我正在尝试构建一个使用 C 和 C++ 编写的第三方库 (GDAL) 的 go 项目。我遇到了这个错误:
In file included from contour.cpp:31:0:
cpl_port.h:187:6: error: #error Must have C++11 or newer.

一些搜索告诉我这是预期的,解决方法是简单地在编译器上设置一个标志(不相关,但仍然相关)。
我已经阅读了go 的构建文档,虽然它表明可以为单个编译器指定选项,但它没有明确说明如何,也没有提供任何示例。
我已经尝试了以下只是猜测,当 go build 命令接受它们时,它们会产生相同的错误,因此它们不起作用。
go build -gcflags -std=gnu++11 -ldflags -std=gnu++11
go build -gcflags -std=c++11 -ldflags -std=c++11
go build -gcflags -std=c++11
go build -gcflags -std=all=gnu++11 -ldflags -std=all=gnu++11
如何告诉 go 告诉 gcc 使用 C++11 或更高版本进行编译?
