No suitable constructor exists to convert from "int" to "CvSlice" #15

Open ChinJoshi opened 6 years ago

ChinJoshi commented 6 years ago

When building the library, I am getting an error that is quite puzzling. The error is saying No suitable constructor exists to convert from "int" to "CvSlice". I have built opencv 3.4 with CUDA and contrib modules successfully with no errors as well as eigen 3.3 and pangolin. Any help at all would be greatly appreciated.

Here is the console output:

I am using Ubuntu 14.04 and OpenCV 3.4.3, and I had the same compilation error for a different software project (see stackoverflow.com/q/52360984/896495). My error looks like this:

/media/truecrypt1/workspaces/cpp/src/opencv/modules/core/include/opencv2/core/types_c.h(1359): error: no suitable constructor exists to convert from "int" to "CvSlice"

I am using Ubuntu 14.04 and OpenCV 3.4.3. My solution to this problem: check in your cuda code (.cu files) which #include preprocessor directive is adding an OpenCV header. Then somehow modify your code to avoid that the said header is included into in your cuda code (.cu files).
