I am going to guess that you mean this one, https://github.com/romixlab/qmsgpack, probably at the V0.9.9 tag. I am also going to assume that this issue arises when you try to build that library (rather than use that library).
The warning is because the declaration of MsgPack::unpack() in msgpack.h (line 12) does not match the definition of the function in msgpack.cpp (line 10). This would likely be fixed if the definition in msgpack.cpp read:
MSGPACK_EXPORT QVariant MsgPack::unpack(const QByteArray &data)This would be unusual, and something to take up with the author of the module.
Of course, my assumptions could be wrong and you could correct them.
