Question

我按照here的指示，从头开始用Mingw设置Lua和Luarocks。一切正常，我能够安装岩石，包括需要像LuaSocket一样进行编译的岩石。

我按照Torch7页面上的说明通过luarocks安装Torch。但它失败了。我不明白为什么。

这是控制台输出。我最好的猜测是，当我想要使用Mingw时，它与Building for: Visual Studio 9 2008有关。

Answer 1

该命令看起来大致正确，但我认为cmake命令需要-G "MSYS Makefiles"选项来使用mingw而不是VS.您可能还需要提取最新的火炬版本，因为它包含several changes，修复了mingw的一些编译问题。

请注意，我没有使用LuaRocks测试更改，也不确定如何将其他选项传递给它，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））。

cmake 似乎使用Visual Studio 9 2008，但它错误地＃34;使用 mingw32-make.exe 而不是...... nmake.exe 。在执行"c:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat"命令之前，您可以在同一控制台中运行此命令：luarocks（适应您的visual studio路径）。现在， cmake 应该使用 nmake 。

在Windows上使用Luarocks安装带有mingw构建错误的Torch7
