Because I’m not able to add the correct paths inside the right config file,I tried to run a precompiled version of blender 2.82 and I tried to install and enable the open pose addon. I wanted to do an attempt,anyway,maybe I’d been lucky). This is the error that has been shown :
ERROR: flag ‘logtostderr’ was defined more than once (in files ‘/build/blender-fMrWhw/blender-91562-b5244cd5dc1/extern/glog/src/logging.cc’ and ‘src/logging.cc’).
