Hi

i'm trying to add thumbnail images in my mediawiki wiki on linux mandrake 9.0 however if i view the image as full size it displays it no prob. However as a thumb i get the message

Incomplete GD library configuration: missing function imagecreatefromjpeg

so i tried downloading gd-2.0.34 unzipped it and ran

./configure
make
make install

and it appears to have installed ok. however the problem still remains and i can't view the thumbnails.

can anyone help?

Thanks Matt.

Do you have gd enabled in PHP? If not you can probably install it with your distros package manager.

not sure how would i check whether or not i've got gd enabled in PHP?

matt

Create a file named info.php with the contents of:

<?php

phpinfo();

?>

Then put the file in your webroot directory and open it in your browser:

http://servername/info.php

You should see a page with details about your PHP install. If you have gd installed with PHP you should see a Section called GD and it should say it's enabled.

thanks for the reply.

there is no gd section in i assume i must have installed the gd library wrongly? can anyone help me do this then? as i dont want to risk bringing the wiki down.

heres the output to info.php

Which Distro are you using? From your first post I assume you compiled gd yourself, did you compile PHP as well? If you did compile PHP all you'll have to do is recompile it wich shouldn't affect the running wiki.

If you're going to recompile PHP to enable gd do a:

And look for gd in the output. There should be something like --with-gd=path_name so when you do your ./configure it'll be something like:

Once you've recompiled you'll just need to restart Apache to use the new PHP binaries with gd support.

If you're using a rpm based distro you should be able to install a package that already enables gd look for something like php-gd.

Hi yes i didnt copile and install php 5.2.0 myself.

i've begun to recompile php again however i get this error now and wonder if you know wha it means. I pulled this ./configure line from the media wiki website.
'./configure' '--with-mysql' '--without-sqlite' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-zlib' '--with-ldap' '--with-gd' '--with-jpeg-dir=/usr/local/lib' '--with-iconv-dir' '--enable-mbstring'

and i changed the apxs2 to be '--with-apxs2=/usr/sbin/apxs2'

when i use this config i get the error

configure: error: libjpeg.(a|so) not found.

now i have downloaded and installed libjpeg-6b and done the following

./configure
make install

this seems to have installed the libjpeg librar. however i still get the error.

Thanks Matt.

Is this where you installed libjpeg?

'--with-jpeg-dir=/usr/local/lib'

If not you should point it to where you compiled it. Do you really need libjpeg? If not I'd try removing that entry and just going with what you know you absolutely need.

Once you have it working and you find out you do need some extra functionality you can always recompile with the correct flags. My advice is to document which flags you do use so if you do need to recompile later you won't miss them.

thanks for the reply.

yes i have tried using the /usr/local/lib and also /usr/lib/bin (this was where the make install seemed to be putting the files, bearing in mind i simply used all the deefault options i.e.

./configure
make install

i didnt want to remove them as i thought they may be needed to get my problem solved. ok ive removed the --with-jpeg-dir=/usr/local/lib'. I now get the following error

If configure fails try --with-jpeg-dir=<DIR>
configure: error: libpng.(a|so) not found.

so i changed '--with-gd' to be '--with-gd=/usr/local/include' (where the gd.h file is held which i found using find command)

i then get the following

configure: error: Unable to find libgd.(a|so) anywhere under /usr/local/include

any ideas?

Matt

just to update i downloaded the libpng package and have installed this and now get the error

configure: error: Cannot find ldap.h

when trying to configure php

any ideas to get around this?

That's the options for LDAP support. If you don't need it don't put in the following:

'--with-ldap'

If you do need LDAP support in PHP then you'll need to install OpenLDAP or another LDAP server that PHP works with. I'm really only familiar with OpenLDAP, but I'd think others would be supported. Anyway, you probably don't have it enabled now so I'd just disable it and see if it will build.

Ok. i've removed this. i did download the openldap package but it was asking for some kind of db to be installed also so thought i shoul check with you before i went aheaqd installing it all. Just in case my stupidness brought the wiki down. what exactly is the openldap for?

again i wasnt sure if this would be needed to help solve my problem. i did configure again without this

'./configure' '--with-mysql' '--without-sqlite' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-zlib' '--with-gd' '--with-iconv-dir'

and got the following error

configure: error: Cannot find MySQL header files under yes.
Note that the MySQL client library is not bundled anymore!

so i changed the config to

'./configure' '--with-mysql=/usr/local/mysql' '--without-sqlite' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-zlib' '--with-gd' '--with-iconv-dir'

which configured no problem.

i then ran

make
make install

restarted apache

/usr/local/apache2/bin/apachectl restart

however when i then use the wiki the problem still remains on my thumbnail? any ideas.

thanks matt.

Mmmmm...You might make sure gd is enabled by going back to the info.php file you setup earlier. The other thing you might try it to change your '--with-gd' to:

And then see if the thumbnails work.

OpenLDAP is an open source LDAP server. LDAP stands for Light Weight Directory Access Protocol. Basically it's another way to authenticate users, and also store user information such as name, address, email, etc. If your storing all your user information in the MySQL database then at this time you really don't need to enable it.

hi i compile the gd using the defualts, i.e. ./configure, make, make install

i then use the following to configure php

'./configure' '--with-mysql=/usr/local/mysql' '--without-sqlite' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-zlib' '--with-gd=/usr/local/' '--with-iconv-dir'

this compile ok however when i make php i get the error

(i supplied a bit of the print out too) its seems to not find the gd library. any ideas?

Okay I think you've got the wrong directory for your "--with-gd=/usr/local". You'll need to specify the directory where the gd library files are. There should be an "include" directory when you installed gd.

Check somewhere under /usr/local/lib for file. There will probably be version numbers at the end of it. Where ever that file is put that directory in your --with-gd= argument:
