* CMake: Fix rpath-link dependencies when cross-compilingAlexandru Croitor2021-10-201-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Private Qt module dependencies of a Qt module are recorded in the IMPORTED_LINK_DEPENDENT_LIBRARIES property of a Qt module. This property is used to compute the runtime dependency dir path to be passed to the linker via the -rpath-link option. If the referenced target does not exist in the scope where it's used, no -rpath-link will be generated (or at least that specific dir path won't be passed). The linking operation will either fail saying the library is not found, or a different version of the library might be silently picked up in the sysroot or other implicit lib dir. Make sure that QtFooModuleDependencies.cmake calls find_package() for all Qt module private dependencies (or other Qt provided 3rd party libs in the Qt6:: namespace) so that the targets are in scope and IMPORTED_LINK_DEPENDENT_LIBRARIES does its job. qmake also records the INTERFACE_LINK_LIBRARIES of a private Qt module as the runtime dependencies of the module. It's not clear why it does that. A private Qt module is an INTERFACE_LIBRARY so it shouldn't add any new runtime dependencies. Nevertheless, the find_package part of that has been recently addressed in 2b6500cd15c0a41cf3e5eea8178e2044012dbd97 for a different reason. This change is basically the CMake equivalent of 326b91ea788b013512ae911c51cc19497d88916d Pick-to: 6.2 Fixes: QTBUG-86533 Change-Id: Iaf514a14acaded4e8752149cca0c159a271be188 Reviewed-by: Qt CI Bot <qt_ci_bot@qt-project.org> Reviewed-by: Alexey Edelev <alexey.edelev@qt.io> Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>
* QList: deprecate iterator<->pointer implicit conversions (2/3)Giuseppe D'Angelo2021-10-161-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The constructor from a raw pointer should be 1) constexpr, 2) explicit, and 3) *private*. We can do 1) without too much trouble. 2) is a (easy to fix) SIC in case of implicit conversions accidentally relied upon from somewhere. 3) cannot be "easily" fixed by user code (they have to refactor), and also, it's a BIC on Windows which encodes class members' access in symbols. Someone may have been exporting some QList subclass, in turn exporting the iterator classes, and therefore that someone now has the constructors' symbols with a given access. So, don't do 2+3 _just yet_ for user code, but set a deadline: Qt 6.5 is the last that will support this. On Qt 6.6, we switch. All of this on non-Windows, againt to avoid an ABI break. One can opt-in at any time via a suitable define. Given we have this define, use it to guard the other way around as well: conversions from an iterator to a raw pointer should never be explicit (there's std::to_address for this). [ChangeLog][QtCore][QList] Converting a QList's iterator from and to a raw pointer is deprecated, and will get removed in Qt 6.6. User code can prepare for the change by defining QT_STRICT_QLIST_ITERATORS. Change-Id: I0f34bfa3ac055c02af5a3ca159180304660dfc11 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* CMake: Postpone target existence check for qml plugin targetsAlexandru Croitor2021-10-151-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each included qml Qt6FooPluginTargets.cmake file checks whether all the dependency targets that are referenced in the file already exist by the time the file is included. If one of the referenced targets is missing, the file sets ${CMAKE_FIND_PACKAGE_NAME}_NOT_FOUND_MESSAGE with a message mentioning which targets are missing and also sets ${CMAKE_FIND_PACKAGE_NAME}_FOUND to FALSE. All our qml package Config.cmake and Targets.cmake files are include()d by Qt6QmlPlugins.cmake using a file(GLOB) which means the order in which the files are loaded is implementation-defined. Furthermore we didn't check the above set variables after each inclusion, which means the values are overridden and the last plugin to be loaded determines whether the Qml package is found or not. If the last included file sets no error, it effectively silences any previously set error. Ever since we added dependencies between the qml plugin targets themselves, we hit the above situation and depending on the platform, no error was shown because the last file overrode any errors. But we finally got a specific platform (wasm) which unearthed the problem (QTBUG-97478). This can happen for any static Qt build though. To fix this properly, we will most likely have to rewrite the whole inclusion mechanism to use find_package() so that dependencies can be resolved recursively as needed. This is a non-trivial change that will have to be addressed in both qtbase and qtdeclarative. In the mean time, a stop-gap solution that this change implements is to include all the files while ignoring any error messages. Then include the files one more time and check for error message after each included file. All qml plugin targets should have been brought into scope with the first round of inclusions, thus circumventing "missing referenced target" errors, while still catching any other possible errors.

