spams tool for image processing -- compiling error

Hello

I am muthana from Iraq. I have some questions about a spams tool that calls a c++ lib from MATLAB.

MATLAB does not execute to the end of the compile program. Why not?

For whatever reason it is expecting a file or directory named "Files" inside your current directory, but is not finding it. We cannot tell from the screenshot whether you have such a file or directory name.

I suspect that you have a directory that starts with 'Files' and then has a space in it, and that the command that was given to mex failed to put quote marks around the directory name. mex normally considers spaces to be the end of the option or file name.

please tell me what do you mean by (files) ican not find it

You see the first error message in red? It talks about D:\projectresearch2\matlabworks\spamlibrary\spammatlab\Files not found. Your title line shows that you have D:\projectresearch2\matlabworks\spamlibrary\spammatlab as your current directory, so it is looking for something named Files within your current directory and it is not finding it.

I cannot tell from the screenshot what command you gave to MATLAB.

As I look at the source code at https://github.com/AllenXL/Image_Video_Processing-Matlab/blob/master/My-Matlab-Toolbox/spams-matlab-v2.3-svn2013-06-20/spams-matlab/compile.m I see a potential bug. I also notice that is not the version you are using (the line numbers do not match), which leads me to notice that you are not using the latest version. The latest version is at https://gitlab.inria.fr/thoth/spams-devel and it would probably be better for you to load in that version.

please i run your version but sill not work and the same message error above

[Walter Roberson]

Please attach a copy of the compile.m script with any changes you have made to it.

What is this? What does a spams tool have to do with image processing?

[Walter Roberson]

SPAMS is "Sparse Modeling". The code that appears to be in use seems to be a fork from that called the THOTH project, http://thoth.inrialpes.fr/ "Modeling visual knowledge from large-scale data "

hello iam happy to your comment i hope to solve this by your idea the compiler are in the attachment thannnnnnnnnnnnnnx

[Walter Roberson]

You have configured gcc. The Windows portion of the compile.m says,

        % example when compiler='gcc' for Windows+cygwin:    (the script does not
        % work at the moment in this configuration

so they are not expecting the code to work for some reason.

[muthana naeem]

please tell me what i must do ?how can you help me ?

[muthana naeem]

can help me on how can change 'gcc' to other compiler

[muthana naeem]

my email is [e-mail] can i get your email ?

[Walter Roberson]

If you have visual studios installed, edit the line

compiler='gcc';

to

compiler='vs';

I would not be surprised if you continue to have the same problem, though. I can see what is probably happening, but when I look at the function I do not see quite why it is happening.

[muthana naeem]

very thanks to you but you tell me that not working on windows it ia working on linux are you sure?? i will convert my system to linux is the same matlab version on windows will work on linux ???

[muthana naeem]

ohhh my god all problems are solved in windows i change the gcc to vs it is work on compilation succesfuly but i need help to get more information aboout the result please help me

[muthana naeem]

i have this problem in the end of compile but it start successfully how can solve this

[Walter Roberson]

This turns out to be involved with a messy inconsistency between C and C++. See https://trac.osgeo.org/geos/ticket/34 and http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#456

I speculate that compiling with a new enough VS set to -std=c++11 might possibly work, but I am not at all certain. It might call for a small change to the code to

#include <cctype>
