Fwd: Error when compiling rpcapd in winpcap

[Han Jiang]

Hi I was trying to cross compile rpcapd and use on my asus rt-n16
router ( tomato shibby v132 firmware). I followed the tutorial on
their official website.

https://www.winpcap.org/docs/docs_40_2/html/group__remote.html#UNIX

I successfully build my toolchain with crosstools-ng 1.22, ( it works
I compiled some programs to run on my router, ) , but When I compile
rpcapd , it errors out at this macro definition.

it's in  winpcap/wpcap/libpcap/pcap-int.h


#ifndef HAVE_STRLCPY
#define strlcpy(x, y, z) \
    (strncpy((x), (y), (z)), \
     ((z) <= 0 ? 0 : ((x)[(z) - 1] = '\0')), \
     strlen((y)))
#endif

the same code compiles fine under linux ( centos 7.0)

the error message is


[oglop@t450s rpcapd]$ make

my configure for libpcap is

CC=mipsel-unknown-linux-uclibc-gcc CXX=mipsel-unknown-linux-uclibc-g++
AR=mipsel-unknown-linux-uclibc-ar
RANLIB=mipsel-unknown-linux-uclibc-ranlib ac_cv_linux_vers=2
./configure --prefix=$TARGET_DIR --host=mipsel-uclibc-linux
--with-pcap=linux

and it compiles fine.

How can I get rid of the macro error ? Thanks!
