在Windows上安装MAPNIK，提供C＆＃x2B;＆＃x2B; 14标准问题，clang或g＆＃x2b;＆＃x2B;

Question

我遵循了

我有第14版。但是，当我尝试在Windows上安装Mapnik时，它说：“ C ++编译器不支持C ++ 14标准（-std = C ++ 14），这是必需的。请升级您的编译器

” ./configure cxx = clang ++ -14 cc = clang-14

scons：读取sconscript文件...

欢迎使用mapnik ...

在释放模式下在Windows上配置...

检查pkg-config ...没有

检查freetype-config ...没有

检查dlfcn.h支持...否

检查编译器（clang ++ -14）是否支持-STD = C ++ 14标志...（加速）NO

C ++编译器不支持C ++ 14标准（-std = C ++ 14），这是必需的。请升级您的编译器

config.log内容为：

如果您看到config.log，则说“'clang ++ -14'不被识别为内部或外部命令”，

为什么它试图使用版本名称运行该命令？如果不是这样，那么我应该如何将版本传递给./configure命令？

我也尝试了G ++（版本6.3.0），并遇到了类似的问题。我以前的叮当声是Visual Studio随附的版本12。当我仅运行./configure时，配置日志说：

当Clang V12不起作用时，我安装了LLVM + Clang V14。我还尝试了首先导出变量，例如导出cxx =“ clang ++ -14”和导出cc =“ clang-14”。但是没有运气... 请提供帮助，因为在过去的两天中，我很严重陷入困境... 谢谢
