When submitting applications to the iOS and macOS AppStore the
application goes through static analysis, which will trigger on
uses of various privacy protected APIs, unless the application
has a corresponding usage description for the permission in the
Info.plist file. This applies even if the application never
requests the given permission, but just links to a Qt library
that has the offending symbols or library dependencies.
To ensure that the application does not have to add usage
descriptions to their Info.plist for permissions they never
plan to use we split up the various permission implementations
into small static libraries that register with the Qt plugin
mechanism as permission backends. We can then inspect the
application's Info.plist at configure time and only add the
relevant static permission libraries.
Furthermore, since some permissions can be checked without any
usage description, we allow the implementation to be split up
into two separate translation units. By putting the request in
its own translation unit we can selectively include it during
linking by telling the linker to look for a special symbol.
This is useful for libraries such as Qt Multimedia who would
like to check the current permission status, but without
needing to request any permission of its own.

Sanitizing the contents of the QTPLUGIN variable, and adding default
plugins from the available modules, should be a separate step before
the resulting QTPLUGIN is iterated and processed by for example linking
to each plugin, generating an import file, and adding module dependencies.
This makes it easier to add logic to the processing step later on.

The -mno-direct-extern-access tells the compiler and linker that
references to symbols outside this ELF module mustn't be direct and must
instead always go through the GOT or PLT (the PLT can additionally be
disabled with -fno-plt). The ELF protected visibility tells the compiler
and linker that this symbol is present in the dynamic symbol table as an
export, but it cannot be interposed by another ELF module.
This option is required for user code to link properly to Qt, otherwise
they will get linker errors (assuming GNU binutils >= 2.39) or runtime
failures (glibc >= 2.35). Both versions of glibc and binutils are older
than GCC 12, so it's a safe assumption they are in use and downgrading
the toolchain or libc is not supported. Adding this option to the
compilation is assured for CMake and qmake-based projects.
For example, all accessess to QCoreApplication::self in QtCore, after
this change and with GCC 12 are relocation-free and direct:
000000000013ebf0 <QCoreApplicationPrivate::checkInstance(char const*)>:
13ebf0: cmpq $0x0,0x4f73d0(%rip) # 635fc8 <QCoreApplication::self>
13ebf8: setne %al
13ebfb: je a90fe <QCoreApplicationPrivate::checkInstance(char const*) [clone .cold]>
13ec01: ret
Meanwhile, accesses to the same variable in other modules are indirect
via the GOT:
66650: mov 0x876e1(%rip),%rax # edd38 <QCoreApplication::self@Qt_6>
66657: cmpq $0x0,(%rax)
This replaces the -Bsymbolic and -Bsymbolic-functions (broken)
functionality that Qt has been using or attempting to use since ~2006.

Consider a release-only, non-framework Qt build on macOS. Building a

Building a debug user project that uses QtUiTools against a release-only

Fix this by maintaining a list of library file candidates, and use the

the library matching the user project's configuration but falls back to

possible that the "testdata" resource that is generated in testcase.prf was

file though. It's a "qmake struct" that contains files and a base folder
so that we should add every file from the "file list" of that struct.
It is possible, that the generated resource has a base, but no files. Thus
we need two loops or we can end up with a command line that ends with

When Qt is configured for both debug and release, and frameworks are
enabled, we produce two dynamic libraries inside each framework, eg:
QtCore.framework/QtCore
QtCore.framework/QtCore_debug
When building an executable against these frameworks, we pass -framework
QtCore, and the resulting executable will have its LC_LOAD_DYLIB load
commands pointing to e.g.:
@rpath/QtCore.framework/Versions/5/QtCore
When running the executable, the dynamic loader will load the dynamic
library dependencies based on these load commands.
By setting the DYLD_IMAGE_SUFFIX environment variable at runtime to
'_debug', the dynamic loader will prefer the debug versions of each
library inside the frameworks.
Unfortunately the use of an environment variable to choose debug or
release versions leaves room for mismatches between the executable
and the libraries that are loaded. An executable built in debug
mode will at runtime pick up the release versions of the Qt libraries
unless the DYLD_IMAGE_SUFFIX has also been set to match the build
configuration of the executable.
This results in confusing situations such as building your application
in debug mode, and then stepping into Qt code but not getting any
symbols. Qt Creator has an option to run the application with
DYLD_IMAGE_SUFFIX set, but this is not enabled by default due
to the startup cost of loading the Qt debug libraries.
More critically, it results in tests failing when the tests are using
QTest::ignoreMessage to ignore warnings produced by Qt, and these
calls are ifdefed (correctly) inside QT_NO_DEBUG, as the test
(built in debug mode) will then expect warnings from Qt, but those
warnings are not emittet, as the test is run against the release
version of the Qt libraries.
To mitigate this mismatch, we now link the Qt frameworks using
an explicit suffix, just like we would for no-framework builds
on macOS, for debug and release builds on Windows, and for
normal builds on other Unixes, leaving the dependency chain
for the application predictable:
@rpath/QtCore.framework/Versions/5/QtCore_debug
This also conceptually matches how Xcode builds applications and
frameworks, where it never relies on DYLD_IMAGE_SUFFIX, and instead
uses two separate build directories, one for each configuration.
The change means that Qt Creator will always load the Qt debug
libraries if the application is built in debug mode. For Qt
development this is a good thing, as you expect to be able to
step into Qt code. For our users, the added startup cost can
be mitigated by shipping our binary packages as release-only,
but with separate debug info enabled.
