Jump to C++functions

[ArthurZangCN]

My project is a mixed code project of Golang and C++. Golang calls functions encapsulated in C++, and C++function definitions use the prefix extern "C" func. Golang uses import "C" and calls C.func. Currently, this method has a red wavy line indicating that the definition cannot be found and cannot be jumped.

@ArthurZangCN , can you provide screenshot and more information about what/how you are trying to call ?

@ArthurZangCN I think this is a limitation in the Go compiler. I believe the Go-C translation layer isn't created until you compile your program. Does the problem persist after you compile?

For example, I have a type conversion function encapsulated in C++that converts Golang's data type to C++'s data type
void* allocFun(int a, int b, int c)
{
... ...
return (struct myDef *)tmp;
}
I have a golang encapsulated API that calls allocFun
import "C"
func prepareA(requestJson []byte) {
// byte to json

var p unsafe.Pointer
p = C.allocFun(C.int(a), C.int(b), C.int(c))

}
For the convenience of management, these cpp and go source codes are placed in the same project directory, but will be compiled separately. In this case, if you jump to allocFun in go, you will not be able to find the definition, and there will be red wavy lines on the page.

There are no strict language type restrictions for Linux projects. I will mix my C++and Golang languages in the same project directory. Although they will be compiled separately, they will be written simultaneously when writing code. In this case, it would be very convenient to jump from Go to C++defined functions, but now I can only use search.
