Build system adds this flag to any module that it uses when built as a
shared library and not WASM.
VxWorks is specific in regards to type of applications:
- static application, which do not use any dynamic libraries
- dynamic application, which uses shared libraries, and as such needs
to link against libdl.a
The latter is the only source of symbols related to dynamic loading and
thread local storage. This is an architectural decision, as application
is required to embed loading tools in itself (as opposed to Unix/Linux,
which contains dynamic loader which provides these symbols separately).
libdl.a is standard static library on VxWorks, compiled without PIC, and
as such can't be linked into shared library.
This results in compilation errors when building dynamic libraries which
use `thread_local`-related symbols, since these symbols will be
fulfilled at runtime (contained in executable which requires shared lib)
and are not available during linking.
Don't add `-Wl,--no-undefined` flag on VxWorks for Qt shared lib builds.

uses private API from an inline function:

takes QFutureInterfaceBasePrivate by pointer. Our ELF versioning scripts
mark everything that uses that class as private, resulting in:

Commit 946f15efb7 added the line
extern "C++" { std::* };
but that was too good to be true. The intention was to catch Standard
Library inline symbols that got emitted in our own libraries, not use of
Standard Library types in our symbols. Unfortunately, that glob
expression matches the demangling literally and return types for
templates are demangled in their usual position to the left of the
function name.
For example,
std::random_device qFoo(); // mangles as _Z4qFoov → "qFoo()"
but
template <typename T> T qFoo();
template std::random_device qFoo<std::random_device>();
mangles as _Z4qFooISt13random_deviceET_v and that demangles to
"std::random_device qFoo<std::random_device>()".
Therefore, we replace that with a full expansion according to the
mangling scheme. This includes a minor fix for the RTTI symbols, to
match nested names too (those with "N" in the name). It can't match
virtual override thunks ("Tv" and "Th"), because those have variable
length names and the matching is done by fnmatch(), not regex.

In a previous change, we ensured that all INPUT_foo cache variables are
unset at the end of configuration, so they don't influence feature
re-evaluation in case if a command line flag like -no-gui is not
specified upon second reconfiguration and a FEATURE_foo is manually
toggled in the CMakeCache.txt, effectively getting rid of
stale INPUT_foo values.
Unfortunately that causes an issue when configuring with -no-opengl
and then trying to reconfigure with 'cmake .'
Specifically various feature options like ENABLE / DISABLE use
INPUT_foo variables in their expressions.
qt_configure_add_report_entry CONDITIONs also use them.
These expect the INPUT_foo variables to be persisted, and if they are
removed, the expressions might be re-evaluated to a different value,
and cause re-configuration to fail or unexpectedly toggle features.
To support both cases described above, instead of removing all INPUT
variables when configuration ends, only unset those INPUT variables
whose corresponding FEATURE_foo variable has been manually toggled in
CMakeCache.txt or via an IDE.
Toggling a FEATURE_foo manually is intentional, which means the
INPUT_foo value should be discarded. Whereas pre-existing INPUT_bar
variables will persist, thus not breaking cases like the -no-opengl
report CONDITION.

Before this change, the dirty feature code only checked for

This led to issues in certain scenarios when reconfiguring with the
configure script.
For example configuring with -gui / -DINPUT_gui=ON and then with
-no-gui / -DINPUT_gui=OFF would fail saying
'Feature "widgets": Forcing to "ON" breaks its condition'
This happens because the widgets feature depends on gui being
available, but because INPUT_gui modifications don't trigger the dirty
feature re-eval code, we don't recompute the value of widgets.
Extract the code that takes into account the INPUT_foo variables into
a separate function, and use it both when computing feature values and
also when detecting dirty features.
This means any non-matching INPUT_foo variables will now also trigger

