Hi,
With a bit of help from the author, Philip Hazel, I have successfully
built Exim 1.82 under dgux R4.11MU04 generic AViiON mc88100. See
http://www.exim.org for a better description than I could manage and
see
http://maps.vix.com/tsi/ for part of the reason why I wanted to do
this.
Topically for dg-users, the main stumbling block was some DG platform-
dependant code. Part of the Exim code tests for IP source-routed
packets. This uses definitions usually found in netinet/ip_var.h,
notably ipoptions. DG defines this as ip_opts in netinet/in.h *but*
for Intel only. I couldn't see any way of easily getting at the IP
options for m88k and if anybody knows any better please say so.
By applying the following diffs to exim.h and smtp_in.c respectively,
and using the attached Makefile-dg and os.h-dgux, Exim builds without
a whimper.
exim.h
145c145
< #ifndef LINUX_IP_OPTIONS
---
> #if ! defined(LINUX_IP_OPTIONS) && ! defined(NO_IP_VAR_H)
smtp_in.c
709c709
< #if !HAVE_IPV6
---
> #if ! defined(HAVE_IPV6) || ! defined(NO_IP_OPTIONS)
We'd be interested to know if Intel DGUX can use the IP options.
Philip hopes to roll these modest mods into the next release and if
anybody can offer him a long-term DGUX account for testing purposes
then you can help this support continue in the future. (If I could
have, I would have :)
Regards,
Ken
