Curl_easy_getinfo符号错误

我使用星号13.5.0版本。在utils目录中，我创建了一个名为curl_util的新模块，其源代码如下:

#include "asterisk/curl_utils.h"
HttpResponse * httpResponseNew()
{
    HttpResponse * response = calloc(1, sizeof(HttpResponse));
    return response;
error:
    return NULL;
}
HttpResponse * httpRequestPost(char *url, char *post_body, size_t size)
{
    struct MemoryStruct chunk;
    CURL *curl = curl_easy_init();
    chunk.memory = malloc(1);
    chunk.size = 0;
    HttpResponse *response = httpResponseNew();
    curl_easy_setopt(curl, CURLOPT_URL, url);
    curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0);
    curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0);
    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 0);
    curl_easy_setopt(curl, CURLOPT_POST, 1L);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, post_body);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, size);
    curl_easy_setopt(curl, CURLOPT_TIMEOUT, 30);
    curl_easy_setopt(curl, CURLOPT_NOSIGNAL, 1);
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, HttpResponseMemoryWriter);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, (void *)&chunk);
    response->res = curl_easy_perform(curl);
    if (response->res != CURLE_OK)
    {
        response->OK = 0;
    }
    else
    {
        response->OK = 1;
        response->size = chunk.size;
        response->body = chunk.memory;
    }
    curl_easy_cleanup(curl);
    return response;
error:
    free(chunk.memory);
    if (curl) curl_easy_cleanup(curl);
    return response;
}

在chan_sip.c中，我调用上面提到的httpRequestPost函数。执行make和make install是可以的。但是，当启动dahdi和星号时，我得到了以下错误:

加载模块chan_sip错误。http prequestpost

loader.c: module chan_sip. c因此无法加载

你能给点提示或建议来修复这个错误吗?
