nvmex with debug information

Accelerated Computing CUDA CUDA Programming and Performance
1

Hello,

I’ve wrote a cuda-program with matlab interface and I want to compile my program with debug information. When I use the command “nvmex -g -f nvmexoptsemul.bat cuda_SobelFilter.cu -IC:\cuda\include -LC:\cuda\lib -lcudart”, I get the following error:

Usage : nvcc [options]
…
…

C:\PROGRA~1\MATLAB\R2007A\BIN\NVMEX.PL: Error: Compile of ‘cuda_SobelFilter.cu’ failed.

Without the flag -g it works fine.

How can I compile my files with debug information?

Should I make some changes in the nvmexoptemul.bat?

I use WindowsXP, Matlab 7.4.0 R2007a and Visual Studio 2005 and the following nvmexoptemul.bat

@echo off
rem MSVC80OPTS.BAT

Yes, make the changes in the nvmexopt.bat file. You can create a new one for debugging.

Hello,

Which changes should i make?

i’ve made some changes in the COMPFLAGS (-g):

set COMPFLAGS=-g -deviceemu -c -D_WCHAR_T_DEFINED -Xcompiler “/c /Zp8 /GR /W3 /EHsc- /Zc:wchar_t- /DMATLAB_MEX_FILE /nologo”

…but nothing happens. The compiler does not generate the *.pdb with the debug information.

I need this information because afterwards I would like to debug my program with Visual Studio 2005 by attach to Matlab process.

thanks,
volkmar

The flags for the host compiler are the one after -Xcompiler.
I don’t know the compiler flag to enable debug in VisualStudio, but whatever it is, should go there.

thanks for your answer.

With the following changes I was able to generate a *.pdb file.

rem ********************************************************************
set COMPILER=nvcc
set COMPFLAGS=-g -c -D_WCHAR_T_DEFINED -Xcompiler “/Zi /c /Zp8 /GR /W3 /EHsc- /Zc:wchar_t- /DMATLAB_MEX_FILE /nologo”
set OPTIMFLAGS=-D_WCHAR_T_DEFINED -Xcompiler “/MD /Oy-”
set DEBUGFLAGS=-D_WCHAR_T_DEFINED -Xcompiler “/MD /Zi /Fd”%OUTDIR%%MEX_NAME%%MEX_EXT%.pdb"
set NAME_OBJECT=-o
