postfix的编译参数

postfix编译参数和选项选项：1.AUXLIBS
           2.CC
           3.CCARGS 
           4.DEBUG
           5.OPT
参数：-I ，-D， -L， -R， -r， -l。各个参数的说明如下：

         -I 指明某一包的库文件所在的地方
        -D The -D option provides a way to define macros at the time you compile Postfix. Add-on packages

for Postfix require that you define a particular macro to tell Postfix to include it when building. For example, if

you want to include support for MySQL, you define the HAS_MYSQL macro:CCARGS='-DHAS_MYSQL'
        -L 加入对某一包的额外库的支持。如：AUXLIBS='-L/usr/local/lib'
        -l 和-L一块儿使用，具体到某一库。如：AUXLIBS='-L/usr/local/lib -lmysqlclient'
        -R -r
The linker uses an argument to include directories in a runtime search path for dynamic libraries. The argument differs depending on your linker and platform. The GNU linker (Linux, FreeBSD) uses -rpath, as does IRIX. Solaris, on the other hand uses -R, and HP-UX uses +b. Consult the manpage for your linker, ld(1), to see which argument you should use to set the runtime library search path.
如：Using the SSL library as an example, if your libssl.so file is located in /usr/local/lib and you are building Postfix on FreeBSD or another system that uses rpath, define AUXLIBS as follows:

AUXLIBS='-L/usr/local/lib -rpath/usr/local/lib -lssl'


下面给出一个例子：可以将它保存成shell，如：install.sh文件

#
# Simple script to create a Makefile to build Postfix.
#

#
# Remember to start by cleaning up or uncomment this line
# to have this script do it every time.
#
#make tidy

#
# Specify all of our options and supporting libraries
#
make makefiles \
CCARGS='-DUSE_SASL_AUTH -DHAS_SSL -DHAS_MYSQL -DHAS_LDAP \
-I/usr/local/include/sasl -I/usr/local/ssl/include \
-I/usr/local/include/mysql -I/usr/local/include' \
AUXLIBS='-L/usr/local/lib -L/usr/local/ssl/lib \
-L/usr/local/lib/mysql -L/usr/local/lib \
-lsasl2 -lcrypto -lssl -lmysqlclient -lz -lm -lldap -llber \
-rpath /usr/local/lib/mysql -rpath /usr/local/lib \
-rpath /usr/local/ssl/lib'

To build Postfix, type:

$ sh build.sh
$ make

一個完整的編譯參數，使用時請注意路徑是否與你系統中的軟體一至。

make -f Makefile.init makefiles 'CCARGS=-DHAS_MYSQL -I/usr/include/mysql -DUSE_SASL_AUTH \
-DUSE_CYRUS_SASL -I/usr/local/include/sasl -DUSE_TLS' \
'AUXLIBS=-L/usr/lib/mysql -lmysqlclient -lz -lm -L/usr/local/lib/sasl2 -lsasl2 -lssl -lcrypto' \，如果你使用的是cyrus认证，不要忘了-DUSE_SASL_AUTH后面的-DUSE_CYRUS_SASL，否则postfix会不支持的 sasl认证的，且maillog里会出现如下此方面的错误日志：

wintim postfix/smtpd[5950]: warning: unsupported SASL server implementation: cyrus
wintim postfix/smtpd[5950]: fatal: SASL per-process initialization failed
