Question

我在windows 10上安装了cygwin64，还安装了g ++和libCurl库。当我运行代码时，g ++编译器抛出了这个错误'#error仅支持Win32目标！'。

我如何解决这个错误？我是否要安装其他版本或库？

TestCurl.cpp

#include <iostream>
#include <string>

#include <curl/curl.h>

static size_t WriteCallback(void *contents, size_t size, size_t nmemb, void *userp)
{
    ((std::string*)userp)->append((char*)contents, size * nmemb);
    return size * nmemb;
}

int main(void)
{
  CURL *curl;
  CURLcode res;
  std::string readBuffer;

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://www.google.com");
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, &readBuffer);
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);

    std::cout << readBuffer << std::endl;
  }
  return 0;
}

生成文件

CC=g++
MIN_GW = C:\cygwin64\usr\x86_64-w64-mingw32\sys-root\mingw\include

all: call.o

call.o: call.cpp
    $(CC) call.cpp -o call -I$(MIN_GW)
