gdb我在我本机上p不了，在别人机子上可以，不知道什么

(gdb) p EventFlow->devicetype
There is no member or method named devicetype.
(gdb) p (EventFlow->devicetype)
There is no member or method named devicetype.
(gdb) n
403 EventFlow->DspLen = log_size;
(gdb) p log_size
$4 = 682
(gdb) p EventFlow->DspLen
There is no member or method named DspLen.
(gdb) p (char*)EventFlow->DspLen
There is no member or method named DspLen.
(gdb) p (char*)EventFlow->DspLen
There is no member or method named DspLen.
(gdb)
There is no member or method named DspLen.
(gdb) p EventFlow
$5 = {px = 0xf856d0, pn = {pi_ = 0xf15890}}
(gdb) p (int)(EventFlow->devicetype)
There is no member or method named devicetype.
(gdb) p (int*)(EventFlow->devicetype)
There is no member or method named devicetype.

 =======================================

这样可以
(gdb) ptype EventFlow
type = class boost::shared_ptr<STEVENTFLOW> {
private:
STEVENTFLOW *px;
boost::detail::shared_count pn;

public:

}
