C ++ Ogre运行时错误“断言失败”

Question

调试断言失败！

程序：... ments \\ Visual Studio 2013 \\ Projects \\ OgreTest \\ Debug \\ OgreTest.exe
文件：f：\\ dd \\ vctools \\ crt \\ crtw32 \\ misc \\ dbgheap.c
线：1424

表达式：_pFirstBlock == pHead

有关程序如何引起断言的信息
失败，请参见有关断言的Visual C ++文档。

（按重试可调试应用程序）

这就是我尝试执行Ogre应用程序时得到的。 来源是Ogre教程框架的完整副本。 我从Ogre.log中发现了很多荒谬的异常。 似乎所有错误都来自OgreGpuProgramParams.cpp和OgreResourceGroupManager.cpp 。 接下来的一些第一批。 我无法全部粘贴它们，因为大约有1000行。

注意，这些错误仅在使用OpenGL或D3D9渲染系统时出现。 使用D3D11时，运行时错误有所不同：

OGRE EXCEPTION（3：RenderingAPIException）：尝试渲染到既没有顶点着色器又没有片段着色器的D3D11设备，d3d11中没有固定的管道-使用RTSS或编写自定义着色器。 在.......... \\ RenderSystems \\ Direct3D11 \\ src \\ OgreD3D11RenderSystem.cpp的D3D11RenderSystem :: _ render中（第2496行）

如果有必要，我可以粘贴更多信息。 有人知道解决方案吗？

Answer 1

如果您混用发行版和调试版，则通常会出现此错误。 在这种情况下，如果您尝试使用调试生成DLL，则很可能是在发布模式下构建了您的应用程序。

您可以使用Dependency Walker之类的工具来检查在应用程序运行期间准确加载了哪些DLL。

另一个原因可能是您的Ogre DLL是由与实际应用程序不同的IDE /编译器版本生成的。 这通常会使它们与二进制不兼容，从而导致崩溃。 这可能是由于标准库的版本不同以及相关的动态分配问题引起的。 如果将Ogre库构建为“静态”，但使用动态依赖项（例如OIS，​​插件等），则可能会发生同样的情况。

关于日志中的错误：您似乎缺少引起这些日志条目的某些媒体文件（例如，着色器）。

关于D3D11：Microsoft使用该版本删除了FFP（固定功能管道）。 因此，现在所有内容都是基于着色器的，这意味着您要么必须自己编写/提供这些着色器，要么使用Ogre的集成着色器生成器（ RTTS ）。
