Use this patch.

I discovered this when compiling in Solaris. I think it's just some versions of gcc that are picky about the || operands

So people are reading my posts but not replying to them tongue

I thought I'd update you all on the progress. I've managed to get dhcp_getmac working by dumping a solaris version of getifaddrs() into the compilation.
Also a version of clearenv() was required to get chilli.c to stop showing compile errors.

I'm now having some compile errors with dhcp_open_eth, dhcp_new and dhcp_receive. I think because some structures aren't implemented in Solaris?

Here's the errors I get:

Configure doesn't appear to include these on solaris system


Download http://vtun.sourceforge.net/tun/tun-1.1.tar.gz

gzip -d tun-1.1.tar.gz

tar -xf tun-1.1.tar

cp tun-1.1/solaris/if_tun.h /usr/include/net

Solaris development doesn't include this file by default.

I'm trying to get Chillispot running on Solaris 10.
I've fixed the headers etc. and having come down to the last couple of functions that deal with low level network drives.
dhcp_getmac() and dhcp_open_eth()

can someone explain what these functions do in as much detail as possible? I haven't had much dealings with network interfaces in C, so all help would be appreciated.
