win8 Pro+ matlab2013a+VS2012( or VS2010) : Invalid MEX-file, ..., specified module could not be found

[yreme]

Hi, I came across an issue :

    Invalid MEX-file, ..., specified module could not be found 

similiar with #58 , #76

opencv run well in VS, but meet trouble in matlab

My OS environment is win8 Pro x64 + matlab2013a, I have try those

1. mex -setup with VS2012 or VS2010 , and '/D_SECURE_SCL=0' or '/D_SECURE_SCL=1' in make.m , but helpless. My VS2012 could successfully run opencv2.4.8

    if isVS && (str2double(c.Version) < 10 || opts.debug)
        comp_flags{end+1} = '/D_SECURE_SCL=1';
        fprintf('[if] D_SECURE_SCL  %s\n','/D_SECURE_SCL=1');
        %VS2010 and newer: In debug mode, the default value for _SECURE_SCL is 1. In release mode, the default value for _SECURE_SCL is 0.
    else
        %comp_flags{end+1} = '/D_SECURE_SCL=1';
        fprintf('[else] D_SECURE_SCL  %s\n','/D_SECURE_SCL=0');
        %VS2010 In debug mode, the default value for SECURESCL is 1, .... In release mode, the default value for SECURESCL is 0.


        comp_flags{end+1} = '/D_SECURE_SCL=0';
    end

2. It is noticable such problem also occurs at opencv's matlab modual in my PC. They could be complied, but error with :

      Invalid MEX-file, ..., specified module could not be found 

DLL with Dependency Walker

Besides, with Dependency Walker on the MEX-files (GaussianBlur mexfiles) , I found such dll are relatived,

API-MS-WIN-CORE-SYNCH-L1-1-0.DLL
SHCORE.DLL
SHLWAPI.DLL
EXT-MS-WIN-ADVAPI32-PSM-APP-L1-1-0.DLL
EXT-MS-WIN-NTUSER-MESSAGE-L1-1-0.DLL
IEFRAME.DLL

indeed most of those could be found in the path:

     windows/system32

It seems they are all right.

Where do you install OpenCV? You have to set up a system PATH variable pointing to the correct OpenCV location. Check README.

[yreme]

my opencv dll path is：

D:\opensource\opencv\opencv2.4.8\opencv\build\x64\vc11\bin

so in the system path:

%opencv248%\x64\vc11\bin;%opencv248%\x64\vc10\bin;

where

opencv248=D:\opensource\opencv\opencv2.4.8\opencv\build

Is there any other solution that might concern windows 8?

Are you sure your Matlab is 64-bit? Matlab for both 32-bit and 64-bit can be installed in win64 environment.

[yreme]

this matlab is 64bit. I install this matlab and mexopencv on another x64
win7 computer , it works. so I donot known what is the trouble in win8.

Then I don't know. It can be you're not rebooting the OS for a PATH to take effect. What I can tell is that the error message says that OpenCV dll's are not in the PATH. Check again any typos, etc.

[yreme]

Thanks, your are all right! The problem was solved by directly adding opencv dll path

D:\opensource\opencv\opencv2.4.8\opencv\build\x64\vc11\bin

rather than set user variable opencv248=D:\opensource\opencv\opencv2.4.8\opencv\build .
