Error C2664 building with VS 2013

I tried to compile with VS 2013 and I get these errors :

I tried with Boost 1.55, it compiles, but not with Boost 1.58

[HouseHo]

Did you find a solution to compile pion with boost 1.59 at the end? (in VS2013/2015)

[snikulov]

@HouseHo Not sure that it requires any solution.
I've just successfully built master branch with Boost 1.62 on Windows 10/Visual Studio 2015 64 bit/CMake 3.8.0-rc4
What exactly the issue you've observed?

[HouseHo]

@snikulov Privet, I was compiling in the following environment

• VS2015
• Boost 1.59
• pion 5.0.6 32b release (static)

Both tcp_server.cpp and http_server.cpp give C2664.
For instance server::handle_connection() has a call to boost::bind() where a parameter has casting problem.

void server::handle_connection(tcp::connection_ptr& tcp_conn)
{
    request_reader_ptr my_reader_ptr;
    my_reader_ptr = request_reader::create(tcp_conn, boost::bind(&server::handle_request,
                                           this, _1, _2, _3));
    my_reader_ptr->set_max_content_length(m_max_content_length);
    my_reader_ptr->receive();
}

This gives

Severity Code Description Project File Line Error C2664 'void boost::_mfi::mf3<void,pion::http::server,pion::http::request_ptr &,pion::tcp::connection_ptr &,const boost::system::error_code &>::operator ()(T *,A1,A2,A3) const': cannot convert argument 2 from 'const pion::http::request_ptr' to 'boost::shared_ptr<pion::http::request> &' pion C:\app\boost-1.59.0\boost\bind\bind.hpp 459

Other related code of interested.

    //request_reader.hpp
    static inline boost::shared_ptr<request_reader>
        create(tcp::connection_ptr& tcp_conn, finished_handler_t handler){...}

        tcp::connection_ptr& tcp_conn, const boost::system::error_code& ec){...}

    }

[snikulov]

@HouseHo Have you used CMake?

[HouseHo]

No, I didn't use cmake... I'm in the process to migrate a legacy solution from VS2008 to VS2015, where pion is added as a project inside the VS build.

Is cmake the only way to go?

Thanks for the quick response :D

[snikulov]

Try build it using CMake

git clone https://github.com/splunk/pion.git
cd pion/build
cmake .. -G"Visual Studio 14 Win64" -DBOOST_ROOT= < path to boost root >
cmake --build . --config Release

[HouseHo]

Tried first on my old version of pion 5.0.6, I reached the same problem.

C:\_path\boost-1.59.0\boost/bind/bind.hpp(315): error C2664: 'void boost::_mfi::mf1<void,pion::tcp::server,pion::tcp::c onnection_ptr &>::operator ()(T *,A1) const': cannot convert argument 2 from 'const boost::shared_ptr<T>' to 'boost::sh ared_ptr<T> &' [E:\Users\myName\_del_pion-5.0.6\build\src\pion.vcxproj]

Then trying with the head git checkout, but there seems to be a problem with cmake 3.8.0-rc4.
A mention of cmake_policy new vs old.

CMake Warning (dev) at cmake/PionUtils.cmake:42 (if):
  Policy CMP0054 is not set: Only interpret if() arguments as variables or
  keywords when unquoted.  Run "cmake --help-policy CMP0054" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  Quoted variables like "MSVC" will no longer be dereferenced when the policy
  is set to NEW.  Since the policy is not set the OLD behavior will be used.
Call Stack (most recent call first):
  CMakeLists.txt:30 (pion_update_compilation_opts)
This warning is for project developers.  Use -Wno-dev to suppress it.

Clarification:

• I'm still at boost 1.59 <- I'll update this to 1.62 as you originally suggested.
• I'm compiling with

cmake .. -G"Visual Studio 14 2015" -DBOOST_ROOT=C:/_path/boost-1.59.0/stage/lib/win32 -DOPENSSL_ROOT_DIR=E:/_path/OpenSSL-1.0.2d -DZLIB_INCLUDE_DIR=E:/_path/zlib-1.2.11/include -DZLIB_LIBRARY=E:/_path/zlib-1.2.11/lib/win32/ZlibStatRelease/zlibstat.lib -DZLIB_ROOT=E:/_path/zlib-1.2.11 -DLOG4CPLUS_ROOT=E:/_path/log4cplus
cmake --build . --config Release

[snikulov]

@HouseHo Could you please try master branch? I suspect this issue was fixed here 6425c64

[HouseHo]

Update:
The main branch works with VS2015/boost 1.59.
And I see the solution to the C2664 for my old version of pion, basically a dozen of method and functions need to have their parameters declared as const as in the head branch.

Thanks for the support.
