Error in header files. about cardetect

[skandhurkat]

Hi,

I don't see any files in the report. Could you write the file names again? Also, where are these files referenced.

Thanks.

Hi Skandhurat,

Sorry, I forget to mention the header file names.

Please find below the mentioned header files. I am using OpenCV 2.4.5 version, but I don't think the below mentioned problem is related with Opencv.

#include "thread"
#include "mutex"
#include "getopt.h"

Due to the above files, there are errors occurring in the program. Please guide me where to find the above mentioned file. I have downloaded you source code an exactly uploaded in visual studio. But there are errors due to above file.

Errors:

1. error C2668: 'ceil' : ambiguous call to overloaded function
2. error C1083: Cannot open include file: 'thread': No such file or directory

"thread" and "mutex" are part of the C++11 standard. To use these files, you'll need GCC >= 4.7, or MS Visual Studio > 2010 (I believe). The last time I checked, MingW did not support threads on Windows. You can go to the Woe32 branch for an older version that uses Win32 threads instead of C++11 threads.
"getopt.h" is used for parsing input arguments, and the only place it's used is in the main() function. Getopt is the standard way to parse input arguments, and provides a very clean interface, which is perhaps why VS does not support it. :)
I think that there are some ports for getopt for Visual Studio, otherwise, you can delete the getopt related code in main(), and write your own argument parsing routine.

Hi Skand,

The problem for getopt.h header file is solved but I am still confused with the above explanation because I am new towards C++. Could you tell me some steps what to do with the rest of two files mutex and thread. Sorry, for my silly questions.

[skandhurkat]

Let's go through this step by step:

1. What compiler are you using
2. What's the version
3. What steps did you use to solve the getopt.h problem.

[RickVedrine]

C++. I am using Visual Studio 2010. I searched out for getopt.h and found downloadable header file.

[skandhurkat]

Please use the files from the Woe32 branch. I haven't built a CMake build system for that branch yet, but you should be able to just replace files from Woe32 into master.

[RickVedrine]

Alright, let me give a try.

[RickVedrine]

I tried editing the code but in vain.

[skandhurkat]

I am leaving this issue open. Will try to issue a fix over this weekend.

[skandhurkat]

Fixed the Woe32 branch to use CMake. I've also added another project getopt-for-Visual-Studio. Try compiling the Woe32 branch again.

Let me know if this fixes the issues you've been having.

Closing issue because there has been no activity for a month.
