在 Windows 上使用 Luarocks 安装 Torch7 并出现 mingw 构建错误

我按照说明进行操作here并与 Mingw 从头开始​​建立 Lua 和 Luarocks。一切工作正常，我能够安装rocks，包括那些需要像LuaSocket这样编译的东西。

我按照说明进行操作Torch7通过 luarocks 安装 Torch 的页面。但它构建失败。我不懂为什么。

这是控制台输出。我最好的猜测是它与Building for: Visual Studio 9 2008当我想我想要它使用 Mingw 时。

该命令看起来基本正确，但我认为 cmake 命令需要-G "MSYS Makefiles"选择使用 mingw 而不是 VS。您可能还需要获取最新的火炬版本，因为它包括一些变化修复了 mingw 的一些编译问题。

请注意，我尚未使用 LuaRocks 测试更改，并且不确定如何将该附加选项传递给它，但您应该能够手动运行相同的命令以获得所需的结果（我从命令行编译它）。
