We're going to need more information. Are you using cmake or autotools
(Makefile.am) to do this? Are you sure you're editing the .cc, .h, and .i
files, AND are you making sure that the relevant files in your build system
are updated with the correct information?
The error just sounds like you haven't gotten all of the files updated
correctly.
