# building Qt from source.

Make standalone tests build via top level repo project Previously repo/tests/CMakeLists.txt was a standalone project on which CMake could be called. This was useful for Coin to be able to build and package only tests, but was a bit troublesome because that means having to specify the usual boilerplate like minimum CMake version, which packages to find in every tests.pro project. Instead of having a separate standalone project, modify the top level project and associated CMake code to allow passing a special QT_BUILD_STANDALONE_TESTS variable, which causes the top level project to build only tests, and find Qt in the previously installed qt location. This also means that when building a repo, we generate a ${repo_name}TestsConfig.cmake file which does find_package on all the modules that have been built as part of that repo. So that when standalone tests bare built for that repo, the modules are automatically found. qt_set_up_standalone_tests_build() is modified to be a no-op because it is not needed anymore. Its usage should be removed from all the other repos, and then removed from qtbase. Non-adjusted tests/CMakeLists.txt projects in other repositories should still be buildable with the current code, until they are updated to the new format. Adjust the Coin build instructions to build the standalone tests in a separate directory. Adjust pro2cmake to generate new structure for the tests/tests.pro projects. Adjust the qtbase tests project.

CMake: Get toolchain file path from EMSDK env for Wasm user projects Try to to chainload the emscripten CMake toolchain file from the EMSDK env var if it is set, instead of requiring the user to explicitly specify a path to the file via QT_CHAINLOAD_TOOLCHAIN_FILE. The order in which the toolchain file is chainloaded becomes is as follows: 1) The initial toolchain file path that was specified when configuring qtbase is set written as the initial value of __qt_chainload_toolchain_file in qt.toolchain.cmake 2) If EMSDK env var is set, it overrides the value from 1) 3) If QT_CHAINLOAD_TOOLCHAIN_FILE cache var is supplied it overrides the value from 2) Whichever value ends up in __qt_chainload_toolchain_file is checked too see if the file exists. If it exists it gets included, if it doesn't, a warning is issued. This checking logic is a bit crude and should be improved and unified with the Android chainload checking, but the current change already improves the behavior for users of Qt.

Also, NDK r23b seems to have removed the part of code from android.toolchain.cmake that handles ANDROID_NATIVE_API_LEVEL to set the correct value to ANDROID_PLATFORM. With this change, CMake will pass the value from the configure argument -android-ndk-platform as -DANDROID_PLATFORM instead of -DANDROID_NATIVE_API_LEVEL. Otherwise, if if -DANDROID_NATIVE_API_LEVEL is passed directly to CMake, it should work as before.

Make standalone tests build via top level repo project Previously repo/tests/CMakeLists.txt was a standalone project on which CMake could be called. This was useful for Coin to be able to build and package only tests, but was a bit troublesome because that means having to specify the usual boilerplate like minimum CMake version, which packages to find in every tests.pro project. Instead of having a separate standalone project, modify the top level project and associated CMake code to allow passing a special QT_BUILD_STANDALONE_TESTS variable, which causes the top level project to build only tests, and find Qt in the previously installed qt location. This also means that when building a repo, we generate a ${repo_name}TestsConfig.cmake file which does find_package on all the modules that have been built as part of that repo. So that when standalone tests bare built for that repo, the modules are automatically found. qt_set_up_standalone_tests_build() is modified to be a no-op because it is not needed anymore. Its usage should be removed from all the other repos, and then removed from qtbase. Non-adjusted tests/CMakeLists.txt projects in other repositories should still be buildable with the current code, until they are updated to the new format. Adjust the Coin build instructions to build the standalone tests in a separate directory. Adjust pro2cmake to generate new structure for the tests/tests.pro projects. Adjust the qtbase tests project.

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).

Add initial support for CMake "Ninja Multi-Config" generator This allows doing debug_and_release builds with Ninja on all platforms. The "Ninja Multi-Config generator" is available starting with CMake 3.17. Desired configurations can be set via CMAKE_CONFIGURATION_TYPES. Possible values: "Release, Debug, RelWithDebInfo, MinRelSize". For example -DCMAKE_CONFIGURATION_TYPES="Release;Debug". The first configuration is the 'default' configuration which is built when calling ninja with no arguments. To build all targets of a certain configuration use "ninja all:Release" or "ninja all:Debug". To build all targets in all configurations use "ninja all:all". Note that the first configuration influences which configuration of tools will be used when building the libraries for all configurations. In simple terms, when configured with -DCMAKE_CONFIGURATION_TYPES="Release;Debug" the release version of moc is used by AUTOMOC. When configured with -DCMAKE_CONFIGURATION_TYPES="Debug;Release" the debug version of moc is used by AUTOMOC. Framework builds and Ninja Multi-Config don't currently work together due to multiple bugs in CMake, which ends up generating an invalid ninja file with duplicate rules. There are also issues with placement of the debug artifacts. This will be handled in a follow up patch after CMake is fixed.

