Did you reboot the machine after you added the path? |
|
Yes, I did. I was just reading through others, and I feel like I'm missing something.
I don't have the |

Found it. I opened it with a notepad. I'm not sure how to remove @echo off

|
okay, well that help to clean it. But I'm still getting an invalid mex file. I reboot and did everything again, still doesn't work. |
|
@ramin0711: Also you might wanna use a tool like Dependency Walker on the MEX-files to confirm that all the dependencies are present on the path. btw, double check that you added |
|
I double checked the path, I have the bin. I'm not sure how to use the Dependency Walker to check Mex-files. Here's the first two lines, |
|
Sorry but i must ask again if you are sure about the Plus what exactly is the error message? If its something like:
it usually means a missing DLL file in your system path (OpenCV DLLs in this case) To use "dependeny walker", just download the tool, run it, and open one of the compiled MEX-files |
|
Gotcha, I forgot to add the bin here, but I did add it to system path. the error I'm getting is this, When I want to do the |
|
I redid everything again, matlab crashes every time I run my code |
|
ok then, that error message doesn't look like a compilation or PATH issue.. It appears to be originating from this line I'm guessing you are running the |
|
I have the xml file in the same folder, it was complaining about the mex function, now it just crash. Do I have to change D_SECURE_SCL=0 to one or just leave it? Any suspicions on why it crashes? |
|
It shouldn't be necessary for you to manually change the Now I'm not sure why MATLAB crashes, but it should create a dump/log file after any crash (possibly in the Other than that, I really don't know what's wrong in your case :) |
|
Here's the thing, I change the _SECURE_SCL to 1, and matlab crashed, I turn it back to what it was and |
|
Can you post the output of the following? |
|
Sure, it's |
|
Umm, that looks normal. Did you try any other function than |
|
Okay, I used im = imread('C34.jpg');
gr = cv.cvtColor(im, 'RGB2GRAY');and here is the error. In order to get it to crash, I have to change it |
|
I try this one as well, camera = cv.VideoCapture();
pause(2);The camera turn on with no error. |
|
@ramin0711 : I just submitted a PR that was merged. Retrieve the latest changes, recompile, and run |
|
Okay, I replace the mexopencv folder with the updated version on the web ( is that what you wanted me to do?), so I did everything again, and here's the result to |
|
@kyamagu: ok, so it is as expected; When OpenCV was compiled Therefore mexopencv should be compiled with @ramin0711: |
|
Yes, _SECURE_SCL should be set to 1 by default. And, indeed the following error looks like unmatched _SECURE_SCL flag. @ramin0711 If you ever changed _SECURE_SCL in the mexopencv.make file, return it back to 1. And please post the crash report. |
|
Yes, by default VS2010 has the _SECURE_SCL set to 1. That's why we add |
|
@kyamagu: VS2010
VS2008
So since this flag is undefined in both opencv debug/release builds of VS2010, and since mexopencv links against the release builds, we should NOT set it to 1... In my configuration, I never touched the default |
|
@kyamagu I didn't change @amroamroamro here's the result |
|
@amro That's interesting. I can't confirm this yet since I need to Kota |
|
@kyamagu The correct way to override it is by issuing: To make things worse, i think that this is no longer necessary for VS2010 onwards (since release mode defaults to a value of 1). And it only should be considered for prior VS versions. If you want, I will make the necessary changes and submit a pull-request. I will update both README file and make.m |
|
@amro Thanks, yes please send me a pull request. |
|
@kyamagu: done. sorry this took me longer than I though... |
|
What did you change exactly? |
|
@ramin0711: I fixed the whole In the mean time, undo any changes you made to |
|
@amroamroamro I appreciate! @ramin0711 If you think you messed up the |
|
@amroamroamro Thanks amro, it's working now. Although, one problem I have is that whenever I run one of the matlab files it works fine the first time, but crashes the second time. Thanks for taking the time to help me out. |
|
@ramin0711: i don't know, hard to say without debugging it.. Can you post the crash report, MATLAB should create files named like |
|
It's not big deal, I can live with it. It seems like when I use the camera, if I want to I run the code again, I have to delete the camera from variable list manually, if I use clear all or anything else matlab crashes, I don't know if there's any other easier way to fix the problem. I can send you the crash report, but it's like 12 mb and I can't open the file, how would you like me to send it? |
|
@ramin0711: sorry for the late reply. Are you still experiencing crashes with this? If so you should look for the text crash report (dont need the binary dump file).. |
|
I have the same problem, matlab crashes the second time I run the program. I am using mexopencv in Ubuntu 12.04 with Opencv 2.4.1. Here is the matlab crash dump file: Please help me with this big problem because i am using it for my license project and i need it to work not just one time. Thank you! |

@lidiadunareanu Your issue is not the same. See this to fix. |

I saw a lot of people had a similar issue, didn't help me though. I'm running a Matlab R2012a 64 bit on a 64 bit windows, with sdk 7.1 and VS10. I added the system path,
C:\opencv\build\x64\vc10I downloaded the mexopencv from the website, they talk about making something from opencv, but I'm not sure what they're talking about. All I did, downloaded opencv and mexopencv, run
make.mexopencvon matlab. It seems okay, but when I try using one of the functions it doesn't work. what steps am I missing?Thanks
