Hello,
I did compile v.digit2 on my Linux machine, but when I try in use my
digitizer, I can a message "Out of Sync with the Digitizer". Your
explanation that Linux reads of serial port happening faster that
serial port was able to supply information seems to be the problem.
Please let me know if I can get a copy of the v.digit version that
you have modified to work on your Linux machine.
Also, I am unable to compile v.digit on my Linux Machine since i
get a error message while running my gmake file. The error message
I get is;
"V_call.o(text+0xfs):undefined reference to '_waddbytes'
make...[/user2/grass/etc/bin/inter/v.digit] Error 1"
Please give me some suggestions and also let me know if I can have
a copy of your modified v.digit program.
Thanks in advance
