# Work around global target promotion failure when WrapZLIB is used on APPLE platforms.
# What ends up happening is that the ZLIB::ZLIB target is not promoted to global by qt_find_package,
# then qt_find_package(WrapSystemPNG) tries to find its dependency ZLIB::ZLIB, sees it's not global
# and tries to promote it to global, but fails because the directory scope of the PNG package is
# different (src/gui) from where ZLIB was originally found (qtbase root).
# To avoid that, just manually promote the target to global here.

Enable -mno-direct-extern-access and ELF protected visibility 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.

CMake: Handle automatic rpath embedding correctly Instead of using CMAKE_INSTALL_RPATH to embed an absolute path to prefix/libdir into all targets, use the more sophisticated aproach that qmake does. For certain targets (modules, plugins, tools) use relative rpaths. Otherwise embed absolute paths (examples, regular binaries). Installed tests currently have no rpaths. On certain platforms rpaths are not used (Windows, Android, iOS / uikit). Frameworks, app bundles and shallow bundles should also be handled correctly. Additional rpaths can be provided via QT_EXTRA_RPATHS variable (similar to the -R option that configure takes). Automatic embedding can be disabled either via QT_FEATURE_rpath=OFF or QT_DISABLE_RPATH=ON. Note that installed examples are not relocatable at the moment (due to always having an absolute path rpath), so this is a missing feature compared to qmake. This is due to missing information on where examples will be installed, so a relative rpath can not be computed. By default a Qt installation is relocatable, so there is no need to pass -DQT_EXTRA_RPATHS=. like Coin used to do with qmake e.g. -R . Relative rpaths will have the appropriate 'relative base' prefixed to them (e.g $ORIGIN on linux and @loader_path on darwin platforms). There is currently no support for other platforms that might have a different 'relative base' than the ones mentioned above. Any extra rpaths are saved to BuildInternalsExtra which are re-used when building other repositories. configurejson2cmake modified to include correct conditions for the rpath feature. It's very likely that we will need a new qt_add_internal_app() function for gui apps that are to be installed to prefix/bin. For example for Assistant from qttools. Currently such apps use qt_add_executable(). The distinction is necessary to make sure that relative rpaths are embedded into apps, but not executables (which tests are part of).

Enable -mno-direct-extern-access and ELF protected visibility 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.

CMake: Fix building multi-arch universal macOS Qt Use the same approach we use for iOS, which is to set multiple CMAKE_OSX_ARCHITECTURES values and let the clang front end deal with lipo-ing the final libraries. For now, Qt can be configured to build universal macOS libraries by passing 2 architectures to CMake, either via: -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" or -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" Currently we recommend specifying the intel x86_64 arch as the first one, to get an intel slice configuration that is comparable to a non-universal intel build. Specifying the arm64 slice first could pessimize optimizations and reduce the feature set for the intel slice due to the limitation that we run configure tests only once. The first specified architecture is the one used to do all the configure tests. It 'mostly' defines the common feature set of both architecture slices, with the excepion of some special handling for sse2 and neon instructions. In the future we might want to run at least the Qt architecture config test for all specified architectures, so that we can extract all the supported sub-arches and instruction sets in a reliable way. For now, we use the same sse2 hack as for iOS simulator_and_device builds, otherwise QtGui fails to link due to missing qt_memfill32_sse2 and other symbols. The hack is somewhat augmented to ensure that reconfiguration still succeeds (same issue happened with iOS). Previously the sse2 feature condition was broken due to force setting the feature to be ON. Now the condition also checks for a special QT_FORCE_FEATURE_sse2 variable which we set internally. Note that we shouldn't build for arm64e, because the binaries get killed when running on AS with the following message: kernel: exec_mach_imgact: not running binary built against preview arm64e ABI. Aslo, by default, we disable the arm64 slice for qt sql plugins, mostly because the CI provisioned sql libraries that we depend on only contain x86_64 slices, and trying to build the sql plugins for both slices will fail with linker errors. This behavior can be disabled for all targets marked by qt_internal_force_macos_intel_arch, by setting the QT_FORCE_MACOS_ALL_ARCHES CMake option to ON. To disble it per-target one can set QT_FORCE_MACOS_ALL_ARCHES_${target} to ON.

