I saw this warning earlier when trying to build hfst-ospell as a universal binary - it turned out that some binaries were 64 bit only. Now I know that all dependent binaries are universal (both 32 and 64 bit), and as long as the correct architecture is there, there should be no reason to complain.

I did, and nothing has changed, I still get the same warning + errors as long as I am using the *.a file. If I instead reference the *.dylib file (as the rest of the libraries linked with the *.oxt library), the error disappears, but the resulting *.oxt is non-functional on other systems than my own:(

Here's the output of some library debugging tools:

$ otool -L build/oxt/voikko.dylib

Is there something else that is needed to build a static & standalone voikko.oxt?
