redis make报错

1. 解压redis后，第一次make出现报错：

[root@localhost redis-3.2.5]# make cd src && make all
make[1]: Entering directory `/data/redis/redis-3.2.5/src'

1.  安装gcc后，继续make出现如下报错：

[root@localhost redis-3.2.5]# make
cd src && make all
make[1]: Entering directory `/data/redis/redis-3.2.5/src'
CC adlist.o
In file included from adlist.c:34:0:

compilation terminated.
make[1]: *** [adlist.o] Error 1
make[1]: Leaving directory `/data/redis/redis-3.2.5/src'
make: *** [all] Error 2

解决方法：

第一种：执行 make MALLOC=libc 命令 ，如果执行后报错 或 还有其他错误,建议删除redis所有文件重新解压编译尝试

原因：由于系统没有jemalloc 而只有 libc ，但是默认回去找jemalloc，导致了 make 出错。 所以加参：make MALLOC=libc

第二种：make CFLAGS="-march=x86-64"       

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

 

在构建Redis时，通过设置来选择非默认的内存分配器

MALLOC的环境变量。Redis被编译并链接到libc

malloc是默认的，jemalloc是Linux上的默认值。之所以选择这个默认值，是由于事实证明jemalloc的内存更少，碎片化问题比libc malloc严重。

现在由于没有jemalloc 而只有 libc ，但是默认回去找jemalloc，导致了 make 出错。 所以加这么一个参数。  

要强制编译libc malloc，请使用:

% MALLOC = libc

要在Mac OS X系统上编译jemalloc，请使用:

% MALLOC = jemalloc
