我正在把一个项目从Qt5转换到macOS上的Qt6.11，使用QMake。
我的.PRO文件指定了：

QT += core gui help uitools  widgets printsupport network xml sql

Platforms.files += $$(QTDIR)/plugins/platforms/libqcocoa.dylib
Styles.files += $$(QTDIR)/plugins/styles/libqmacstyle.dylib
Imageformats.files += $$(QTDIR)/plugins/imageformats/libqico.dylib \
    $$(QTDIR)/plugins/imageformats/libqgif.dylib \
    $$(QTDIR)/plugins/imageformats/libqjpeg.dylib \
    $$(QTDIR)/plugins/imageformats/libqsvg.dylib

QTDIR解析为：

/Users/me/Qt6/6.11.1/macos

我遇到了以下错误：

unsupported mach-o filetype (only MH_OBJECT and MH_DYLIB can be linked) in '../MyApp.app/Contents/Plugins/platforms/libqcocoa.dylib'
unsupported mach-o filetype (only MH_OBJECT and MH_DYLIB can be linked) in '../MyApp.app/Contents/Plugins/imageformats/libqico.dylib'

unsupported mach-o filetype (only MH_OBJECT and MH_DYLIB can be linked) in '../MyApp.app/Contents/Plugins/sqldrivers/libqsqlite.dylib'

为什么Qt要对它自己的动态链接库提出异议？我在编译前会删除MyApp.app文件夹。它是在编译阶段构建的，推测这些.dylib来自QTDIR？

我该如何让它完成链接？

解决方案

我问了ChatGPT，解决方案是在.PRO文件中删除以下几行：

PrintSupport.files += $$(QTDIR)/plugins/printsupport/libcocoaprintersupport.dylib
PrintSupport.path = Contents/Plugins/printsupport
Platforms.path = Contents/Plugins/platforms
Platforms.files += $$(QTDIR)/plugins/platforms/libqcocoa.dylib
Styles.path = Contents/Plugins/styles
Styles.files += $$(QTDIR)/plugins/styles/libqmacstyle.dylib
Imageformats.path = Contents/Plugins/imageformats

-L"MyApp.app/Contents/Plugins/platforms" -lqcocoa \

ChatGPT提醒我如下：
"在macOS的 Qt6中，插件二进制文件不再是普通的.dylib文件"
"让Qt部署这些插件。"
"你的链接器明确地尝试将插件链接到可执行文件中。"
