Of course... I forgot it's not a valid character under windows. Maybe a describtiv error message would be nice, instead of a crash.

Hello everybody!

I was experimenting with cv::VideoWriter a bit today and I noticed something weird. I was trying to build the filename out of a name, the date and the current time. The string was correct, but my program kept crashing. I noticed that the crash was due to the ":" in the date represenation. When ever there is a ":" in the filename string passed to cv::VideoWriter the program crashes.

Can somebody tell me why that is? Or if this may be a bug. Thanks!

The callstack and all the details for the crash on xp are in the other question. The one on Windows 8 (my current machine, the xp is just an older one) behaves pretty much the same way. In debug mode it exits right after launching with a SIGSEGV fault. Here is the call stack: http://pastebin.com/MdnYF86E

The problem appear for both my windows 8 and my windows xp. The including and link works fine, but once I run I get a crash saying 0xc0000142 on wind7 and 0xc0000005 on xp

As I said in my original post, whenever I use the prebuilt libraries I get a runtime error. All the detail are in this question. What do you mean with pdb files? I am using MinGW and Code::Blocks.

Hello everybody!

I have been working with OpenCV before, but I had to switch machines and my version of OpenCV got lost in the process. So I need a new one.

First I tryed to download the latest release for the website, but I got runtime errors, I was unable to solve. See this issue.

I already have some experience compiling librarys on my own, so downloaded the latest source and tryed to compile it myself with MinGW gcc 4.7.2 on my windows 8. I have been trying to do that for the past two days. I ran into a lot of difficulties. For example this issue or that I had to include some files manually and in the end there was a undefined reference I could not resolve.

To make a long story short, I almost ready to give up now. So what I'm asking is if somebody could please be so kind to upload a working install directory (include, lib, bin) of OpenCV 2.4.5 (or the lastest source I don't care) compiled with MinGW gcc 4.7 for windows(I also don't care about TBB or anything, I just want a working copy) so I can finally get my code working again.

I would be extremly thankful, if somebody could help me out here! Thanks in advance Foaly

Hello I just downloaded the latest version 2.4.4 of OpenCV. After some complications at first, I managed to get my little sample program to run (code below). When I try to run the program however it crashes right away. The error code I get is:

The application failed to initialize properly (0xc0000005). Click on OK to terminate the application.

Some more info: I am working on a windows XP machine using Code::Blocks and MinGW (gcc version is 4.7.2) I set up my environment like this:

Oh my god!!! You saved the day! Thank you so much! I am working with Code::Blocks and I clicked Building Target "all" which complied the .dll, but somehow didn't install it. So now I built the "install" Target and it copied everything I need into the install directory! Thanks again!!

Thanks! I already thought about that, but it seems like a bad hack to me, because the prebuilt package is version 2.4.3 and the one from git is 2.4.9 Also I don't get why there are no include files in the source i grabed from git... there has to be!

Hello everybody,

I want to use OpenCV for a project, so I downloaded the precompiled binarys. (Working on Windows 7 with MinGW (gcc 4.7.2)) I installed everything and the sample project I set up compiled fine, but whenever I tried to execute the program I got an unexpected exception 0xc0000005. I played around, but nothing worked. So I thought it might be because the .dlls were compiled with an older version of gcc (maybe 4.6 or something)

So I downloaded the source and set everything up. It took a long while, but it finally compiled. So now I have (hopefully working) .dlls, but as I tried to test them with a sample project, I got the error: "opencv2/core/core_c.h: No such file or directory" when I use #include <opencv2/opencv.hpp> but the include directory from the git repository is definitely included in the project...

I am really lost at this point. I would love to use the precompiled binarys, but I am also willing to compile my own from source. I just need something that works :)

Please help me I would love to use this awesome library! Thanks in advance, Foaly
