英文:
GDB can't debug the go program within cgo code
问题
#example files
src/test.go
package main
import (
. "clib"
)
func main() {
a := "123";
b := "456";
c := "789";
println(a,b,c);
Output("ABC");
}
src/clib/clib.h
#ifndef CLIB
void output(char* str);
#endif
src/clib/clib.c
#include "clib.h"
#include <stdio.h>
void output(char* str)
{
printf("%s\n", str);
}
src/clib/clib.go
package clib
/*
#cgo CFLAGS:-g
#include "clib.h"
*/
import "C"
func Output(s string) {
p := C.CString(s);
C.output(p);
}
#exec code
go build -gcflags "-N -l" test.go
gdb ./test
b 10
r
info locals // <- every variable's value is wrong!
Who can help me solve this problem, thank you very much.
My Environment:
- ubuntu 11.04 i386
- gdb 7.6
- go 1.1

目前有一个关于这个问题的未解决bug：https://code.google.com/p/go/issues/detail?id=5221
在1.0版本中，使用gdb调试cgo是可行的，但在1.1版本中目前存在问题。正在进行修复。

There is currently an open bug regarding this: https://code.google.com/p/go/issues/detail?id=5221
Debugging cgo with gdb worked in 1.0 but is currently broken in 1.1. It's being worked on.