Add initial support for CMake "Ninja Multi-Config" generator This allows doing debug_and_release builds with Ninja on all platforms. The "Ninja Multi-Config generator" is available starting with CMake 3.17. Desired configurations can be set via CMAKE_CONFIGURATION_TYPES. Possible values: "Release, Debug, RelWithDebInfo, MinRelSize". For example -DCMAKE_CONFIGURATION_TYPES="Release;Debug". The first configuration is the 'default' configuration which is built when calling ninja with no arguments. To build all targets of a certain configuration use "ninja all:Release" or "ninja all:Debug". To build all targets in all configurations use "ninja all:all". Note that the first configuration influences which configuration of tools will be used when building the libraries for all configurations. In simple terms, when configured with -DCMAKE_CONFIGURATION_TYPES="Release;Debug" the release version of moc is used by AUTOMOC. When configured with -DCMAKE_CONFIGURATION_TYPES="Debug;Release" the debug version of moc is used by AUTOMOC. Framework builds and Ninja Multi-Config don't currently work together due to multiple bugs in CMake, which ends up generating an invalid ninja file with duplicate rules. There are also issues with placement of the debug artifacts. This will be handled in a follow up patch after CMake is fixed.

CMake: Protect against Qt toolchain file recursive inclusion Three different people have encountered the issue that calling calling qt-cmake on a project prints 1000 inclusion lines of the same qt toolchain file, and then CMake bails out saying can't find the CMAKE_MAKE_PROGRAM Ninja. This happened because people accidentally called qt-cmake to configure qtbase (instead of just cmake), which created a toolchain file that chainloads itself recursively. Error out when configuring qtbase, and when using the generated toolchain file in the case when it would try to include itself. The solution is to remove the qtbase CMakeCache.txt file, and configure qtbase again, so it generates a proper qt.toolchain.cmake file. If somebody feels enthusiastic, they can move the check into the qt-cmake and qt-cmake-private shell scripts, and error out before the qtbase/CMakeCache.txt is polluted with the wrong toolchain file. That is left for people that feel more comfortable with bash and batch scripting. Change-Id: If518c94791fe7c30731e6e462e347f26a5213c64 Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>

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: Handle detection of linux-g++-32 mkspec If Qt is configured with -platform linux-g++-32 , make sure to add the -m32 compile options for all built targets. On 64 bit host OSes that provide both 32 and 64 bit libraries we need to exclude the 64 bit libraries from being picked up. The locations of the libraries are distro-specific. This change by default excludes the Ubuntu x86_64 libraries paths. Opt outs are provided, which when used, forces Qt builders to specify their own ignore paths in a custom CMake toolchain file. The compile option and default path exclusions are added to the Qt-generated CMake toolchain file as well, so they are reused when building other Qt repositories. Note that there is no foolproof way to tell CMake to ignore all x86_64 packages / libraries, even if CMake 3.23 CMAKE_IGNORE_PREFIX_PATH is used, because there might not be a single sysroot to exclude. Both x86 and x86_64 libraries can co-exist in the same sysroot, e.g in /usr One would have to list each package / library directory in CMAKE_IGNORE_PATH manually. Additionally, the PKG_CONFIG_LIBDIR environment variable is also set to Ubuntu specific prefixes, to ensure that pkg_check_modules -> pkg-config don't pickup x86_64 libraries.

# The problem is that if no 32 bit library is found, a 64 bit one might get picked up.
# That's why we need to specify additional ignore paths.
#
# The paths used in the code below are Ubuntu specific.
# You can opt out of using them if you are using a different distro, but then you need to
# specify appropriate paths yourself in your own CMake toolchain file.
#
# Note that to absolutely ensure no x86_64 library is picked up on a multiarch /
# multilib-enabled system, you might need to specify extra directories in
# CMAKE_INGORE_PATH for each sub-directory containing a library.
#
# For example to exclude /usr/lib/x86_64-linux-gnu/mit-krb5/libgssapi_krb5.so
# you need to add /usr/lib/x86_64-linux-gnu/mit-krb5 explicitly to CMAKE_IGNORE_PATH.
# Adding just /usr/lib/x86_64-linux-gnu to either CMAKE_IGNORE_PATH or
# CMAKE_IGNORE_PREFIX_PATH is not enough.
#
# Another consideration are results returned by CMake's pkg_check_modules which uses
# pkg-config.
# CMAKE_IGNORE_PATH is not read by pkg_check_modules, but CMAKE_PREFIX_PATH
# values are passed as additional prefixes to look for .pc files, IN ADDITION to the default
# prefixes searched by pkg-config of each specific distro.
# For example on Ubuntu, the default searched paths on an x86_64 host are:
# /usr/local/lib/x86_64-linux-gnu/pkgconfig
# /usr/local/lib/pkgconfig
# /usr/local/share/pkgconfig
# /usr/lib/x86_64-linux-gnu/pkgconfig
# /usr/lib/pkgconfig
# /usr/share/pkgconfig
# To ensure the x86_64 packages are not picked up, the PKG_CONFIG_LIBDIR environment
# variable can be overridden with an explicit list of prefixes.
# Again, the paths below are Ubuntu specific.

