如何在Ubuntu上构建SVMstruct Python模块

Question

我从here下载了源代码。运行make时，收到以下错误消息：

一切都是“开箱即用”的，所以我怀疑这是Ubuntu的问题。尤其是，我怀疑glibc已经过时了

当我尝试/lib/x86_64-linux-gnu/libc.so.6时，我得到

GNU C Library (Ubuntu EGLIBC 2.19-0ubuntu6.6) stable release version 2.19

最新的版本是2.2.5，但是eglibc没有2.2 branch，这似乎是Ubuntu用户获得glibc的方式。我已经尝试过apt-get upgrade，但我仍然是2.19版本。我该怎么解决这个问题？在

截至2014年，德比安似乎又回到了glibc。在

在MakeFile顶部附近添加LIBS=-lm以链接到数学库为我解决了这个问题。在
