已安装Gd,但"调用未定义的函数imagecreatefromjpeg()"

Question

看起来我的主机有gd支持,但我仍然收到错误(PHP版本5.3.28)

Fatal error: Call to undefined function imagecreatefromjpeg()

这是我的phpinfo:

gd

GD Support  enabled
GD Version  bundled (2.1.0 compatible)
GIF Read Support    enabled
GIF Create Support  enabled
PNG Support enabled
libPNG Version  1.2.44
WBMP Support    enabled
XBM Support enabled

Directive   Local Value Master Value
gd.jpeg_ignore_warning  0   0

Answer 1

看来虽然确实支持GD,但它没有用libjpeg编译.该gd.jpeg_ignore_warning并不能意味着你必须支持JPEG.如果这是您自己的服务器,请确保运行configure with --with-jpeg-dir.您可能需要搜索它.我使用了命令find / -name libjpeg*并获得/usr/lib了CentOS5.如果这是共享主机让他们为您安装它.

我完整的PHP编译如下:

wget http://us1.php.net/distributions/php-5.5.10.tar.gz -O php.tar.gz 
tar -xvf php.tar.gz
cd php-5.5.10
yum -y install libxml2-devel libmcrypt-devel libpng-devel
./configure --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d  --with-apxs2 --with-mysql --with-mysqli --with-zlib --with-curl --with-libdir=lib --with-openssl --with-pdo-mysql --with-mcrypt  --with-pcre-regex --enable-zip --with-gd --enable-mbstring --with-jpeg-dir=/usr/lib
make clean
make 
make install
