svn 编译支持http协议问题

svn 版本1.9.4
系统centos6.2
编译安装的svn是成功了，在linux上执行 svn checkout http://…. 命令时候报错
svn: E170000: Unrecognized URL scheme for
执行svn –version

The following repository access (RA) modules are available:

   * ra_svn : Module for accessing a repository using the svn network protocol.
     - with Cyrus SASL authentication
     - handles 'svn' scheme
   * ra_local : Module for accessing a repository on local disk.
     - handles 'file' scheme

没有’http’ scheme。

原来，svn1.8版本以后，需要serf软件包支持访问 http 协议的版本库，不然就会报错.serf需要用scons来编译安装，所以先安装下scons

pip install scons

注：如果是自己编译的python版本，scons安装成功后，再python的bin路径下编辑下scons文件，将首行#! /usr/bin/env python 修改为自己编译的python执行路径

svn 1.9.4版本需要serf1.3.4以上版本，我下载的是1.3.8

wget https://archive.apache.org/dist/serf/serf-1.3.8.tar.bz2
tar -xvf serf-1.3.8.tar.bz2
cd serf-1.3.8
scons PREFIX=/usr/local/serf APR=/apps/apr/bin/apr-1-config APU=/apps/apr-util/bin/apu-1-config
scons install
scons -c

重新编译svn 加上 –with-serf=/usr/local/serf

./configure  --with-serf=/usr/local/serf

然后将serf的lib路径添加到系统搜索路径

vim /etc/ld.so.conf.d/serf.conf
加入内容：/usr/local/serf/lib
ldconfig

否则会报错
svn: error while loading shared libraries: libserf-1.so.1: cannot open shared object file: No such file or directory

svn –version 看下信息
