Cmake无法正确生成简单解决方案[Windows 10] [英] Cmake not generating assimp solutions properly [Windows 10]

问题描述

Cmake 3.15 32位

Assimp 4.1.0

你好，我在cmake和assimp方面遇到了一些困难。在过去的几天里，我一直在尝试通过cmake为CodeBlock生成一个简单的工作区。

我已尝试使用CMD和Cmake GUI方法生成解决方案，但未获得令人满意的结果。

在图形用户界面中，遵循生成项目的标准过程，然后定义适当的源路径和目标路径，并选择适当的生成器(CodeBlockMinGW生成文件)。

cmd中用于生成assimp项目的代码：

cmake -G "CodeBlocks - MinGW Makefiles" MakeLists.txt -S "source path" -B "build path"

生成文件后获取的信息日志：

  behavior and not rely on setting a policy to OLD.

遗憾的是，该项目无法在CodeBlock中生成，生成日志如下：

免责声明：

自然地，我已经搜索并尝试了网络上针对这个特定问题的所有现有解决方案[1]，但令人失望的是，这些解决方案都不起作用。老实说，我对编译和库了解不多，但在我看来，当阅读错误日志时，我会说问题源于zlib文件，对吗？有人能帮我解决这个问题吗？提前谢谢您。

推荐答案

该问题是由错误检测到的环境引起的。Zlib脚本尝试对windows-resource-Build使用以下选项：

C:MinGWinwindres.exe -D GCC_WINDRES -I C:/Users/ognje/Downloads/assimp-4.1.0/contrib/zlib -I "E:/Assimp/contrib/zlib" -o "E:/Assimp/contrib/zlib/zlib1rc.obj" -i C:/Users/ognje/Downloads/assimp-4.1.0/contrib/zlib/win32/zlib1.rc

选项-i将被标识为文件令牌：

gcc: error: i: No such file or directory

因此zlib的构建失败，因为用作参数的选项混淆了以下内容的GCC解析，在本例中是目标zlib：

gcc: error: Assimp/contrib/zlib: No such file or directory

我猜这是由于在使用您的特殊版本的mingw时，必须构建哪些代码的标识丢失所致。您可以打开一个问题报告与VeYou可以做版本的assimp你正在使用和哪个版本的GCC-在您的版本中使用。您可以在此处执行此操作：Issue-tracker of Asset-Importer-Lib Project
