Can't find libjffi-1.2.so on Raspbian Raspberry Pi about jffi HOT 7 OPEN

I was able to get it runing on raspberry pi as well as jruby itself (slow...) but I had manually move the lijffi loaded file to not be in /tmp. I don't remember what else I did but it would likely involve either java.library.path or LD_LIBRARY_PATH. I think it was the former.

It was also a year or more ago so the details were fuzzy but the /tmp bit was the main issue.

Hi Enebo,

Can you please elaborate on this line:

but I had manually move the lijffi loaded file to not be in /tmp

I have tried adjusting where Java sets the tmp folder but don't understand what else you could have done?

Thanks

I believe I manually copied what was dumped into /tmp into a sub directory within my home directory and then set -J-Dliibrary.path to that directory. I will have to find my Rasppi to check though...hmm I wonder where it is :)

Hmm, I never see anything in /tmp at all.

Actually, I altered the code in the function loadFromJar() from jffi project so that it just calls: System.loadLibrary("jffi-1.2"); at the beginning of the function with a println() statement preceding it.

Again, that works fine on my Mac but fails on the Pi.

I wonder why that is? very strange.

Any ideas please? Thanks.

Original reporter has been ghosted, and other fixes have come in for ARM support, so I'm going to close this.

I'm reopening this. I had trouble getting JRuby 9.1.6.0 to load on a Raspberry Pi 3 with current Raspbian. No matter where I put the .so it always says "could not load shared library libjffi-1.2.so: file not found" or something similar.

We also have some minor issues running basic commands without native support loaded. I'll file separate issues for those later.

I managed to get jirb up and going but only by commenting out lines in irb/input-method.rb that attempt to open file descriptors directly.

FWIW, if anyone wants to hack on this I can put my raspi online once I'm home next week.
