Cannot open library

[creperozelot]

I installed the library jdave to maintain our audio bot in discord with thier newer standards.

I got this error message:

this are the permission of the file:

root@manage:/home/discord/musicbot# ls -l /tmp/jdave11547943059811674748/dave9096768902076792803.so

i guess the error is that the file isn't executable.
However i also cannot edit the tmp directory via default methods

See here:

new File(System.getProperty("user.dir") + "/tmp").mkdir();
System.setProperty("java.io.tmpdir", System.getProperty("user.dir") + "/tmp");

Possible to edit the tmp directory?
Or any other solution to this case?

Edit: Locally on my windows machine everything just works fine.

What linux distribution are you using? You likely have a GLIBC version that is too old for this library. You can use ldd -r /tmp/jdave11547943059811674748/dave9096768902076792803.so to check for linker errors.

[creperozelot]

I am using Debian 12

thats the output I got from the command:

Then I would recommend updating to a newer version or using docker images. This library expects GLIBC 2.38 at the moment as you can see in the output of that command.

[creperozelot]

hmm.. okay thank that helps a lot.
As quick question, possible to specify a library path as System Property?
e.g.

System.setProperty("LD_LIBRARY_PATH", "/path/to/newer/version");

[creperozelot]

As small addition, I guess it would be helpfull for a small information that this library requires glib 2.38 or higher in order to run properly

Ty in advance

@creperozelot I opened a PR that has a workaround for this, if you're willing to build libdave from source (which is surprisingly annoying).

[creperozelot]

Thanks, actually it is not necessarily required to compile this from source, since many distributions already provide a third-party version for download, even if it is not included directly in the system packages.

EDIT: As Addition I (or any contributor) will/can close this issue on merge on #31

As quick question, possible to specify a library path as System Property?

I've released 0.1.8 with a new system property for this. You should be able to load it from a path using -Djdave.library.path=/path/to/libdave.so.
