So I am try to get a simple CGO program going with a GO function that can
get called back from a 'C' library
the error I get is
In file included from _cgo_export.c:3:
cgo-gcc-export-header-prolog:42:14: error: conflicting types for
'_go_Callback'
src/smsdk/go_bindings.go:12:12: note: previous declaration is here
_cgo_export.c:17:7: error: conflicting types for '_go_Callback'
src/smsdk/go_bindings.go:12:12: note: previous declaration is here
The code is simple looks like this
package smsdk
/*
#cgo CFLAGS: -Damd64 -D SM_SDK_INTERNAL -I ${SRCDIR}/smsdk
#cgo LDFLAGS: -L${SRCDIR} -lsm_sdk
#include <stdbool.h>
#include <stdlib.h>
#include "sm_sdk.h"
extern int _go_Callback(int speaking_state);
static void Callback(Handle h, void * caller_context)
{
int val = CLibraryFunction(h);
_go_Callback(val);
}
*/
import "C"
import (
"unsafe"
"sync"
)
var _registeredCallback func(int)
//export _go_SpeakingStateCallback
func _go_SpeakingStateCallback(val int) int {
if _registeredCallback != nil {
_registeredCallback(val)
return 1
}
return 0
}
Any suggestions?
