OpenCV 2.2 install guide

[bartlunatyk]

Thank you very much!! I had so many problems configuring this library!! Great work!

[SmartLabRat]

Best Installation tutorial ever!!

[manikumar510]

Thanks a lot man.

I was trying to install that from last one week.

your video make's me clear...............

But one thing, while installing OPEN CV 2.2 You have select 'Add Path to current user.'

[aaborkar]

Thanks! This video definitely made all the dependency handling a whole lot easier.

A small suggestion, you could add pre-build events to copy either debug/release dlls into the working path before compilation.

Could you make a video how to install and use JavaCV. I'm trying to do it for two days but it's no use. There are many people suffering when installing JavaCV, absolutely noobs like me.

I had an error "22>LINK : fatal error LNK1104: cannot open file 'python26_d.lib'". How to correct this? Thanks

[MrAntiDanti]

@emeanyack

Start all over again! there went something terrible wrong! (but first check your linker settings!)

[emeanyack]

@MrAntiDanti, I googled for the error and find that it's because of python header file. Therefore, I unchecked pyhton settings which solved my problem. By the way, thanks for the tutorial

[bbyrne1able]

Thanks very much. Eventually got it done :-)

[Seadtr]

I get error :

Cannot open include file: 'opencv2/core/core_c.h': No such file or directory

Pls, help???

[MrAntiDanti]

@Seadtr

For basic openCv functions you don't have to include "core_c.h"; (for fist test i recommend only basic functions!)

if you wont to use improved opencv functions (exg. camShift) you have to include "opencv.hpp" and add "(OpenCvIncludeDir)\opencv2" to additional include dir's and link the used functions libs and bins.

I am getting the error:

LINK : fatal error LNK1104: cannot open file 'highgui210d.lib'

[MrAntiDanti]

@bbyrne1able

you use the wrong version of openCv! u have to use 'highgui220d.lib' not 210!

or u simply mistype! check linker settings!

[bbyrne1able]

@MrAntiDanti Thanks very, dont know how I managed to do that.

[Pavtsa]

I dont have that visual studio file in my build folder after using cmake. what are you clicking? what do I open in visual studio?

[MrAntiDanti]

@Pavtsa the compiler exe should by in ""C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe""

[TheZoobiscuit]

hey! erm how exactly do you install cmake?..

[b1lal123456789]

hi there

great stuff. done everything but cant see the source code you are writing. can you copy paste it here

thx

[Thrashmetalman]

Is there a better quality video somewhere or written instruction because I can only make out half of what is being done...

[tobiaspahlberg]

Hi, I'm totally new to C++ and OpenCV.

I get an error at the imread-line: cv::Mat img - cv::imread("myFilePath");

error C2143: syntax error : missing ';' before '-'

[MrAntiDanti]

@tobiaspahlberg cv::Mat img = cv::imread("myFilePath"); you have to use "=" not "-"

[tobiaspahlberg]

@MrAntiDanti Thanks, of course... that worked much better. Though I still can't see that it's an "=" even in 1080p ;)

[Kanyanisback]

Thanks you so much ! You saved me hours !

[gebspsg]

hey thanks for the great video..i did everything exactly as u guys said but i still got the following error.....while running the program..the program builds successfully..

Unhandled exception at 0x7635b727 in helloworld.exe: Microsoft C++ exception: cv::Exception at memory location 0x003deb74

[MrAntiDanti]

@gebspsg: Hard to say! When you compile to code there are no errors?! Make sure that you copy the right binary Files. Do not take the Original binary’s you have to use the C-Make generated Files! I don’t know if the developers fix the C-Make list (warning during building). If so there should be generated header files, then use them.

[gebspsg]

@MrAntiDanti thanks for the info. I fixed it....and great video! it was really helpful!! thanks!!!

[2050ae]

@gebspsg I also got exactly the same error.Did you got the correct solution after that?Please help.

[MrAntiDanti]

@2050ae Check if you set up correctly the Debug and Release settings. When you use Debug (e.g. opencv_core220d.lib) LIB's and BIN's in the Release compile mode this may cause such an error.

Check all your VS settings (C/C++, Linkers and Prebuild)
