node-opencv 4.0.0 does not build against OpenCV 3.1.0 with GCC 5.2.0 #355
Description
When I try to build node-opencv 4.0.0 (actually the latest "master" form Github) against OpenCV 3.1.0 I get the following errors under GCC 5.2.0:
> [email protected] install /u/rse/prj/opencv/node-opencv
> node-pre-gyp install --fallback-to-build
gmake: Entering directory '/u/rse/prj/opencv/node-opencv/build'

Before digging deeper, the questions for me now are:
- Is node-opencv intended to be built against OpenCV 3 at all?
- If (1) is "yes", is just the latest OpenCV 3.1.0 the problem?
- If (1) is "yes", is perhaps the GCC 5.2 and its strictness here the problem?
Has anybody successfully built node-opencv against OpenCV 3?
