msgpack_pack_str_body is an inline function. https://github.com/msgpack/msgpack-c/blob/c3df1bb26ebdd01d618ecca7ae2d6b4e37d5abd7/cmake/pack_template.h.in#L782-L785 msgpack_zone_free is not an inline function. https://github.com/msgpack/msgpack-c/blob/c3df1bb26ebdd01d618ecca7ae2d6b4e37d5abd7/src/zone.c#L217-L222 So you need to link the library `libmsgpackc.a`.

See your compiler/linker manual. Usualy `-lmsgpackc`.
