在 x64 位機器上的 Visual Studio 2013 中鏈接 tesseract 和 opencv (Linking tesseract and opencv in Visual Studio 2013 on x64 bit machine)
I'm trying to run a program based on tesseract and opencv on Visual Studio 2013. I have a x64 bit machine and the problem is when I run it under Win32 I got only opencv linking errors, however under x64 I got tesseract linking errors.
Here are some errors screenshots :
Tesseract Errors :
error LNK2001: unresolved external symbol pixDestroy
error LNK2001: unresolved external symbol pixReadTesseract
error LNK1120: 7 unresolved externals
Opencv Errors :
error LNK2001: unresolved external symbol _cvLoadImage
error LNK2001: unresolved external symbol _cvCreateImage
error LNK2001: unresolved external symbol _cvSaveImage
error LNK2001: unresolved external symbol _cvReleaseImage
error LNK1120: 4 unresolved externals
Thank you guys :‑)

方法 1:
Your problem appears to be that you have 32bit build of Tesseract and 64bit build of OpenCV, and trying to use them both in the same program. That will not work ‑‑ you either need all 64bit libraries for a 64bit application, or all 32bit libraries for a 32bit application.
If you want to stick with OpenCV 3.1 (since the standard distribution package doesn't seem to contain 32bit binaries), then you have to go and build one of the libraries yourself. The older versions still had them.
Another option is to download this nuget package along with the associated redistributables package. Since the files are just ZIP files with a different extension, it is possible to extract all the headers, import libraries and DLLs manually.
