c++ - [Dev C++]用curl库编译程序的问题

Question

您好，我想使用带有 MinGW64 编译器的 DevCpp 编译 Windows .EXE 应用程序。我要编译的应用程序非常简单，需要 CURL 库。我正在使用 Windows 8 64 位，Orwell Dev-C++ V 5.3.0.4。我已经从官方网站 (Win64 - MinGW64 devel v.28.1) 下载了 CURL 库。我已将所有 include、bin 和 lib 文件复制到 MinGW64 文件夹，但程序无法编译，因为它出现以下链接器错误:

            [Linker error] C:\Users\Panos\AppData\Local\Temp\ccSFo7Pn.o:upload.cpp:(.text+0x37): undefined reference to `__imp_curl_global_init'
        [Linker error] C:\Users\Panos\AppData\Local\Temp\ccSFo7Pn.o:upload.cpp:(.text+0x74): undefined reference to `__imp_curl_formadd'
        [Linker error] C:\Users\Panos\AppData\Local\Temp\ccSFo7Pn.o:upload.cpp:(.text+0xb1): undefined reference to `__imp_curl_formadd'
        [Linker error] C:\Users\Panos\AppData\Local\Temp\ccSFo7Pn.o:upload.cpp:(.text+0xba): undefined reference to `__imp_curl_easy_init'

        [Linker error] C:\Users\Panos\AppData\Local\Temp\ccSFo7Pn.o:upload.cpp:(.text+0x1dc): undefined reference to `__imp_curl_formfree'
        [Linker error] C:\Users\Panos\AppData\Local\Temp\ccSFo7Pn.o:upload.cpp:(.text+0x1ec): undefined reference to `__imp_curl_slist_free_all'
        collect2: ld returned 1 exit status

我唯一成功编译程序的方法是使用编译器的 -DCURL_STATICLIB -c -h -Icurl\include 选项，但我得到的只是一个无法在我的操作系统中运行的 16 位应用程序!

我试图编译的代码是这个 CURL 示例: http://curl.haxx.se/libcurl/c/postit2.html

我花了很多时间在互联网上搜索和阅读指南来编译我的程序，但没有任何运气。请帮助我并告诉我我做错了什么!

谢谢!

如果它在您尝试运行已编译的二进制文件时要求 libcurl.dll，则它在运行时需要 libcurl.dll。尝试将 libcurl.dll 放入二进制文件的工作目录中。
