Cant install Java on Wand Board Quad running Ubuntu 12.04

Question

I picked up the Wand Board and was curios to see on how well it can perform as a Minecraft Server. So i downloaded the JDK 8 from the official site for ARM and extracted it to my OPT folder, after doing so i ran "java -version" from the folder and it said java is not found.

inaro@linaro-ubuntu-desktop:~$ opt/jdk1.8.0/bin/java -Xmx768M -Xms768M ${GC_OPTS} -jar Tekkit.jar nogui
-bash: opt/jdk1.8.0/bin/java: No such file or directory
linaro@linaro-ubuntu-desktop:~$

Even though it exists!'

linaro@linaro-ubuntu-desktop:~$ cd /opt
linaro@linaro-ubuntu-desktop:/opt$ ls
jdk1.8.0
linaro@linaro-ubuntu-desktop:/opt$ cd jdk1.8.0
linaro@linaro-ubuntu-desktop:/opt/jdk1.8.0$ ls

Any help would be appreciated!

Answer 1

The Oracle JDK 8 release for ARM is built for hard floating point ABI. Is Ubuntu for Wandboard a soft-float or hard-float build? If it is soft float you will get the error you reported above. Try a JDK that is built for the soft float ABI (probably JDK 7 as I don't think Oracle has released a soft-float JDK 8 to date).

Answer 2

Forts, try with:

/opt/jdk1.8.0/bin/java

As I can see, you forgot to put a slash in the front of the command and thi is for sure a problem.

Second, check in Nautilus what exactly is the name of the file. It must to be exactly 'java' and after I saw your comments I suspect that the name of the file contain one or more spaces at the end or maybe other strange character. So try to rename in Nautilus and you will see.

Also I suggest you to add /opt/jdk1.8.0/bin/ directory to your PATH:

export PATH=$PATH:/opt/jdk1.8.0/bin/

Answer 3

Fixed!

The problem was that Java was referencing /lib/ld-linux-armhf.so.3 which does not exist on the system. When you look at /lib the only loader file is /lib/ld-linux.so.3 so just soft link them and it works. Below is how I worked it out and what I did to fix it.
