Cannot open library #30
Description
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.soto check for linker errors.creperozelot commentedon Mar 7, 2026
I am using Debian 12
thats the output I got from the command:
MinnDevelopment commentedon Mar 7, 2026
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 commentedon Mar 8, 2026
hmm.. okay thank that helps a lot.
As quick question, possible to specify a library path as System Property?
e.g.
creperozelot commentedon Mar 8, 2026
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 commentedon Mar 16, 2026
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
MinnDevelopment commentedon Mar 29, 2026
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.
