英文:
could not determine kind of name for C.free
问题
我正在尝试在我的 Golang 应用程序中使用 C.free。我的代码如下所示：
package main
import (
"fmt"
"unsafe"
)
// #include <stdlib.h>
import "C"
//export FreeMemory
func FreeMemory(pointer *int64) {
C.free(unsafe.Pointer(pointer))
}
我已经进行了一些搜索，我了解到错误是因为我没有包含 stdlib.h，但实际上我已经包含了。
这是我的构建命令：go build --buildmode=c-shared -o main.dll。构建后我得到的错误是：could not determine kind of name for C.free。
我的操作系统是 Windows 10。
谢谢。

I have done some searching and I understand the error was because I don't have stdlib.h included, but I do.
This is my build command: go build --buildmode=c-shared -o main.dll. The error I get after building is: could not determine kind of name for C.free

如果在导入"C"之前有注释，该注释被称为前导注释，并在编译包的C部分时用作头部。例如：
使用紧接Go行注释的方式：
package main
import "unsafe"
// #include <stdlib.h>
import "C"
//export FreeMemory
func FreeMemory(pointer *int64) {
C.free(unsafe.Pointer(pointer))
}
func main() {}
使用紧接Go通用注释的方式：
package main
import "unsafe"
/*
#include <stdlib.h>
*/
import "C"
//export FreeMemory
func FreeMemory(pointer *int64) {
C.free(unsafe.Pointer(pointer))
}
func main() {}
英文:
> If the import of "C" is immediately preceded by a comment, that
> comment, called the preamble, is used as a header when compiling the C

>
> // #include <stdio.h>
> // #include <errno.h>
> import "C"
Using immediately preceding Go line comments:
package main
import "unsafe"
// #include <stdlib.h>
import "C"
//export FreeMemory
func FreeMemory(pointer *int64) {
C.free(unsafe.Pointer(pointer))
}
func main() {}
Using immediately preceding Go general comments:
package main
import "unsafe"
/*
#include <stdlib.h>
*/
import "C"
//export FreeMemory
func FreeMemory(pointer *int64) {
C.free(unsafe.Pointer(pointer))
}
func main() {}
