Consider a cross build of Qt with qtbase, qtshadertools and

Normally, find_package(Qt6Qml) pulls in Qt6QmlTools and errors out if

As of f68e2c92cc, and its follow up
changes, we can now link individual plugins statically, even if the
Qt build is generally a shared build.
This allows us to build Qt for iOS as shared libraries, while still
keeping the platform plugin as a static library, since this is
harder to port over to a shared library.
This gives the benefit of faster turnaround during development, as
well as binary compatibility promises for the main Qt libraries,
without having to go fully shared for all of Qt.
Static builds are still the default, due to the downsides of larger
application bundles and slower load times for shared builds.
For now the user has to manually tick the "Embed & Sign" check
box in Xcode for each Qt library, which is only available with
Xcode projects generated by the qmake Xcode generator.

syncqt.pl adds an extra dependency on perl when building Qt. Modern C++
provides the convenient cross-platform way to access a filesystem and
to use regular expressions, so we may replace the perl script with C++
application. The syncqt executable is built at configure time and
installed as QtCore tool. It's running at configure time to deliver the
required header files for IDE to build a consistent code model and at
the build time to keep tracking changes in header files and generate
the missing aliases without reconfiguring. 'syncqt' only parses header
files from a CMake build tree, so the resulting Qt installation only
contains interfacing headers that belong to the platform that Qt is
built for. 'sync.profile' files are not used as the 'source of truth'
for sync qt procedure anymore, all the necessary information is taken
from either CMake files at configure time or from the module header
files while parsing them.
syncqt.pl is still in place since it's required as fallback solution
for a smooth transition to the new syncqt implementation for all qt
repositories.
This patchset only enables the C++ based syncqt for 'qtbase'
repository.
From the performance perspective C++ version works faster then perl
script, also the configure time is reduced significally on subsequent
reconfigurations - up x2 times faster when re-configuring repository,
but it also takes time to compile the tool itself the first time.
Numbers for qtbase:
syncqt.pl syncqt.cpp
initial: 0m16,035s 0m20,413s
reconfig: 0m6,819s 0m3,725s
The syncing procedure can be run separately for each module using
<ModuleName>_sync_headers targets. The 'sync_headers' target can be
used to sync all the modules at once.

When recording which package version to look for in
QtFooModuleDependencies.cmake and other files like it,
instead of using PROJECT_VERSION, use the version of the
package that contains the dependency.
For example if we're hypothetically building the qtdeclarative repo
from the 6.4 branch, against an installed 6.2 qtbase, then
the Qt6QmlModuleDependencies.cmake file will have a
find_package(Qt6Core 6.2) call because qtdeclarative's
find_package(Qt6Core) call found a 6.2 Core when it was configured.
This allows switching the versioning scheme of specific Qt modules
that might not want to follow the general Qt versioning scheme.
The first candidate would be QtWebEngine which might want to
follow the Chromium versioning scheme, something like
Qt 6.94.0 where 94 is the Chromium major version.
Implementation notes.
We now record the package version of a target in a property
called _qt_package_version. We do it for qt modules, plugins,
3rd party libraries, tools and the Platform target.
When we try to look up which version to write into the
QtFooModuleDependencies.cmake file (or the equivalent Plugins and
Tools file), we try to find the version
from a few sources: the property mentioned above, then the
Qt6{target}_VERSION variable, and finally PROJECT_VERSION.
In the latter case, we issue a warning because technically that should
never have to happen, and it's a bug or an unforeseen case if it does.
A few more places also need adjustments:
- package versions to look for when configuring standalone
tests and generating standalone tests Config files
- handling of tools packages
- The main Qt6 package lookup in each Dependencies.cmake files
Note that there are some requirements and consequences in case a
module wants to use a different versioning scheme like 6.94.0.
Requirements.
- The root CMakeLists.txt file needs to call find_package with a
version different from the usual PROJECT_VERSION. Ideally it
should look for a few different Qt versions which are known to be
compatible, for example the last stable and LTS versions, or just
the lowest supported Qt version, e.g. 6.2.6 or whenever this change
would land in the 6.2 branch.
- If the repository has multiple modules, some of which need to
follow the Qt versioning scheme and some not,
project(VERSION x.y.z) calls need to be carefully placed in
subdirectory scopes with appropriate version numbers, so that
qt_internal_add_module / _tool / _plugin pick up the correct
version.
Consequences.
- The .so / .dylib names will contain the new version, e.g. .so.6.94
- Linux ELF symbols will contain the new versions
- syncqt private headers will now exist under a
include/QtFoo/6.94.0/QtFoo/private folder
- pri and prl files will also contain the new version numbers
- pkg-config .pc files contain the new version numbers
- It won't be possible to write
find_package(Qt6 6.94 COMPONENTS WebEngineWidgets) in user code.
One would have to write find_package(Qt6WebEngineWidgets 6.94)
otherwise CMake will try to look for Qt6Config 6.94 which won't
exist.
- Similarly, a
find_package(Qt6 6.4 COMPONENTS Widgets WebEngineWidgets) call
would always find any kind of WebEngine package that is higher than
6.4, which might be 6.94, 6.95, etc.
- In the future, if we fix Qt6Config to pass EXACT to its
subcomponent find_package calls,
a find_package(Qt6 6.5.0 EXACT COMPONENTS Widgets WebEngineWidgets)
would fail to find WebEngineWidgets, because its 6.94.0 version
will not be equal to 6.5.0. Currently we don't pass through EXACT,
so it's not an issue.

