问题描述
尝试构建AOSP版本并出现此错误
错误:初始化了typedef'int32'(改用decltype)
错误:未在此范围内声明“ loc_event_cb_f_type”
这是引发错误的声明
typedef int32 (loc_event_cb_f_type)(
rpc_loc_client_handle_type loc_handle,/* handle of the client */
rpc_loc_event_mask_type loc_event,/* event mask */
const rpc_loc_event_payload_u_type* loc_event_payload /* payload */
);
这是完整的文件:/libloc_api-rpc/rpc_inc/loc_api_rpc_glue.h
#ifndef LOC_API_RPC_gluE_H
#define LOC_API_RPC_gluE_H

你有什么主意吗?
解决方法
问题是int32没有在任何地方定义或包含
@luserdroog写道,
应该是int32_t吗?
int32_t和其他intX_t typedef是在/usr/include/stdint.h中定义的,因此可以通过将所有int32替换为int32_t来解决,也可以按照@JonathanLeffler的建议定义int32类型来解决,这更加方便和简洁。
typedef uint32_t uint32;
但要解决其他文件的问题,
将此声明添加到/usr/include/stdint.h将起作用
