protobuf 提示冲突问题 error: conflicting declaration of C function?

Question

写了个 a.cpp 文件，编译的时候却报错。
编译：g++ -std=c++ -lprotobuf a.cpp

报错如下：

/usr/local/include/google/protobuf/endian.h: In function ‘uint32_t google::protobuf::internal::big_endian::ToHost(uint32_t)’:
/usr/local/include/google/protobuf/endian.h:174:17: error: conflicting declaration of C function ‘uint32_t google::protobuf::internal::big_endian::ToHost(uint32_t)’
 inline uint32_t ToHost(uint32_t value) {
                 ^~~~~~
/usr/local/include/google/protobuf/endian.h:166:17: note: previous declaration ‘uint16_t google::protobuf::internal::big_endian::ToHost(uint16_t)’
 inline uint16_t ToHost(uint16_t value) {

但是打开/usr/local/include/google/protobuf/endian.h文件，看166行和174行并不冲突。

166 inline uint16_t ToHost(uint16_t value) {
167 #if defined(PROTOBUF_BIG_ENDIAN)
168   return value;
169 #else
170   return BSwap16(value);
171 #endif
172 }
173
174 inline uint32_t ToHost(uint32_t value) {
175 #if defined(PROTOBUF_BIG_ENDIAN)
176   return value;
177 #else
178   return BSwap32(value);
179 #endif
180 }

Answer 1

你的平台上是不是把 uint16_t 跟 uint32_t 定义成一样的东西了?

我遇到了同样的问题，请问楼主最后。。。。
