Error message "Stray '[' character" is shown in MEX building through GPU Coder.

I'm trying making stereo vision depth estimation tool that uses NVIDIA GPU.

The following function "FulHD_Frame_depth_estimation" is entry-point function in generating CUDA code.

function [ptCloudLocation,ptCloudColor] = FullHD_Frame_depth_estimation(frameLeftRect,frameRightRect,reprojectionMatrix)

% Convert to grayscale.
frameLeftGray  = rgb2gray(frameLeftRect);
frameRightGray = rgb2gray(frameRightRect);

% Compute disparity. 
disparityMap = disparitySGM(frameLeftGray, frameRightGray);

% Reconstruct 3-D scene.
points3D = reconstructScene(disparityMap, reprojectionMatrix);
points3D = points3D ./ 1000;
ptCloud = pointCloud(points3D, 'Color', frameLeftRect);

ptCloudLocation = ptCloud.Location;

ptCloudColor = ptCloud.Color;

end

And the following function "FullHD_movie_depth_estimation" is entire estimation code that loads stereo movies.

function FullHD_movie_depth_estimation(left_camera_movie_file_name,right_camera_movie_file_name,stereoparams_file_name)

load(stereoparams_file_name);

videoFileLeft = left_camera_movie_file_name;
videoFileRight = right_camera_movie_file_name;
readerLeft = VideoReader(videoFileLeft);
readerRight = VideoReader(videoFileRight);
frameLeft = readFrame(readerLeft);
frameRight = readFrame(readerRight);

[~, ~, reprojectionMatrix] = ...
    rectifyStereoImages(frameLeft, frameRight, stereoParams);

%Create a streaming point cloud viewer
player3D = pcplayer([-3, 3], [-3, 3], [0, 8], 'VerticalAxis', 'y', 'VerticalAxisDir', 'down');

%while hasFrame(readerLeft) && hasFrame(readerRight)
for i = 1:1
    % Read the frames.
    frameLeft = readFrame(readerLeft);
    frameRight = readFrame(readerRight);

    % Rectify the frames.
    [frameLeftRect, frameRightRect] = rectifyStereoImages(frameLeft, frameRight, stereoParams);

    [pC.Location,pC.Color] = FullHD_Frame_depth_estimation(frameLeftRect,frameRightRect,reprojectionMatrix);
    
    view(player3D, pC.Location,pC.Color);
    
end
end

In GPU Coder, MEX of "FullHD_Frame_depth_estimation" failed to be built in using GPU.

Each error message tells "Stray '[' character." I think generated MEX functions have each grammatical errors. But I have no idea how to solve those errors.

I confirmed each original matlab functions work well without GPU.

My environments are below:

Windows 11

Matlab R2023a

CUDA v11.8

Microsoft Visual C++ 2022

NVIDIA GeForce GT710

Thank you.

Hi Yuya,

It looks like the issue is occurring because nvcc is unable to correctly parse the commands in the makefile rather than a syntax issue with the generated CUDA code. I suspect the issue may involve unsupported characters appearing in the path under which you are generating code. I was able to reproduce the "Stray '[' character" error on my end when I tried generating code within a folder having '[' in the name.

Also, I see different paths appearing for each call to nvcc (e.g. "C:\Use", "C:\Users", "C:\U", "C"). Is this something you manually redacted? If not, this could be a bug with nvcc.

Hi Justin

In conclusion, I could solve this error thanks to your advice.

Your comment was precise. Path names you listed (e.g. "C:\Use", "C:\Users", "C:\U", "C") were ones I manually redacted because they included personal information as directory name. And they included Japanese characteres and symbols. So I changed current directory to simply English named one and it worked well.

Eventually I could conduct stereo-vision depth estimation by using NVIDIA GPU.

Thank you.
