The `${wl}' bits look suspicious, but maybe they are expanded OK when
the command is actually run.  If you run these commands by hand, does
that help:

g++ -Wl,-undefined -Wl,dynamic_lookup -o .libs/libxapian_jni.so -bundle .libs/xapian_wrap.o  /usr/local/lib/libxapian.dylib -lstdc++
touch libxapian_jni.la
make

I just tried this myself on Linux, but I get a different error.  In
class DateValueRangeProcessor, one of the constructors (in Java) takes
(long, boolean), which collides with the protected SWIG constructor
taking the same arguments.  That's a bug in SWIG really - it's
currently impossible to wrap a class with a C++ constructor taking
parameters (unsigned long, bool) it would appear.

Perhaps your error has the same cause, but you're using a different
compiler.

If you edit the generated DataValueRangeProcessor.java file by hand and
just delete this constructor entirely, does "make" complete?

  public DataValueRangeProcessor(long valno_, boolean prefer_mdy_) {
    this(XapianJNI.new_DateValueRangeProcessor__SWIG_1(valno_, prefer_mdy_), true);
  }

Cheers,
