... dh_makeshlibs -a dpkg-gensymbols: warning: some new symbols appeared in the symbols file: see diff output below dpkg-gensymbols: error: some symbols or patterns disappeared in the symbols file: see diff output below dpkg-gensymbols: warning: debian/libabsl20200225/DEBIAN/symbols doesn't match completely debian/libabsl20200225.symbols ... Symbols files for C++ libraries are a real pain, unless upstream makes only exported symbols visible: https://gcc.gnu.org/wiki/Visibility When the soname of the library encodes the exact upstream version as abseil does, there are exactly zero benefits of using a symbols - every update of abseil will be a library transition in any case.
