[BRLTTY] Build brltty with support for espeak-ng

[Tage Johansson]

I'm sorry if I send this message twise, but something happened with my 
internet connection first time I sent it, so I'll send it again so I'm 
sure it will be sent.


If I just install espeak-ng in arch linux and run:


$ ./configure && make

I get an error because libespeak.so is not included in espeak-ng on arch 
linux. Probably brltty should not try to build the espeak-driver 
automaticly if espeak-ng is available.

But if I run:

# ln -s /usr/lib/libespeak-ng.so.1 /usr/lib/libespeak.so.1

# ln -s /usr/lib/libespeak-ng.so.1 /usr/lib/libespeak.so

$ ./configure && make

It works!


How ever, then I found another problem. All speech messages are 
enqueued. So if I walk two lines quickly, brltty speaks the first line 
done before it starts to speak the second line. I have set "say line 
mode" to immediate. This is probably a bug and I would be very pleased 
if it could be fixed.


Best regards,

Tage
