KOReader is a document viewer application, originally created for Kindle
|
2015-10-06 14:14:26 +00:00
|
|
|
e-ink readers. It currently runs on Kindle, Kobo, PocketBook, Ubuntu Touch
|
|
|
|
and Android (2.3+) devices. Developers can also run Koreader emulator
|
|
|
|
for development purpose on desktop PC with Linux and Windows operating system.

Building Prerequisites

These instructions for how to get and compile the source are intended for a Linux
|
2014-05-29 13:09:22 +00:00
|
|
|
OS. Windows users are suggested to develop in a [Linux VM][linux-vm] or use Wubi.
|
2013-03-24 14:08:42 +00:00
|
|
|
|
2015-08-02 18:09:54 +00:00
|
|
|
To get and compile the source you must have `patch`, `wget`, `unzip`, `git`,
|
2015-10-06 14:14:26 +00:00
|
|
|
`cmake` and `luarocks` installed, as well as a version of `autoconf`
|
2015-08-02 18:09:54 +00:00
|
|
|
greater than 2.64. You also need `nasm` and of course a compiler like `gcc`
|
|
|
|
or `clang`. If you want to cross-compile for other architectures, you need a proper
|
|
|
|
cross-compile toolchain. Your GCC should be at least of version 4.7 for both native
|
|
|
|
and cross compiling.

Users of Debian and Ubuntu can install the required packages using:
|
2014-03-25 14:26:36 +00:00
|
|
|
```
|
2015-10-06 14:14:26 +00:00
|
|
|
sudo apt-get install build-essential git patch wget unzip \
|
|
|
|
autoconf cmake libtool nasm luarocks \
|
|
|
|
libssl-dev libffi-dev libsdl2-dev linux-libc-dev:i386
|
2014-03-25 14:26:36 +00:00
|
|
|
```
|
2015-10-06 14:14:26 +00:00
|
|
|
Note that the `linux-libc-dev:i386` package is only necessary for x86_64 machines.
|
2013-03-24 14:08:42 +00:00

A recent version of Android SDK/NDK and `ant` are needed in order to build
|
|
|
|
Koreader for Android devices.
|
2014-06-04 11:19:22 +00:00
|
|
|
```
|
|
|
|
sudo apt-get install ant
|
|
|
|
```

2014-05-29 13:09:22 +00:00
|
|
|
|
2015-10-06 14:14:26 +00:00
|
|
|
In order to build Koreader package for Ubuntu Touch, the `click` package management
|
|
|
|
tool is needed, Ubuntu users can install it with:
|
|
|
|
```
|
|
|
|
sudo apt-get install click
|
|
|
|
```
|
|
|
|
|
2014-10-26 01:07:12 +00:00
|
|
|
You might also need SDL library packages if you want to compile and run
|
2015-10-06 14:14:26 +00:00
|
|
|
Koreader on Linux PC. Fedora users can install `SDL` and `SDL-devel` package.
|
|
|
|
Ubuntu users probably need to install `libsdl2-dev` package:

|
To build installable package for Kindle:
|
2013-04-20 22:28:42 +00:00
|
|
|
```
|
2015-10-03 07:41:07 +00:00
|
|
|
make TARGET=kindle clean update
|
2013-08-28 21:36:19 +00:00
|
|
|
```
|
|
|
|
|
2014-05-29 13:09:22 +00:00
|
|
|
To build installable package for Kobo:
|
2013-08-28 21:36:19 +00:00
|
|
|
```
|
2015-10-03 07:41:07 +00:00
|
|
|
make TARGET=kobo clean update
|
2013-04-20 22:28:42 +00:00
|
|
|
```
|
2013-03-24 14:08:42 +00:00
|
|
|
|
2015-01-17 01:09:36 +00:00
|
|
|
To build installable package for PocketBook you need first to obtain the SDK
|
|
|
|
from PocketBook:
|
|
|
|
```
|
|
|
|
make pocketbook-toolchain
|
|
|
|
```
|
|
|
|
then similarly with Kindle and Kobo building run this command:
|
|
|
|
```
|
2015-10-03 07:41:07 +00:00
|
|
|
make TARGET=pocketbook clean update
|
|
|
|
```
|
|
|
|
|
2015-10-06 14:14:26 +00:00
|
|
|
To build installable package for Ubuntu Touch
|
2015-10-03 07:41:07 +00:00
|
|
|
```
|
|
|
|
make TARGET=ubuntu-touch clean update
|
2015-01-17 01:09:36 +00:00
|
|
|
```
|
|
|
|
|
2014-10-26 01:07:12 +00:00
|
|
|
To run, you must call the script `reader.lua`. Run it without arguments to see
|
|
|
|
usage notes. Note that the script and the `luajit` binary must be in the same
|
|
|
|
directory.

