jabberd编译安装

一、准备需要安装的软件包(libidn，udns，gsasl)，分别从以下地址下载：

      wget ftp://ftp.gnu.org/gnu/gsasl/libgsasl-1.6.1.tar.gz
      wget http://www.corpit.ru/mjt/udns/udns-0.2.tar.gz
     wget http://ftp.gnu.org/gnu/libidn/libidn-1.9.tar.gz    

1, 操作系统为RedHat Enterprise Linux 5, 选择了最小化安装。我们的目的是不使用系统里现有的库，全部使用我们自己编译的,这样做的目的是搭建出一个不依赖系统jabberd。
2, 准备了使用的安装包：
    cyrus-sasl-2.1.23.tar.gz
    jabberd-2.2.11.tar.bz2
    libidn-1.19.tar.gz

   openssl-1.0.0a.tar.gz

    expat-2.0.1.tar.gz

    libgcrypt-1.4.6.tar.bz2
    mysql-5.0.91-linux-i686-glibc23.tar.gz
    udns_0.0.9.tar.gz
    zlib-1.2.5.tar.gz
    libgsasl-1.4.4.tar.gz

3, 创建目录:
    mkdir -p /usr/local/easyjabberd/app

4, 先安装MySQL:
   我们下载了mysql的是已经编译好的二进制包，直接解压缩就可以使用
   (1), tar zxvf mysql-5.0.91-linux-i686-glibc23.tar.gz
   (2), cp -R mysql-5.0.91-linux-i686-glibc23 /usr/local/easyjabberd/app/mysql

5, 安装expat,用作XML解析
   (1), tar zxvf expat-2.0.1.tar.gz
   (2), ./configure --prefix=/usr/local/easyjabberd/app/expat
   (3), make
   (4), make install

6, 安装libidn
   (1), tar zxvf libidn-1.19.tar.gz
   (2), ./configure --prefix=/usr/local/easyjabberd/app/libidn
   (3), make
   (4), make install

7, 安装udns
   udns的configure没有提供--prefix,所以我们编译后，手动拷贝所需要的文件到/usr/local/easyjabberd/app/udns目录下
   (1), mkdir -p /usr/local/easyjabberd/app/udns/include
   (2), mkdir -p /usr/local/easyjabberd/app/udns/lib
   (3), ./configure
   (4), make
   (5), cp udns.h /usr/local/easyjabberd/app/udns/include/
   (6), cp libudns.a /usr/local/easyjabberd/app/udns/lib/

8, 安装openssl
   (1), tar zxvf openssl-1.0.0a.tar.gz
   (2), cd openssl-1.0.0a
   (3), ./config --prefix=/usr/local/easyjabberd/app/
   (4), make
   (4), make install

9, 安装Cyrus sasl
   (1), tar zxvf cyrus-sasl-2.1.23.tar.gz
   (2), cd cyrus-sasl-2.1.23
   (3), ./configure --prefix=/usr/local/easyjabberd/app/ --with-openssl=/usr/local/easyjabberd/app/ CPPFLAGS="-I/usr/local/easyjabberd/app/include/ -I/usr/local/easyjabberd
/app/include/openssl" LDFLAGS="-L/usr/local/easyjabberd/app/lib"
   (4), make
   (5), make install

10, 安装zlib
    (1), tar zxvf zlib-1.2.5.tar.gz
    (2), cd zlib-1.2.5
    (3), ./configure --prefix=/usr/local/easyjabberd/app/
    (4), make
    (5), make install

11,  安装Jabberd2
   (1), tar jxvf jabberd-2.2.11.tar.bz2
   (2), cd jabberd-2.2.11
   (3), ./configure --prefix=/usr/local/easyjabberd/jabberd2 --enable-mysql=/usr/local/easyjabberd/mysql/ CFLAGS="-I/usr/local/easyjabberd/app/include -I/usr/local/easyjabberd/app/include/openssl" LDFLAGS="-L/usr/local/easyjabberd/app/lib -Wl,-R/usr/local/easyjabberd/app/lib" --with-extra-include-path=/usr/local/easyjabberd/app/include --with-extra-library-path=/usr/local/easyjabberd/app/lib  --with-sasl=cyrus --enable-mio=epoll
   (4), make
   (5), 调试报错，sx/sasl_cyrus.c 23行注释掉

   (6), make
   (7), make install

好了，如果一切顺利，到这里Jabberd2服务器已经编译、安装完成。

二、编译过程中遇到的问题： 

    1) udns包找不到

            udns的configure没有提供--prefix,所以我们编译后，手动拷贝所需要的文件到/usr/local/easyjabberd/app/udns目录下
   (1), mkdir -p /usr/local/easyjabberd/app/udns/include
   (2), mkdir -p /usr/local/easyjabberd/app/udns/lib
   (3), ./configure
   (4), make

   (5), cp udns.h /usr/local/easyjabberd/app/udns/include/

   (6), cp libudns.a /usr/local/easyjabberd/app/udns/lib/

          按照这个步骤操作之后，编译jabberd时仍然会提示udslib找不到的错误，将udns.h和libudns.a分别拷贝到app/include, app/lib目录下就好了

       2) 编译cyrus-sasl-2.1.23提示如下错误：
          #elif with no expression
      编译器版本为4.0，不识别#elif XXX, 修复方法在#elif后面加上defined ：
          #elif defined HAVE_ALLOCA
          #include <stdlib.h>

        3) 编译cyrus-sasl-2.1.23提示如下错误：

digestmd5.c: In function 'digestmd5_client_mech_step':
digestmd5.c:4000: warning: pointer targets in assignment differ in signedness
make[2]: *** [digestmd5.lo] Error 1
make[2]: Leaving directory `/home/eugene/cyrus-sasl2_2.1.23.dfsg1/plugins'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/eugene/cyrus-sasl2_2.1.23.dfsg1'
make: *** [all] Error 2

         发现已经安装过，将原有的卸载掉：

[push@pushtest cyrus-sasl-2.1.23]$ rpm -qa |grep cyrus-sasl
cyrus-sasl-plain-2.1.23-13.el6.x86_64
cyrus-sasl-lib-2.1.23-13.el6.x86_64
cyrus-sasl-2.1.23-13.el6.x86_64
cyrus-sasl-devel-2.1.23-13.el6.x86_64

# rpm -e --allmatches --nodeps cyrus-sasl-plain
# rpm -e --allmatches --nodeps cyrus-sasl-lib 
# rpm -e --allmatches --nodeps cyrus-sasl-plain 
# rpm -e --allmatches --nodeps cyrus-sasl-devel 

        4)  编译jabberd的时候提示错误：

/bin/sh ../libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I..   -I/home/push/wuliang/program/jabberd2/app/include   -I/home/push/wuliang/program/jabberd2/app/include -I/home/push/wuliang/program/jabberd2/app/include/openssl -funsigned-char -MT sasl_cyrus.lo -MD -MP -MF .deps/sasl_cyrus.Tpo -c -o sasl_cyrus.lo sasl_cyrus.c

[push@pushtest sx]$ 

         将sasl_cyrus.c:23的这个编译宏删掉：
