编译时链接我的动态库出现错误undefined reference to ‘XXXXXX’
如题,之前没问题,编译了自己的动态库,又编译自己的测试程序,能链接到这个动态库。rn可是,今天,我又重新编译了自己的动态库, 到了编译测试程序的时候,gcc居然报错,<em>错误</em>信息大致这样:rn<em>undefined</em> <em>reference</em> to ‘XXXXXX’rn也就是说动态库里没有这个程序使用的函数。rn但是,我用mn命令列出动态库的符号清单,清单中,我看到了这些被报错不存在的函数名。rn这是什么情况?

undefined reference to 错误解决方法总结
在编写C++时,会遇到一类<em>错误</em>的错。 总结起来为几类 一、是 Linux环境<em>错误</em>  具体没有深入研究,可以参考http://blog.csdn.net/cserchen/article/details/5503556。 二、使用codeblock这类需要自己配置路径,要把所有文件添加到Build target中。配置方法参考下面两个博客:       http://blog.csdn.
