1、libevent 在linux下编译链接问题 (2011-04-2511:43:20)转载▼标签： 杂谈分类： 知识收集按照网上例子搞了个httpd的小demo（linvo_httpd.c），遇到一连串问题，努力google了半天，终于得解，记录之~环境：Linux2.6.18-164.el5libevent-1.4.13首先用gcc编译时候报了类似下面信息的一堆错/tmp/ccsKVcym.o:Infunction`main':linvo_httpd.c:(.text+0xdf):undefinedreferenceto`event_init'linvo_httpd.c:(.text+0x

2、f3):undefinedreferenceto`evhttp_start'应该是找不到编译后的libevent库文件所导致，可能是路径问题这次在编译时加上了-levent参数后（让其到系统库中找event库），顺利编译通过gcc-Walllinvo_httpd.c-olinvo_httpd-levent./linvo_httpd 运行之~我擦，又来。。。。./linvo_httpd:errorwhileloadingsharedlibraries:libevent-1.4.so.2:cannotopensharedobjectfile:Nosuchfileordirectory依然是路径问

3、题找不到文件whereislibevent 看下我的libevent默认装到哪里了libevent:/usr/local/lib/libevent.la/usr/local/lib/libevent.so /usr/local/lib/libevent.a哦~在/usr/local/lib/目录下LD_DEBUG=libs ./linvo_httpd -v 看下demo程序究竟是到哪里去找的该文件     32372:     findlibrary=libevent-1.4.so.2[0];searching     32372:      searchcache=/etc/ld.so.c
