我想在自由线程版Python 3.13t上使用wxPython，但目前没有可用的wheel安装包，只能尝试从源码编译安装，过程中遇到了两个问题，其中第二个问题至今没有解决，在此向各位求助。

问题1：Pip源码编译时提示依赖缺失 #

已解决的方案： #

手动安装了wheel, setuptools, six，还有wxPython源码压缩包中\requirements\install.txt和\dev.txt里列出的所有依赖包；我已经安装了Visual Studio 2019，所以不需要额外安装C++构建工具，这一步顺利解决。

问题2：核心库编译成功，但第一个扩展库（nano-svg）编译失败 #

问题现状： #

核心库编译完成后，编译第一个扩展库nano-svg时Pip报错，目前没有找到可行的解决方案。错误根源似乎和Cython文件中的__pyx_vectorcallfunc相关，编译时的完整错误日志如下：

目前的排查进展 #

我已经做了一些尝试，但都没有解决问题：

• 确认__pyx_vectorcallfunc未被识别的问题，大概率和Cython与自由线程版Python 3.13t的兼容性相关
• 发现其他项目（如scipy）的仓库中也出现过类似问题，被归因于过时的Cython版本
• 虽然wxPython官方要求的Cython版本是3.0.10，但我先后升级到了稳定版3.0.12，甚至从Git master分支编译安装了Alpha版3.1.x，依然无法绕过__pyx_vectorcallfunc的错误

求助问题 #

想请教各位有经验的开发者：

1. 有没有人成功在自由线程版Python 3.13t上从源码编译出wxPython的wheel包？
2. 我应该优先把这个问题反馈给wxPython的开发团队/Git仓库，还是暂时等待官方的兼容性更新？
3. 有没有其他临时的 workaround 可以让我在3.13t上成功编译并使用wxPython？
