Hello,
some time ago I mentioned trying to build Exim for SunOS 4 and Phil asked
for patches. Here is a start:
Trying to build exim, I found its /bin/sh to be insufficient.
How about switching to bash if it is found? That works fine for me in
scripts/reversion and scripts/lookups-Makefile:
if [ -x /usr/local/bin/bash ]
then
SHELL=/usr/local/bin/bash
export SHELL
fi
I suppose many owners of old systems have bash installed to get around
their /bin/sh.
src/buildconfig.c could take
#include "os.h"
and OS/os.h-SunOS4 needs
typedef int ssize_t;
typedef struct __res_state *res_state;
typedef int sig_atomic_t;
typedef long long int64_t;
In src/exim.h, I miss an #if around including <inttypes.h>:
#if (__STDC_VERSION__ >= 199901L)
#include <inttypes.h>
#endif
It is convenient to add this in OS/Makefile-SunOS4:
HAVE_IPV6=
Sure, it is not set in OS/Makefile-Default, but it makes building exim for
multiple
platforms easier and SunOS 4 is not likely to change. ;-)
So much for a start.
Michael
