Jocelyn (or anybody else interested): I'm currently working on a systemd service file for YACReaderLibraryServer so users don't have to mess with cronjobs anymore. It's already working on my Archlinux machine but it needs testing by actual users so that I can be sure it works as intended. So, if you could test it and give me some feedback that would be appreciated

[Unit]
Description=YACReaderLibrary headless server
After=network.target

[Service]
Type=simple
Restart=always
ExecStart=/usr/bin/YACReaderLibraryServer start

[Install]
WantedBy=multi-user.target

Instructions:

0. create a file named "yacreaderlibraryserver.service" and copy the text above into it
1. change the path used in ExecStart so it points to the location your headless server binary resides
2. copy the service file to ~/.local/share/systemd/user
3. enable the service file by running:
"systemclt --user enable yacreaderlibraryserver"
4. start the server by running:
"systemctl --user start yacreaderlibraryserver"
5. check the server status by running:
systemctl --user status yacreaderlibraryserver

The server will keep running till you tell systemd to stop it by running "systemctl --user stop yacreaderlibraryserver". In the event of a program crash systemd will reload the server. Feel free to test this by running "killall YACReaderLibraryServer". IMPORTANT!!! Never run YACReaderLibraryServer as root!!!

Hi, I'm using a RPi 3 with DietPi v158 (jessie based).

It has not ~/.local/share/systemd/user, so I put your .service in /etc/systemd/system

When launching YACReaderLibrary from cli or from crontab, it's launched from root user, so it uses ~/.local/share/YACReader/YACReaderLibrary/ for log and configuration .ini file

When launching with systemctl, it uses /.local/share/YACReader/YACReaderLibrary/ directly from / (root folder), so no library configured. After I have copied my original .ini to this new location, it works fine and I have again my library accesbible, but using service rather than crontab.

You gain literally nothing by doing so except a potential security risk. If ~/.local/share/systemd/user is missing you just can create it - systemd should be able to detect it. Otherwise I'm happy to hear that this works for you

*** Nevermind, a reboot fixed the issue ***

When i try to run the command: "hg clone bitbucket.org/luisangelsm/yacreader ." i get the following error.
Any idea as to what could cause this?
I'm using a Raspberry Pi 3 running the latest Stretch.

Ok I think I found the problem. The unarr detection for the embedded build is broken.

Open compressed_archive/unarr/unarr-wrapper.pri and replace this:

unix:!macx {
    !contains(QT_CONFIG, no-pkg-config):packagesExist(libunarr) {
      message(Using system provided unarr installation found by pkg-config.)
      CONFIG += link_pkgconfig
      PKGCONFIG += libunarr
      DEFINES += use_unarr
      }
    else:exists(/usr/include/unarr.h) {
      message(Using system provided unarr installation.)
      LIBS += -lunarr
      DEFINES += use_unarr
    }
  }

With this:

unix:!macx:!contains(QT_CONFIG, no-pkg-config):packagesExist(libunarr) {
    message(Using system provided unarr installation found by pkg-config.)
    CONFIG += link_pkgconfig
    PKGCONFIG += libunarr
    DEFINES += use_unarr
  }
else:unix:!macx:exists(/usr/include/unarr.h) {
    message(Using system provided unarr installation.)
    LIBS += -lunarr
    DEFINES += use_unarr
  }

Save it, run "make distclean" to clean the old build files and restart the build at the point where you run qmake. If everything went right qmake should display a message that it found unarr.
