macos - Mac OS X Archive (.app) crashed on test Mac machine: EXC_BAD_INSTRUCTION

Question

I am working on a Mac application, which is running fine on my machine which is a development machine. The project has quite a few dylib files, the dependancies for which I had to solve using

install_name_tool -change

I used @executable_path in the above command. After doing this, the program works fine on my machine, when I move the .app file to test environment it fails..

Looking at the bold characters one can make out that the problem is in freetype dylib. But why is it giving problems? I have included the .dylib file in the my_app.app/Contents/Frameworks/ directory.

Is this why the problem is caused?

Answer 1

This error is seen because the location of the font supplied to freetype was incorrect.

The client did not have the supplied font file (ttf) on his machine.

When I supplied the ttf file along with the bundle, it was fixed.!