CMake has logic to rewrite build rpaths that contain
CMAKE_STAGING_PREFIX to instead point to CMAKE_INSTALL_PREFIX.
This breaks running executables from the build directory, because
their build rpath will point to a location where the libraries might
not exist yet (we didn't install Qt yet).
Work around this by setting CMAKE_STAGING_PREFIX to a fake path, so
that CMake does not do the rewriting anymore.
CMAKE_STAGING_PREFIX needs to be set at subdirectory scope, not
function scope, which is why
qt_internal_apply_staging_prefix_build_rpath_workaround() is a macro
that is called from within each Qt internal function that creates
a target.
The workaround can be disabled by configuring with
-DQT_NO_STAGING_PREFIX_BUILD_RPATH_WORKAROUND=ON
The downside of this workaround is that it breaks per-subdirectory
install rules like 'ninja src/gui/install'.
Regular global installation like 'ninja install' works fine.
This is similar to what we do for tests in
qt_set_up_fake_standalone_tests_install_prefix()
introduced by 20292250d4
The reason it's not as good for other target types is because in
contrast to tests, we do want to install them.
In case if someone does call `ninja src/gui/install' they will most
likely get a permission error, telling them it's not possible to

When CMake generates compilation rules, it extracts the values from
INTERFACE_INCLUDE_DIRECTORIES and checks if any of the values
are framework paths.
If they are, instead of adding an -I ./lib/My.framework to the
compilation rules, it adds -iframework ./lib or -F ./lib.
The same transformation does not happen when AUTOMOC passes include
paths to moc, nor during a headersclean check. The values there
are passed verbatim, with an -I prepended.
This causes issues when the include file name is the same as the
framework name.
E.g. #include <QtQml> + -I ./lib/QtQml.framework because moc
then ends up silently including the shared library
./lib/QtQml.framework/QtQml
instead of the header
./lib/QtQml.framework/Headers/QtQml
This can lead to a variety of silent issues during moc generation,
because all the definitions of QtQml will be missing.
Unfortunately, there does not seem to be a clean way to fix this in
the build system due to CMake semantics.
See https://gitlab.kitware.com/cmake/cmake/-/issues/23337 for details.
We can mitigate the issue by ensuring that
-I ./lib/QtQml.framework/Headers
comes before
-I ./lib/QtQml.framework
by manipulating the order of values in INTERFACE_INCLUDE_DIRECTORIES.
We might want to consider implementing an additional mitigation in
AUTOMOC, so that it filters out include paths like
-I ./lib/QtQml.framework, thus ensuring that a newer CMake version
will not exhibit the same issue when used with an older Qt.
We could consider doing the same in moc. The advantage of doing it
in moc is that that moc will consider fewer invalid include paths
when searching for headers.