To be able to reconfigure Qt with modified feature values using the
configure script, and take into account INPUT_foo values, we need to
ignore FEATURE_foo values. But we can't always ignore FEATURE_foo
values, because users might want to toggle them by editing
CMakeCache.txt or using an IDE.
What we can do is tell CMake we are configuring via the configure
script, in which case we can mostly be sure that any passed
INPUT_foo values should have higher priority than pre-cached
FEATURE_foo values.
We also need to remove all the cached INPUT_foo variables after they
have been used for feature computation, so that subsequent
reconfigurations where an INPUT_foo is not passed anymore, doesn't
cause a feature to accidentally reuse the previous (stale) value.
Pass -DQT_INTERNAL_CALLED_FROM_CONFIGURE=TRUE to CMake when configuring
via the configure script, and use that as a marker to make INPUT_foo
values have a higher priority.
This needs to be done centrally in qt_evaluate_feature and also in a
few more locations where we check INPUT_ values, like the developer
build and pkgconfig features.
Because QT_INTERNAL_CALLED_FROM_CONFIGURE would become a cached
variable, we want to remove it at the end of the configuration phase,
so that future 'cmake .' reconfigurations are not considered to be done
via configure.
To do that, we unset it right at the end of
qt_build_repo_end in a per-repo build, and in the final
qt_print_build_instructions call in a top-level build.

Previously if Qt was configured with -developer-build, configure
would pass to CMake -DINPUT_developer_build=ON, which will ensure that
both FEATURE_developer_build and QT_FEATURE_developer_build are set to
ON.
Then if somebody tries to toggle FEATURE_developer_build to OFF in
the CMakeCache.txt and rerun cmake, the feature will bounce back to ON,
due to the code in QtSetup.cmake that doesn't take into account if
FEATURE_developer_build is already defined, and thus reset it based
on the value that is cached in INPUT_developer_build.
Change the checks for INPUT_developer_build and INPUT_no_prefix,
to take into account the defined-ness of their
FEATURE_ counterparts.
If they are defined, ignore the INPUT_ values.
This allows toggling the FEATURE_ variables and also aligns with
the INPUT_ handling behavior that we have in qt_evaluate_feature which
ignores INPUT_ values once the FEATURE_ is defined.
While this aligns the behavior with other features, there is still a
problem.
If you first configure without -developer-build,
and FEATURE_developer_build is set OFF, and then reconfigure with
-developer-build, because FEATURE_developer_build is already defined,
the INPUT_developer_build=ON is ignored.

Before this change, if a user toggled a FEATURE_foo variable, we only
recomputed the value for dependent features who's CONDITION would break
with the new value. If the CONDITION was not broken, the dependent
feature value would remain unchanged.
For example if FEATURE_developer_build was OFF, and the user
toggled it to ON, the FEATURE_private_tests value would remain OFF,
because OFF is a valid value for private_tests' CONDITION.
But we would like FEATURE_private_tests to become ON if we toggled
FEATURE_developer_build to ON.
To address this case, we need to recompute features who's dependent
feature values have changed.
The algorithm introduced by this change is:
- keep track of initial dirty features, aka track when FEATURE_foo is
different from QT_FEATURE_foo. We expect FEATURE_foo to be the
variable that a user toggles in the cache file or an IDE.
- when evaluating feature values, collect feature dependencies from
the various expressions given to options like CONDITION, AUTODETECT
- if any feature dependency is marked dirty, reset the feature value
to its auto-computed value and mark the reset feature as dirty
- repeat for all feature evaluations
Because feature evaluation is eagerly recursive, we will successfully
reset all features that need resetting.
To ensure against unforeseen breakages, allow disabling this behavior
by configuring with -DQT_NO_FEATURE_AUTO_RESET=ON
Adjust some of the messages to contain more details.
Note that the pre-existing behavior of resetting feature values when
the condition can't be satisfied, stays. For example if
FEATURE_developer_build is OFF and FEATURE_private_tests is manually
toggled to ON, it will reset to OFF
because its condition can't be satisfied (developer_build is still
OFF).

We've had issues in the past where Standard Library constructs either
with or without a Qt type mangled in the middle get exported from our
ABI and thus get marked with the Qt version numbers. For example, I can
see in our libraries:
517: 000000000010e608 24 OBJECT GLOBAL DEFAULT 22 typeinfo for std::_Sp_counted_base<(__gnu_cxx::_Lock_policy)2>@@Qt_6
615: 00000000000eb2a0 47 OBJECT GLOBAL DEFAULT 17 typeinfo name for std::_Mutex_base<(__gnu_cxx::_Lock_policy)2>@@Qt_6
706: 000000000010e5f8 16 OBJECT GLOBAL DEFAULT 22 typeinfo for std::_Mutex_base<(__gnu_cxx::_Lock_policy)2>@@Qt_6
750: 00000000000ed5f0 16 OBJECT GLOBAL DEFAULT 17 std::_Sp_make_shared_tag::_S_ti()::__tag@@Qt_6
754: 00000000000da408 1 OBJECT GLOBAL DEFAULT 17 std::piecewise_construct@@Qt_6
This causes user content to break when an update to Qt stops exporting
such symbols, either because of code changes or because of changes to
the compiler and its optimizer.
In fact, this commit will cause that, for the symbols above. But this
will no longer be random-looking.
[ChangeLog][Important ABI Changes] On ELF-based platforms (e.g., Linux,
FreeBSD), the linking process has been updated to exclude Standard
Library symbols from getting the "Qt_6" ELF version. This solves the
problem of applications and libraries breaking arbitrarily after Qt
updates, but will cause such breakages right now. Content built with
older versions of Qt may need to be relinked.

