我在我的源代码中使用 libevent，编译程序后，我运行它，我得到以下错误：

./my_program: error while loading shared libraries: libevent-1.4.so.2: cannot open shared

以前我对如何安装 libevent 和安装类似libverto-libevent-0.2.5-1.fc16.x86_64.rpm. 无论如何，最后我编译并安装了libevent源代码./configure, make and make install，但它安装在/usr/libwhile/usr/lib64被之前的残留.so文件占用，如下：

    [esolve@kity lib]$ ls /usr/lib64|grep "libevent"
    libevent-2.0.so.5
    libevent-2.0.so.5.0.1
    libevent_core-2.0.so.5
    libevent_core-2.0.so.5.0.1
    libevent_extra-2.0.so.5
    libevent_extra-2.0.so.5.0.1
    libevent_openssl-2.0.so.5
    libevent_openssl-2.0.so.5.0.1
    libevent_pthreads-2.0.so.5
    libevent_pthreads-2.0.so.5.0.1
    libeventviews.so.4
    libeventviews.so.4.8.0

    [esolve@kity lib]$ ls /usr/lib|grep "libevent"
    libevent-1.4.so.2
    libevent-1.4.so.2.2.0
    libevent.a
    libevent_core-1.4.so.2
    libevent_core-1.4.so.2.2.0
    libevent_core.a
    libevent_core.la
    libevent_core.so
    libevent_extra-1.4.so.2
    libevent_extra-1.4.so.2.2.0
    libevent_extra.a
    libevent_extra.la
    libevent_extra.so
    libevent.la
    libevent.so
    [esolve@kity lib]$

我该怎么做才能成功运行 ./my_program ？我的系统是fedora 16，我要链接libevent-1.4.so 谢谢！

顺便提一句：

我试过rpm -e all previous-wrongly-installed rpm package，有一些“该包未安装”的提示，我得到了

对于从源代码安装的库，您必须运行 ldconfig，packagemanagers 会为您执行此操作。但是，如果您从源代码构建库，则必须运行

./configure
make
make install

但是也

ldconfig

两者都make install应该ldconfig作为超级用户完成

man ldconfig

我可以告诉你更多关于缓存和更新库的信息。

你不能删除 libevent 2.0 吗？

您可以在 rpm 方法中使用 rpm -e。

或者，在您的 Makefile 中，您可以链接 libevent-2.0 而不是 libevent-1.4。
