VLCJ on Mac OSX Unsatisfied Link Error (darwin/libvlc.dylib)
libvlc, macos, unsatisfiedlinkerror, vlcj
Solution
Turns out it was just a silly mistake on my part. The path I gave was `"/Applications/VLC/Contents/MacOS/lib"`, and it should have been `"/Applications/VLC.app/Contents/MacOS/lib"`. I forgot that VLC had a .app extension. I'll go bury my head in the sand now.
Problem
I'm trying to initialize VLCJ to do some streaming as part of an application I'm working on. Going by the official tutorial, I'm using the following code to try and load the library: ``` NativeLibrary.addSearchPath( RuntimeUtil.getLibVlcLibraryName(), "/Applications/VLC/Contents/MacOS/lib" ); Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class); ``` When I run it, I get the following error: ``` Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'vlc': JNA native support (darwin/libvlc.dylib) not found in resource path (/Users/iamparker/Documents/workspace/VLCStreamer/target/classes:/usr/jar/vlc/vlcj-3.0.1-javadoc.jar:/usr/jar/vlc/vlcj-3.0.1-sources.jar:/usr/jar/vlc/vlcj-3.0.1-test-sources.jar:/usr/jar/vlc/vlcj-3.0.1-tests.jar:/usr/jar/vlc/vlcj-3.0.1.jar:/usr/jar/vlc/jna-4.1.0.jar:/usr/jar/vlc/jna-platform-4.1.0.jar) at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:220) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:322) at com.sun.jna.Library$Handler.<init>(Library.java:142) at com.sun.jna.Native.loadLibrary(Native.java:387) at com.sun.jna.Native.loadLibrary(Native.java:366) at com.thundercats.vlcstreamer.Main.loadNative(Main.java:33) at com.thundercats.vlcstreamer.Main.main(Main.java:16) ``` It looks like it's not even searching the path that I gave it. There is a perfectly good libvlc.dylib inside that directory. Here is the output from running the VLCJ NativeDiscoveryTest: ``` vlcj: (Info.java:70) | INFO | vlcj: <version not available> vlcj: (Info.java:71) | INFO | java: 1.6.0_65 Apple Inc. vlcj: (Info.java:72) | INFO | java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home vlcj: (Info.java:73) | INFO | os: Mac OS X 10.8.5 x86_64 vlcj: (NativeDiscovery.java:98) | DEBUG | discover() vlcj: (NativeDiscovery.java:101) | DEBUG | jnaLibraryPath=null vlcj: (NativeDiscovery.java:106) | DEBUG | discoveryStrategy=uk.co.caprica.vlcj.discovery.linux.DefaultLinuxNativeDiscoveryStrategy@42b1b4c3 vlcj: (NativeDiscovery.java:109) | DEBUG | supported=false vlcj: (NativeDiscovery.java:106) | DEBUG | discoveryStrategy=uk.co.caprica.vlcj.discovery.windows.DefaultWindowsNativeDiscoveryStrategy@60072ffb vlcj: (NativeDiscovery.java:109) | DEBUG | supported=false vlcj: (NativeDiscovery.java:106) | DEBUG | discoveryStrategy=uk.co.caprica.vlcj.discovery.mac.DefaultMacNativeDiscoveryStrategy@77df38fd vlcj: (NativeDiscovery.java:109) | DEBUG | supported=true vlcj: (AbstractNativeDiscoveryStrategy.java:49) | DEBUG | discover() vlcj: (AbstractNativeDiscoveryStrategy.java:54) | DEBUG | directoryNames=[/Users/iamparker/Documents/workspace/NativeDiscoveryTest, /usr/bin, /bin, /usr/sbin, /sbin, /Applications/VLC.app/Contents/MacOS/lib] vlcj: (AbstractNativeDiscoveryStrategy.java:57) | DEBUG | directoryName=/Users/iamparker/Documents/workspace/NativeDiscoveryTest vlcj: (AbstractNativeDiscoveryStrategy.java:95) | DEBUG | Failed to matched all required files vlcj: (AbstractNativeDiscoveryStrategy.java:57) | DEBUG | directoryName=/usr/bin vlcj: (AbstractNativeDiscoveryStrategy.java:95) | DEBUG | Failed to matched all required files vlcj: (AbstractNativeDiscoveryStrategy.java:57) | DEBUG | directoryName=/bin vlcj: (AbstractNativeDiscoveryStrategy.java:95) | DEBUG | Failed to matched all required files vlcj: (AbstractNativeDiscoveryStrategy.java:57) | DEBUG | directoryName=/usr/sbin vlcj: (AbstractNativeDiscoveryStrategy.java:95) | DEBUG | Failed to matched all required files vlcj: (AbstractNativeDiscoveryStrategy.java:57) | DEBUG | directoryName=/sbin vlcj: (AbstractNativeDiscoveryStrategy.java:95) | DEBUG | Failed to matched all required files vlcj: (AbstractNativeDiscoveryStrategy.java:57) | DEBUG | directoryName=/Applications/VLC.app/Contents/MacOS/lib vlcj: (AbstractNativeDiscoveryStrategy.java:85) | DEBUG | Matched 'libvlc.dylib' in '/Applications/VLC.app/Contents/MacOS/lib' vlcj: (AbstractNativeDiscoveryStrategy.java:85) | DEBUG | Matched 'libvlccore.dylib' in '/Applications/VLC.app/Contents/MacOS/lib' vlcj: (AbstractNativeDiscoveryStrategy.java:88) | DEBUG | Matched all required files vlcj: (AbstractNativeDiscoveryStrategy.java:63) | DEBUG | result=/Applications/VLC.app/Contents/MacOS/lib vlcj: (NativeDiscovery.java:112) | DEBUG | path=/Applications/VLC.app/Contents/MacOS/lib vlcj: (NativeDiscovery.java:114) | INFO | Discovery found libvlc at '/Applications/VLC.app/Contents/MacOS/lib' vlcj: (Test.java:34) | DEBUG | found=true vlcj: (LibVlcFactory.java:164) | INFO | vlc: 2.1.4 Rincewind, changeset 2.1.4-0-g2a072be vlcj: (LibVlcFactory.java:165) | INFO | libvlc: /Applications/VLC.app/Contents/MacOS/lib/libvlc.dylib vlcj: (Test.java:36) | DEBUG | Version: {}2.1.4 Rincewind ```
