39 By far, the easiest way to compile sendmail is to use the "Build"
44 This uses the "uname" command to figure out what architecture you are
50 If you need to look at other include or library directories, use the
51 -I or -L flags on the command line, e.g.,
53 sh ./Build -I/usr/sww/include -L/usr/sww/lib

212 If you are a system to which sendmail has already been ported you
213 should not have to touch the following symbols. But if you are porting,
214 you may have to tweak the following compilation flags in conf.h in order
215 to get it to compile and link properly:
218 SYS5SIGNALS Use System V signal semantics -- the signal handler
224 HASNICE Define this to zero if you lack the nice(2) system call.
225 HASRRESVPORT Define this to zero if you lack the rresvport(3) system call.
226 HASFCHMOD Define this to one if you have the fchmod(2) system call.
228 HASFCHOWN Define this to one if you have the fchown(2) system call.
231 HASFLOCK Set this if you prefer to use the flock(2) system call

269 will allow root to set only the effective user id to an

291 You can define it to 0 to force it off. It is assumed
292 if you are running a BSD-like system.
299 HAS_GETHOSTBYNAME2 Define this to 1 if your system supports
301 HAS_ST_GEN Define this to 1 if your system has the st_gen field in
313 to scan the arguments twice. This flag will ask sendmail
314 to compile in a local version of getopt() that works
316 another library that introduces a non-standard getopt(3).
320 fsync(2). This will try to simulate the operation using
323 HASGETUSERSHELL Define this to 1 if you have getusershell(3) in your

326 NIS-style support, defaults to /bin/sh and /bin/csh if
327 that file does not exist) to get a list of unrestricted
328 user shells. This is used to determine whether users
329 are allowed to forward their mail to a program or a file.
331 putenv(3) call. Define to 1 to implement it in terms
332 of setenv(3) or to 2 to do it in terms of primitives.

348 ARBPTR_T The type of an arbitrary pointer -- defaults to "void *".
349 If you are an very old compiler you may need to define
350 this to be "char *".
351 SOCKADDR_LEN_T The type used for the third parameter to accept(2),
353 length of a struct sockaddr. Defaults to int.
354 SOCKOPT_LEN_T The type used for the fifth parameter to getsockopt(2)
356 buffer. Defaults to int.
359 LA_ZERO (1) -- it always returns the load average as
361 LA_INT (2) to read /dev/kmem for the symbol avenrun and
365 LA_SHORT (6) to interpret as a short integer.
368 LA_MACH (5) to use MACH-style load averages (calls
370 LA_PROCSTR (7) to read /proc/loadavg and interpret it
371 as a string representing a floating-point
372 number (Linux-style).
375 call to read /dev/kmem.
378 LA_HPUX (10) is an HP-UX specific version that uses the
381 to 32 or 64 bit kernels; it is otherwise very similar
382 to LA_INT.
383 LA_KSTAT (12) uses the (Solaris-specific) kstat(3k)
388 LA_LONGLONG (17) to read /dev/kmem for the symbol avenrun and
392 other parameters that they try to divine: the name of your
393 kernel, the name of the variable in the kernel to examine,
395 and so forth. LA_DEVSHORT uses _PATH_AVENRUN to find the

400 of bits of load average after the binary point -- i.e.,
401 the number of bits to shift right in order to scale the
402 integer to get the true integer load average. Defaults to 8.
403 _PATH_UNIX The path to your kernel. Needed only for LA_INT, LA_SHORT,
404 and LA_FLOAT. Defaults to "/unix" on System V, "/vmunix"
407 variable that holds the load average. Defaults to "avenrun"

430 SPT_PSTAT (3) -- Use the PSTAT_SETCMD option to pstat(2)
431 to set the process title; this is used by HP-UX.
432 SPT_PSSTRINGS (4) -- Use the magic PS_STRINGS pointer (4.4BSD).
433 SPT_SYSMIPS (5) -- Use sysmips() supported by NEWS-OS 6.

437 SPT_PADCHAR Character used to pad the process title; if undefined,
443 variable -- otherwise don't worry about it.
447 SCANF You can set this to extend the F command to accept a
448 scanf string -- this gives you a primitive parser for
449 class definitions -- BUT it can make you vulnerable to
451 SYSLOG_BUFSIZE You can define this to be the size of the buffer that
453 1024-byte buffer. If the buffer is very small (under
454 256 bytes) the log message format changes -- each
455 e-mail message will log many more messages, since it

462 you set this, sendmail considers 0 to be the same as

466 0x7fffffff to strip off the top bit.

875 Solaris and other pre-4.4BSD kernels do not respect ownership or
876 protections on UNIX-domain sockets. The short term fix for this is to
877 override the default path and put such control sockets into root-

879 The long term fix is for all kernels to upgrade to 4.4BSD semantics.
882 The MPE-specific code within sendmail emulates a set-user-id root
884 MPE, nor is there any support for set-user-id programs. Even when
886 access rights of the underlying non-zero uid, but because sendmail is
