Redis 2.6.9 安装报错，提示：

zmalloc.h:50:31: error: jemalloc/jemalloc.h: No such file or directory

zmalloc.h:55:2: error: #error "Newer version of jemalloc required"

make[1]: *** [adlist.o] Error 1

make[1]: Leaving directory `/data0/src/redis-2.6.2/src'

make: *** [all] Error 2

解决办法是：

make MALLOC=libc

错误描述

​​安装​​​​Redis​​​ 2.8.18时​​报错​​：


zmalloc.h:50:31: ​​error​​: jemalloc/jemalloc.h: No such file or directory

zmalloc.h:55:2: ​​error​​: #error "Newer version of jemalloc required"

make[1]: *** [adlist.o] Error 1

make[1]: Leaving directory `/data0/src/redis-2.6.2/src'

make: *** [all] Error 2

原因分析

在README 有这个一段话。


Allocator

---------


Selecting a non-default memory allocator when building ​​Redis​​ is done by setting

the `MALLOC` environment variable. Redis is compiled and linked against libc

malloc by default, with the exception of jemalloc being the default on Linux

systems. This default was picked because jemalloc has proven to have fewer

fragmentation problems than libc malloc.


To force compiling against libc malloc, use:


% make MALLOC=libc


To compile against jemalloc on Mac OS X systems, use:


% make MALLOC=jemalloc



说关于分配器allocator， 如果有MALLOC 这个 环境变量， 会有用这个环境变量的 去建立Redis。


而且libc 并不是默认的 分配器， 默认的是 jemalloc, 因为 jemalloc 被证明 有更少的 fragmentation problems 比libc。


但是如果你又没有jemalloc 而只有 libc 当然 make 出错。 所以加这么一个参数。

解决办法

make MALLOC=libc
