MSGPACK_DEFINE_MAP error

[nobody93]

Hi,

I have a weird error to build following file, if I change MSGPACK_DEFINE_MAP(s, m, r, p, o, t, i) to MSGPACK_DEFINE_MAP(s, m, r, p, i), the error was gone, what was it going on?

class ProvisionRequest { public: ........... MSGPACK_DEFINE_MAP(s, m, r, p, o, t, i)

private: uint64_t s; // Serial number uint16_t m; // message ID uint16_t r; // Rate uint16_t p; // Port number uint16_t o; // OEM ID uint16_t t; // Protocol type ID std::string i; // IP address };

Build caused following error:

Could you post a Minimal, Reproducible Example? https://stackoverflow.com/help/minimal-reproducible-example

Hi redboltz,

Thanks for your response, here are attached source files in tarball code.tar.gz

[redboltz]

It is not complete. Please read again https://stackoverflow.com/help/minimal-reproducible-example carefully.

prog.cc:7:52: error: use of undeclared identifier 'Common'
ProvisionRequest::ProvisionRequest() : MessageBase(Common::Definition::MessageType::INVERTER_OEM_PROVISION), s(0), m(0), r(0), p(0), o(0), t(0) {
                                                   ^
1 error generated.

You need to remove more codes that aren't related to the issue. It should be a single cpp file If you can. And please add int main() `. And please don't attach tar ball. Please write the code in the comment using github comment formatting like as follows:

#include <msgpack.hpp>

int main() {
}

Hi redboltz, I think there is a weird bug in the macro, the error is gone when I changed uint16_t o; to uint16_t e;

Thank you.

It seems that your problem is disappeared. So I close the issue. This is a Minimal, Reproducible Example https://wandbox.org/permlink/KYjXDPA3sdD1F0G3 Please use this in the future issue report.
