link error in QCoreTextFontDatabase::populateFontDatabase (iOS)

Francky033

I'm trying to compile a program on an old 2012 iPad mini Tablet running under iOS 9.3.5

To do this, I installed Qt 5.9.7 and Xcode 9.3

I get this error message at the linkage level

What can I do to correct this?

Undefined symbols for architecture armv7:
 "_CTFontManagerCopyAvailableFontFamilyNames", referenced from:
     QCoreTextFontDatabase::populateFontDatabase() in libQt5FontDatabaseSupport.a(qcoretextfontdatabase.o)
     QCoreTextFontDatabase::populateFontDatabase() in libQt5FontDatabaseSupport.a(qcoretextfontdatabase.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Thanks,

Hi,

Without recompiling Qt I see two options:

Update your iPad to iOS 10
Find an older version of Qt which doesn't use CTFontManagerCopyAvailableFontFamilyNames.

Unfortunately, it is not possible to update the version of the ipad, it is too old.
Thanks for the advice. I'll give it a try.