This also removes the configure option and therefore makes the feature
not disable-able. Saves 350 ms of CMake time.

In prefix builds of non-qtbase repositories, calls to find_package(Qt6
COMPONENT Foo) did not work in tests, because the find_package calls in
Qt6Config.cmake use NO_DEFAULT_PATH, and thus CMAKE_PREFIX_PATH is
ignored.
Non-external-project examples had the same problem. This was fixed by
ffe0889413 which introduced the variable
QT_EXAMPLES_CMAKE_PREFIX_PATH as additional parameter in all relevant
find_package calls.
We now set this variable in qt_build_tests where it should be local to
the tests directory and its children.
We cannot use QT_ADDITIONAL_PACKAGES_PREFIX_PATH, because it's value is
read once and cached in Qt6Config.cmake - we would have to clear the
internal cache variable.
It would probably be good to rename QT_EXAMPLES_CMAKE_PREFIX_PATH to
reflect that it's not just used for examples. However, my naming skills
are drained for today.

Tests in non-qtbase modules could not find_package their own Qt6*Tools
packages, because add_subdirectory(tests) was called before the config
files for Qt6*Tools were created.
The creation of tools config files is done in QtPostProcess.cmake, which
was included in qt_build_repo_end(). Move that include into its own
macro, qt_build_repo_post_process() and remove it from
qt_build_repo_end(). Call qt_build_repo_post_process() before the
'tests' directory is added in qt_build_repo().
Every call site of qt_build_repo_end() must now be adjusted and call
qt_build_repo_post_process().

When using MinGW compiler and Qt is configured with "-static-runtime",
we should pass "-static" to g++ while linking, like Qt 5, instead of
"-Wl,-Bstatic", to get rid of dependencies on libgcc_s_seh-1.dll,
libwinpthread-1.dll and libstdc++-6.dll.
Because syncqt doesn't link to any Qt library,
"target_link_options(${target} INTERFACE -static)" has no effect on it.
So we should use "PRIVATE" instead of "INTERFACE" for executables.

Consider the following situation: There are CMake tests in
qttools/tests/auto/cmake that configure and build CMake test projects,
essentially as external projects. One of those test projects does
find_package(Qt6 COMPONENTS LinguistTools). This call fails in a prefix
build, because Qt6LinguistToolsConfig.cmake is not installed yet. It
merely exists in qttools-build/lib/cmake/Qt6LinguistTools.
We must adjust CMAKE_PREFIX_PATH to be able to find Qt6LinguistTools. We
also must adjust QT_ADDITIONAL_PACKAGES_PREFIX_PATH to be able to find
the LinguistTools component of the Qt6 package.
Use the prefixes setup from the support for building examples as
external projects and use it for CMake test projects as well.

The density of Q_FOREACH uses in this and some other modules is still
extremely high, too high for anyone to tackle in a short amount of
time. Even if they're not concentrated in just a few TUs, we need to
make progress on a global QT_NO_FOREACH default, so grab the nettle
and stick to our strategy:
Mark the whole of Qt with QT_NO_FOREACH, to prevent new uses from
creeping in, and whitelist the affected TUs by #undef'ing
QT_NO_FOREACH locally, at the top of each file. For TUs that are part
of a larger executable, this requires these files to be compiled
separately, so add them to NO_PCH_SOURCES (which implies
NO_UNITY_BUILD_SOURCES, too).
In tst_qglobal.cpp and tst_qcollections.cpp change the comment on the
#undef QT_NO_FOREACH to indicate that these actually test the macro.
