SUMMARY Dbus fails to build on arm64 macOS (Apple sillicon / M1 hardware). STEPS TO REPRODUCE 1. On an arm64 Mac, create a new Craft prefix: > curl https://raw.githubusercontent.com/KDE/craft/master/setup/CraftBootstrap.py -o setup.py && python3 setup.py --prefix ~/CraftRoot 2. Start the prefix: > source ~/CraftRoot/craft/craftenv.sh 3. Install any KDE Framework, I've chosen extra-cmake-modules > craft extra-cmake-modules OBSERVED RESULT While dbus is getting built, you get the following warning and errors: >ld: warning: ignoring file /Users/javier/CraftRoot/lib/libexpat.dylib, building for macOS-arm64 but attempting to link with file built for macOS-x86_64 >ld: warning: ignoring file /Users/javier/CraftRoot/lib/libexpat.dylib, building for macOS-arm64 but attempting to link with file built for macOS-x86_64 >Undefined symbols for architecture arm64: > "_XML_ErrorString", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_GetCurrentColumnNumber", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_GetCurrentLineNumber", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_GetErrorCode", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_Parse", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_ParserCreate_MM", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_ParserFree", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_SetCharacterDataHandler", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_SetElementHandler", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) > "_XML_SetUserData", referenced from: > _bus_config_load in libdbus-daemon-internal.a(config-loader-expat.o) >ld: symbol(s) not found for architecture arm64 >clang: error: linker command failed with exit code 1 (use -v to see invocation) >make[2]: *** [dbus-daemon] Error 1 >make[2]: *** Waiting for unfinished jobs.... >Undefined symbols for architecture arm64: > "_XML_ErrorString", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_GetCurrentColumnNumber", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_GetCurrentLineNumber", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_GetErrorCode", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_Parse", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_ParserCreate_MM", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_ParserFree", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_SetCharacterDataHandler", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_SetElementHandler", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) > "_XML_SetUserData", referenced from: > _bus_config_load in liblaunch-helper-internal.a(config-loader-expat.o) >ld: symbol(s) not found for architecture arm64 >clang: error: linker command failed with exit code 1 (use -v to see invocation) >make[2]: *** [dbus-daemon-launch-helper] Error 1 >make[1]: *** [all-recursive] Error 1 >make: *** [all] Error 2 >Action: compile for libs/dbus:1.14.0 FAILED >*** Craft all failed: libs/dbus after 26 seconds *** >fatal error: package libs/dbus all failed >Craft stopped with out completing ['libs/dbus', 'libs/libzstd', 'libs/libpng', 'dev-utils/nasm', 'libs/libjpeg-turbo', 'libs/sqlite', 'libs/libbzip2', 'libs/pcre2', 'libs/freetype', 'dev-utils/gperf', 'libs/fontconfig', 'libs/pixman', 'libs/cairo', 'libs/harfbuzz', 'dev-utils/flex', 'dev-utils/texinfo', 'dev-utils/help2man', 'dev-utils/bison', 'dev-utils/flexbison', 'libs/qt5/qtbase', 'libs/qt5/qtsvg', 'libs/qt5/qtdeclarative', 'libs/qt5/qttools', 'libs/qt5/qttranslations', 'dev-utils/icoutils', 'kde/frameworks/extra-cmake-modules'] EXPECTED RESULT a) Arm64 binaries are provided and the build completes successfully, outputing an arm64 binary. b) Alternatively, I would expect the source code for all dependencies to be downloaded and compiled locally, also resulting in an arm64 binary. c) If making arm64 binaries for macOS were not a viable option with Qt5, I would expect Craft to successfully output an x86_64 build from the arm64 mac through emulation. SOFTWARE/OS VERSIONS macOS: macOS Monterrey 12.3.1 ADDITIONAL INFORMATION Several months ago, Craft would run on macOS Big Sur and compile x86_64 binaries without an issue on the same hardware.
I've managed to successfully build Qt 5.15.3 and KF5 5.93.0 on macOS Big Sur 11.6 using clang compiler on an M1 Mac. No version of Qt 5.15 (tested 5.15.2 through 5.15.4) can be build on later versions of MacOS because of API changes in macOS 12. You have to use macOS Big Sur to create M1 builds of Qt 5. After getting a working development environment on my system, I went back and tried getting Craft to work with Apple Silicon by making the following changes to `CraftSettings.ini`: > ABI = macOS-arm64-clang > UseCache = False Then attempted to install kcoreaddons by running `craft --no-cache kcoreaddons`. Various dependencies installed successfully, but the build stopped early when glib failed to compile due to architecture mismatch while linking dependency libglib.

>ld: warning: ignoring file /Users/javier/CraftRoot/lib/libexpat.dylib, building for macOS-arm64 but attempting to link with file built for macOS-x86_64 that's the key, it's trying to build a x86_64 build but trying to link to arm libraries. It seems the craft ini file change to arm isn't taking effect in this case. Since it's built with cmake the key is to add https://cmake.org/cmake/help/latest/variable/CMAKE_OSX_ARCHITECTURES.html somehow. Maybe cmake is already setting this (or craft is using cmake to set that) but that's the key.
Tested it, that works with Qt6 and in addition most stuff no longer needs it there thanks to the last patch rounds.
