Windows compilation

For Cameo 2.0, the compilation for Windows is reviewed. Here is the current status. The compilations have been made on sci-windows with the legoc account.

Prerequisites:

  • Visual Studio 19
  • Cmake 3.19

ZeroMQ 4.3.3

  1. Create the directory build in zeromq-4.3.3

  2. Launch cmake-gui

    • Source code: C:/Users/legoc/Documents/zmq/zeromq-4.3.3
    • Build: C:/Users/legoc/Documents/zmq/zeromq-4.3.3/build
    • Configure, Generate, Open Project (launches Visual Studio 19)

  3. In Visual Studio 19

    • Switch to Release Configuration
    • Generate Solution
      • The generated dll file is in build/bin/Release
      • The generated lib file is in build/lib/Release

JZMQ

It must be built with the version of ZeroMQ. Follow the instructions at https://github.com/zeromq/jzmq.
HTTP_PROXY and HTTPS_PROXY must be set to clone the project.

$ cmake -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON .. -G "NMake Makefiles" -DZMQ_C_INCLUDE_PATH=C:\Users\legoc\Documents\zmq\zeromq-4.3.3\include -DZMQ_C_LIB_PATH=C:\Users\legoc\Documents\zmq\zeromq-4.3.3\lib

Curious: Found JNI: in jdk 1.8 and not 10 like Java

$ nmake

Terminates with the error when generating files from native methods: could not find class file for org.zeromq.ZMQ

By trying to compile on another computer, it was another error at the previous stage (building zmq.jar).

To do:

  • Remove the jdk 1.8 and retry the process.
  • Try to fix the errors that must come from the configuration files that must be updated.

We have two options:

  • Do not use JZMQ on Windows and use JeroMQ instead, hoping that it is stable enough for our puposes.
  • Still use the old ZeroMQ 4.0.5, but that means compiling cameo-api-cpp with ZeroMQ 4.0.5.

RapidJSON

Version 1.1.0 in C:/Users/legoc/Documents/zmq/rapidjson-1.1.0

Cameo API C++

  1. Create the directory build in cameo-api-cpp

  2. Create C:/Users/legoc/Documents/zmq/zeromq-4.3.3/lib

    • Copy C:/Users/legoc/Documents/zmq/zeromq-4.3.3/build/lib/Debug/libzmq-v142-mt-gd-4_3_3.lib to it
    • Copy C:/Users/legoc/Documents/zmq/zeromq-4.3.3/build/lib/Release/libzmq-v142-mt-4_3_3.lib to it
    • Indeed the script FindZeroMQ.cmake is searching for ZMQ_ROOT/lib/*.lib

  3. Launch cmake-gui

    • Source code: C:/Users/legoc/workspace/cameo/cameo-api-cpp

    • Build: C:/Users/legoc/workspace/cameo/cameo-api-cpp/build

    • Options:

      • _ZeroMQ_ROOT C:\Users\legoc\Documents\zmq\zeromq-4.3.3
      • ZeroMQ_LIBRARY_RELEASE C:\Users\legoc\Documents\zmq\zeromq-4.3.3\lib\libzmq-v142-mt-4_3_3.lib
      • ZeroMQ_LIBRARY_DEBUG C:\Users\legoc\Documents\zmq\zeromq-4.3.3\lib\libzmq-v142-mt-gd-4_3_3.lib

    • Configure, Generate, Open Project (launches Visual Studio 19)

      • Generate cameo-api-cpp-static
      • Files generated:
        • C:\Users\legoc\workspace\cameo\cpp\api\build\cameo-api-cpp-obj.dir\Debug\cameo-api-cpp-obj.lib
        • C:\Users\legoc\workspace\cameo\cpp\api\build\cameo-api-cpp-obj.dir\Release\cameo-api-cpp-obj.lib

Problems

  • The rapidjson include directory is not added to the include paths
  • The zmq include directory is not added to the include paths
  • The file zmq.hpp does not exist in zeromq-4.3.3 (it is in the Linux package): we copy it from Linux in zmq/ and add zmq/ to the include paths

Corrections

  • Added the include paths to cameo-api-cpp-obj: C:\Users\legoc\Documents\zmq;C:\Users\legoc\Documents\zmq\zeromq-4.3.3\include Notes
  • It would be better to add an optional property to specify where is the zmq.hpp file that could be downloaded or cloned
  • It should be possible to use nmake to compile in command-line

Cameo API C++ Tests

$ set PATH=C:\Users\legoc\Documents\zmq\bin\4.3.3;%PATH%

The tests were not run yet.

Protocol Buffers

The library is no longer required to compile Cameo API C++ but it is used in the Cameo Dielectrics program.

  1. Create the directory C:/Users/legoc/Documents/zmq/protobuf-3.12.4/cmake/build

  2. Launch cmake-gui

    • Source code: C:/Users/legoc/Documents/zmq/protobuf-3.12.4/cmake
    • Build: C:/Users/legoc/Documents/zmq/protobuf-3.12.4/cmake/build
    • Configure, Generate, Open Project (launches Visual Studio 19)

Notes

  • The documentation suggests to use nmake however using it compiles the library in x86 format. Maybe an option is missing.
  • It was necessary to switch the flag Runtime Library from /MT to /MD to conform to the other projects. Then only the libprotobuf.lib is linking.
