I am unable to run the samples on macOS

If you get one of these error messages, or similar:

dyld: warning, LC_RPATH . in /Users/Username/PDFNetWrappersMac/PDFNetC/Lib/PDFNetRuby.bundle being ignored in restricted program because it is a relative path

Then, the most likely problem is that your Mac OS X operating system has System Integrity Protection enabled, and the LC_RPATH of the PDFNet wrapper files need to be updated.

To fix this issue, try navigating into the /PDFNetC/Lib directory of the Python SDK you downloaded and execute:

./fix_rpaths.sh
