在GOOGLE_PROTOBUF_MIN_PROTOC_VERSION检查期间进行编译时出现协议缓冲区错误 [英] Protocol Buffer Error on compile during GOOGLE_PROTOBUF_MIN_PROTOC_VERSION check

问题描述

我当前遇到错误，将我指向protoc生成的头文件中的这些行:

I'm currently getting an error which points me to these lines in the header file produced by protoc:

#if 2006001 < GOOGLE_PROTOBUF_MIN_PROTOC_VERSION
#error This file was generated by an older version of protoc which is
#error incompatible with your Protocol Buffer headers.  Please
#error regenerate this file with a newer version of protoc.
#endif

但是我的协议版本与上面的版本匹配:

But my protoc version matches the one above:

protoc --version
libprotoc 2.6.1

我在做什么错了?

最初，我的协议版本是3.0.0，然后通过同步回2.6.1并执行以下步骤来重新安装它； make distclean，./configure，make，make install以安装所需的2.6.1版本.我需要较旧的版本，因为那是我们服务器中安装的版本.

Originally my protoc version was 3.0.0 then reinstalled it by syncing back to 2.6.1 and doing the steps; make distclean, ./configure , make, make install to install the desired 2.6.1 version. I needed the older version since that's the one installed in our servers.

推荐答案

问题是系统上(在/usr/include/google/protobuf或/usr/local/include/google/protobuf中)安装的标头是来自比您的protoc更高版本的协议缓冲区.可能是两个版本都安装在不同的位置，并且使用了错误的版本.

The problem is that the installed headers on your system (in /usr/include/google/protobuf or /usr/local/include/google/protobuf) are from a newer version of Protocol Buffers than your protoc. It may be the case that you have both versions installed in different locations, and the wrong one is being used.

但是我的协议版本与上面的版本匹配:

But my protoc version matches the one above:

是的，因为该代码是由您的protoc生成的，并且它知道自己的版本.该代码会询问:我的版本(2006001)是否低于安装的标头要求的最低版本(GOOGLE_PROTOBUF_MIN_PROTOC_VERSION)?"

Yes, because that code was generated by your protoc, and it knows its own version. The code is asking: "Is my version (2006001) less than the minimum version which the installed headers claim is required (GOOGLE_PROTOBUF_MIN_PROTOC_VERSION)?"
