import ofxCv.h give error: ‘cv::Size2d’ has not been declared

I'm using the last version of master branch of openFramework and the last version of develop branch of ofxCv.
I'm using GNU Make 3.81 under linux Mint 17.1 64bit.

Compiling the project "example-face" give me these errors:

I'm getting this error, too.
~~I assume the develop branch uses OpenCv 3. There is no typedef for Size2d in opencv2, only Size2f.~~

In my case it has to do with the cmake base build system for of: http://github.com/ofnode/of
The build System uses the header files of the Operating System instead of the openFramework provided ones. And the Size2d is not declared in there.

If one of you can push a PR that swaps Point2d for Point2f and fixes this,
I'm happy to merge it!

Is this a good solution? I would assume that you used double precision because you needed it in these cases.

Kyle McDonald · Answer 5 · Thu Oct 29 2015 22:29:31 GMT+0800 (China Standard Time)

@aspeteRakete i used double because i was following examples from other folks. looking at what the data is actually used for, i think it's fine as single precision.
