Symbols not resolving in NSight

I’m running CUDA 5.5, NSight 3.2.1 and Visual Studio 2010. NSight stops happily at breakpoints, but refuses to resolve any symbols (apart from threadIdx and blockIdx).

-G is set correctly (I believe):

“C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v5.5\bin\nvcc.exe” --use-local-env --cl-version 2010 -ccbin “C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin” -rdc=true -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v5.5include" -I"C:\Program Files (x86)\NVIDIA GPU Computing Toolkit\CUDA\v5.5\CUDASamples\common\inc" -I"C:\Users\pcox\checkouts\HPP_gpu" -G --keep-dir Debug -maxrregcount=0 --machine 32 --compile -cudart static -g -Xcompiler "/EHsc /nologo /Zi /MTd " -o Debug%(Filename)%(Extension).obj “%(FullPath)”[/i]

“C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v5.5\bin\nvcc.exe” -dlink -o Debug\gpu-image-compress_D.device-link.obj -Xcompiler "/EHsc /nologo /Zi " -G

The only complication may be that I’ve been working with separate compilations recently (hence “-rdc” above). Not sure if that can affect this…

Any ideas really welcome!

Combined the three .cu files into one on the hunch that it is a “separate compilation” thing, and now it’s working (even with “-rdc” still in place, and the nvcc line remaining as above). Strange…

Hi Sedona,

any chance you could be linking against non-debug versions of the objects? …if not, any chance you could share your project with us? Thanks

It’s been a year since this post, but I am having a similar problem, although I am using Nsight 3.2.2 and Visual Studio 2012

I’m not sure whether or not it’s completely the fault of the -rdc option because I made a small pet project with multiple .cu files, and the -rdc option, but the debugging seems to be working fine. However, applying the same settings to my more complex project with SEVERAL more classes, I can’t view any of the symbols.

Specifically, when I set a break point and look at the locals I get things like

and demangled look something like…

vtable for std::_error_category
vtable for std::_Generic_error_category


Is there a way for you to share this project with us? You can PM me.
