Question

我是开放世界大事。

我刚刚安装了开放式电脑,使C++方案成为下文。

我的编辑是视觉C++。

# include "highgui.h"
void main() {
  IplImage* img = cvLoadImage("C:/OpenCV/samples/cpp/tutorial_code/images/lena.png",-1);
  cvNamedWindow("lena",0);
  cvShowImage("lena",image);
  cvWaitKey(0);
  cvReleaseImage(&image);
}

但这不能用错误的信息来加以构建,我无法解决这一问题。

错误信息如下。

(My compiler is Korean Version and I translate the error message into English. And the English is poor, but you may understand how it was processed.)

我修改了视像仪++环境如下。

在“包括名录”条目中,我投入了“(OPENCV_DIR)”。

and make the “Additional Dependencies” entry to include the next .lib file as the OpenCV Tutorials Release 2.3 guides.

‘opencv_core231d.lib’
‘opencv__imgproc231d.lib’
‘opencv__highgui231d.lib’
‘opencv__ml231d.lib’
‘opencv__video231d.lib’
‘opencv__features2d231d.lib’
‘opencv__calib3d231d.lib’
‘opencv__objdetect231d.lib’
‘opencv__contrib231d.lib’
‘opencv__legacy231d.lib’
‘opencv__flann231d.lib’

视像仪++环境的图书馆名录也作如下修改。

图书馆:

$(VSInstallDir)lib
$(VSInstallDir)
$(FrameworkSDKDir)lib
$(WindowsSdkDir)lib
$(VCInstallDir)atlmfclibi386
$(VCInstallDir)atlmfclib

C:opencvuildx64vc10lib // modified

包括:

Answer 1

It s seems that your processor can t recognize the user vairble OPEN_CV first, make sure that the systemuser vairble is correct. in order to do that go to system properties --> on advance menu --> to go Enviroment variables --> make sure your system variable is correct , if not please create one with the path to your open cv library location.

“用户变量”/

it s seems like you are doing everything right , I believe your problem is that you have missed some at the post build step ...

Second , you ll have to copy the dll files from the openCV library to the location of your project. in order to do so , please include an appropriate path on the post build step on your project. go to your project : properties ... watch the picture here

包括指挥:

copy "C:OpenCV2.31CMake_BuildinDebug*.dll"
copy "C:OpenCV2.31CMake_BuildinDebug*.pdb"

Answer 2

Basically it seems, that the compiler cannot find the OpenCV libraries or has trouble identifying the right one.

确保所需图书馆(即<条码>开放cv__xxx.lib) 可在图书馆名录中注明的名录上查找(C: opencvuildx86vc10lib等)。此外,你应仅具体说明您的平台的名录,即只有<代码>vc9。 (自您重新使用VS2008)和x<86/code>/x64,视您的结构而定。

PRJ0018 press indicated, that thecode>OPENCV_DIR environment/2007/5 is not set out. 您可以在系统房地产诊断中这样做(通常是通过在Win7/Vista的“My Computer”上进行右翼测量和选择“Properties”,你必须到“Ex 预期系统环境”上,在Button有“环境变量”。但是,如果你已经修改了这些名录,你可以放弃“包括名录”的设置。

它可以帮助你。

采用“开放社区”模式2.1 , 采用“管理视觉”;

开放CV 2.1.0版,《2008年视觉》()。
