如何解决错误“未定义对‘pcap_parse’的引用”
我正在尝试在 C++ 程序中使用 libpcap 库。
我已经下载了libpcap-1.0.0.tgz，解压了它，然后
./configer
make
make install
我有了libpcap.a和headers，并且我有编写了一个示例程序来测试它。但它给了我编译器错误，如下所示：
/usr/local/lib/libpcap.a(gencode.o): In function `.L151':
gencode.c:(.text+0x7f4): undefined reference to `pcap_parse'
collect2: ld returned 1 exit status
我正在使用以下命令编译该程序：
g++ -o test test.cpp -lpcap
我在构建 libpcap 和 headers 时做错了什么吗？
I am trying to use the libpcap library in a C++ program.
I have downloaded libpcap-1.0.0.tgz, untared it, and then
./configer
make
make install
I have libpcap.a and headers with me, and I have written one sample program to test it. But it is giving me compiler errors as follows:
/usr/local/lib/libpcap.a(gencode.o): In function `.L151':
gencode.c:(.text+0x7f4): undefined reference to `pcap_parse'
collect2: ld returned 1 exit status
I am compiling this program using following command:
g++ -o test test.cpp -lpcap
Am i doing anything wrong in building libpcap and headers?

我很确定您需要在
test.cpp之前传递-lpcapI'm pretty sure you need to pass
-lpcapbeforetest.cpp尝试安装 libstdc++-4.8-dev - 当我遇到类似问题时，这对我有用。
Try installing libstdc++-4.8-dev - this worked for me when I had a similar issue.
你必须使用此命令安装 Libpcap-devel ( sudo apt-get install libpcap-dev ) 如果它不起作用也安装 flex (sudo apt-get install bison )
祝你好运
You have to install Libpcap-devel using this command ( sudo apt-get install libpcap-dev ) if it doesn't work install flex too (sudo apt-get install bison)
good luck
包含在运行 ./configure 和 make 后生成的 Grammar.c。
Include grammar.c which gets generated after you run ./configure and make.
