de2 uClinux drivers

hello,

i prepared everything as it is described on alterawiki, downloaded nios2-linux-20100621.tar. Make was fine with default kernel settings. Now i try to include drivers for lcd_16207 and other components but it gives many errors. Why the drivers which are included in nios2-linux-20100621.tar dont want to compile? Where can I get any good drivers?

Another question is about ptf file, if I get time-limited files can I use them to make uClinux? Now I use ptf and sof from demo projects.
