c++ - 使用 liboauth 时出现链接错误。获取错误 undefined reference to `oauth_url_escape'

Question

我在使用 liboauth 时遇到链接错误 代码编号

 #include <cstdlib>
    #include<oauth.h>
    using namespace std;

    /*
     * 
     */
    int main(int argc, char** argv) {
        oauth_url_escape("vivek");
        return 0;
    }

Makefile 是由 Netbeans 自动生成的

CP=cp
GREP=grep
NM=nm

RANLIB=ranlib
CC=gcc

我们只需要改变C++代码中的include语句

extern "C" {
#include <oauth.h>
 }
