为什么 Avahi "ant test-browse"因"libavahi4j.so: undefined symbol: avahi_malloc"而失败？

Question

我能够按照指令成功地构建avahi，但是运行"ant test-browse"的快速入门的下一步导致符号查找错误，我很困惑如何继续对这个问题进行故障排除。我确实发现下面的帖子显示了一个类似的问题，但没有取得任何进展(似乎这个线程从来没有公开解决)。下面是我看到的错误输出:

Answer 1

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

如果有人能说明为什么需要手工修改，我很乐意建议为什么标准的构建过程对我不起作用(这是在Ubuntu上)。
