I'm compiling with gcc 7.3.0 on Ubuntu 18.04

I'm using the latest master branch of websocketpp
and standalone asio from here https://github.com/chriskohlhoff/asio/tree/84e9a48ae6ff040311dfdd9bd4b8e761832509fd

I'm not sure if you can fix this or it's an issue with asio but I want to let you know about this.

Here's my code:
example0.cpp

#define ASIO_STANDALONE
#include <websocketpp/config/asio_client.hpp>

int main() {
	return 0;
}

CMakeList.txt

cmake_minimum_required (VERSION 3.6)
project(example)

add_executable(hello-example
	example0.cpp
)

target_include_directories(hello-example PUBLIC /home/hao-qi/Documents/repositories/sleepy-discord-private/deps/asio/asio/include/)
target_include_directories(hello-example PUBLIC /home/hao-qi/Documents/repositories/sleepy-discord-private/deps/websocketpp/)
find_package(Threads REQUIRED)
target_link_libraries(hello-example PUBLIC ssl crypto Threads::Threads)

Here's the Errors:

websocketpp relies on deprecated features of asio which have been removed in the latest commits: chriskohlhoff/asio@9801132

1.12.2 would be the last version supported by websocketpp as it currently is.

At least some of these errors are due to this line:

https://github.com/zaphoyd/websocketpp/blob/master/websocketpp/transport/asio/security/none.hpp#L172

where websocketpp is passing a constructor argument through make_shared in a reference_wrapper. This shouldn't be required as make_shared will perfectly forward its arguments.

(N.B. this is a problem because what in asio was previously a non-template constructor that took io_context& is now a SFINAE-d template constructor, and the deduced ExecutionContext template argument reference_wrapper<io_context> seems to satisfy the SFINAE check but does not satisfy the needs of the function implementation.)

chriskohlhoff referenced this issue in boostorg/asio Mar 7, 2019
@chriskohlhoff
Add custom I/O executor support to I/O objects.
59066d8 
All I/O objects now have an additional Executor template parameter. This
template parameter defaults to the asio::executor type (the polymorphic
executor wrapper) but can be used to specify a user-defined executor
type.

I/O objects' constructors and functions that previously took an
asio::io_context& now accept either an Executor or a reference to a
concrete ExecutionContext (such as asio::io_context or
asio::thread_pool).

One potential point of breakage in existing user code is when reusing an
I/O object's io_context for constructing another I/O object, as in:

    asio::steady_timer my_timer(my_socket.get_executor().context());

To fix this, either construct the second I/O object using the first I/O
object's executor:

    asio::steady_timer my_timer(my_socket.get_executor());

or otherwise explicitly pass the io_context:

    asio::steady_timer my_timer(my_io_context);

as @chriskohlhoff suggested removing the wrapper lib::ref on asio calls seems to do the trick.
Thing is lib::refwrapper (for c++03 compilers??) is used somewhere else in code, quite a few times, so I guess we need to leave those alone unless we are talking to asio.

I have a fork here that just does that, but I'm not confident/expert on websocketpp to ask a pull request as I think there's more to it, and I couldn't have tested on many configs/systems. Anyway this is the fork:

https://github.com/ziocleto/websocketpp

Also @stefan-floeren I do not understand your PR as you've just replaced lib::make_shared with naked new, so that will be memory leaks midnight feast all over the places, surely?

@stefan-floeren

The lib::ref wrapper is still required for C++03 compilers. As long as they are supported we unfortunately cannot get rid of them. If @zaphoyd decides to drop support, removing those calls would be the easiest solution. Otherwise, we need to stick to a different solution.

@ziocleto I replaced assignments and make_shared with shared_ptr::reset and new. Both boost::shared_ptr and std::shared_ptr take ownership and make sure to not leak memory even in case of exceptions. The only difference between the make_shared and the reset option lies in the memory layout, as reset contains an additional level of indirection.

@ziocleto
Copy link

@stefan-floeren ah I see, so you've used .reset(newto keep 03 compatibility I guess, well if that's memory leak proof then I think we should reach out to @zaphoyd and make your PR accepted.

Do you mean I should dowload boost with version 1.12.0? And I don't find boost package in 1.12, now there are only 1.20.0 version the most olds ,

@stefan-floeren

No, 1.12.2 is the Asio version. The last working Boost is 1.69.

Just FYI, airdcpp-webclient builds fine when using "develop" branch of websocketpp (with boost 1.71). It fails when using the last released version.
