Re: [gtk-osx-users] GTK2.x issue on macOS High Sierra

Hi Miroslav,

It looks like the zlib you bundle with your app is too old as it doesn’t include the recently added symbol inflateValidate, which is used by recent versions of libpng (like the one that ships with High Sierra).

You will need to rebuild zlib and include the new dylib in your app.

Best,

Tom

Hello,

one of the users reported that my program (bundling GTK2.24.31, built using gtk-osx project) won't start

on macOS High Sierra.

He managed to get it started by clicking on the binary itself (of course, it was not usable), but not through the launcher script (program would not start).

After instructing him to try to run the launcher script from the terminal, he could see these errors:

The domain/default pair of (.GlobalPreferences, AppleCollationOrder) does not exist

dyld: Symbol not found: _inflateValidate

   Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libPng.dylib

   Expected in: /Applications/NotecasePro.app/Contents/Resources/lib/libz.1.dylib in/System/Library/Frameworks/ImageIO.framework/Versions/A/Resources/libPng.dylib

Abort trap 6

App was bundles GTK in 32-bit mode (stable module set), built using (ancient) XCode 4.2 to ensure compatibility with users having OS X 10.6.

Just for a test, user tried to fetch the latest launcher script, but that one failed as well.

Is this a known issue? Any pointers on how to resolve this?

Regards,

  Miroslav
