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


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:
Array
(
\[0] => yp
[1] => xml
[2] => wddx
[3] => tokenizer
[4] => sysvshm
[5] => sysvsem
[6] => standard
[7] => sockets
[8] => shmop
[9] => session
[10] => pspell
[11] => posix
[12] => pcre
[13] => overload
[14] => mime_magic
[15] => iconv
[16] => gmp
[17] => gettext
[18] => ftp
[19] => exif
[20] => dio
[21] => dbx
[22] => dba
[23] => curl
[24] => ctype
[25] => calendar
[26] => bz2
[27] => bcmath
[28] => zlib
[29] => openssl
[30] => apache2handler
[31] => mysql
)

The complete ./configure options for php were:

./configure --build=i686-redhat-linux-gnu --host=i686-redhat-linux-gnu --target=i386-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --cache-file=../config.cache --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --enable-force-cgi-redirect --disable-debug --enable-pic --disable-rpath --enable-inline-optimization --with-bz2 --with-db4=/usr --with-curl --with-exec-dir=/usr/bin --with-freetype-dir=/usr --with-png-dir=/usr --with-gd=shared --enable-gd-native-ttf --without-gdbm --with-gettext --with-ncurses=shared --with-gmp --with-iconv --with-jpeg-dir=/usr --with-openssl --with-png --with-pspell --with-xml --with-expat-dir=/usr --with-dom=shared,/usr --with-dom-xslt=/usr --with-dom-exslt=/usr --with-xmlrpc=shared --with-pcre-regex=/usr --with-zlib --with-layout=GNU --enable-bcmath --enable-exif --enable-ftp --enable-magic-quotes --enable-sockets --enable-sysvsem --enable-sysvshm --enable-track-vars --enable-trans-sid --enable-yp --enable-wddx --with-pear=/usr/share/pear --with-imap=shared --with-imap-ssl --with-kerberos --with-ldap=shared --with-mysql=shared,/usr --with-pgsql=shared --with-snmp=shared,/usr --with-snmp=shared --enable-ucd-snmp-hack --with-unixODBC=shared,/usr --enable-memory-limit --enable-shmop --enable-calendar --enable-dbx --enable-dio --enable-mbstring=shared --enable-mbstr-enc-trans --enable-mbregex --with-mime-magic=/usr/share/file/magic.mime --with-apxs2=/usr/sbin/apxs

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.

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?

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

normal /var/lib/php
normal /var/lib/php/session

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

drwxr-xr-x 2 1000 1000 4096 Jan 12 2006 tests

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

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.

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?

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

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.
