Building Qaterial on Mac for IOS

[MichaelHeiser]

I have a question regarding building the library for Qt 5.15.12 (builds fine for android and windows within QtCreator)
CMake Error at /Applications/Qt/5.15.12/ios/lib/cmake/Qt5Core/Qt5CoreConfig.cmake:91 (message):
Library not found: MobileCoreServices
Call Stack (most recent call first):
/Applications/Qt/5.15.12/ios/lib/cmake/Qt5Core/Qt5CoreConfig.cmake:263 (_qt5_Core_process_prl_file)
/Applications/Qt/5.15.12/ios/lib/cmake/Qt5/Qt5Config.cmake:28 (find_package)
CMakeLists.txt:96 (find_package)

Can you please give advice? The Components I've created for my App look so great and this would be really amazing to have the planned UI update.

Hello again,

After digging deeper I've found your ios.platform.cmake and included it in my local repository. With this changes and setting the correct cmake options the project configures.
When I now want to build I run into following error:

WriteAuxiliaryFile /Users/TedvG/Documents/Qt/Qaterial/build/Qt_5_15_12_for_iOS/qml/Qaterial/Qaterial.build/Release-iphoneos/QaterialComponents.build/Script-B99CB982058E168055D83A7E.sh (in target 'QaterialComponents' from project 'Qaterial')

Command PhaseScriptExecution failed with a nonzero exit code

The file qrc_Qaterial.o is generated but it has a size of 0 bytes. I tried to execute the shell script on my own also with a failure. Please help me :)

You should have a look at https://github.com/OlivierLDff/QaterialGallery as a starting point

[MichaelHeiser]

When I set the options for cmake exactly as described i get same result. Why rcc generates a 0 byte file? Is there any kind of typo? Should it be qrc_Qaterialtemp.o? This file is generated with 112kb also the Qaterial.qrc is existing.

[MichaelHeiser]

I have an idea:
In the shell script rcc is called to work with /Users/TedvG/Documents/Qt/Qaterial/build/qml/Qaterial/Qaterial.build/Release/rcc_object_Qaterial.build/Objects-normal/arm64/qrc_Qaterialtmp.o
But this file is not existing in the ../Release/.. folder. It is exisiting in ../Release-iphoneos/.. folder. Where can I change this path to only Release?

[OlivierLDff]

You can have a look at https://cmake.org/cmake/help/latest/variable/CMAKE_ARCHIVE_OUTPUT_DIRECTORY.html but i doubt it's the issue. Have you tried using legacy build system? Using -DCMAKE_XCODE_BUILD_SYSTEM=1?

[MichaelHeiser]

Renaming the folder containing the files needed by the shell script to '.../Release-iphoneos/..." solved the issue for me. I will try your answer. Seems to be a problem with https://man.archlinux.org/man/cmake-policies.7.en.
I've updated cmake to v3.25.2 but this did not solve the issue. I will try your suggestion.
My current cmake call for configuration is:
cmake -DCMAKE_PREFIX_PATH=$QT_IOS_DIR -DDEPLOYMENT_TARGET=12.0 -DCMAKE_TOOLCHAIN_FILE=../cmake/ios.toolchain.cmake -DPLATFORM=OS64 -DENABLE_BITCODE=FALSE -G "Xcode" .

[MichaelHeiser]

Setting the flag did not help. Renaming the folder again helped. The combination of $(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME) is not properly recognized for Qaterial components qrc handling.
For info:

cmake -DCMAKE_PREFIX_PATH=$QT_IOS_DIR -DDEPLOYMENT_TARGET=12.0 -DCMAKE_TOOLCHAIN_FILE=../cmake/ios.toolchain.cmake -DPLATFORM=OS64 -DENABLE_BITCODE=FALSE -DCMAKE_XCODE_BUILD_SYSTEM=1 -G "Xcode" ..
