# Manual Build - Environment Information

*OpenCV version* (example 3.4.1): opencv-4.1.0

*With OpenCV-contrib?* (extra modules): no

*OS*: Ubuntu 18.04

Start with the node-gyp rebuild command and inspect cc/opencv4nodejs.cc, cc/machinelearning/machinelearning.h, and the configured OpenCV include and library paths. Reproduce the install on Ubuntu 18.04 with OpenCV 4.1.0, then determine why /usr/local/include/opencv2/ml.hpp is selected and confirm that the package builds successfully.
