hey, i am having major problems here. i was testing some code i put into the ldu1 files to get the unit ids. after many installations of the revised ldu1 files my work was halted. first my grc got stuck on start up. now it starts and dies in a flash and prints out like a thousand errors that essentially, i think, say that op25 is not installed; or that it is installed incorrectly.
i have been trying to remedy this all weekend. i uninstalled and reinstalled op25 and gr-baz and grc3.6.3. multiple times. i am fresh out of ideas. i attached the traceback stuff, if you can, please take a peek. any guidance would be much appreciated.

installation gives me this error on make check:

The cause is listed there in the output:
ImportError: /home/matt/op25/blocks/src/lib/.libs/_op25.so: undefined symbol: _ZNK4ldu115destination_strEv
Its a bit cryptic but what its saying is that the code is referring to a new function "ldu1::destination_str()" which isn't in the block you are linking to at runtime using "make check". I guess you added this function to the ldu1 class but not in the ldu1.cc source file?
Stevie
oh right. i commented out 'destination' definition but not the declaration.
