Getting error "nvcc fatal : '-DNDEBUG': expected a number" while trying to compile matconvnet

[Umair Mukati]

Hi all,

I am trying to compile matconvnet with GPU support. I have "GTX 960M" graphics processor.

I am using the following command to compile Matconvnet:

vl_compilenn('enableGpu',true)

Kindly, help me in overcoming this issue.

P.S.: I have tried all the solution mentioned on the internet but the problem is not resolved.

Best regards,

Umair Mukati

The problem probably because you have to use -o0  on nvcc_compile function inside vl_compilenn.m:

function nvcc_compile(opts, src, tgt, flags)

% --------------------------------------------------------------------

if check_deps(opts, tgt, src), return ; end

flags.base{3} = '-O0';

nvcc_path = fullfile(opts.cudaRoot, 'bin', 'nvcc');

nvcc_cmd = sprintf('"%s" -c -o "%s" "%s" %s ', ...

                   nvcc_path, tgt, src, ...

                   strjoin(horzcat(flags.base,flags.nvcc)));

opts.verbose && fprintf('%s: NVCC CC: %s\n', mfilename, nvcc_cmd) ;

status = system(nvcc_cmd);

if status, error('Command %s failed.', nvcc_cmd); end

try it, i hope is good for you
