[En-Nut-Discussion] compiling error : undefined symbol '_cmemcpy'

[Rodrigo Garbi]

Hi!

I am trying to successfully compile any NUT/0S 4.2.1 sample project with
iccAVR v6.3 but I am always getting some kind of compiling error.

I tried to compile INETQ project and I have got the following message from
iccAVR v6.3:

C:\icc63\bin\imakew -f inetq.mak
iccavr -c -IC:\ethernut\build-mmnet01-icc\include -IC:\ethernut\nut\include

!ERROR file 'tcpsock.o': undefined symbol '_cmemcpy'
C:\icc63\bin\imakew.exe: Error code 1
Done: there are error(s). Exit code: 1


Can you help me??

At first, when using NUT/OS Configurator, I was getting some Warning
message:
vfscanf_P.c(82) [warning]: Calling function without prototype may cause
error
......
.....

So I noticed that the problem was with memcpy_P function.
I have also found out that in iccavr7 STRING.h header there is a line: void
*cmemcpy(void *, const void *, size_t);
that wasn`t in  iccavr63 STRING.h header, so I add that line to this header
and NUT/OS configurator
stopped showing those warning messages when building libraries and directories.

Well, I hope someone can help me.

Thanks in advance

Garbi, Rodrigo

PD: For those asking themselves why don´t I compile the project with
iccAVR7, the answer is that this version is DEMO while iccAVR63 in my PC is
full.
