ./configure -platform macx-clang QMAKE_APPLE_DEVICE_ARCHS="i386 x86_64 x86_64h"
+ ./configure -platform macx-clang QMAKE_APPLE_DEVICE_ARCHS="x86_64 x86_64h"
\endcode
+ \note Qt 5.10+ does not support 32-bit builds.
\note Qt 5 does not support OS X on PowerPC.
\note Static builds are not tested.
