Undefined symbols for architecture x86_64 when compiling Vidal's 64-bit macoslib

Targets macOS
1

I am trying to compile Vidal’s 64-bit MacOSLib branch and I get a Linking Executable error from Xojo 2018r4.

[code]Linking Executable
Undefined symbols for architecture x86_64:

“__NSGetThemeImage”, referenced from:
_MenuItemWindowMenu.HandleWindowMiniaturize%%oo<Cocoa.NotificationObserver>o<Cocoa.NSNotification> in MenuItemWindowMenu.o
ld: symbol(s) not found for architecture x86_64[/code]

Created a Feedback Case: <https://xojo.com/issue/54890>

You could remove that symbol from the code…

The symbol __NSGetThemeImage does not occur in the code. There is a “_NSGetThemeImage” declare (which is not the same thing), which appears to be a deprecated / private API anyway so perhaps removing this will help. That said, the IDE specifically requests copying the error message into a feedback case when this error occurs. At any rate it’s not a great error message, and I would hope for it to be improved (perhaps highlight the invalid declare rather than just stopping the linking process with a message you can only see by copy/pasting into an external text editor).

Indeed that was the culprit, thanks Christian for the nudge in the right direction.

That’s your hint right there (It is the same thing btw).

Wrap the code for that method in an

#if false ... #endif
block and try again.
