C++ symbols get mangled to arch-specific names. To make the *.symbols file work you need to use the "c++" symbols pattern with the demangled C++ symbol names. E.g. instead of: _ZN4FLAC7Decoder4File13read_callbackEPhPm@Base 1.3.0 use: (c++)"FLAC::Decoder::File::read_callback(unsigned char*, unsigned long*)@Base" 1.3.0 The demangling can be done using c++filt as follows (not sure if there's an automatic way to convert a whole symbols file): % echo "_ZN4FLAC7Decoder4File13read_callbackEPhPm@Base" | c++filt FLAC::Decoder::File::read_callback(unsigned char*, unsigned long*)@Base Alternatively you could use the "regex" symbols pattern, but I don't think it's the recommended way. See dpkg-gensymbols(1) for more info. Cheers
