如何配置mex以将编译器标志传递给nvcc [英] How can one configure mex to pass compiler flags to nvcc

问题描述

使用nvcc编译mex文件时，由于mex无法识别它们，因此我一直难以将CUDA特有的编译器选项传递给nvcc编译器.

While compiling mex files with nvcc I have struggled to pass compiler options specific to CUDA to the nvcc compiler, as mex doesn't recognize them.

我找到了一些一些较新的版本， 但是问题是非常特定于用户的，并且mex编译器多年来已经发生了变化，所以我不知道该怎么做.

I found some old posts about passing compiler flags and some newer ones, but the questions are quite user-specific, and the mex compiler has changed over the years, so I cant figure out what to do.

所以，我的具体问题是:我应该怎么做才能使mex将编译器标志传递给nvcc?

So, my specific question: What should I do to make mex pass compiler flags to nvcc?

更通用一些:如何使mex将编译器标志传递给另一个编译器?

A bit more generic: What should one do to make mex pass compiler flags to another compiler?

推荐答案

如果使用最新的编译方式(其中选项位于xml文件中)，则可以在其中硬编码默认的编译标志.例如我的样子:

If working with the newest compiling way where the options are in an xml file, one can hardcode the default compile flags in there. For example mine looks like:

COMPILER="nvcc"
      COMPFLAGS="-gencode=arch=compute_20,code=sm_20 -gencode=arch=compute_30,code=sm_30 -gencode=arch=compute_35,code=sm_35 -gencode=arch=compute_50,code=\"sm_50,compute_50\" --compiler-options=/c,/GR,/W3,/EHs,/nologo,/MD"
      COMPDEFINES="--compiler-options=/D_CRT_SECURE_NO_DEPRECATE,/D_SCL_SECURE_NO_DEPRECATE,/D_SECURE_SCL=0,$MATLABMEX"
      MATLABMEX="/DMATLAB_MEX_FILE"
      OPTIMFLAGS="--compiler-options=/O2,/Oy-,/DNDEBUG"
      INCLUDE="-I"$MATLABROOT\extern\include" -I"$MATLABROOT\simulink\include""

  DEBUGFLAGS="--compiler-options=/Z7"

一个人可以更改修改COMPFLAGS
