Compiling PHP with GD and libjpeg support
- by Robin Winslow
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:
