[BRLTTY] Compilation problems on Windows

[Siju Samuel]

Hi,

>>I have a Seika 40 display and I'm trying to get NVDA to use brlttythat
I've compiled from source. I am unable to do so because I suspect the
>>service isn't running and it cannot connect to BrlAPI. Also, I don't know
where to look for the error returned by brltty when NVDA tries to >>connect
to BrlAPI."



I would like to add following information in case if it is helpful in
anyway.

A few months back I was trying to run a  chrome based browser application
to use brltty in Windows machine. Basically I compilied brltty using MingW
from source and ran brltty.exe. And programmatically I could invoke
BrlApis from chrome based application  to read and write to refreshable
braille device (Freedom focus).
Today I downloaded  latest NVDA and installed.   Focus 14 is connected and
made sure it is using the Brltty drivers. (using device manager).

First Trial : Started NVDA which was not writing to the device.
*Second Trial : Strated brltty.exe and Then started NVDA, it is writing to
the device etc.  *I assume here some how NVDA is using brltty's APIs . As I
see the logs in brltty's log.

Now coming to compiling brltty, I used an old version (4.5) and today I was
re-using it.

Just  did config and  make and make install .  Used only bare minimum
things  to avoid all other errors coming from compilation .[all using
brltty 4.5 ]
 ./configure --with-braille-driver=fs,-all  --with-screen-driver=-all
--with-speech-driver=-all


Also write a sample program to invoke brlapi and check it is writing to
device or not.  Basically to make  sure brltty can communicate using th usb
device.




I am pasting some of my old notes here :



1.Check out the latest code in Linux machine.
   ./autogen  ( Perform in Linux)
   then copy code to Windows/Mingw


I have the libusb-win32 file downloaded to
/C/brlttywindows/libsub/libusb-win32-bin-1.2.6.0/.

and used

ln -s
"/C/brlttywindows/libsub/libusb-win32-bin-1.2.6.0/include/lusb0_usb.h"
/mingw/include/usb.h
ln -s "/C/brlttywindows/libsub/libusb-win32-bin-1.2.6.0/lib/gcc/libusb.a"
/mingw/lib/
ln -s
"/C/brlttywindows/libsub/libusb-win32-bin-1.2.6.0/bin/x86/libusb0_x86.dll"
/mingw/bin/libusb0.dll



2. Configure and Make  looks everything successful ( after setting up the
USB related symbolic links)
 ./configure --with-braille-driver=fs,-all  --with-screen-driver=-all
--with-speech-driver=-all





3. Then perform the USB-driver related setup in README  and libsub-win32
read me
Copied libsub-win32 related .sys and .lib file as described in the
document.


4. Connected the device and Updated the device Driver to use from
"brltty.inf" file.
  Note that I copied brltty.inf file from the brltty-4.5.tar
  Now it shows LibUSB-Win32 Device :   LibUsb-win32 : Freeedom Scientific
[focus Braille].   And teh devic eprovider is Brltty.


5. Ran Brltty wih

.\bin\brltty -b fs -xno -p none -A auth=none  -l debug  -n -e
--no-release-device > debug.log 2>&1