Instead, their recommendation is to adopt the new LLVM-based compiler, which the last commit added support for. This commit does not remove qmake support for the old ICC.

| | | | | | | | | | | | | | | | | | | | | | | | | The .pri files for public Qt modules were missing run_depends entries. Those entries are used by qmake when linking plugins of a static Qt build. In shared builds, run_depends entries are used to decide whether to add the -rpath-link argument to the linker. In that matter, run_depends entries serve a similar purpose as CMake's IMPORTED_LINK_DEPENDENT_LIBRARIES. In Qt5, run_depends entries consist of the qmake values QT_PRIVATE and QT_FOR_PRIVATE. QT_PRIVATE contains the Qt modules that are privately linked to the public module, and QT_FOR_PRIVATE are the dependencies of the private module. That loosely translates to LINK_LIBRARIES of the public module and INTERFACE_LINK_LIBRARIES of the private module. Private modules whose public counterparts are already public dependencies don't have to be added to run_depends.

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.

Even if a user project has a cmake_minimum_required() right at the beginning of the project with a supported version specified, the first project() call which loads a CMake toolchain file could contain another cmake_minimum_required() call with a lower (unsupported) version and that version would be used for the check, failing the project configuration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qt6Config.cmake calls cmake_minimum_required to ensure a recent enough CMake version is used in projects. That call does not set policies in the calling subdirectory scope, because find_package introduces a new policy scope. If a project using Qt has a 'cmake_minimum_required(VERSION 3.1)' call and is configured with a recent CMake, many policies will still be set to OLD. One such policy is CMP0071 (Run AUTOMOC on GENERATED files). The policy value is queried at generation time rather than at target definition time, which means we can't influence the policy value (e.g. inside the implementation of qt_add_executable for example) The inability to influence the policy value for targets created by our own CMake functions is unfortunate and can lead to issues (in the case of the above policy to compilation / linker issues). Record the version of the last cmake_minimum_required call before the Qt packages are found and error out if the version is lower than the minimum supported one. A project can reduce the error into a warning by specifying a -DQT_FORCE_MIN_CMAKE_VERSION_FOR_USING_QT_IN_CMAKE_MIN_REQUIRED=3.xyz option when configuring the project. If the option is used and build issues arise, no official support is given. All the CMake example projects shipped with Qt specify a minimum version of 3.16 already (which is the minimum for shared Qt builds), so it shouldn't be an issue to require that in other user projects as well. Implementation wise, we follow the existing pattern to record what the minimum and computed versions for static and shared Qt builds are at qtbase configure time. These are then checked before the Qt6 or QtFoo packages are find_package'd.

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.

| | | | | | | | | | | | | | | | | In non-prefix builds, we want to prevent users from accidentally running "cmake --install". We did that by replacing cmake_install.cmake with an empty file. The responsible target remove_cmake_install is visible in IDEs, appears in the build output, and the approach is hacky. It's cleaner and easier to add bail out code at the top of cmake_install.cmake. This is now done when calling qt_build_repo_begin. As a bonus, print an informative message on installation.

* CMake: Make standalone tests TestsConfig file repo-target-set specificAlexandru Croitor2021-09-162-3/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Conan CI builds can built a qt repository in a repo-target-set configuration. An example of that is qtscxml. When building standalone tests, qt_build_tests includes a repo specific TestsConfig.cmake file to call find_package on the modules that were built as part of that repo. That doesn't quite work with a repo-target-set build which is enabled when the repo is built with a QT_BUILD_SINGLE_REPO_TARGET_SET value. The TestsConfig.cmake file would be overridden with different contents on each configuration. Fix that by including the QT_BUILD_SINGLE_REPO_TARGET_SET value as part of the TestsConfig.cmake file to be generated and included. This means that when configuring the standalone tests, the same QT_BUILD_SINGLE_REPO_TARGET_SET value should be passed, so that the correct packages are found. Add some debug statements to allow checking which TestsConfig.cmake file is loaded when the standalone tests are configured with --log-level=DEBUG.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We default to configuring examples as separate ExternalProjects when using a developer / non-prefix Qt build. This ensures we test that the examples configure successfully without the pollution of the main Qt build (e.g. already found packages). One down-side of this is that a developer's IDE doesn't see these example targets, unless each project is loaded into the IDE separately. This is cumbersome to do when refactoring or renaming code across multiple example projects. Allow configuring the example projects as part of the main Qt build by setting QT_BUILD_EXAMPLES_AS_EXTERNAL to FALSE when configuring Qt. Save the value of the variable in QtBuildInternalsExtra.cmake.in so it's propagated to leaf repositories as well.
