源洞察中找不到符号

Question

我使用source insight构建项目php内部源代码。当我读到“zend.h”中的代码时，就像这样

typedef struct {
    zend_error_handling_t  handling;
    zend_class_entry       *exception;
    zval                   *user_handler;
} zend_error_handling;`

我想使用“跳转到定义”来查找zend_class_entry，但它告诉我“未找到符号”。实际上这不是真的。 zend_class_entry的定义位于文件zend.h中，如下所示：

typedef struct _zend_class_entry zend_class_entry;

....

struct _zend_class_entry {
char type;
char *name;
zend_uint name_length;
struct _zend_class_entry *parent;
int refcount;
zend_bool constants_updated;
zend_uint ce_flags;

HashTable function_table;
HashTable default_properties;
HashTable properties_info;
HashTable default_static_members;
HashTable *static_members;
HashTable constants_table;
const struct _zend_function_entry *builtin_functions;

union _zend_function *constructor;
union _zend_function *destructor;
union _zend_function *clone;
union _zend_function *__get;
union _zend_function *__set;
union _zend_function *__unset;
union _zend_function *__isset;
union _zend_function *__call;
union _zend_function *__callstatic;
union _zend_function *__tostring;
union _zend_function *serialize_func;
union _zend_function *unserialize_func;

zend_class_iterator_funcs iterator_funcs;

/* handlers */
zend_object_value (*create_object)(zend_class_entry *class_type TSRMLS_DC);
zend_object_iterator *(*get_iterator)(zend_class_entry *ce, zval *object, int by_ref TSRMLS_DC);
int (*interface_gets_implemented)(zend_class_entry *iface, zend_class_entry *class_type TSRMLS_DC); /* a class implements this interface */
union _zend_function *(*get_static_method)(zend_class_entry *ce, char* method, int method_len TSRMLS_DC);

/* serializer callbacks */
int (*serialize)(zval *object, unsigned char **buffer, zend_uint *buf_len, zend_serialize_data *data TSRMLS_DC);
int (*unserialize)(zval **object, zend_class_entry *ce, const unsigned char *buf, zend_uint buf_len, zend_unserialize_data *data TSRMLS_DC);

zend_class_entry **interfaces;
zend_uint num_interfaces;

char *filename;
zend_uint line_start;
zend_uint line_end;
char *doc_comment;
zend_uint doc_comment_len;

struct _zend_module_entry *module;
};

与zval相同。我很困惑，有人可以帮助我吗？ -_- 谢谢。
