最近，由于多种原因，我将Windows从GCC切换到了Clang，我想在一个简单的程序中使用libcurl，但是我觉得没有关于如何为此设置Clang的指南。 我用
clang++ -static -DCURL_STATICLIB curl-7.64.1-win64-mingw/lib/libcurl.a http-post.cpp -std=c++17 -g -Xclang -flto-visibility-public-std -o trading.exe
在VSCode中，我什至不想使用Make或CMake，因为它是简单的程序。
使用该命令，我得到：

如何正确设置构建命令？ 我可以使用比
更整洁的东西吗-std=c++17 -Xclang -flto-visibility-public-std
使用最新的C ++和STL功能吗？
编辑：根据https://github.com/Microsoft/vcpkg/issues/2621，我需要Ws2_32.Lib，Wldap32.Lib和Crypt32.Lib之类的东西，我对此有所考虑，但是由于我觉得Clang在某种程度上是跨平台的，所以我认为具有自己的二进制文件功能，并且链接这些Windows库并不是很整齐...
EDIT2：尤其是当我链接libcurl时。 a ，而不是.lib。
EDIT3：仍然缺少strdup，即POSIX，所以我不确定是否应该使用链接标志或包含具有该功能定义的文件等...
答案 0 :(得分：-1)
选项-static意味着产生一个静态库。您显然正在生成一个可执行文件。只需删除该选项，就可以了。同样，您可能必须将cpp文件放在libcurl之前才能满足链接要求。
编辑：我的错。当-static选项同时找到静态和共享时，gcc的{{1}}选项使其更喜欢使用静态库。在这里，您将显式链接到静态库。仍然不需要-l选项。
为我服务，是因为它不读取完整的输出。您缺少许多其他依赖项，例如WinSock，C运行时，zlib，ssl。
