Python Binding Import Error

[tkhamvilai]

I follow Ocarina Python bindings from this document https://readthedocs.org/projects/ocarina/downloads/pdf/latest/
I can import most of the packages except "import libocarina_python"

I keep getting this error
Traceback (most recent call last): File "<string>", line 1, in <module>
ImportError: /home/<my username>/Downloads/ocarina-build/ocarina_install/lib/libocarina-config.so: undefined symbol: __gnat_version

I have GNAT and gnatcoll installed. I think the issue comes from that the ocarina library cannot find these gnat libraries, but I couldn't solve it. Could you help me solve this issue?

Thank you in advance.

The patch above should address this.
