I tried to create simple app which will connect to deezer and play single song. I got access token and wrote this program. Target machine: linux x86_64 API version: v1.0.1 Suddenly i ran into problems. First run shows me this output: 398748:201417 dz_bufferevent: [dz_bufferevent_on_activation:561] could not open /var/tmp/settings.dat I created this file, but I suspect that it shouldn’t be empty.
