Kind is incomplete or unallocatable – Code Assessment

I’m writting a C++ wrapper.
Think about the next venture:
src.cpp

#embrace "src.h"
struct SourceType {
        int foo;
};

src.h:

struct SourceType;

c.h is a C wrapper of this C++ code:

typedef struct SourceType SourceType;
struct SourceType;

wrapper.h is a wrapper for GO:

#pragma as soon as
#embrace "c.h"

fundamental.go:

package deal fundamental

/*
#embrace "wrapper.h"
*/
import "C"

func fundamental() {
	var foo C.SourceType
	_ = foo
}

I’m getting the next error:

# instance.com
./fundamental.go:9:6: _Ctype_struct_SourceType is incomplete (or unallocatable); stack allocation disallowed

oh, okay, obtained it. I can’t allocate this object, I must allocate a pointer

Hello @gucio321,
I’m operating up in opposition to the very same concern doing a go-binding to a c/c++ venture. Might you please inform me what you imply by, ” I can’t allocate this object, I must allocate a pointer.”? I wish to discover ways to remedy this for my venture as effectively. Thanks!

By no means thoughts. I perceive your remark and was in a position to make the identical modifications.
