Hi, Richard
thank you for your response.

YOU are definitely right, My dvscan.c is just empty!. I delete the file
dvscan.c and the compilation pass!
i think the problem come from my processes of compilation. When i did it at
first time, i had not the flex/yacc installed
on my ubuntu 7.04(andlinux <http://www.andlinux.org/>), i completed
my packages flex,bison,byacc when the compile errors came out, once all
installed
i redo ./autogen.sh ./configure make make install, but it does not change
the dvscan.c(don't know why, i will check ).

i owe you a beer, richard. you are welcome in aix en provence, France :)
Keep coding, with obama, datadraw and 42, you can change the world..

Best Regards
Liang Wang
