This is a protocoll of my (Robert's) attempts to come up with a headless version
|
||
|
|
of Subsurface that runs on a small one chip computer like a RaspberryPi or C.H.I.P.
|
||
|
|
|
||
|
|
The idea behind this is that that computer could do the talking to the dive computer
|
||
|
|
and then provide the data (I thought the easiest way would be via being a wifi
|
||
|
|
access point running a git server serving the user's divelog in git).
|
||
|
|
|
||
|
|
This is still very far from working and a lot more needs to be done. As this task is
|
||
|
|
mainly SysAdmin stuff on the small computer, it's hard to preserve this. So I decided
|
||
|
|
to take a log of what I did. This is a dump of the corresponding wiki page on the old
|
||
|
|
trac system.

* Bought RPi3 with SD card.
|
||
|
|
* Downloaded Raspian Jessie from https://www.raspberrypi.org/downloads/raspbian/ and decompress it
|
||
|
|
* Downloaded PiFiller and run it, follow instructions there
|
||
|
|
* Give up as RPi 3 wants a micro SD card, not an SD card.
|
||
|
|
* Reinstalled on a micro SD
|
||
|
|
* Connected network cable from Laptop (enabled Internet sharing in System Preferences)
|
||
|
|
* ifconfig suggests RPi got IP address 192.168.2.2
|
||
|
|
* logged in as user pi and pw raspberry
|
||
|
|
* sudo apt-get update and upgrade
|
||
|
|
* no space left on device. Hmm. Trying to reboot
|
||
|
|
* ah running sudo rasps-config allows to extend the file system
|
||
|
|
* sudo dpkg-reconfigure tzdata
|
||
|
|
* mkdir src
|
||
|
|
* cd src
|
||
|
|
* git clone git://subsurface-divelog.org/subsurface.git
|
||

* subsurface/scripts/build.sh
|
||
|
|
* fails to find an include file, trying export QtDir=/usr/include/i386-linux-gnu/qt5
|
||
|
|
* that did not help, now trying CPATH
|
||
|
|
* Argh, of course, it's not i386-linux-gnu but arm...
|
||
|
|
* Now, it complains about qt wanting fPIC for position independent code. Setting that in CMakeText
|
||
|
|
* Ah, no, that is just for some test. The subsurface binary is already built. good.
|
||
|
|
* And it starts (after I have installed XQuartz on my Macbook)
|
||
|
|
* after initial problems (I don't know), it downloads dives from the Vytec.
|
||
|
|
* I created a new directory and do git init there and then I can save in git format
|
||
|
|
* From the laptop: git clone ssh://pi@192.168.2.2/home/pi/.subsurface/gitsave works
|

==RPi as wifi access point==
|
||
|
|
* sudo apt-get install hosted
|
||
|
|
* Following https://www.elektronik-kompendium.de/sites/raspberry-pi/2002171.htm
|
||
|
|
* sudo vi /etc/hostapd/hostapd.conf
|
||
|
|
* sudo chmod 600 /etc/hostapd/hostapd.conf
|
||
|
|
* sudo hostapd -dd /etc/hostapd/hostapd.conf
|
||
|
|
* I see the AP but my passphrase is rejected. Now trying http://elinux.org/RPI-Wireless-Hotspot
|
||
|
|
* sudo apt-get install udhcpd
|
||
|
|
* sudo vi /etc/udhcpd.conf
|
||
|
|
* sudo vi /etc/default/udhcpd
|
||
|
|
* once more sudo vi /etc/hostapd/hostapd.conf
|
||
|
|
* reboot
|
||
|
|
* one day later: I have to do the sudo ifconfig wlan0 192.168.42.1 again, but then it works. The iPhone take the connection and sees 192.168.42.1
|
||
|
|
|
||
|
|
* sudo apt-get install apache2
|
||
|
|
|
||
|
|
== Installing the command line version of subsurface ==
|
||
|
|
|
||
|
|
* cd ~/src/subsurface
|
||
|
|
* mv build build.full
|
||
|
|
* git remote add github https://github.com/atdotde/subsurface.git
|
||
|
|
* git checkout github/command_line -b command_line
|
||
|
|
* cd ~/src
|
||
|
|
* subsurface/scripts/build.sh
|
||
|
|
|
||
|
|
|
||
|
|
==BIND==
|
||
|
|
* sudo apt-get install bind9 bind9utils dnsutils
|
||
|
|
* sudo vim /etc/bind/named.conf.local
|
||
|
|
* sudo vi /etc/bind/db.example.com
|
||
|
|
|
||
|
|
==Git server on CHIP==
|
||
|
|
So far, no significant difference to the Pi
|
||
|
|
|

|
|

|
* sudo vi /etc/gitweb.conf
|

|
||
|
|
==a new attempt==
|
||
|
|
* threw away the default site and roughly followed http://p0l0.binware.org/index.php/2011/08/26/git-over-http-git-http-backend/ (without SSL or authentication)
|
||
|
|
* /etc/apache2/sites-enabled/001-git.conf
|
||
|
|
* created /var/www/git/test.git as a repository and gave rights to www-data
|
||
|
|
* git config http.receivepack true
|
||
|
|
* this seems to work as in serves git repository clone and push
