在Windows上使用mingw构建错误在Luarocks上安装Torch7 [英] Installing Torch7 with Luarocks on Windows with mingw build error

问题描述

我按照此处的说明进行操作，并从头开始设置Lua和Luarocks，明哥一切工作正常，我能够安装岩石，包括需要像LuaSocket这样进行编译的岩石.

I followed the instructions here and set up Lua and Luarocks from scratch, with Mingw. Everything worked fine and I was able to install rocks, including ones which require compiling like LuaSocket.

我按照 Torch7 页上的说明进行操作，以通过羽扇安装Torch.但是它无法构建.我不明白为什么.

I followed the instructions on the Torch7 page to install Torch via luarocks. But it fails building. I do not understand why.

这是控制台输出.我最好的猜测是，当我认为我希望它使用Mingw时，它与Building for: Visual Studio 9 2008有关.

Here is the console output. My best guess is that it has something to do with Building for: Visual Studio 9 2008 when I think I want it to use Mingw.

推荐答案

该命令看起来基本上是正确的，但是我认为cmake命令需要-G "MSYS Makefiles"选项才能使用mingw而不是VS.您可能还需要拉出最新的割炬版本，因为它包含一些更改 mingw的编译问题.

The command looks mostly correct, but I think the cmake command needs -G "MSYS Makefiles" option to use mingw instead of VS. You may also need to pull the most recent torch version as it includes several changes that fix some compilation issues with mingw.

请注意，我尚未使用LuaRocks测试更改，并且不确定如何将其他选项传递给它，但是您应该能够手动运行相同的命令以获得所需的结果(我从命令行对其进行了编译).

Note that I haven't tested the changes with LuaRocks and not sure how to pass that additional option to it, but you should be able to run the same command manually to get the desired result (I compiled it from the command line).
