jlibtorrent UnsatisfiedLinkError #210

Closed asadsm closed 5 years ago

asadsm commented 5 years ago

I've gone through all the issues posted here regarding this but I haven't been able to solve it. I'm using gradle on Linux using IntelliJ IDEA so I added the following:

compile 'com.frostwire:jlibtorrent:1.2.0.18'

and then downloaded the jlibtorrent-linux jar, unpacked it and added the so. So the path looks something like this:

/home/asmalik/libs/libjlibtorrent-1.2.0.18.so

Now I added /home/asmalik/libs to my java library path but gives the following error:

I even tried running it using the command line like this:

java -Djava.library.path=/home/asmalik/libs -cp torlib-1.0.jar Main but that didn't work. I also tried adding it as a NativeLibrary via Intellij IDEA but the same issue. I tried moving the .so inside the project directory and add that to the library.path but same result.

The output actually shows the library path being set:

I also tried updating my bashrc with the following:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/asmalik/libs

and again....same issue.

Am I missing something really obvious here?

I need to know your Linux distribution and architecture and also confirm that you are using the correct library architecture on it.

aldenml commented 5 years ago

Can you confirm that you using the 64 bit version of libjlibtorrent-1.2.0.18.so?

asadsm commented 5 years ago

Using the one under: /lib/x86_64 when I uncompress the jar. There is no .so file in the x86 folder

proninyaroslav commented 5 years ago

I got the same error from user of my app. There was a first case. P.S: 1.2.0.18-RC11 version

@asadsm can you run > ldd /home/asmalik/libs/libjlibtorrent-1.2.0.18.so and paste the output?

@proninyaroslav In my experience android has a weak update process with the native libraries, we mitigated it with the suffix of the library but we were still having some errors like that.

asadsm commented 5 years ago

Not a C++ developer but looks like that might be the issue?

proninyaroslav commented 5 years ago

@asadsm I think you have an incompatible version of glibc from your distibutive.

aldenml commented 5 years ago

yes, that's the problem, a missing or incompatible version of glibc. At this moment I have no way to help you with that in CentOS, I'm not familiar with that distribution or yum.

asadsm commented 5 years ago

Understood. Thanks for the quick help!
