一、编译安装GD库时出现的错误

报错信息如下:

gd_png.c:603: error: ‘PNG_COMPRESSION_TYPE_DEFAULT’ undeclared (first use in this function) gd_png.c:

609: error: ‘PNG_COLOR_TYPE_RGB’ undeclared (first use in this function) gd_png.c

725: error: ‘row_pointers’ undeclared (first use in this function) gd_png.c

解决办法:

进入gd源代码目录:/opt/ws/gd2

vim      gd_png.c

将16行的png.h修改成         libpng安装目录/include/png.h(/opt/ws/libpng/include/png.h)

make  && make install

 

二、报错信息如下:

/root/lamp/php-5.4.1/ext/gd/gd_ctx.c: In function ‘_php_image_stream_putc’:
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c:51: error: ‘struct gdIOCtx’ has no member named ‘data’
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c: In function ‘_php_image_stream_putbuf’:
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c:58: error: ‘struct gdIOCtx’ has no member named ‘data’
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c: In function ‘_php_image_stream_ctxfree’:
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c:67: error: ‘struct gdIOCtx’ has no member named ‘data’
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c:68: error: ‘struct gdIOCtx’ has no member named ‘data’
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c:69: error: ‘struct gdIOCtx’ has no member named ‘data’
In file included from /root/lamp/php-5.4.1/ext/gd/gd.c:103:
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c: In function ‘_php_image_output_ctx’:
/root/lamp/php-5.4.1/ext/gd/gd_ctx.c:153: error: ‘gdIOCtx’ has no member named ‘data’
make: *** [ext/gd/gd.lo] Error 1
解决方法:
vim     /opt/ws/gd2/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;
