AttributeError：Windows中的Boost.Python和CMake模块没有属性

Question

简介

我目前正在通过 Windows x64 支持扩展我的Linux构建（可以正常工作2年），并且遇到 boost.python 模块的问题。我使用 CMake 构建代码（请参见我使用的cmake脚本的快照），这为我提供了无法加载的 CppCudaPyModule.dll 共享库。带有消息AttributeError: module has no attribute的 boost.python 模块（请参见下面的完整错误）。

  

平台详细信息：   我在 Windows Server2016 上工作，使用 Anaconda 3.6 x64 ，并使用 msvc-14.0 重建boost和boost.python。

问题

在linux上，boost.python模块可以正常工作。我怀疑我在Windows中使用CMAKE 无法正确构建该DLL。有什么想法会出问题吗？

增强C ++包装器

我用boost.python包装的代码示例如下：

//Required to address link errors in WIN32
#define BOOST_PYTHON_STATIC_LIB 

#include <libs/CppLib/LibraryFacade.h>
#include <libs/CppCudaPyModule/Converters/ListToVectorConverter.h>

#include <boost/python.hpp>
#include <boost/python/module.hpp>
#include <boost/python/def.hpp>
#include <boost/python/operators.hpp>

#include <vector>
#include <string>
#include <memory>

using namespace boost::python;

int execute(std::vector<std::string> const& args)
{
    LibraryFacade calculationEngine(args);
    return calculationEngine.execute();
}


void exportQbCppObjectsToPython()
{
    #The converter is not very important here
    #but I include them to give you a better picture 
    #of how the code looks like
    initialize_vector_converters<std::string>();

    class_<LibraryFacade>("LibraryFacade",init< std::vector<std::string> const& >())
        .def("execute", &LibraryFacade::execute)
    ;

}

BOOST_PYTHON_MODULE(CppCudaPyModule)        // Module name
{
    using namespace boost::python;

    exportQbCppObjectsToPython();

    def("execute", execute);
}
