Hi everyone.
I got the source and got Braille Blaster to build. It does not run however.
Seems it does not have links to a couple of libraries.
Here's the output. Can anyone tell what is wrong here?
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
Display cannot be resolved to a type
The method getDisplay() from the type BBIni refers to the missing type
Display
liblouisutdml cannot be resolved to a type
liblouisutdml cannot be resolved
at org.brailleblaster.Main.main(Main.java:56)
If I copy the executable from the Windows binary distribution it works when in
the same directory so the problem seems to be something with the way I have the
project or environment variables set up.
I'm surprised I don't get compiler errors.
Keith

Hi Jamie,
This will be helpoful, in spite of all the caveats. I'll keep them in mind.
Thanks,
