I'm creating my own ARP eader with below shown code, however this code ain't working, I get error message as ‘struct arphdr’ has no member named ‘ar_sha’, ar_spa, ar_tha, ar_tpa. I've checked net/if_arp.h, these members are part of struct arphdr. Why i'm unable to use them?? Please assist.
arp.ar_hrd=htons(ARPHRD_ETHER);
arp.ar_pro=htons(ETHERTYPE_IP);
arp.ar_hln=6;
arp.ar_pln=4;
arp.ar_op=htons(ARPOP_REQUEST);
arp.ar_sha=ether_aton("ss:ss:ss:ss:ss:ss");
arp.ar_spa=inet_addr("192:168:32:128");
arp.ar_tha=ether_aton("ff:ff:ff:ff:ff:ff");
arp.arp_tpa=inet_addr("192.168.32.1");

I'm trying to access a known object and get one of its properties as a Number
Unfortunately, the following code...
Isolate *isolate = args.GetIsolate();
Local<Object> opts = args[0]->ToObject();
Local<Number> mode = opts->Get(String::NewFromUtf8(isolate, "mode"))->ToNumber();
is giving the following warning:
warning C4996: 'v8::Value::ToNumber': was declared deprecated
....node-gyp\8.5.0\include\node\v8.h(9578): note: see declaration of 'v8::Value::ToNumber'
In the v8.h I noticed the comment on ToNumber: "Use maybe version". I've attempted to convert it to a Maybe but I've not yet been able to get any attempt to compile correctly. What is the correct approach to using Maybe and getting the Number object?
Looks like the "Use maybe version" comment in the v8.h led me in the wrong direction. The deprecate notice seems to apply to the method-overload that is missing the isolate. If you pass the isolate...
->ToNumber(isolate);
it works without warning.
I am trying to write my own implementation of REST server using C++ REST SDK.
the class used is http_listener.
Almost all of it compiles properly but when i try to buld a URI using class web::http::URI it gives me error, also if pass the URI to http_listener class it giving error.
below us the code that gives error.
void CPPRESTSERVER::Start()
{
//building the URI//
utility::string_t address = "http://";
address.append(m_IP);
address.append(":");
address.append(std::to_string(m_port));
address.append("/");
m_Uri(U(address)); //m_Uri class member of type web::http::uri
//m_CustUri(m_Uri);
//m_CustUri.append_path(m_pathIP);
//m_CustUri.set_port(m_port);
//*******************
m_rstServer(U(m_Uri.to_string())); //m_rstserver class member of type http_listener
m_rstServer.support(web::http::methods::GET, std::bind(&CPPRESTSERVER::handle_GET, this, std::placeholders::_1));
}
i have tried the below
1) m_Uri(U(address)); also as m_Uri(address); but still giving errors.
2) m_rstServer(U(m_Uri.to_string())); also as m_rstServer(m_Uri.to_string()); also as m_rstServer(m_Uri); also as m_rstServer(U(m_Uri));
but still they give errors eventhough they have respective cusntructors of functions accepting argumets of required type
CPPRESTSERVER.cpp:57:21: error: no match for call to ‘(web::uri) (utility::string_t&)’
m_Uri(U(address));
^
CPPRESTSERVER.cpp:62:25: error: no match for call to ‘(web::http::experimental::listener::http_listener) (web::uri&)’
m_rstServer(U(m_Uri.to_string()));
any suggestions?????? i have stuck due these two errors. also i am compiling in ubuntu with C++11 standard.
i am receiving an error while editing extensions in opencart.
Fatal error: Call to a member function link() on a non-object in C:\xampp\htdocs\organics2you\admin\controller\module\couponpop.php on line 28
this problem because the different version just creat variable and pass object of url as $data['url']=$this->url; and call it from your temp;
Whenever I compile my C++ code using make, I always get warning as -
/client/main.cc: In function âvoid print_rows(cql::cql_result_t&)â:
/client/main.cc:41:5: warning: label âstdâ defined but not used [-Wunused-label]
Somehow I always see â appended in my print_rows method and std as well.. But whenever I go on vi editor, I never see â appeneded..
Is there anything I am missing? How to fix this problem?
I get confused when I get errors like these
I have
FxSmartPtr<FxStreamable> able(FcNew,stream->StreamInObject());
FxGlobalPair pair(id,able);
I get an error on FxGlobalPair pair(id,able); that is able is not a type.
I tried modifying to
FxGlobalPair pair(id,FxSmartPtr<FxStreamable>::able);
but I get an error that is error: 'class FxSmartPtr<FxStreamable>::able' has not been declared
What concept am I missing?
UPDATE: typedef pair<FxID, FxSmartPtr<FxStreamable> > FxGlobalPair;
UPDATE 2:
Heading
I think that you have found the Most Vexing parse
The problem is that
FxSmartPtr able(FcNew,stream->StreamInObject());
may define a function named able, instead of a variable.
