编译redis的时候出现zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory问题的解决办法

1.编译redis的时候 出现了下面的错误
[root@db01 redis]# make && make install
cd src && make all
make[1]: Entering directory /opt/redis_cluster/redis-3.2.9/src' CC adlist.o In file included from adlist.c:34:0: zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory #include ^ compilation terminated. make[1]: *** [adlist.o] Error 1 make[1]: Leaving directory/opt/redis_cluster/redis-3.2.9/src’
make: *** [all] Error 2

2.我以为是我没安装gcc
yum install gcc gcc-c++ -y 但是再编译也还是一样的问题

3.解决办法
make MALLOC=libc
make install

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
