Re: [PATCH] Integrating BRLTTY with Gnopernicus (second version)

[Adi Dascal <ad baum ro>]

Hi Mario,

Integrating brltty in gnopernicus seems a really good idea and I am very 
exited about this (Sorry that I did not answer your email earlier, but I was 
out from the office).
I am aware of what else is needed besides your patch, but the first thing to 
do is for me to get the brltty package, which I already have done.
I've downloaded brltty_3.2.tar.gz from
http://packages.debian.org/unstable/admin/brltty.html

OK, first step done. But when I tried to compile the sources 
($ ./configure --prefix=/opt/gnome-2.2 --enable-api
$ make)

I get the following error messages:

make[2]: Entering directory 
`/home/adi/2DO/year2003/month05/2003.05.29/brltty-3.2/Drivers/ViaVoice'

Note : the same error appears with 3.2 -version-sources taken from 
http://dave.mielke.cc/brltty/download.html

Do you have any ideea why is this happening? How can I go further?

Thanks && Best regards,
