c++ - Visual Studio 2010 C++/w Google Protocol Buffer 。找不到 60 个外部对象。无法编译

Question

我已尽我所能按照说明进行操作。下载的 GPBuffers 5.0rc1 将 src/google 文件夹放入我的项目目录。添加了设置> C/C++ >“其他包含目录”的路径。

但我想我需要在某处放置一个 -lprotobuf 编译器选项。我尝试将其添加到设置 > xxx > 附加命令行参数中的 C/C++ 和链接器。

但运气不好。

似乎缺少 libprotobuf.lib、libprotobuf-lite.lib 和 libprotoc.lib。也许它没有正确构建..

我有我的 serverThread.cpp，它看起来像:

#include "serverThread.h"
#include "sendStruct.h"

#include <fstream>
#include <string>
#include "messages.pb.h"

日志转载如下。

它似乎缺少对某个库的引用。因为大多数依赖项都在那里。

需要正确编译 Protobuf。有一个 vsprojects 文件夹。只需构建 libprotobuf 并将 libprotobuf.lib 添加为对项目的引用，方法是:

如果你把它复制到你的项目文件夹/google 放在 google/libprotobuf.lib

现在一切都应该顺利编译。
