[En-Nut-Discussion] Can't compile NutOs (2)

[Johan van der Stoel]

Dear Harald,

This indeed solved the problem, but after going further I run against
another problem.
Now it is page 24 where it goes wrong: see the logging below.

D:\ethernut\nutapp-13g\httpd>make clean
rm -f httpserv.o urom.o
rm -f httpserv.hex
rm -f httpserv.eep
rm -f httpserv.obj
rm -f httpserv.map
rm -f httpserv.lst urom.lst
rm -f httpserv.bak urom.bak
rm -f urom.c

make: *** [urom.c] Error 2

D:\ethernut\nutapp-13g\httpd>

I think this problem is related to the programmer I use. In the configurator
I only can select (?) avr-uisp-stk500, but I only have your cable which
connects at one side to the centronics port and at the other side to the ISP
port. I also have a E-lab JTAG programmer; both programmers only need a
simple hex file...

How to proceed?

Best regards,
Johan van der Stoel

..or, what did I do that it works here?

Actually the compiler is right in your case.

   for (rc = 0; rc < size;) {
with
   int size
and
   size_t rc;

should result in the warning you got and I did not.

To "fix" this change

CPFLAGS = $(MCFLAGS) -Os -Wall -Werror -Wstrict-prototypes
-Wa,-ahlms=$(<F:.c=.lst) $(DEFS)

in nut/Makedefs.avr-gcc to

CPFLAGS = $(MCFLAGS) -Os -Wall -Wstrict-prototypes -Wa,-ahlms=$(<F:.c=.lst)
$(DEFS)

Then build the system again, ignoring the warnings.
