【问题描述】：
我最近在我的“Windows Vista Home Premium”机器上下载了“Microsoft Visual C++ 2010 Express”版本。我是一名试图切换到 C++ 的 Java 程序员，这非常令人沮丧：
- 我打开 Visual C++
- “文件 -> 新建 -> 项目...”
- 选择“Win32 应用程序”，默认、默认、默认等...“完成”
- 右键单击解决方案（或项目）->“构建”
-
输出窗口显示，
------ Build started: Project: Engine, Configuration: Debug Win32 ------ LINK : fatal error LNK1104: cannot open file 'Debug\Engine.obj' ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
我有时也会收到“LNK1181”错误。问题是编译器找不到这些对象，但如果我没记错的话，编译器应该在编译期间自动生成这些 .obj 文件。我检查了 'Engine.obj' 的 'Debug' 文件夹 - 它是一个空文件夹。那么，为什么 Visual C++ 不创建这些 .obj 文件呢？谁能客观地告诉我为什么 Visual C++ 不会生成这些 .obj 文件？
作为旁注，我有一个暗示，这可能与我的系统类型（x32 与 x64）有关。我很确定我在基于 x64 的硬件上运行“Windows Vista Home Premium (x32)”。我遇到了 Microsoft Silverlight（当然是 Microsoft！）为我提供错误 .exe 的问题，因为该网站使用我的硬件凭据来确定适合我的计算机的版本。 x64 不会安装在我的机器上，但是当我转到“系统信息”时，在“系统类型”下会显示“基于 x64 的 PC”。后来安装的x32版本就好了。可能是我使用的 Visual C++ 版本存在兼容性问题？
更新：我尝试安装 x64 版本的 Visual Studio 2010 - 没有。同样的问题。

【问题讨论】：
-
你有 Engine.cpp 吗？如果有，里面有什么？
-
你能把你的编译详细程度设置为诊断，然后清理然后重建吗？
-
在哪里设置编译器详细程度？我尝试了许多清理/重建的变体，并且尝试在调试/发布模式下进行编译。什么都没有。
-
尝试从项目中移除Engine.cpp，然后通过菜单项ADD Existing Item....添加它，然后尝试编译它
-
请执行
Build/Rebuild Solution然后找到Debug\Engine.log文件（假设您将项目命名为“Engine”）并将其内容发布到您的问题中。
