when i make the paracel, i find an error: Could NOT find MsgpackC (missing: MsgpackC_CHECK_FINE)

Hi @tuhangdi . Where did you install the msgpackC library and include? Could you compile the following codes and successfully run it? If not, what is the error?

g++ -std=c++11 main.cc -lmsgpackC

// main.cc
#include <vector>
#include <msgpack.hpp>
int main(int argc, char *argv[])
{
  std::vector<std::string> target;
  target.push_back("Hello,");
  target.push_back("World!");
  msgpack::sbuffer sbuf;  // simple buffer
  msgpack::pack(&sbuf, target);
  msgpack::unpacked msg;    // includes memory pool and deserialized object
  msgpack::unpack(&msg, sbuf.data(), sbuf.size());
  msgpack::object obj = msg.get();
  std::vector<std::string> result;
  obj.convert(&result);
  return 0;
}

I think you need to install MsgpackC >=1.4.2 like https://github.com/douban/paracel/blob/master/.travis.yml#L49

[tuhangdi]

library path in /usr/local/lib, include path in /usr/local/include, i can compile and run it but output nothing.

[xunzhang]

what is your MsgpackC version: cat /usr/local/include/msgpack/version_master.h?
Could you cat the /home/tuhangdi/paracel-master/build/CMakeFiles/CMakeError.log here?

[tuhangdi]

I had an offline interactive talk with @tuhangdi on Google Hangout, this issue is solved now. Since he installed Msgpack-C v2.1.0 which is not backward compatible.

His error message is below compiling this program:

Instead, users should install MsgpackC v1.4.2 following this.

[zmxdream]

i meet the same problem ,i install MsgpackC v1.4.2, but the problem still occurs
