simple-static on Windows 10 - ZeroMQ requires ws2_32 and Iphlpapi

joebedard commented 6 years ago

I'm using simple-static in my IDP project (also within CAMP). It seems that ZeroMQ on Windows 10 also requires linking to ws2_32 and Iphlpapi. In my project's CMakeLists.txt, I added ws2_32 and Iphlpapi to target_link_libraries like this:

target_link_libraries(${PROJECT_NAME}
      ${OpenCV_LIBS}
      ${EIGEN3_LIBS}
      ws2_32 #ZeroMQ dependency
      Iphlpapi #ZeroMQ dependency
      simple::simple-static
   )

I followed your install guide (https://github.com/IFL-CAMP/simple/wiki/install:-windows) for ZeroMQ and set ENABLE_CURVE off.

Consider updating the usage page (https://github.com/IFL-CAMP/simple/wiki#cmake) with ws2_32 and Iphlpapi.

My system information: Windows 10 Home, Version 1803 Visual Studio Community 2017, Version 15.6.0 CMake 3.11.2, using generator for Visual Studio 15 2017 Win64

That is very strange, since the CI runs for VS15 as well. And I also never experienced that on Windows 10. Do you maybe use Windows 10 32-bit? Also that "ws2_32" suggests it.

Everything is 64-bit. I'm using Windows SDK 10.0.16299.0. Without ws2_32 and Iphlpapi, I get link errors such as:

2>libzmq-v141-mt-s-4_2_3.lib(zmq.obj) : error LNK2019: unresolved external symbol __WSAFDIsSet referenced in function zmq_poll
2>libzmq-v141-mt-s-4_2_3.lib(socket_poller.obj) : error LNK2001: unresolved external symbol __WSAFDIsSet
2>libzmq-v141-mt-s-4_2_3.lib(select.obj) : error LNK2001: unresolved external symbol __WSAFDIsSet

Oh wait! Are you using libzmq 4.2.3 (I'm guessing from the name of the lib files)? simple required ZeroMQ 4.2.4+!

joebedard commented 6 years ago

Ah! Yes I was. Thanks for catching that!
