sendmail, 4th Edition

SM_...

sendmail porting settings (V8.12 and above) Port with confENVDEF

Beginning with V8.12, the per-operating-system compile-time macros were removed from the sendmail/conf.h file, and were moved into the include/sm/conf.h file. In addition to moving them, they were also all prefixed with the characters SM_.

These compile-time macros are most certainly defined correctly for your operating system. In the rare event you are porting sendmail to a new operating system, you might need to tune these on a selective basis:

SM_CONF_BROKEN_SIZE_T

On most systems, the size_t type is defined as an unsigned variable. When porting, if that is not the case on your system, define this compile-time macro:

APPENDDEF(`confENVDEF', `-DSM_CONF_BROKEN_SIZE_T=1')

SM_CONF_BROKEN_STRTOD

The sendmail program uses printf(3) and scanf(3) with double-precision conversions, which will cause them to return improper results on some operating systems. When porting, if your operating system returns improper results, you can define this compile-time macro:

APPENDDEF(`confENVDEF', `-DSM_CONF_BROKEN_STRTOD=1')

See libsm/t-float.c to discover how to detect whether this is needed.

SM_CONF_GETOPT

The sendmail program, and all its companion programs, use the getopt(3) routine to parse command-line arguments. When porting, if your compiler library lacks a getopt(3) routine, define this compile-time macro with a value of zero:

APPENDDEF(`confENVDEF', `-DSM_CONF_GETOPT=0')

SM_CONF_LDAP_MEMFREE

When porting, if your LDAP library includes ...
