[Graph program] opencv两个常见的编译错误

Description:

在利用opencv库进行编程中两个常见的问题的解决方法，十分有效！

以openCV的使用为例,并结合个实验经验,总结一下在使用其它库进行编程时VC环境下编译与链接时经常遇到的两个错误的解决办法.

1.编译错误

问题描述:编译时,出现编译如下编译错误:

fatal error C1083: Cannot open include file: 'cv.h': No such file or directory

意思是找不到语句 #include "cv.h" 的cv.h头文件.

解决办法:在工程环境下,Tools->Options->Directories,在页内Show directories for下拉列表框中选择 Include files,然后在Directories列表框中添加上cv.h的路径,
如:D:\OPENCV\CV\INCLUDE,再编译就能找到cv.h头文件了.

2.链接错误

问题描述:链接时出现如下错误:

Linking...

test.obj : error LNK2001: unresolved external symbol _cvCanny

Debug/cvtest.exe : fatal error LNK1120: 1 unresolved externals

解决办法:明明知道cvCanny函数(_cvCanny是纯C编译生成的目标文件的函数名)的原型说明在文件cv.h中,怎么又出现链接错误呢,可能是静态链接库的问题(可能还有其它的原因),
然后有两各解决办法:(1).通过project->Add to project->Files, 将cv.lib加到工程中(2).①Tools->Options->Directories,Show directories for下拉列表框中
选择 Library files,然后在Directories列表框中添加上cv.lib的路径,如:D:\OPENCV\LIB ② project->settings下的LINK属性页下,在Object/Library modules 的文本框中
加上 cv.lib 后,点击确定.此时链接通过.

 

仅为个人的实验经验,有可能不全面或错误.

[Documents] VC小知识

Description: VC小知识 学习VC＋＋时经常会遇到链接错误LNK2001，该错误非常讨厌，因为对于 编程者来说，最好改的错误莫过于编译错误，而一般说来发生连接错误时， 编译都已通过。产生连接错误的原因非常多，尤其LNK2001错误，常常使人不 明其所以然。如果不深入地学习和理解VC＋＋，要想改正连接错误LNK2001非 常困难。-VC small learning VC++ will always be wrong to link LNK2001 error of the hate, because programmers, the best thing is to change the wrong compiler error and the connection errors generally occur, the compiler have passed. Have connected the wrong reason is very large, especially LNK2001 wrong, and often unknown to these people. If not in-depth study and understanding of Visual C++, in order to correct the wrong connecting LNK2001 very difficult.

Description: 调用directshow出现链接错误，如何解决？ player.obj : error LNK2001: unresolved external symbol _IID_IVideoWindow player.obj : error LNK2001: unresolved external symbol _IID_IMediaControl 这是因为链接器没有找到合适的.lib文件。两种办法： 1、在EVC菜单Tools—options—directories 里把library files的路径重新调整一下。如果你只安装了EVC自带的 Standard SDK而没有其它SDK，可以指定WINCE目录中的.lib文件路径，例如D:\WINCE500\PUBLIC\DIRECTX\ OAK\LIB\X86\RETAIL。注意CPU的类型。 2、安装SDK，前提是导出SDK的PB内核工程必须包括DirectShow或者其它组件。 -Call directshow link errors, how to solve? player.obj: error LNK2001: unresolved external symbol _IID_IVideoWindow player.obj: error LNK2001: unresolved external symbol _IID_IMediaControl This is because the linker does not find suitable. lib file. In two ways: 1, in the EVC menu Tools-options-directories in the path of the library files to re-adjust. If you only installed the Standard SDK EVC own and not the other SDK, you can specify the directory in WINCE. Lib file path, for example D: \ WINCE500 \ PUBLIC \ DIRECTX \ OAK \ LIB \ X86 \ RETAIL. Note CPU type. 2, the installation of SDK, SDK, provided that the PB cores derived works must include the DirectShow or other components.
