[Development] Problems porting Qt5.15 to Qt 6.2 for OS/2

[Paul Smedley]

Hi All,

I'm attempting to update the OS/2 port of Qt 5.15 
(https://github.com/bitwiseworks/qtbase-os2) to Qt 6.2.4 
(https://github.com/psmedley/qt6-os2)

Things are going pretty well and I have a number of DLLs built, howeever 
I'm now stuck on building the OS/2 plugin.

I'm getting the following:

AutoMoc subprocess error
------------------------
The moc process failed to compile
   "SRC:/src/plugins/platforms/os2/main.cpp"
into
 
"SRC:/build/src/plugins/platforms/os2/QOS2IntegrationPlugin_autogen/include/main.moc"
included by

Output
------
U:/DEV/qtbase-everywhere-src-6.2.4/src/plugins/platforms/os2/main.cpp:49:1: 
error: Parse error at "IID"

Line 49 of main.cpp contains:
Q_PLUGIN_METADATA(IID QPlatformIntegrationFactoryInterface_iid FILE 
"os2.json")

Any clues on how to resolve the parse error?

Cheers,

Paul
