[QT] unable to open the containing file pcap.h (C1083) in QT creator

Problem description ：

When I try to winpcap Link to my QT In the creator project

Then introduce the #include <pcap.h> when , The code assistant will automatically fill

But when compiling, you get :

Error:C1083: Cannot open include file: 'pcap.h': No such file or directory

resolvent ：

stay C Create a new WpdPack Folder , And then Include and Lib Copy two folders into this folder .
In the project file .pro Add the following ：

INCLUDEPATH += C:/WpdPack/Include
LIBS += C:/WpdPack/Lib/wpcap.lib
LIBS += C:/WpdPack/Lib/Packet.lib
CONFIG += no_lflags_merge

explain ： Here the location of the folder can be freely selected , As long as the file path in the project file is consistent

Kit Download

• 1、 WinPcap Program , Install after decompression .

• 2、 WpdPack tool kit , After decompression, the folder contains Include and Lib Two subfolders .

Test code ：

#include <QCoreApplication>
#include <QDebug>
#define HAVE_REMOTE
#include <pcap.h>
#include <remote-ext.h>

int main(int argc, char *argv[])
{
    
    QCoreApplication a(argc, argv);

    pcap_if_t *alldevs;
    char errbuf[PCAP_ERRBUF_SIZE];

    /* Retrieve the device list from the local machine */
    if (pcap_findalldevs_ex(PCAP_SRC_IF_STRING, NULL /* auth is not needed */,
                            &alldevs, errbuf) == -1) {
    
        fprintf(stderr,"Error in pcap_findalldevs_ex: %s\\n", errbuf);
        exit(1);
    }

    /* Print the list */
    pcap_if_t *d;
    int i=0;
    for(d= alldevs; d != NULL; d= d->next) {
    
        printf("%d. %s", ++i, d->name);
        if (d->description) {
    
            printf(" (%s)\\n", d->description);
        } else {
    
            printf(" (No description available)\\n");
        }
    }

    if (i == 0) {
    
        printf("\\nNo interfaces found! Make sure WinPcap is installed.\\n");
    } else {
    
        /* We don‘t need any more the device list. Free it */
        pcap_freealldevs(alldevs);
    }

    return a.exec();
}