|
-------------------
|
|
|
|
|
2014-06-01 15:16:45 +00:00
|
|
|
Make sure the "android" and "ndk-build" tools are in your PATH variable
|
|
|
|
and the NDK variable points to the root directory of the Android NDK.
|
2014-05-29 13:09:22 +00:00
|
|
|
|
|
|
|
First, run this command to make a standalone android cross compiling toolchain
|
|
|
|
from NDK:
|
|
|
|
```
|
|
|
|
make android-toolchain
|
|
|
|
```
|
|
|
|
|
|
|
|
Then, build installable package for Android:
|
|
|
|
```
|
2014-06-04 09:35:47 +00:00
|
|
|
make TARGET=android clean androidupdate
|
2014-05-29 13:09:22 +00:00

For emulating KOReader on Linux and Windows
|
2014-05-29 13:09:22 +00:00
|
|
|
-------------
|
2013-03-24 19:13:03 +00:00
|
|
|
|
2014-09-25 14:25:43 +00:00
|
|
|
To build an emulator on current Linux machine just run:
|
2013-03-24 19:13:03 +00:00
|
|
|
```
|
2014-06-04 09:35:47 +00:00
|
|
|
make clean && make
|
2013-03-24 16:18:53 +00:00
|
|
|
```
|
2013-03-24 19:13:03 +00:00
|
|
|
|
2014-09-25 14:25:43 +00:00
|
|
|
If you want to compile the emulator for Windows you need to run:
|
|
|
|
```
|
|
|
|
make TARGET=win32 clean && make TARGET=win32
|
|
|
|
```
|
|
|
|
|
2015-10-06 14:14:26 +00:00
|
|
|
To run Koreader on your developing machine
|
2014-06-04 09:35:47 +00:00
|
|
|
(you may need to change $(MACHINE) to the arch of your machine such as 'x86_64'):
|
2013-04-20 22:31:24 +00:00
|
|
|
```
|
2015-10-03 07:41:07 +00:00
|
|
|
cd koreader-emulator-$(MACHINE)/koreader && ./reader.lua -d ../../test
|
2013-04-20 22:31:24 +00:00
|
|
|
```
|
|
|
|
|
2014-10-26 01:07:12 +00:00
|
|
|
To run unit tests in KOReader:
|
2014-03-25 14:26:36 +00:00
|
|
|
```
|
|
|
|
make test
|
|
|
|
```
|
|
|
|
|
2015-04-27 00:43:32 +00:00
|
|
|
To run Lua static-analysis for KOReader:
|
|
|
|
```
|
|
|
|
make statick-check
|
|
|
|
```
|
|
|
|
|
2014-03-25 14:26:36 +00:00
|
|
|
You may need to checkout the [travis config file][travis-conf] to setup up
|
2014-10-26 01:07:12 +00:00
|
|
|
a proper testing environment. Briefly, you need to install `luarocks` and
|
|
|
|
then install `busted` with `luarocks`. The "eng" language data file for
|
2014-03-25 14:26:36 +00:00
|
|
|
tesseract-ocr is also need to test OCR functionality. Finally, make sure
|
|
|
|
that `luajit` in your system is at least of version 2.0.2.
|
|
|
|
|
2013-04-20 22:31:24 +00:00
|
|
|
You can also specify size of emulator's screen via environment variables.
|
|
|
|
For more information, please refer to [koreader-base's README][base-readme].
|
2013-03-24 19:13:03 +00:00
|
|
|
|
2014-01-01 21:07:28 +00:00
|
|
|
To use your own koreader-base repo instead of the default one change KOR_BASE
|
|
|
|
environment variable:
|
|
|
|
```
|
2014-06-04 09:35:47 +00:00
|
|
|
make KOR_BASE=../koreader-base
|
2014-01-01 21:07:28 +00:00
|
|
|
```
|
|
|
|
|
|
|
|
This will be handy if you are developing koreader-base and want to test your
|
|
|
|
modifications with kroeader frontend. NOTE: only support relative path for now.

Some strings contain variables that should remain unaltered in translation.
|
|
|
|
For example:
|
|
|
|
|
|
|
|
```lua
|
|
|
|
The title of the book is %1 and its author is %2.
|
|
|
|
```
|
|
|
|
This might be displayed as:
|
|
|
|
```lua
|
|
|
|
The title of the book is The Republic and its author is Plato.
|
|
|
|
```
|
|
|
|
To aid localization the variables may be freely positioned:
|
|
|
|
```lua
|
|
|
|
De auteur van het boek is %2 en de titel is %1.
|
|
|
|
```
|
|
|
|
That would result in:
|
|
|
|
```lua
|
|
|
|
De auteur van het boek is Plato en de titel is The Republic.
|
|
|
|
```

Ccache can speed up recompilation by caching previous compilations and detecting
|
|
|
|
when the same compilation is being done again. In other words, it will decrease
|
|
|
|
build time when the source have been built. Ccache support has been added to
|
|
|
|
KOReader's build system. Before using it, you need to install a ccache in your
|
|
|
|
system.

2013-04-20 22:28:42 +00:00
|
|
|
* install from source:
|
|
|
|
* get latest ccache source from http://ccache.samba.org/download.html
|
|
|
|
* unarchieve the source package in a directory
|
|
|
|
* cd to that directory and use:`./configure && make && sudo make install`
|
|
|
|
* to disable ccache, use `export USE_NO_CCACHE=1` before make.
