redis 2.6.9 安装报错

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

解决办法是：

make MALLOC=libc

zmalloc.o: In function `zmalloc_used_memory’:  

/root/redis/redis-2.6.13/src/zmalloc.c:223: undefined reference to `__sync_add_and_fetch_4′ 

collect2: ld 返回 1  

make[1]: *** [redis-server] 错误 1  

make[1]: Leaving directory `/root/redis/redis-2.6.13/src’  

make: *** [all] 错误 2  

之后再做 2 件事：

     ① 在src/Makefile开头加 CFLAGS= -march=i686

     ② 编辑src/.make-settings里的OPT，改为OPT=-O2 -march=i686
