macqtdeploy.... cmake... ARM/M1 to intel... oh dear...

[Dariusz]

Hey

Ok So I'm trying to solve 2 problems here.

1. Compile on ARM and hope that Intel can run my binary.
2. Pack it up and send to my friend.

So I've recently read that latest macos Monterey is automatically compiling universal binaries and it should work on any other 12.0+ mac. But when I send file to my friend he cant execute it.

As to packing it up, the packer "worked" but I cant run the app after he packed it... I get a bit of a crazy log with lots of :

Toolbox.app/Contents/Frameworks/QtSvg.framework/Versions/A/QtSvg (architecture arm64):"

ERROR: Could not parse otool output line: "/Users/dariusz/Qt/6.2.2/macos/lib/QtCore.framework/Versions/A/QtCore (architecture arm64):"

When I inspect the app, it appears to have worked, the bundle has data and files and exe is relinked, but it somehow give me error when I run it

"toolbox.app quit unexpectedly. click to report bla bla bla"

Does any of this means to any1 ?

I'm lost.

Hi,

Can you explain the steps you took to build your .dmg ?
One thing is not completely clear, does it also happen on your own machine ?

[DerReisende]

@Dariusz you can ignore the otool messages if I remember correctly. There has been a bug report on Qt for this and it is basically the script doesn't parse all output of arm64 otool correctly.

Hey @SGaist
I've finally found the willpower to fight with mac again... lots of good fixes with the intel&arm build on my end but sadly still issue with QT...
Here is my cmake...>

cmake_minimum_required(VERSION 3.22)
project(02_qt6Deploy)

set(CMAKE_CXX_STANDARD 20)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_OSX_ARCHITECTURES "arm64;x86_64" CACHE INTERNAL "" FORCE)

set(QT_PATH  /Users/dariusz/Qt/6.3.0/macos/)

set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} ${QT_PATH} )

find_package(Qt6 COMPONENTS
        Core
        Gui
        Widgets
        REQUIRED)

add_executable(02_qt6Deploy MACOSX_BUNDLE main.cpp)
target_link_libraries(02_qt6Deploy
        Qt::Core
        Qt::Gui
        Qt::Widgets
        )

add_custom_target(deployRuntimeMac
        ALL
        COMMAND
        ${QT_PATH}/bin/macdeployqt ${PROJECT_BINARY_DIR}/${PROJECT_NAME}.app
        )

Here is my error :

ERROR: "error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: \"-delete_rpath /Users/dariusz/Qt/6.3.0/macos/lib\" specified more than once\nUsage: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool [-change old new] ...

ERROR: ""

The app works, if I do NOT pass set(CMAKE_OSX_ARCHITECTURES "arm64;x86_64" CACHE INTERNAL "" FORCE)
Looks like macdeployqt does not know how to handle universal libraries/binaries with combined platforms?

[SGaist]

If memory serves well there was a thread recently on the development mailing about something similar. You might want to check it.

[Dariusz]

@SGaist Any idea where/how to find it? I've never been there before : O

[SGaist]

The mailing list is here.

@Dariusz I'm experiencing this same issue on Mac M2 with Qt 6.4.2, however the same code build on Mac Intel works fine and I don't have that ugly output.

[Gleb.Ignatev]

If anyone interested, the reason behind that error is that you apparently cannot run unsigned apps on M-chips: https://github.com/orgs/Homebrew/discussions/3088.

To fix this just self-sign the app bundle:

sudo codesign --force --deep -s - toolbox.app
