为什么的avahi＆QUOT;蚁测试浏览＆rdquo;失败和QUOT; libavahi4j.so：未定义的符号：avahi_malloc＆QUOT;？ [英] Why does Avahi "ant test-browse" fail with "libavahi4j.so: undefined symbol: avahi_malloc"?

问题描述

我是能够成功地打造每说明的avahi，但下一步运行在符号查找错误蚂蚁测试浏览的结果的快速启动，并且我很困惑如何与解决此问题继续进行。我发现下面的帖子的显示了类似的问题，但WASN ŧ能取得任何进展（似乎线程从未公开反正解决）。以下是错误输出，我看到：

解决方案

终于找到了解决方法：出口LD_$p$pLOAD=/usr/lib/x86_64-linux-gnu/libavahi-common.so:/usr/lib/x86_64-linux-gnu/libavahi-client.so

如果任何人都可以揭示为什么需要本手册的黑客，我会爱，为什么标准构建过程对我来说没有工作的建议（这是在Ubuntu）。

I was able to successfully build avahi per the instructions, but the next step in the quick start of running "ant test-browse" results in a symbol lookup error, and I'm confused about how to proceed with troubleshooting this problem. I did find the following post that showed a similar problem, but wasn't able to make any progress (it seems the thread was never publicly resolved anyway). Here is the error output that I see:

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

init:

解决方案

Finally found a workaround: export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libavahi-common.so:/usr/lib/x86_64-linux-gnu/libavahi-client.so

If anyone can shed light on why this manual hacking is required, I would love suggestions on why the standard build process did not work for me (this is on Ubuntu).
