Description

The generated CPPRestSDK client for the sample Pet Store does not compile in Visual Studio 2017 (CMake generated Visual Studio solution), with the following error:

2>...\samples\client\petstore\cpp-restsdk\client\ModelBase.cpp(239): error C2664: 'void org::openapitools::client::model::HttpContent::setData(std::shared_ptrstd::istream)': cannot convert argument 1 from 'std::shared_ptr < utility::stringstream_t >' to 'std::shared_ptr < std::istream >' 2>...\samples\client\petstore\cpp-restsdk\client\ModelBase.cpp(239): note: No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

When using the CPPRestSDK library for Windows, in its basic_types.h the type utility::stringstream_t is always defined as an alias for std::wstringstream. However, the generated HttpContent::setData method always takes a std::shared_ptr < std::istream > as parameter, not a std::shared_ptr < std::wistream >

I need help with this. It's a blocker for any CPPRestSDK generated API client for Windows.

openapi-generator version

The client API is already generated in the openapi-generator repository.

OpenAPI declaration file content or url

The client API is already generated in the openapi-generator repository.

Command line used for generation

N/A

Steps to reproduce

Install CPPRestSDK with vcpck, as described in CPPRestSDK Modify the local CMakeLists.txt file for compilation with vcpkg, as described in the file contents. Generate the Visual Studio solution with 'cmake -G "Visual Studio 15 2017" < path of the CMakeLists.txt file > ' or 'cmake -G "Visual Studio 15 2017 Win64" < path of the CMakeLists.txt file > ' Open the generated solution and compile
