My system windows7 64 bit, java 8 64 bit. I think problem, that freetype.dll not seen outside eclipse. I found it inside jar (jpod dependencies). How I can correctly include this dll in packaging jar, and why it works from eclipse?

Solution

  • This question is from May but in case anyone still has this problem ... The Freetype dll is automatically extracted from the jar file into your temp folder and loaded from there. But the message you get means that the JNA bridge cannot be initialized. That's a problem with your classpath. You need jna.jar and the other jpod dependencies in your classpath.