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

Meanwhile, accesses to the same variable in other modules are indirect
via the GOT:
66650: mov 0x876e1(%rip),%rax # edd38 <QCoreApplication::self@Qt_6>

This replaces the -Bsymbolic and -Bsymbolic-functions (broken)

This patch adds pkgconfig generation again via a new internal command
named qt_internal_export_pkg_config_file.
The functionality of this command consists in checking if the target

for dependencies that is somewhat similar to
qt_get_direct_module_dependencies, although it won't recurse down for
more deps. Each dependency is then again, checked if it's internal or
has a public interface. Later these deps get deduplicated and lastly
a pkgconfig file is filled.
The resulting pkgconfig files of many of the Qt6 packages were
validated via invocations of `pkg-config --validate` and
`pkg-config --simulate` commands and later used to build local
projects plus tests that use the pkg-config provided details at
compilation time.
Although it has some limitations, with qt_internal_add_qml_module if
it specifies non-public deps these won't be listed and with non-Qt
requirements, notably in static builds, not being appended to the

The qt_finalize_framework_headers_copy function uses the module
QT_COPIED_FRAMEWORK_HEADERS property to generate the dependency list
for the ${target}_framework_headers target. In a common case elements
can be added to the QT_COPIED_FRAMEWORK_HEADERS property after the
qt_internal_add_module command call, that's why we need to make sure
that qt_finalize_framework_headers_copy is called after collecting all
headers assigned to the module.

When building Qt repos, all find_package(Qt6) calls request a
PROJECT_VERSION version which is set in .cmake.conf via
QT_REPO_MODULE_VERSION.
This means trying to configure qtsvg from a 6.3 branch using a
6.2 qtbase won't work, because qtsvg will call find_package(Qt6 6.3)
and no such Qt6 package version exists.
There are certain scenarios where it might be useful to try to do
that though.
One of them is doing Qt development while locally mixing branches.
Another is building a 6.4 QtWebEngine against a 6.2 Qt.
Allow to opt out of the version check by configuring each Qt repo
with -DQT_NO_PACKAGE_VERSION_CHECK=TRUE. This setting is not
recorded and will have to be set again when configuring another
repo.
The version check will also be disabled by default when configuring
with the -developer-build feature. This will be recorded and embedded
into each ConfigVersion file.
If the version check is disabled, a warning will be shown mentioning
the incompatible version of a package that was found but that package
will still be accepted.
The warning will show both when building Qt or using Qt in a user
project.
The warnings can be disabled by passing
-DQT_NO_PACKAGE_VERSION_INCOMPATIBLE_WARNING=TRUE
Furthermore when building a Qt repo, another warning will show when an
incompatible package version is detected, to suggest to the Qt builder
whether they want to use the incompatible version by disabling the
version check.
Note that there are no compatibility promises when using mixed
non-matching versions. Things might not work. These options are only
provided for convenience and their users know what they are doing.

We don't need to check FEATURE_ltcg, just add -fno-lto unconditionally.
That makes QtCore compile with -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON.

Static libraries don't need to export their symbols, and corner cases
when sources are also used in shared libraries, should be handled
manually.

If qt_internal_generate_cpp_global_exports is called outside the
qt_internall_add_module function scope, install rule that is
generated by qt_internall_add_module won't include generated
cpp export header files. This adds the explicit file-based install
rule for the generated cpp exports.
Since qt_internal_generate_cpp_global_exports now encapsulates all
install rules related to the generated cpp exports, no need to expose
the generated filenames outside the function.
It's expected that module public headers now could be added outside
the qt_internal_add_module function. Tune generating of the module
timestamp by replacing the DEPENDS value with generator expression.

Functions that use qt_internal_add_module under the hood might need to
generate cpp exports, e.g. qt_internal_add_qml_module. Append cpp
exports related arguments to the qt_internal_add_module arguments set.

Add the generating of private cpp exports for Qt modules.
Add the GENERATE_PRIVATE_CPP_EXPORTS option to qt_internal_add_module
that is the manual switch for private exports generator. Existing
modules in qtbase doesn't follow any strict convention of using
private cpp export. So there is no clue how to detect if generating of
the private exports is required or not for the module.
Use autogenerated private cpp exports in QtNetwork module.
CPP_EXPORT_HEADER_NAME argument of the qt_internal_add_module function
is replaced by the CPP_EXPORT_HEADER_BASE_NAME and has a different
meaning. The provided name is used as a base name for the private and
non-private headers that contains cpp exports. Header files suffixes
are constant: .h and _p.h for the non-private and private header files
accordingly.
