java - 为什么Avahi的“ant测试浏览”会失败并显示“libavahi4j.so: undefined symbol :avahi_malloc”？

我能够按照instructions成功构建avahi，但是快速开始运行“ ant test-browse”的下一步会导致符号查找错误，并且我对如何继续解决此问题感到困惑。我确实发现以下post出现了类似的问题，但没有取得任何进展（看来该线程从未公开公开解决过）。这是我看到的错误输出：

myUser@ubuntu:~/Downloads/avahi4j-0.1$ ant test-browse
Buildfile: /home/myUser/Downloads/avahi4j-0.1/build.xml

最佳答案

终于找到了解决方法：export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libavahi-common.so:/usr/lib/x86_64-linux-gnu/libavahi-client.so

如果有人可以阐明为什么需要进行手动黑客攻击，那么我很乐意就标准构建过程为何对我不起作用的建议（在Ubuntu上）。
