Gephi 0.8.2 initilizes but fails to launch in linux...

I use Ubuntu 14.04 OS

Attching the dmesg|tail output here:

Seems not relevant but tried installing: libnss-myhostname ->but does not help!

Ditto!
The logo comes up with the message "Loading cached objects..." for about 7 seconds and then gephi dies, returns control at the console.
Tried https://gist.github.com/dcht00/432caaf3e6c50a2202b8, but to no avail. Then, unistalled this bit.
After that probed a bit more in gephi/0.8.2/dev/var/log to find:

System info etc:

Any help would be appreciated. The sooner the better!
Please let me know if I've:
1. Missed installing some dependency; fyi followed the instructions at http://gephi.github.io/users/install/ for linux, to the letter.
2. Having memory issues. Shouldn't be is my guess!

Thanks for your time!
Cheers,
A.

I get the exact same behavior on two computers, one with 14.04 and another with 14.10.

I figured this out. Two things:

1) The documentation on setting JDK_HOME is full of lies
2) Gephi doesn't work for me with jdk 8 on Linux

From here: gephi.github.io/users/install/ [apologies I had to de-linkify that URL because the spam blocker on this forum takes umbrage with github.io]

If you still have the wrong Java package running after following the linux installation procedure described above, then manually set the Java virtual machine. To do so, you have to set the home folder of the desired JVM in the environment variable JAVA_HOME or in the environment variable JDK_HOME.

Actually, the script bin/gephi looks for "jdkhome" [all lowercase, no underscore] rather than "JDK_HOME"

So, I extracted an oracle jdk1.7 into a directory someplace and it successfully launches thus:

Code: Select all

jdkhome=/usr/lib/jvm/jdk1.7.0_67/ ./bin/gephi

You can also edit bin/gephi to permanantise this

Cheers,
