Question

我正在尝试为icecast2 / shoutcast创建一个源代码。但在编译完所有内容后，我遇到了分段错误。在使用gdb进一步调试后，我收到了更详细的错误。我不知道任何形式的c，所以我不确定该怎么做这个错误

Program received signal SIGSEGV, Segmentation fault.
send_mp3 (self=0x988eb0, buff =  0xa5c154 "" at mp3.c:175175 mp3.c: No such file or directory.

我想也许是循环使用了很多资源。但无论我设置多少time.sleep（），我仍然得到相同的结果。

正如考克斯指出的那样，问题确实是libshout的编译问题。但它只适用于debian 7而不是ubuntu 12.我认为原因是因为我没有在ubuntu中安装libogg我只安装了vorbis，我认为这是同样的事情。我还安装了mp3编解码器以防万一。

shout-python分段错误我该怎么解决这个问题？
