Nauty编译失败 gtools.c:237:1: error: conflicting types for ‘getline’

gtools.c:237:1: error: conflicting types for ‘getline’
getline(FILE f) / read a line with error checking */
^
In file included from nauty.h:43:0,

from gtools.h:30,
from gtools.c:7:
/usr/include/stdio.h:678:20: note: previous declaration of ‘getline’ was here

原因

---

主要是gcc编译库stdio.h中含有 getline方法，导致重名，

nauty的gtools中先导入了stdio然后自定义了getline方法，故报错

解决

官方解决办法

answer:

In Ubuntu, we've applied the attached patch to achieve the following:

• Fix FTBFS: gtools.c getline renamed to gtools_getline. (LP: #521190)

We thought you might be interested in doing the same.

即将 getline重命名为gtools_getline，
注意调用重命名方法
