yum install libevent-devel libevent
mkdir magent
cd magent/
tar-zxf magent-0.6.tar.gz
/sbin/ldconfig
sed -i "s#LIBS = -levent#LIBS = -levent -lm#g" Makefile
make
cp magent /usr/bin/magent
0.6make错误多，可用0.5版
安装时错误解决方法
make时报错
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：
vim ketama.h
在开头加入
#ifndef SSIZE_MAX
#define SSIZE_MAX 32767
#endif
再次make报错：
gcc: /usr/lib64/libevent.a: No such file or directory
gcc: /usr/lib64/libm.a: No such file or directory
解决：
vi Makefile
找到 LIBS = /usr/lib64/libevent.a /usr/lib64/libm.a这一行
将libevent 的安装路径修改为/usr/local/lib/ libevent.a
或者ln-s/usr/local/lib/libevent*/usr/lib64/
ln-s/usr/lib64/libm.so /usr/lib64/libm.a
再次make报错:
/usr/local/lib/libevent.a(event.o): In function`gettime':
undefined reference to `clock_gettime'
collect2: ld returned 1exit status
解决：
vim Makefile
将
CFLAGS = -Wall-g-O2 -I/usr/local/include $(M64)
改为：
CFLAGS = -lrt-Wall-g-O2 -I/usr/local/include $(M64)
删除临时文件rm -rf *.o后
再次make成功生成magent
最后cp magent /usr/bin/magent
