You may follow official compile instructions from [here](https://manual.seafile.com/build_seafile/linux.html). \[[Patch **no longer avaiable, new version at following sections**]()\]

#### Install Seafile on odroid xu
### Install Seafile on odroid xu
Due to failure of my cross-compile to seafile on android. I used develop board as a replacement experiment platform for ARM-seafile testing. I used a [odroid xu](http://www.hardkernel.com/main/products/prdt_info.php?g_code=G137510300620) as hardware standard. Because all I need is an ARM platform, only an ARM-Ubuntu is enough for me. But develop prototype on a board is much fun than coding, I won't address much this time. But I'll start a blog telling some really cool stuff I made for a strange aim.

### How to compile with ftrace?
If we want to debug under android, ftrace is a great tool for working. But, ftrace is not available in android if we used default configure file. Android kernel configuration is in **arch/arm64/kernel/configs**. We need to add few lines under that.

CONFIG_STRICT_MEMORY_RWX=y
CONFIG_FUNCTION_TRACER=y

### How to extract android images: Dump an image
If we want to hold a rooted status after flashing boot, we need to extract an image from android devices. We can first use following command to find which blocks belongs to. According to some references, [this article](http://getpocket.com/redirect?url=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D2450045) provide three ways to dump an image, I picked one for easy using.
~~~~bash
adb shell
ls -al /dev/block/$SOME\_PLATFORM/$SOME\_DEVICE/by-name # {Partitions} -> {Device Block}
# dump file
su
dd if=/dev/block/mmcblk0p37 of=/sdcard/boot.img

&lt;h3 id=&quot;how-to-extract-android-images-dump-an-image&quot;&gt;How to extract android images: Dump an image&lt;/h3&gt;
&lt;p&gt;If we want to hold a rooted status after flashing boot, we need to extract an image from android devices. We can first use following command to find which blocks belongs to. According to some references, &lt;a href=&quot;http://getpocket.com/redirect?url=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D2450045&quot;&gt;this article&lt;/a&gt; provide three ways to dump an image, I picked one for easy using.&lt;/p&gt;
&lt;div class=&quot;highlighter-rouge&quot;&gt;&lt;pre class=&quot;highlight&quot;&gt;&lt;code&gt;adb shell
ls -al /dev/block/&lt;span class=&quot;nv&quot;&gt;$SOME&lt;/span&gt;&lt;span class=&quot;se&quot;&gt;\_&lt;/span&gt;PLATFORM/&lt;span class=&quot;nv&quot;&gt;$SOME&lt;/span&gt;&lt;span class=&quot;se&quot;&gt;\_&lt;/span&gt;DEVICE/by-name &lt;span class=&quot;c&quot;&gt;# {Partitions} -&amp;gt; {Device Block}&lt;/span&gt;
&lt;span class=&quot;c&quot;&gt;# dump file&lt;/span&gt;
su
dd &lt;span class=&quot;k&quot;&gt;if&lt;/span&gt;&lt;span class=&quot;o&quot;&gt;=&lt;/span&gt;/dev/block/mmcblk0p37 &lt;span class=&quot;nv&quot;&gt;of&lt;/span&gt;&lt;span class=&quot;o&quot;&gt;=&lt;/span&gt;/sdcard/boot.img
&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;
