GEVENT安装在x86_64失败：“未定义的符号：evhttp_accept_socket”

Question

我试图安装 GEVENT 在新鲜EC2的CentOS 5.3的 64位系统。

由于荫可用的libevent版本是太旧另一包（beanstalkd）我使用下面的命令手动编译/安装libevent-1.4.13-stable：

./configure --prefix=/usr && make && make install

这是从安装GEVENT中输出：

[gevent-0.12.2]# python setup.py build --libevent /usr/lib
Using libevent 1.4.13-stable: libevent.so
running build
running build_py
running build_ext
Linking /usr/src/gevent-0.12.2/build/lib.linux-x86_64-2.6/gevent/core.so to 
    /usr/src/gevent-0.12.2/gevent/core.so
[gevent-0.12.2]# cd /path/to/my/project
[project]# python myscript.py
Traceback (most recent call last):
  File "myscript.py", line 9, in <module>
    from gevent.wsgi import WSGIServer as GeventServer
  File "/usr/lib/python2.6/site-packages/gevent/__init__.py", line 32, in <module>
    from gevent.core import reinit
ImportError: /usr/lib/python2.6/site-packages/gevent/core.so: undefined symbol: evhttp_accept_socket

我严格遵守，在本地VirtualBox的实例（32位）相同的步骤，我没有看到任何错误。

我将如何解决这个问题？

最简单的解决是克隆 git仓库，切换到wip-all分支，并运行python setup.py build_libevent build install其抓斗＆静态建立的libevent针对GEVENT：

# git clone http://github.com/schmir/gevent.git
# cd gevent
# git branch -a
* upstream
  origin/HEAD
  origin/close-socket-cancel-event
  origin/pywsgi-without-basehttpserver
  origin/upstream
  origin/wip-all
  origin/wip-setup-config
# git checkout origin/wip-all
# python setup.py build_libevent build install
