在安装php时，报如下错误

好像说这个错误算是php5.4的bug，下面对应的两篇文章有对应的说明:

解决方法
vi <gd_dir>/include/gd_io.h
gdIOCtx结构中增加void *data;
格式如下
typedef struct gdIOCtx
{
int (*getC) (struct gdIOCtx *);
int (*getBuf) (struct gdIOCtx *, void *, int);
void (*putC) (struct gdIOCtx *, int);
int (*putBuf) (struct gdIOCtx *, const void *, int);
/* seek must return 1 on SUCCESS, 0 on FAILURE. Unlike fseek! */
int (*seek) (struct gdIOCtx *, const int);
long (*tell) (struct gdIOCtx *);
void (*gd_free) (struct gdIOCtx *);
void (*data);
}
gdIOCtx;
