using trunk or ddd-3.4.1.tar.gz with applied the patch:

Using nm I saw the missing symbol is in:

    ddd$ nm --defined-only -o *.o | grep app_data
    ddd.o:00000000000001e0 b _ZL16initial_app_data
    resources.o:0000000000000000 B app_data
    resources.o:00000000000003f8 b _ZL20app_data_initializer

Simply adding 'resources.o' to the link command solved the issue.
This seems a failed Makefile
