[Cppcms-users] Very strong problems when running the CppCms project

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Good evening, dear friends!
I really love the CppCms framework, because it gives controllability, power and speed. I have an error in the project:
"No configuration defined"

I can not yet run the minimal project on CppCms. Can you help? I'm using Nginx 1.10.3. I configured the nginx.conf configuration file like this:
user yurkosan;
worker_processes 12;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
events {
worker_connections 768;
}
http {
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log notice;
gzip on;
gzip_disable "msie6";
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
server {
# Нужно вручную создать переменую PATH_INFO 
# используя перезапись URL 
set $path_info ""; 
if ( $fastcgi_script_name ~ ^/hello(.*)$ ) { 
set $path_info $1; 
}
# Указываем URL для совпадения 
location ~ ^/hello.*$ { 
# Сокет для обмена данными 
fastcgi_pass unix:/tmp/hello-fcgi-socket;
# Все поддерживаемые переменные CGI 
fastcgi_param QUERY_STRING $query_string; 
fastcgi_param REQUEST_METHOD $request_method; 
fastcgi_param CONTENT_TYPE $content_type; 
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME /hello; 
fastcgi_param PATH_INFO $path_info; 
fastcgi_param REQUEST_URI $request_uri; 
fastcgi_param DOCUMENT_URI $document_uri; 
fastcgi_param DOCUMENT_ROOT $document_root; 
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param GATEWAY_INTERFACE CGI/1.1; 
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param REMOTE_ADDR $remote_addr; 
fastcgi_param REMOTE_PORT $remote_port; 
fastcgi_param SERVER_ADDR $server_addr; 
fastcgi_param SERVER_PORT $server_port; 
fastcgi_param SERVER_NAME $server_name; 
} 
} 
}

I use this project configuration file (config.json):
{
"service" : {
"api" : "fastcgi",
"socket" : "/tmp/hello-fcgi-socket"
}
}

I use the environment of Qt Creator 4.5.0 (Qt 5.9.2).
I'm using the following project file (kinomusorka_ru.pro):

LIBS += -L/usr/local/lib/ -lbooster -lcppcms
INCLUDEPATH += /usr/local/include
DEPENDPATH += /usr/local/include
TEMPLATE = app
CONFIG += console c++14
CONFIG -= app_bundle
CONFIG -= qt
SOURCES += main.cpp
I use the following source code (main.cpp):

#include <cppcms/application.h>
#include <cppcms/applications_pool.h>
#include <cppcms/service.h>
#include <cppcms/http_response.h>
#include <iostream>
class my_hello_world : public cppcms::application {
public:
my_hello_world(cppcms::service &srv) :
cppcms::application(srv)
{
}
virtual void main(std::string url);
};
void my_hello_world::main(std::string /*url*/)
{
response().out()<<
"<html>\n"
"<body>\n"
" <h1>Hello World</h1>\n"
"</body>\n"
"</html>\n";
}
int main(int argc,char ** argv)
{
try {
cppcms::service srv(argc,argv);
srv.applications_pool().mount(cppcms::applications_factory<my_hello_world>());
srv.run();
}
catch(std::exception const &e) {
std::cerr<<e.what()<<std::endl;
}
}
// vim: tabstop=4 expandtab shiftwidth=4 softtabstop=4

The project configuration file is in the folder /home/yurkosan/www/domains/kinomusorka.ru/debug.
In the same folder is the assembly of binary files. As a result, I get an error
"No configuration defined".
The project does not start. Tell me, what do I need to do to run the minimal project on the framework?
Can you give a ready-made example for a nginx server and Qt Creator?

With deep respect. Yuri. Novosibirsk.
