Make it possible to build the C++ version as a library
Make it possible to build the C++ version as a library
I don't know. I've "librarified" the program in a separate branch that I've pushed now but I'm not happy with it. C++ is a horrible programming language in terms of libraries and linking.
I think I'll just close this issue for now, since according to our e-mail communication there would be no user for this (sub)change, and one can just fork-exec the current pdf-simple-sign binary to get at the same result anyway. I don't have the time to tinker with this all week.
Still, thank you, you've forced me to put everything /else/ back in order. :)
