#23 Why does my CppCMS application not run with FastCGI configuration?

[fi la]

I follow this tutorial to create my sample application CMS00 on my Ubuntu machine. This is added to the NginX server block of /etc/nginx/sites-available/default:

location ~ ^/CMS00.*$ {
    fastcgi_pass    127.0.0.1:8080;
    fastcgi_split_path_info ^(/CMS00)((?:/.*))?$;  
    fastcgi_param   PATH_INFO       $fastcgi_path_info;  
    include         fastcgi_params;
}

Then I use this config.js file:

{  
  "service" : {  
    "api" : "fastcgi",
    "ip": "127.0.0.1",
    "port" : 8080
  }  
}

And then added the path with:

export LD_LIBRARY_PATH=/usr/local/lib

When I try to run it:

./CMS00 -c config.js

Nothing comes on. However if I change config.js to:

{  
    "service" :
    {  
        "api" : "http",  
        "port" : 8080  
    },  
    "http" :
    {  
        "script_names" : [ "/CMS00" ]  
    }  
}

It runs properly. Could someone tell me what I did wrong with the FastCGI configuration? Thank you so much.
