First, build the package (the symbol generation needs a compiled library to work):

Then, use dpkg-gensymbols to generate the symbol file. Let’s say here your library name is mylib (replace mylib in the following examples). From the root of your debian package’s source, execute the following command line:

To avoid this, You need to remove everything that’s after the upstream version. Let’s say the package version is 2.0-1, you’ll need to remove all the "-1" after the "2.0" in the symbol file. You can use this command to do the job:

Then, recompile your package and check again with:
