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

解决办法：
vim Makefile
加入

#ifndef SSIZE_MAX
# define SSIZE_MAX      32767
#endif

解决办法
vim Makefile

CFLAGS = -Wall -g -O2 -I/usr/local/include $(M64)

改为：

CFLAGS = -lrt -Wall -g -O2 -I/usr/local/include $(M64)
