从我在FAQ中读到的内容来看，你还不能确定:

Do Go programs link with C/C++ programs? There are two Go compiler implementations, gc (the 6g program and friends) and gccgo. Gc uses a different calling convention and linker and can therefore only be linked with C programs using the same convention. There is such a C compiler but no C++ compiler. Gccgo is a GCC front-end that can, with care, be linked with GCC-compiled C or C++ programs. The cgo program provides the mechanism for a “foreign function interface” to allow safe calling of C libraries from Go code. SWIG extends this capability to C++ libraries.

这里的问题是，兼容的实现不需要将类放在compile .cpp文件中。如果编译器可以优化一个类的存在，只要程序在没有它的情况下也能以同样的方式运行，那么它就可以从输出可执行文件中删除。

C语言有一个标准的二进制接口。因此，您将能够知道您的函数被导出了。但是c++背后并没有这样的标准。

你正走在一个未知的领域。这里是调用C代码的Go示例，也许在阅读了c++命名混乱和调用约定以及大量的试验和错误之后，您可以做一些类似的事情。

如果你还想尝试，祝你好运。

从go1.2+开始，cgo自动合并和编译c++代码:

您可能需要向Golang/CGo的LDFlags添加-lc++来识别对标准库的需求。
