How to configure the location for the shared library so file in Bridj

[Daniel Korzekwa]

Hello,

Using brid-0.7.0.jar. I managed to make bridj working for calling c from Scala only by setting @Library("mylibrary.so") and putting mylibrary.so file in the root scala project directory.

Is it possible to configure bridj to look for a native library under a classpath dir?, e.g. $project_dir/target or to configure the directory for native libs in some way?.

Also if I change Library("mylibrary.so") to Library("mylibrary") then bridj fails with:

INFO: Library not found : mylibrary

*** RUN ABORTED ***

  java.lang.UnsatisfiedLinkError:

Yes, you can call BridJ.addLibraryPath(path.getCanonicalPath) to set the path for the main library.
You can also call BridJ.getNativeLibrary(libName, libFile) to force BridJ to load other libraries that your lib depends on from specific files (otherwise it may extract them to a temprorary directory).

Do both before calling BridJ.register() and you get control over where it loads libraries from.

Also if I change Library("mylibrary.so") to Library("mylibrary") then bridj fails with:

I am not sure, I have just looked at code I have for this, and while I am using windows dlls, I don't actually have the .dll suffix for the main library (I do have it for the ones it depends on, though).

HTH,
