GD not loaded though compiled, resulting in "Call to undefined function"

czamora · 07-24-2006, 03:26 PM

Hi,

My current php installation (version 4.3.9) was built with GD:

--with-gd=shared --enable-gd-native-ttf --without-gdbm

but when I try to use any GD functions I get:

PHP Fatal error: Call to undefined function: imagefontheight()

GD is installed on my system (Linux Centos 4.3), as indicated by yum, and by the fact that Webmin uses it.

I have tried loading it as an extension, by including the line
extension=libgd.so
in a file inside /etc/php.d, but it does not find that library. If I link /usr/lib/php4/libgd.so to the actual library file in /usr/lib/libgd.so.2, then it complains that the file is not a php extension library.

I don't know what else to do, or what can be wrong.

Any help will be greatly appreciated.

get_loaded_extensions() gives:

[3] => tokenizer
[4] => sysvshm

The complete ./configure options for php were:

Try locating the actual .so file. When I installed it on Ubuntu I kept getting the exact same error that you are when I was trying to install eventum. All I did you fix that issue is located the actual gd.so and place a copy of it in the extensions directory. All so can you place what you got from phpinfo(). If you have not created that yet then do this.

Code:

<html>
<head>
<title>PHP Information</title>
</head>
<body>
<?phpinfo();?>
</body>
</html>

This will also let you know where you extension directory is.

czamora · 07-25-2006, 03:09 PM

The problem is I don't know what the name of the library file should be.

I have made a search for gd.so:

find / -name gd.so

and found nothing.
So I performed a more generic search:

find / -name "*gd*.so*"

and found

/usr/lib/libgd.so.2
/usr/lib/libgd.so
/usr/lib/libgdbm.so.2
/usr/lib/libgd.so.2.0.0
/usr/lib/python2.3/lib-dynload/gdbmmodule.so
/usr/lib/libgdbm.so.2.0.0

of which /usr/lib/libgd.so and /usr/lib/libgd.so.2 are links to /usr/lib/libgd.so.2.0.0

But that is the one that, when in my extensions directory, causes the error I mentioned:

PHP Warning: Unknown(): Invalid library (maybe not a PHP library) 'libgd.so.2.0.0' in Unknown on line 0

Oh, and the output of phpinfo() is too large to post it here. Any specific data you need?

jstephens84 · 07-26-2006, 10:04 AM

I would like to see where your extension directories are located. Also you might try and download php from the website and see if it comes with a module that can be loaded. If it does then just copy that to your extension directory.

The extensions directory for php would be /usr/lib/php4, as indicated in the php.ini file:

; Directory in which the loadable extensions (modules) reside.
extension_dir = /usr/lib/php4

In that directory I only have mysql.so

Regarding the downloading of php, I'm afraid the official site (php.net) only offers binaries for Windows. I have found on the net a non-source rpm, php-4.3.9-3.12.i386.rpm, but this is all it contains:

[root@site ~]# rpm -qps php-4.3.9-3.12.i386.rpm

So, no libraries there.

On the other hand, the source for php does seem to contain the code for gd:

[root@site php-4.4.2]# ls -l ext/gd

But I don't know how to compile that without a compile script.

jstephens84 · 07-26-2006, 05:24 PM

I would probably uninstall your php then use the source you downloaded then reinstall php. check the ./configure for all the options that you can use.

czamora · 07-27-2006, 05:50 AM

Yes, but I have done that already in a previous server and I had to leave it because it started failing and not executing php and nobody could find the reason, so I'm scared of installing things myself.

Furthermore, when I try ./configure for the php source it complains that Apache was not built with so support, so I would have to reinstall Apache too, and that's a lot of fuss (and exactly what I was forced to do in my previous server which went down).

Any ideas on how to fix the linking problem without having to reinstall php from source?

jstephens84 · 07-27-2006, 10:11 AM

Ok, I will try and research and look around for possible fixes.

czamora · 07-27-2006, 03:17 PM

Thanks a lot. I'll look forward to your advice.

jstephens84 · 07-27-2006, 03:31 PM

check to see what your ld.so.conf file has in it.

jstephens84 · 07-27-2006, 03:37 PM

See if any of this applies to you also. http://bugs.php.net/bug.php?id=36208

Just for everybody's reference, the solution, as pointed out at the centos.org forum, was simply to check for packages related to GD, with:

yum list *gd*

Then, I could see there is package called php-gd.i386 that was not installed on my system.

The only thing I had to do was to install that package:

yum install php-gd.i386

and restart Apache.

It worked like magic!

Thanks to all for your help anyways.
