Call to undefined function imagecreatefromjpeg()
默认的php安装后gd不支持jpg，只支持gif、png、bmp

之前我曾经解决过，不过当时没留笔记，这次折腾了一天才弄出来，当一个教训吧。
隐约记得之前我配的没这么麻烦，如果你知道更简单的方法，请给我留言，先谢谢了。
重新安装gd

wget http://www.boutell.com/gd/http/gd-2.0.33.tar.gz tar zxvf gd-2.0.33.tar.gz cd gd-2.0.33 ./configure --prefix=/usr/local/gd2 make make instal |
重新编译php，指定gd2安装目录，如果不指定目录会在configure是报错

编译php

编译时php5.4.7 安装出现 error: ‘struct gdIOCtx’ has no member named ‘data’
ext/gd/gd_ctx.c:67:8: error: ‘struct gdIOCtx’ has no member named ‘data’
解决方法：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:
https://bugs.php.net/bug.php?id=55224
https://bugs.php.net/bug.php?id=60108
个人采用的方法：
vi <gd_dir>/include/gd_io.h
gdIOCtx结构中增加void *data;
gdparttopng.c:42: undefined reference to `gdImageCreateFromGd2Part’
yum install libjpeg-devel freetype-devel libpng-devel
make clean后重新./configure
make&make install

虽然没有版本号，但是imagecreatefromjpeg()可以使用了。
终于有jpeg了
做好之后又出现了新问题，说没有可以被缩略的图像资源
我的是这个错误 是什么原因呢 PHPinfo 里面都是支持的呢 Call to undefined function imagecreatefrombmp()
