[Rpi Buster] JNA Native: java.lang.UnsatisfiedLinkError: Native library (libjnidispatch.so) not found

[Polymar]

LHello,
After upgrading to Buster release, I realized that filebot was moving no more my TV shows in the correct folder.

I ran the sysinfo script that showed a problem with JNA Native but even after reinstalling it the problem was not solved.
This is the output

Can someone point me in the right direction please?
Thanks in advance,
Renato

You're missing the JNA native libraries. The JNA native libraries are typically installed by apt automatically when filebot is installed.

Is JNA installed? If yes, where is jnidispatch?

Code: Select all

find /usr/lib '*jnidispatch*'

How did you install FileBot?

What does the console say if you run the the installer commands?

[Polymar]

Hello,
thanks for the reply.

Code: Select all

find /usr/lib '*jnidispatch*'

is not found on my rpi.
I installed it using the deb.sh you mentioned in your reply: trying to run it again gave me THIS I can't see any error.

[rednoah]

libjnidispatch should be at this location according to the package file listing:

Code: Select all

/usr/lib/arm-linux-gnueabihf/jni/libjnidispatch.system.so

https://packages.debian.org/buster/armh ... i/filelist


If it's not there, then FileBot will not find it.


I'd start by getting a file listing for the libjna-jni package that your distribution uses to see where they put the *.so file. You might have to ask in the Raspberry Pi forums on how to contact the package maintainers on issues where the Raspberry Pi package is different from the Debian package.

Hello, before posting anywhere else I took a look to the file system:


The file IS there but even if I run the find as root nothing pops up.
Could it be a permission problem at this point?

[rednoah]

What does filebot -script fn:sysenv say?

Code: Select all

filebot -script fn:sysenv

Does file listing work?

Code: Select all

find /usr/lib/arm-linux-gnueabihf/jni

/usr/lib are system files. They're always owned by root. That's why you need root to use apt to install packages. rw-r--r-- means these files can be read by all users so that should be fine.

[Polymar]

THIS is the output of the script.

This is the command:

Sorry. I'm out of ideas. Looks like everything is configured correctly. And the library is there. So it should work. Makes no sense to me.

Code: Select all

jna.boot.library.name: jnidispatch.system
jna.boot.library.path: /usr/lib/arm-linux-gnueabihf/jni

You could try googling for generic JNA debug advice. There's a few options you could try that might give you some insights on what JNA is trying to do step by step:

Code: Select all

export JAVA_OPTS="-Djna.debug_load=true -Djna.debug_load.jna=true"
filebot -script fn:sysinfo

find not being able to find a file that we know is there is also a hint, and very strange. You could try a few things with find to see what works and what doesn't. Perhaps find and JNA can't find the jnidispatch library for the same reason.




EDIT:

I also found some Debian-specific patches that seem to hardcode/replace the search path with arm-linux-gnueabi and thus actively break things on machines with less popular architectures:
* https://sources.debian.org/patches/libj ... -fs.patch/
* https://sources.debian.org/patches/libj ... ary.patch/



EDIT 2:

That patch also seems to hardcode /usr/lib/jni as search path. Check if a copy of libjnidispatch.system.so is there as well, and if not, copy it there.

[Polymar]

I'll give it a try and get back with the results. Thanks again for the suggestions

Try setting jna.nosys=false and see if that makes things work:

Code: Select all

filebot -script fn:properties --def jna.nosys=false
filebot -script fn:sysinfo

[Polymar]

The problem seems to be solved! what did the new script do?

[rednoah]

Setting -Djna.nosys=false will force JNA to load the library via System.loadLibrary() which in turns respects our -Djava.library.path=/usr/lib/arm-linux-gnueabihf/jni property.

hello,
i have been using filebot for years without problem but after upgrading to buster, my tvshows won't move in the correct folder.

Code: Select all

filebot -script fn:sysinfo

returns:

and setting

Code: Select all

filebot -script fn:properties --def jna.nosys=false

changes nothing...
i have the same sysenv as Polymar

i tried the portable version of filebot and the java error disappeared but my tvshows weren't moving in the correct folder either.
if something else pop on your mind
Thanks a lot

[chapototo]

allright,
after renaming a subfolder from the download path from "films" to "temp" , my tvshows move at the right place. But using Filebot-portable. With the apt install, i'm still having the error

[rednoah]

Well, apt shouldn't allow you to have different versions of the same package installed, yet here's libjnidispatch in triplicate, so dependency hell?

was just an old symlink.

I tried removing via apt and reinstalling but it doesn't change anything. Should i reinstall java too?

[chapototo]

well, nevermind, i'll stick with the portable version. Thanks !
