error C1083 cannot open eigen/core
I download a source code from internet. There is no instruction on developing this code except that it said it uses Microsoft visual studio and opencv 2.1. Then I found in the additional include file consist of file from Eigen 2.0.17. So I install it and include it in the project. However there are errors as stated above. How should I use this Eigen thing in this project?
if you find code, which requires opencv2.1, that must be very, very, very, very old.
(maybe it's not useful any more)
then, - how should we know, without knowing, what you're talking about, how you installed it, etc ?
ya.. it seems like I have to rebuild the code. Because there is another error occur. can you take a look here http://answers.opencv.org/question/92594/error-c2665-regarding-imshow/@berak
It means that the Eigen library is not installed on your system and thus the code is depending on it. Install Eigen and even better, recompile the code using OpenCV 2.4 or 3.0!
BTW any guide to recompile this code? Any tutorial, or something to read so I can rebuild it?
not unless you tell us what you're trying to compile ...
"I download a source code from internet." - lol, really ?
I just need something that can help me convert the old version to the new one.
the old version of what , again ? you never told us.
opencv2.1 to opencv3.1
