Hello together,

I am new here and have a problem compiling the software when I have specified the "--enable-dhcpv4o6 --enable-dhcp6" flags. If I remove the first flag, the system compiles the software without errors.

I get the following error message:

In function ‘forw_dhcpv4_response’,
inlined from ‘dhcpv6’ at dhclient.c:1802:5:
dhclient.c:1907:2: error: writing 16 bytes into a region of size 1 [-Werror=stringop-overflow=]

make[1]: Leaving directory '/root/tools/software/dhcp-4.4.2-P1/client'

What am I possibly doing wrong here? How can I correct this error?
Best regards
