The reason I don't have a makefile is because it's not a trivial thing to compile and I'm not good with makefiles. A makefile would be nice be it's not something I want to produce right now. Anyone is highly welcome to create a makefile however. I do ask that the tree structure of the source and header files remains intact, so you'd need some sort of bash code to work through that (One thing that made me use python instead).
Still, it would be great if we could compile your library with a classic "./configure && make"
I'm not good enough a GNU programmer, but if someone here is, please help.
Meanwhile, I'll read
the automake manual and I'll see what I can do.
Anyway your project really seem like an awesome step towards a GNU version of bitcoin (C language + GNU license). Please keep up.
