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

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

Hi Zh?xu?
I think some background information might help here. Can you reply with
the answers to these questions?
* confirm the DHCP version is 4.4.1-P1?
* What operating system, and version? eg centos, ubuntu, bsd, etc
* gcc version
* the complete command line used with ./configure
This may help someone identify what's going on.
regards,
Glenn
