使用GD和libjpeg支持编译PHP

Question

I compile my own PHP, partly to learn more about how PHP is put together, and partly because I'm always finding I need modules that aren't available by default, and this way I have control over that.

My problem is that I can't get JPEG support in PHP. Using CentOS 5.6. Here are my configuration options when compiling PHP 5.3.8 :

 './configure'  '--enable-fpm' '--enable-mbstring' '--with-mysql' '--with-mysqli' '--with-gd' '--with-curl' '--with-mcrypt' '--with-zlib' '--with-pear' '--with-gmp' '--with-xsl' '--enable-zip' '--disable-fileinfo' '--with-jpeg-dir=/usr/lib/'

The ./configure output says:

checking for GD support... yes
checking for the location of libjpeg... no
checking for the location of libpng... no
checking for the location of libXpm... no

And then we can see that GD is installed, but that JPEG support isn't there:

# php -r 'print_r(gd_info());'
Array
(
    [GD Version] => bundled (2.0.34 compatible)
    [FreeType Support] =>
    [T1Lib Support] =>
    [GIF Read Support] => 1
    [GIF Create Support] => 1
    [JPEG Support] =>
    [PNG Support] => 1
    [WBMP Support] => 1
    [XPM Support] =>
    [XBM Support] => 1
    [JIS-mapped Japanese Font Support] =>
)

I know that PHP needs to be able to find libjpeg, and it obviously can't find a version it's happy with. I would have thought /usr/lib/libjpeg.so or /usr/lib/libjpeg.so.62 would be what it needs, but I supplied it with the correct lib directory ( --with-jpeg-dir=/usr/lib/ ) and it doesn't pick them up so I guess they can't be the right versions.

rpm says libjpeg is installed. Should I yum remove and reinstall it, and all it's dependent packages? Might that fix the problem?

Here's a paste bin with a collection of hopefully useful system information:

Answer 1

as requested:

Sometimes the configure script is dumb, and you have to do --with-somelib=/usr instead of ...=/usr/lib, because the config test is written as providedpath + '/lib/' rather than just providedpath internally. You may have to dig around inside the configure test suite to find out what's really required

Answer 2

Don't forget to do a

make clean

after you configure.

I've got make some other configuration and make before and the old installation prevent me to got the jpeg support enabled on GD.

It saves me on ubuntu 12.04 64bits

I've also use these packages :

aptitude install libjpeg62-dev libpng-dev libfreetype6-dev

with this configure options:

./configure \
  --with-config-file-path=/usr/local/apache2/conf \
  --with-jpeg-dir \
  --with-png-dir \
  --with-vpx-dir \
  --with-freetype-dir \
  --enable-apc \
  --enable-bcmath \
  --enable-calendar \
  --enable-dba \
  --enable-exif \
  --enable-ftp \
  --enable-mbstring \
  --enable-shmop \
  --enable-sigchild \
  --enable-soap \
  --enable-sockets \
  --enable-sysvmsg \
  --enable-zip \
  --enable-gd-native-ttf  \
  --with-gd \
  --with-apxs2=/usr/local/httpd/bin/apxs \
  --with-bz2 \
  --with-curl \
  --with-gettext \
  --with-mcrypt \
  --with-mysql-sock=/var/run/mysqld/mysqld.sock \
  --with-openssl \
  --with-pdo-mysql \
  --with-xmlrpc \
  --with-zlib

and then :

make clean
make
make install

Run good with Apache 2.4.3 and PHP 5.4.11

Answer 3

You most probably need to install the development version, not the run-time version, of libjpeg (of course, the run-time version will be needed once you've compiled).

I don't use CentOS myself, but something like this should help:

rpm install libjpeg-devel

I might have the package name wrong, but look for something with a -dev or -devel postfix.
