Hi @jinfagang Did you follow the instructions from that post DGM for Ubuntu ? In particular did you use the following string for CMake? cmake .. -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local

lucasjinreal commented 5 years ago

@ereator I tried, but nothing help with trigger the release option

ereator commented 5 years ago

@jinfagang I have tested with Ubuntu 18.04, OpenCV 3.3.0 and the latest DGM 1.7.0 from master and can't reproduce the error.

Hi @jinfagang, starting from the release 1.7.0 the DGM library officially supports Linux. In particular it was tested with Ubuntu 18.04 and gcc 7.3.0. Please refer to the Installation Guide for more details.
