Error compiling network.cpp on Solaris 8

[Craig E. Johnston]

I have run into a problem compiling commoncpp2-1.08 on a Sun running
Solaris 8.0 (SunOS 5.8).

Specifically, in the enumNetworkDevices() method of network.cpp, the
ioctl call to retrieve the MTU is no longer supported using the 'ifreq'
structure from "include/net/if.h".  Sun has moved to an IPv6
implementation that uses a structure named 'lifreq'.  Some ioctl() calls
are still supported for backward compatibility, but not the
ifreq.ifr_mtu union member for the SIOCGIFMTU call.

The following diff is my workaround. (watch the line wrap)

*** network.cpp 2003-03-04 11:51:17.000000000 -0800
--- /project/commoncpp2-1.0.8/src/network.cpp   2003-01-23

                        (InetAddress&)maskaddr =
((sockaddr_in&)devifreq.ifr_addr).sin_addr;

- #ifdef CEJ_SOLARIS_FIX
                if(ioctl(fd, SIOCGIFMTU, &devifreq) == -1)
                        mtu = 0;
                else
                        mtu = devifreq.ifr_mtu;

-               else
-                       mtu = devlifreq.lifr_mtu;
- #endif

               
devs.push_back(NetworkDeviceInfo(ifc.ifc_req[i].ifr_name, addr, brdaddr,
maskaddr, mtu));
        }
