Installation
Do not stray from or vary these instructions. If you don't do it all, in precisely the right order, with zero mistakes, it's not going to work. Copy & Paste will be your friend.
You need to be logged in as root with a writeable filesystem. Instructions for both those things can be found elsewhere on this wiki.
The first time you install accelservice you must do all these steps:
<source lang="text"> mkdir -p /var/etc/ipkg/ ln -s /etc/ipkg/arch.conf /var/etc/ipkg/ echo "src/gz all http://ipkg.preware.org/feeds/preware/all" > /var/etc/ipkg/preware.conf </source>
- If you are on the Pre, type:
<source lang="text"> echo "src/gz armv7 http://ipkg.preware.org/feeds/preware/armv7" >> /var/etc/ipkg/preware.conf </source>
- If you are on the Emulator, type:
<source lang="text"> echo "src/gz i686 http://ipkg.preware.org/feeds/preware/i686" >> /var/etc/ipkg/preware.conf </source>
Then type:
<source lang="text"> /usr/bin/ipkg -o /var update /usr/bin/ipkg -o /var install org.webosinternals.accelservice /bin/sh /var/usr/lib/ipkg/info/org.webosinternals.accelservice.postinst /usr/bin/ipkg -o /var install org.webosinternals.accelexample </source>
Then restart the GUI service to pick up the new service:
<source lang="text"> initctl stop LunaSysMgr && initctl start LunaSysMgr </source>
If the above fails to show the results you're expecting, reboot the device.
Updating
After your first install, only the following is required to upgrade to a new version.
You need to be logged in as root with a writeable filesystem. Instructions for both those things can be found elsewhere on this wiki.
From a shell:
<source lang="text"> /usr/bin/ipkg -o /var update /usr/bin/ipkg -o /var upgrade reboot </source>
Other PreWare Applications
You need to be logged in as root with a writeable filesystem. Instructions for both those things can be found elsewhere on this wiki.
Note that you can use the same commands to install other applications from PreWare:
<source lang="text"> /usr/bin/ipkg -o /var update /usr/bin/ipkg -o /var list /usr/bin/ipkg -o /var install <package> # choose a package from the list /usr/bin/ipkg -o /var remove <package> </source>
Removal
You need to be logged in as root with a writeable filesystem. Instructions for both those things can be found elsewhere on this wiki.
<source lang="text"> /usr/bin/ipkg -o /var remove org.webosinternals.accelexample /usr/bin/ipkg -o /var remove org.webosinternals.accelservice </source>
Then restart the GUI service:
<source lang="text"> initctl stop LunaSysMgr && initctl start LunaSysMgr </source>
If the above fails to show the results you're expecting, reboot the device.
