试图链接我用MinGW构建的静态assimp库.以下是我得到的错误:

目标：

才能正确安装并libcurl C++使用CentOS 7。

电流输出：

libcurl当我使用命令编译程序时g++ somefile.cpp -lcurl -std=c++11 -o somefile，收到以下错误：

[user@localhost ~]$ somefile.cpp -lcurl -std=c++11 -o somefile
somefile.cpp:10:23: fatal error: curl/curl.h: No such file or directory
#include <curl/curl.h>
                       ^
compilation terminated.

细节：

libcurl是通过安装的sudo yum install libcurl（并且也尝试使用sudo yum install libcurl4-openssl-dev）。libcurl根据以前在 上安装的经验Ubuntu 20.04.1 LTS，如果我没记错的话，我通过将LD_LIBRARY_PATH指向 a解决了类似的问题libcurl.so object，如下所示，但这似乎对 没有影响CentOS 7。

[user@localhost ~]$ export LD_LIBRARY_PATH=/usr/local/lib/libcurl.so.4
[user@localhost ~]$ sudo ldconfig

如果我运行以下命令，我可以看到版本libcurl，这让我相信它已正确安装： …

我正在尝试使用visual studio 2015静态链接一个小的测试卷曲程序,但是我不能让它正确链接.

我使用这个批处理文件来编译成功运行的curl https://github.com/blackrosezy/build-libcurl-windows

然后我将libcurl目录复制到我的项目目录中,我的代码如下

 #include "stdafx.h"
 #include "libcurl/include/curl/curl.h"
 #pragma comment(lib, "libcurl/lib/static-debug-x64/libcurl_a_debug.lib")
 #define CURL_STATICLIB


 int main()
 {
    curl_global_init(CURL_GLOBAL_DEFAULT);
    CURL *curl = curl_easy_init();
    if (curl) {
        CURLcode res;
        curl_easy_setopt(curl, CURLOPT_URL, "http://google.com");
        res = curl_easy_perform(curl);
        curl_easy_cleanup(curl);
    }
    curl_global_cleanup();
    printf("Press any key to continue\n");
    getchar();
    return 0;
 }

但无论我做什么,我都无法让我的链接器成长:
