Summary

0012099: Unable to quote cmd line args to be passed to nvcc

Description

I am trying to build a CUDA project with Visual Studio 2010 and CMake.

I know that this is a sensitive issue.

Basically, I get a compilation error when nvcc tries to parse a stddef.h file, and runs into the use of an undefined macro named "nullptr".

A colleague of mine had patched my VS2010/CUDA setup so that with an ordinary VS project I can properly compile CUDA source files into .obj. One of the steps involved changing the VS rules so that the command line includes the following text:

-Xcompiler "/Dnullptr=0 /Dnullptr_t=__nullptr_t /D__nullptr=((void*)0)"

The quotation marks are essential, because otherwise the parentheses around the (void *) are parsed incorrectly. As you can see, the missing macros are defined, so that the original problem is bypassed.

However hard I tried, I could not produce the proper quotation marks to be passed as nvcc command line arguments. It came to a point that when I take the command line produced within the CMake-generated VS project (using Verbose mode), and simply add the above options, my source file get compiled. But I can't get CMake to produce the same outcome.

Example: Use the OPTIONS flag on the cuda_add_library. By default, this simply separates the -Xcompiler from the rest of the stuff, and creates an invalid command line, where "Xcompiler" becomes one of the options for Xcompiler. If I remove the "-Xcompiler" then I can't get the quotation right around the options, and then the parentheses scramle things up.

It looks as though something is wrong in the way that the OPTIONS are parsed. I can't pinpoint the issue, and I can't get around it.

Steps To Reproduce

You can use an empty .cu file.

project(Test_CMake)

find_package(CUDA)

if(NOT CUDA_FOUND)
message(SEND_ERROR "CUDA package not found!")
endif()

cuda_add_library(Test_CMake emptyfile.cu)

Try the various options.
