使用 Code::Blocks 和 MinGW 构建 Assimp

Question

我正在尝试使用 Code::Blocks 和 MinGW 作为静态库来构建 Assimp。我已经下载了最新的可用版本 (5.0.1) 并使用 cmake-gui 为 Code::Blocks 创建了一个生成文件。我可以使用 Code::Blocks 打开该文件，但是当我尝试构建它时会失败。这是完整的日志：

我不是很熟悉所有构建的东西，但看起来 zlib 有一些问题。如何解决该问题并使用我拥有的编译器构建库？

我不想切换到 msys2。

在我切换到 Assimp 5.1.6 版本之后，它变得更有价值，cmake 无法生成 makefile：

可能是这个原因：

但我不知道所有这些makefile stuf。

甚至移到了 3.0 版，但仍然无法使用 cmake。至少那个版本有办法绕过那个 anoing cmake。有一个 Visual Studio 项目，我可以像这样打开并选择 noboost 版本：

但即使选择了那个选项，也有很多关于提升的错误。但是有一些与 boost 无关的错误消息对我来说毫无意义：

C:\...\assimp--3.0.1270-source-only\code\StringComparison.h||In function 'int Assimp::ASSIMP_stricmp(const char*, const char*)':|
C:\...\assimp--3.0.1270-source-only\code\StringComparison.h|137|error: '::strcasecmp' has not been declared|
C:\...\assimp--3.0.1270-source-only\code\StringComparison.h||In function 'int Assimp::ASSIMP_strincmp(const char*, const char*, unsigned int)':|
C:\...\assimp--3.0.1270-source-only\code\StringComparison.h|186|error: '::strncasecmp' has not been declared|

strcasecmp 和 strncasecmp 都来自 string.h，但包括 string.h 并没有改变任何东西。

正如here 所见，我不是唯一一个有这个问题的人。因此，该线程中的解决方案适用于 strcasecmp 和 strncasecmp，但由于这种 anoing 提升，仍然存在很多错误。

目前最新的 assimp 版本是5.1.6，所以看起来你有点落后了。

该版本使用 MinGW-w64 构建。我使用 CMake 和 Ninja 构建它。我使用以下 CMake 标志：-DASSIMP_BUILD_ASSIMP_TOOLS:BOOL=ON -DASSIMP_HEADERCHECK:BOOL=OFF -DASSIMP_OPT_BUILD_PACKAGES:BOOL=OFF -DSYSTEM_IRRXML:BOOL=OFF -DASSIMP_BUILD_SAMPLES:BOOL=OFF -DBUILD_DOCS:BOOL=OFF -DASSIMP_BUILD_TESTS:BOOL=OFF -DCMAKE_CXX_FLAGS:STRING="-Wno-array-bounds -Wno-alloc-size-larger-than -Wno-error=array-compare"
