The compiled library is presently named just libvoikko.1.dylib (as opposed to libvoikko.1.7.0dylib or libvoikko.1.11.0dylib), with no further version info in the filename - I don't know whether that has any significanse. But based on the error message, I guess that the file is found, and that XCode tries to link against it. That leads us to the second problem.

Explicitly setting the architecture to 64-bit Intel (x86_64) made it:) No warnings, no errors. Remains to be seen whether it works as it should. Both release and debug versions built fine.

The unfortunate thing is that I'm not able to build for other architectures, or older OS-es. We'll have to return to that later.

Now off to test it:)

Best,
