我正在为程序使用libevent，我在两台计算机A和B上编译了我的程序，在A上执行成功，但是在B上出现以下错误:
error while loading shared libraries: libevent-1.4.so.2: cannot open shared object file: No such file or directory
供引用:
A和B都使用fedora系统，在A和B上，我都下载了
libevent-1.4.14b-stable.tar.gz，并通过configure/make/make install进行安装。在A上

[root@kitch server_agent]# ls -al /usr/local/lib64 | grep libevent
为什么我的程序在B上出现此错误，有什么解决方案吗？
谢谢!
最佳答案
您的“A”系统具有从/usr/lib/libevent-1.4.so.2到/usr/local/lib/libevent-1.4.so.2的符号链接(symbolic link)，而系统“B”则没有。如果您创建了它，那么一切都将开始起作用。
该命令应如下所示。
sudo ln -s /usr/local/lib/libevent-1.4.so.2 /usr/lib/libevent-1.4.so.2
或者，您可以通过导出
/usr/local/lib作为系统“B”的临时修订，将LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib作为测试添加到库路径中。关于linux - 加载共享库: libevent-1. 4.so.2时出错:无法打开共享库文件:，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/17110844/
