安装magent到/usr/local/下


cd /usr/local
mkdir magent
cd magent/
wget http://memagent.googlecode.com/files/magent-0.6.tar.gz
tar zxvf magent-0.6.tar.gz
/sbin/ldconfig
sed -i "s#LIBS = -levent#LIBS = -levent -lm#g" Makefile
make

错误1:

    gcc -lrt -Wall -g -O2 -I/usr/local/include -m64 -c -o magent.o magent.c
    magent.c: In function ‘writev_list’:
    magent.c:729: error: ‘SSIZE_MAX’ undeclared (first use in this function)
    magent.c:729: error: (Each undeclared identifier is reported only once
    magent.c:729: error: for each function it appears in.)
    make: *** [magent.o] Error 1

解决的方法:
vi ketama.h


在开头增加
   
#ifndef SSIZE_MAX
# define SSIZE_MAX      32767
#endif

错误2:

    gcc -Wall -g -O2 -I/usr/local/include -m64 -c -o magent.o magent.c
    gcc -Wall -g -O2 -I/usr/local/include -m64 -c -o ketama.o ketama.c
    gcc -Wall -g -O2 -I/usr/local/include -m64 -o magent magent.o ketama.o /usr/lib64/libevent.a /usr/lib64/libm.a
    /usr/lib64/libevent.a(event.o): In function `gettime’:
    (.text+0×449): undefined reference to `clock_gettime’
    /usr/lib64/libevent.a(event.o): In function `event_base_new’:
    (.text+0x72a): undefined reference to `clock_gettime’
    collect2: ld returned 1 exit status
    make: *** [magent] Error 1

解决的方法
vim Makefile
   
CFLAGS = -Wall -g -O2 -I/usr/local/include $(M64)
改为:   
CFLAGS = -lrt -Wall -g -O2 -I/usr/local/include $(M64)


错误3:centos 6


[[email protected] magent]# make
gcc -Wall -g -O2 -I/usr/local/include -m64 -c -o magent.o magent.c
gcc -Wall -g -O2 -I/usr/local/include -m64 -c -o ketama.o ketama.c
gcc -Wall -g -O2 -I/usr/local/include -m64 -o magent magent.o ketama.o /usr/lib64/libevent.a /usr/lib64/libm.a
gcc: /usr/lib64/libm.a:没有那个文件或文件夹
make: *** [magent] 错误 1
解决的方法

ln -s /usr/lib64/libm.so /usr/lib64/libm.a

 

注:有可能还会报错 gcc: /usr/lib64/libevent.a: 没有那个文件或文件夹

假设有,可运行

vi Makefile


找到 LIBS = /usr/lib64/libevent.a /usr/lib64/libm.a

改动 LIBS = /usr/libevent 的安装路径/libevent.a /usr/lib64/libm.a

例: LIBS = /usr/lib/libevent.a /usr/lib64/libm.a

 

查看magent是否成功安装

cd usr/bin/magent ./magent


please provide -s "ip:port" argument
