|

In Go 1.15.3 and later, cgo will not permit Go code to allocate an
|
||||
undefined struct type (a C struct defined as just <code>struct
|
||||
S;</code> or similar) on the stack or heap.
|
||||
Go code will only be permitted to use pointers to those types.
|
||||
Allocating an instance of such a struct and passing a pointer, or a
|
||||
full struct value, to C code was always unsafe and unlikely to work
|
||||
correctly; it is now forbidden.
|
||||
The fix is to either rewrite the Go code to use only pointers, or to
|
||||
ensure that the Go code sees the full definition of the struct by
|
||||
including the appropriate C header file.
