Hi Sara,
C++ is a compiled language; you can not execute a source code file.
You have to recompile the file by rebuilding GNU Radio.
additive_scrambler_bb_impl.cc contains the implementation of the
additive_scrambler_bb block, it is not itself executable.
You need to have a flowgraph containing that block to test your
modified version.
I think you should start with a basic C++ tutorial before you try to
understand and modify GNU Radio's C++ codebase -- these are very basic
concepts you are missing.
Greetings,
Marcus
