在这一步时
2.5 安装 kbsbbs
    同样切换到 $(SRCDIR) 目录，进入 kbsbbs 的源代码目录。编辑 site/devel.h
文件，加入下面这一行：
#define BUILD_PHP_EXTENSION 1   /*将php lib编成php extension */

    然后执行下面的一系列命令：
          ./configure --prefix=/usr/local/bbs --enable-site=devel \
              --with-www=/usr/local/www --with-php=/usr/local/include/php \
              --without-mysql --enable-ssh
          make

出现如下错误
In file included from ../src/bbs.h:168,
                 from site.c:1:
../src/site.h:51:1: warning: "BUILD_PHP_EXTENSION" redefined
../src/site.h:19:1: warning: this is the location of the previous definition
site.c: In function `auto_register':
site.c:91: error: too few arguments to function `post_file'
make[2]: *** [site.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

请问如何解决呀？多谢多谢
