libuv库源代码，编译到make check 报错

@starwing

从github编译libuv库，执行到make check 出错，但是，执行make install却没有问题。

1、下载libuv库源码

https://github.com/libuv/libuv

2、根据以下步骤执行编译

$ sh autogen.sh
$ ./configure
$ make
$ make check
$ make install

在执行到make check时，报以下错误，以上命令全部以sudo执行，但执行make install 却没有问题。

但是通过gcc命令，编译libuv库中的test目录下的echo-server.c文件时，报错如下
