VC Compiler Error while including messagepack

[Christian Kungel]

Hello Guys,

i just want to test message pack as a serialization format to transmit binary (image) data over network (ethernet).
I've started and included the messagepack and i want to take the existing json serialization from my project to convert json to message pack before sending the data over the network to just minimize the payload on the wire.
But if i include the c++ header (its a c++ project ...), i become errors in due to
"error C2371: 'int8_t': Neudefinition; unterschiedliche Basistypen   stdint.h".

Any hints in due to that issue? Is it known here?

All the best,
Christian
