I found that there was a post regarding getline in the MingW list but nobody has answered the question. Anyway, I downloaded getline.c and getline.h from Internet and now I can build fsusb-0.1.11 without any errors. I just modified rjlhex.c to include "getline.h" and added getline.o to the OBJS list of the Makefile. As for the libusb problem I think I may have found the problem after reading the Microchip Forum USB section and the lecture notes of the following website. I will try the fix later and report the progress. http://pe.ece.olin.edu/ece/ Regards, Xiaofan -----Original Message----- From: Chen Xiao Fan Sent: Monday, July 25, 2005 2:50 PM ...
