I can see the WEB pages. But I got some errors. Could I have any suggestion?

Hello, I assume that you did not use the SD card image with all the settings already configured. If you compile on Buster version of Raspbian, you need to uncomment in raspberry.makefile the following line:

CFLAGS+=-DGETOPT_ISSUE

just remove the #, and then recompile.

Thanks a lot for response. Is this link is right for the configured one : http://cpham.perso.univ-pau.fr/LORA/WAZIUP/raspberrypi-buster-WAZIUP-demo.iso.zip ?