CMake: Allow building bundled 3rd party libraries in qtbase A few things are needed to accomplish that: - the python scripts do not ignore certain system_foo features anymore (it is a hardcoded list for now just to be safe) - configurejson2cmake now outputs qt_find_package(WrapSystemFoo) calls for bundled libraries (see below) - the harfbuzz .pro file is modified to accommodate pro2cmake not being able to correctly parse some conditional scopes - the freetype .pro file is modified to make sure linking of the library succeeds without duplicate symbol errors, which qmake doesn't encounter due to magical exclusion of cpp files that are included in other cpp files (presumably for include moc_foo.cpp support) - feature evaluation for Core, Gui, Network now happens in the qtbase/src directory, so that bundled libraries can be conditionally built - for each bundled library there are now two FindWrap scripts: - FindWrapSystemFoo which finds an installed library in the system - FindWrapFoo which either uses the system installed library or the built bundled one depending on a condition - projects that intend to use bundled libraries need to link against WrapFoo::WrapFoo instead of WrapSystemFoo::WrapSystemFoo targets (this is handled by pro2cmake). Unfortunately manually added qt_find_package(WrapFoo) calls might still be needed as is the case for WrapFreetype and others. - a new cmake/QtFindWrapHelper.cmake file is added that provides a macro to simplify creation of WrapFoo targets that link against a bundled or system library. The implementation is fairly ugly due to CMake macro constraints, but it was deemed better than copy-pasting a bunch of almost identical code across all FindWrapFoo.cmake files. - a qtzlib header-only module is now created when using bundled zlib, to provide public syncqt created headers for consumers that need them. These are projects that have 'QT_PRIVATE += zlib-private' in their .pro files (e.g. qtimageformats, qtlocation, qt3d, etc.) This is unfortunately needed due to QtNetwork using zlib types in its private C++ API. The change includes support for building the following bundled libraries: - zlib - libpng - libjpeg - Freetype - Harfbuzz-ng - PCRE2 The following 3rd party libraries are still using an old implementation within the CMake build system, and should be migrated to the new one in the near future: - double-conversion - Old harfbuzz The are a few libraries that are not yet ported: - system-sqlite - systemxcb - maybe others Among other things, this change allows building qtbase on Windows without requiring vcpkg.

CMake: Handle automatic rpath embedding correctly Instead of using CMAKE_INSTALL_RPATH to embed an absolute path to prefix/libdir into all targets, use the more sophisticated aproach that qmake does. For certain targets (modules, plugins, tools) use relative rpaths. Otherwise embed absolute paths (examples, regular binaries). Installed tests currently have no rpaths. On certain platforms rpaths are not used (Windows, Android, iOS / uikit). Frameworks, app bundles and shallow bundles should also be handled correctly. Additional rpaths can be provided via QT_EXTRA_RPATHS variable (similar to the -R option that configure takes). Automatic embedding can be disabled either via QT_FEATURE_rpath=OFF or QT_DISABLE_RPATH=ON. Note that installed examples are not relocatable at the moment (due to always having an absolute path rpath), so this is a missing feature compared to qmake. This is due to missing information on where examples will be installed, so a relative rpath can not be computed. By default a Qt installation is relocatable, so there is no need to pass -DQT_EXTRA_RPATHS=. like Coin used to do with qmake e.g. -R . Relative rpaths will have the appropriate 'relative base' prefixed to them (e.g $ORIGIN on linux and @loader_path on darwin platforms). There is currently no support for other platforms that might have a different 'relative base' than the ones mentioned above. Any extra rpaths are saved to BuildInternalsExtra which are re-used when building other repositories. configurejson2cmake modified to include correct conditions for the rpath feature. It's very likely that we will need a new qt_add_internal_app() function for gui apps that are to be installed to prefix/bin. For example for Assistant from qttools. Currently such apps use qt_add_executable(). The distinction is necessary to make sure that relative rpaths are embedded into apps, but not executables (which tests are part of).
