Error compiling sio_client_impl.cpp

[GIP2000]

I am trying to compile the project however I run into an issue when I compile the sio_clinet_impl.cpp file

Makefile `.PHONY: clean all: SocketHandler.out

clean: rm -rf SocketHandler.out rm -rf sio_client.o rm -rf sio_socket.o rm -rf sio_packet.o rm -rf SocketHandler.o`

my boost version is 1.71.0ubuntu2 (I ran dpkg -s libboost-dev | grep 'Version')

I moved the contents of the src folder to the main directory but left everything else in the folder that comes with the git clone. I am clearly doing something wrong can anyone help me please.

I get these errors: ` internal/sio_client_impl.cpp: In member function ‘asio::io_service& sio::client_impl::get_io_service()’: internal/sio_client_impl.cpp:201:39: error: invalid initialization of reference of type ‘asio::io_service&’ {aka ‘asio::io_context&’} from expression of type ‘boost::asio::io_service’ {aka ‘boost::asio::io_context’} 201 | return m_client.get_io_service(); | ~~~~~~~~~~~~~~~~~~~~~~~^~ internal/sio_client_impl.cpp: In member function ‘void sio::client_impl::ping(const error_code&)’: internal/sio_client_impl.cpp:321:88: error: no matching function for call to ‘asio::basic_waitable_timerstd::chrono::_V2::steady_clock::basic_waitable_timer(boost::asio::io_service&)’ 321 | _timer.reset(new asio::steady_timer(m_client.get_io_service())); | ^

@GIP2000 i get same issue if you solved please share for me

[Amith4504]

I have been encountering the same issue . Has anyone resolved the errors ?

[megan1997s]

I have the same issue boost is still "required" even though it should not be and I eliminated most of the errors by including boost to the project and have it down to for errors

[jmigual]

Hi, as of af68bf3067ab45dc6a53261284e0da9afd21b636 Boost is no longer required. We've updated the installation instructions without CMake. Can you try following them and see if the issue persists?

[jimver04]

When you say without CMake, I have inferred that you mean Visual Studio, but which version? For the sake of user friendliness say at least Visual Studio. There are also other C++ IDEs. Thanks!

[jmigual]

Hi @jimver04. We don't mean any IDE in particular. Each IDE or build system has a way of specifying a header search path (point 2) a source files path (point 3) and some defines (point 4). So in your IDE or build system you need to specify:

• That the header search paths should contain:
  • ./lib/asio/asio/include
  • ./lib/websocketpp
  • ./lib/rapidjson/include
• That the files to be built from socket.io-cpp are all files under the ./src directory
• That the defines that must be set are:
  • BOOST_DATE_TIME_NO_LIB
  • BOOST_REGEX_NO_LIB
  • ASIO_STANDALONE
  • _WEBSOCKETPP_CPP11_STL_
  • _WEBSOCKETPP_CPP11_FUNCTIONAL_

Afterwards you can use the socket io c++ library by including the header sio_client.h in your code.

[jimver04]

I have done these steps and I get:

cannot open file 'boost.lib'

boost.lib is nowhere in my filesystem

[jmigual]

Boost is not required. We only officially support CMake and provide info for other build systems. I don't know how to help you if you are not using CMake

[jimver04]

ok, I had to remove boost.lib from Linker/Additional Dependencies. boost.lib is needed only for the QT example I guess ... Probably it was forgotten if QT example was used as a start base for the Console example.

[jmigual]

Ah you are right! We forgot to remove that part from the examples. I'll remove it from the documentation
