Name
confOPTIMIZE
Synopsis
The confOPTIMIZE
macro sets the command-line
switch that will be passed to the C-language compiler to tune its
optimization. This macro assigns a value to the O=
Makefile directive. Normally, it is correctly
set for your site in your devtools/OS file.
One reason to change optimization might be to track down a bug that
is causing your installation of sendmail to
core-dump. Just add this line to your site file, and
re-Build with -c
:
define(`confOPTIMIZE', `-g')
The -g
switch causes the compiler to produce a
binary that can later be debugged with a symbolic debugger.
Most often, sendmail core dumps are caused by
improper builds. Always be sure to keep your system and compiler
#include
files up to date and in synchronization
with their corresponding libraries.
Note that the confOPTIMIZE
macro is not the proper
place to set other compile-time macros. Instead use
confENVDEF
(confENVDEF and conf_prog_ENVDEF).
