lua - 在 Windows 上使用 Luarocks 安装 Torch7 时出现 mingw 构建错误

Question

我按照说明操作 here并使用 Mingw 从头开始​​设置 Lua 和 Luarocks。一切正常，我能够安装岩石，包括像 LuaSocket 这样需要编译的岩石。

我按照 Torch7 上的说明进行操作通过 luarocks 安装 Torch 的页面。但它无法构建。我不理解为什么。

这是控制台输出。我最好的猜测是它与Building for: Visual Studio 9 2008有关。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"使用 mingw 而不是 VS 的选项。您可能还需要拉取最新的 Torch 版本，因为它包含 several changes修复了 mingw 的一些编译问题。

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