golang runtime-gdb.py的问题

问题：

(gdb) source /Users/sherlock/documents/go/src/runtime/runtime-gdb.py
Loading Go Runtime support.
Traceback (most recent call last):
  File "/Users/sherlock/documents/go/src/runtime/runtime-gdb.py",line 205,in <module>
    _rctp_type = gdb.lookup_type("struct runtime.rtype").pointer()
gdb.error: No struct type named runtime.rtype.

解决方案:

1. git clonehttps://github.com/golang/example.git

2.在stringutil目录下 go test -c ./

3.

gdb -q ./stringutil.test
Reading symbols from ./stringutil.test...done.
(gdb) source /usr/src/go/src/runtime/runtime-gdb.py
Loading Go Runtime support.
Traceback (most recent call last):
  File "/usr/src/go/src/runtime/runtime-gdb.py",in <module>
    _rctp_type = gdb.lookup_type("struct runtime.rtype").pointer()
gdb.error: No struct type named runtime.rtype.
(gdb) set pagination off
(gdb) set logging on
Copying output to gdb.txt.
(gdb) info types
# much output
(gdb) quit

4.命令行

grep runtime gdb.txt   | grep type;

struct []*runtime._type;
typedef struct runtime.iface error;
typedef struct runtime.iface flag.Value;
typedef struct runtime.iface flag.boolFlag;
typedef struct runtime.iface fmt.Formatter;

typedef void (struct runtime.stkframe *,void *,bool *) func(*runtime.stkframe,unsafe.Pointer) bool;
typedef void (struct []runtime.StackRecord,int *,bool *) func([]runtime.StackRecord) (int,bool);
typedef struct runtime.iface interface { runtime.f() };

typedef struct runtime.iface os.FileInfo;
typedef struct runtime.iface os.Signal;
typedef struct runtime.iface reflect.Type;
typedef struct runtime.iface regexp.input;
struct runtime._type;
typedef runtime.bucketType;
struct runtime.chantype;
typedef struct runtime.iface runtime.fInterface;
struct runtime.functype;
struct runtime.interfacetype;
typedef runtime.intptr;
struct runtime.maptype;
typedef runtime.pageID;
struct runtime.ptrtype;
struct runtime.slicetype;
typedef struct runtime.iface runtime.stringer;
struct runtime.typeAlg;
typedef runtime.uintreg;
struct runtime.uncommontype;
typedef struct runtime.iface runtime/pprof.countProfile;
typedef struct runtime.iface sort.Interface;
typedef struct runtime.iface sync.Locker;

注：我的平台是mac os x 10.10.3,go1.4.2

其他平台可能不是

struct []*runtime._type;
