[vlc-devel] commit: tell jna to load libvlc with RTLD_GLOBAL option (Filippo Carone )

[Alexander Bethke]

Hi,

I have a question regarding that change. When building the bindings now, 
I get following error from maven:

bindings/java/core/src/main/java/org/videolan/jvlc/internal/LibVlc.java:[48,23] 
cannot find symbol
symbol  : variable OPTION_DLOPEN_GLOBAL
location: interface com.sun.jna.Library

I couldn't either find the OPTION_DLOPEN_GLOBAL field in JNA's Library 
class source (at least not in JNA version 3.0.9 that maven resolves when 
running mvn install for jvlc, it seems to be in the JNA trunk though).
So how did you build jvlc with that configuration? Or how should I work 
around it? Revert this change, or take a trunk version of jna?

Thanks and regards, Alex
