/Mingw32/bin/ld.exe: cannot find -llibcurl?

我正在尝试为我的项目编译 Libcurl，但我得到以下错误。

g++ -g -o Main.exe Main.o I"C:TestsrcWebSocketcurl" L"C:TestsrcWebSocketlib" -D_WIN32_WINNT=0x0601 -DWINVER=0x0601 -DCURL_STATICLIB -llibcurl 
/mingw32/bin/ld.exe: cannot find -llibcurl

当我使用 mingw32 构建 libcurl 时，我得到了两个文件，即 libcurl.a、libcurl.la。我在 c：\Test\src\websocket\lib 下添加了这两个文件。此外，所有必需的标头都在 C：\Test\src\WebSocket\curl 下我不确定为什么链接器无法链接这些库。

我尝试过的：

最初我收到这样的错误：

main.cpp:11: undefined reference to __imp__curl_easy_init'
main.cpp:13: undefined reference to __imp__curl_easy_setopt'
main.cpp:14: undefined reference to __imp__curl_easy_perform'
main.cpp:17: undefined reference to __imp__curl_easy_cleanup'

在发布SO帖子后，我意识到我忘记了链接我的libcurl库，如下所示：

WS_DIR = "C:TestsrcWebSocketcurl"
WS_LIB = "C:TestsrcWebSocketlib"
g++ -c -std=c++11 -g -fpermissive src/Main.cpp -I${WS_DIR} -L${WS_LIB}  -D_WIN32_WINNT=0x0601 -DWINVER=0x0601 -DCURL_STATICLIB -llibcurl

但现在我面临链接问题。

任何具有良好编译器和 libcurl 理解的人都可以为此提供帮助吗？

@Jaochim ：多亏了你，我更改了我的制作文件。但是现在我面临以下错误：
