|Building SWI-Prolog on Android using LinuxOnAndroid|
This page describes the using LinuxOnAndroid, which provides a complete Linux userland on your Android device running in a chroot environment alongside Android. The installation requires rooting your device.
This procedure was tested on a Samsung GT-P5110 (Tab 2 10.1) running Android 4.1.2.
I used LinuxOnAndroid. This first requires you to root your device, which took most of the time. Of course, all the usual `at your own risk' applies. I installed Ubuntu 12.10.
This is very similar a normal build on Debian/Ubuntu. I left out JPL (Java), ODBC, ssl and utf8proc, but I see no reason why this would fail.
The Ubuntu image itself is rather full (although it will fit). Using the
external sdcard will not work because it is formatted
as FAT32 and mounted with the
noexec flag. If you have enough space,
use a directory on the internal sdcard. Else, what I did, was to make
2 partitions on the external sdcard. The first is a FAT32 one that will
be used by Android. The second can be formatted with a Linux filesystem
and mounted. This is the easiest way to get more Linux native space that
I could find as it does not require any changes to the Android system
P.s. With the above packages stripped and without C debug symbols, you need about 300Mb free space.
There should be no issues building 6.4.x or 6.5.x. Just follow the standard
procedure. You can set
MAKE=make --jobs=2 to use the two cores of your
With an external mouse and keyboard, it works quite ok. Speed on CHAT80 is about 1 million inferences/sec, or about 1/8 of my Intel i7 desktop. You can run the HTTP services and thus develop HTML5 apps that run entirely on your Android. I think this should work on any device on which you can install Linux alongside Android.