CMake: Ensure that UNIX is set for INTEGRITY Certain platform-related variables, in this case UNIX, must be set in a platform module, because they get cleared after the toolchain file is loaded. Such platform modules live in upstream CMake, but there is none yet for INTEGRITY. This manifests in an undefined UNIX variable and "System is unknown to CMake" warnings for the project and every configure test. Add the CMake module "Platform/Integrity" in the cmake/platforms directory. Add this directory to CMAKE_MODULE_PATH to let CMake load Platform/Integrity when the toolchain file set CMAKE_SYSTEM_NAME to "Integrity". CMake's module directory takes precedence, when loading platform modules. This is special for platform modules and different from the documented behavior of CMAKE_MODULE_PATH and include(). In case the user wants to provide their own platform modules via CMAKE_MODULE_PATH, they can instruct Qt to not add its path by setting QT_AVOID_CUSTOM_PLATFORM_MODULES to ON. Make sure that configure tests with project files also load the custom platform module.

CMake: Protect against Qt toolchain file recursive inclusion Three different people have encountered the issue that calling calling qt-cmake on a project prints 1000 inclusion lines of the same qt toolchain file, and then CMake bails out saying can't find the CMAKE_MAKE_PROGRAM Ninja. This happened because people accidentally called qt-cmake to configure qtbase (instead of just cmake), which created a toolchain file that chainloads itself recursively. Error out when configuring qtbase, and when using the generated toolchain file in the case when it would try to include itself. The solution is to remove the qtbase CMakeCache.txt file, and configure qtbase again, so it generates a proper qt.toolchain.cmake file. If somebody feels enthusiastic, they can move the check into the qt-cmake and qt-cmake-private shell scripts, and error out before the qtbase/CMakeCache.txt is polluted with the wrong toolchain file. That is left for people that feel more comfortable with bash and batch scripting. Change-Id: If518c94791fe7c30731e6e462e347f26a5213c64 Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>

Add initial support for CMake "Ninja Multi-Config" generator This allows doing debug_and_release builds with Ninja on all platforms. The "Ninja Multi-Config generator" is available starting with CMake 3.17. Desired configurations can be set via CMAKE_CONFIGURATION_TYPES. Possible values: "Release, Debug, RelWithDebInfo, MinRelSize". For example -DCMAKE_CONFIGURATION_TYPES="Release;Debug". The first configuration is the 'default' configuration which is built when calling ninja with no arguments. To build all targets of a certain configuration use "ninja all:Release" or "ninja all:Debug". To build all targets in all configurations use "ninja all:all". Note that the first configuration influences which configuration of tools will be used when building the libraries for all configurations. In simple terms, when configured with -DCMAKE_CONFIGURATION_TYPES="Release;Debug" the release version of moc is used by AUTOMOC. When configured with -DCMAKE_CONFIGURATION_TYPES="Debug;Release" the debug version of moc is used by AUTOMOC. Framework builds and Ninja Multi-Config don't currently work together due to multiple bugs in CMake, which ends up generating an invalid ninja file with duplicate rules. There are also issues with placement of the debug artifacts. This will be handled in a follow up patch after CMake is fixed.

qt_auto_detect_darwin()
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: Handle detection of linux-g++-32 mkspec If Qt is configured with -platform linux-g++-32 , make sure to add the -m32 compile options for all built targets. On 64 bit host OSes that provide both 32 and 64 bit libraries we need to exclude the 64 bit libraries from being picked up. The locations of the libraries are distro-specific. This change by default excludes the Ubuntu x86_64 libraries paths. Opt outs are provided, which when used, forces Qt builders to specify their own ignore paths in a custom CMake toolchain file. The compile option and default path exclusions are added to the Qt-generated CMake toolchain file as well, so they are reused when building other Qt repositories. Note that there is no foolproof way to tell CMake to ignore all x86_64 packages / libraries, even if CMake 3.23 CMAKE_IGNORE_PREFIX_PATH is used, because there might not be a single sysroot to exclude. Both x86 and x86_64 libraries can co-exist in the same sysroot, e.g in /usr One would have to list each package / library directory in CMAKE_IGNORE_PATH manually. Additionally, the PKG_CONFIG_LIBDIR environment variable is also set to Ubuntu specific prefixes, to ensure that pkg_check_modules -> pkg-config don't pickup x86_64 libraries.
