Hi,
Same on centos8 with latest crow_all.hpp (ninja error):

source:

#include "include/crow_all.h"

int main()
{
    crow::SimpleApp _app;
    CROW_ROUTE(_app, "/")( []() {
        return "Hello World";
    });
    _app.port(80).multithreaded().run();
}

meson.build:

project('crow_tuto', 'cpp')

cxx = meson.get_compiler('cpp')

boost = dependency('boost',version : '>=1.73.0', required : false)
if not boost.found()
  boost_inc = include_directories('boost/', is_system:true)
  boost  = declare_dependency(include_directories : boost_inc)
endif
executable('hello_world', 'hello_world.cpp', dependencies : boost)

Regards,
..Francine

@frsauvage This version of crow is incompatible with boost 1.70 or later, you'll need to use a lower version.

If you'd like a version compatible with 1.70 or later, take a look at this.

Note: regarding the meson.build, the boost dependency is absolutely required, crow will not run without boost. I'm not sure how meson works but I thought I should point it out.

Hi @The-EDev, thanks,
That's the point. I didn't notice that incompatibility before.
I should use a lower version,

@frsauvage You can change socket_adaptors.hpp

#if BOOST_VERSION >= 107000
#define GET_IO_SERVICE(s) ((boost::asio::io_context&)(s).get_executor().context())
#else
#define GET_IO_SERVICE(s) ((s)->get_io_service())
#endif

and

	boost::asio::io_service& get_io_service() {
	  return GET_IO_SERVICE(socket_);
	}
......
	boost::asio::io_service& get_io_service() {
	  return GET_IO_SERVICE(raw_socket());
	}

@The-EDev
It worked. Thank you very much!
For clarification, here is what I did in order to get the helloworld example to build and run properly:

$ git clone [email protected]:CrowCpp/Crow.git
$ cd Crow && mkdir build && cd build
$ cmake ..
$ make
$ cd examples/
$ ./helloworld
Open up a new browser window/tab. In the address bar type:  http://0.0.0.0:18080
Hit ENTER

You should see a plain text html 'Hello World' in the browser window.

If you are running this on Ubuntu 20-or-higher ( I'm running on Ubuntu 20.04),
make sure that you already have these dependencies before building/running:
sudo apt-get install build-essential libboost-dev libboost-system-dev libasio-dev
sudo apt install libboost-system1.71-dev # OR WHICHEVER one is the latest version
