./configure '--with-apxs2=/usr/local/apache2/bin/apxs' '--enable-calendar' '--enable-mbstring' '--disable-cgi' '--disable-magic-quotes' '--with-curl' '--with-curlwrappers' '--with-zlib' '--with-bz2' '--enable-ftp' '--with-gd' '--with-mcrypt' '--with-mhash' '--with-mysql=/usr/lib/mysql' '--enable-soap' '--with-xmlrpc' '--enable-zip' '--with-pear'

and the error you receive is:

/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

Most probably you don’t have libtool-ltdl-devel installed. All you need is to install it using yum (or any other applicable package manager). yum install libtool-ltdl-devel. Then run ./configure, make and make install. This should do the job.

First of all, we need to ensure we’ve got Imagemagick on our server. Please, read my previous post, where the procedure of Imagemagick setup is explained, if you don’t have it installed. You need to install Imagemagick first in order to add its functions in PHP, I hope it’s clear.

After the main library is installed, we will need another source archive, that will allow us to add Imagemagick functions to PHP. This package is called Imagick, and you’re welcome to select one package you like. I’ve taken 3.0.0b2 beta, the most recent for today.

Let’s download it to our server:

wget http://pecl.php.net/get/imagick-3.0.0b2.tgz

Extract to a folder:

tar -xzvf imagick-3.0.0b2.tgz

cd into this folder

cd imagick-3.0.0b2;

Then we need to run phpize

phpize

Then our usual list of commands:
./configure –with-imagick=/usr/local
make
make install

After you’ve built imagick, you should see something like this:

Now you need to copy the created library named imagick.so to your extensions directory. However you can skip this step, if you like to deal with ling paths in your php.ini.

And the final stage is to add imagick module to php.ini. If you have copied the library to your extensions directory, you should add the following line to php.ini:

extension=imagick.so

If you have decided to keep the library at the place where it was installed, the string will look like

extension=/usr/local/lib/php/extensions/no-debug-non-zts-20060613/imagick.so

Now restart Apache and check your phpinfo(). If everything is OK, you should see:

You should now be able to use Imagemagick functions. Feel free to ask me any questions you have.

First of all, we need to download the Ioncube package. Just choose your operating system and download an archive to your place. Then you need to extract it.

tar -xzvf ioncube_loaders_lin_x86.tar.gz

I would suggest you to copy extracted files to a safe location so you could point to it when adding support lines to php.ini.

It will be much easier if ioncube loader helper page is accessible from the web, just like here: http://www.lampdocs.com/blog/ioncube/ioncube-loader-helper.php?page=install-assistant . Helper will detect the place where your php.ini is located and will suggest the correct path. If you don’t have web access to helper page, you’re welcome to follow my post finding php.ini file location.

To install the Loader in your php.ini file, edit or create php.ini file by the path specified by loader and add the following line before any other zend_extension lines:

zend_extension = /
/ioncube_loader_lin_5.2.so

where /
/ is where you’ve installed the loader, e.g. /usr/local/ioncube/. Make sure this line is added before any other zend_extension lines, as you might have troubles starting Apache. Here is how it looks on my server:

[Zend]
zend_extension=/usr/local/ioncube/ioncube_loader_lin_5.2.so
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.3
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3
zend_optimizer.version=3.3.3

zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so

After that you must restart apache to activate your changes. You should not experience problems starting it, and your ioncube installation should be ready to use. If not, you’re welcome to ask me here.

cat `ls /etc/*{-,_}{release,version} 2>/dev/null | head -n 1`

This will show you something like

The picture below shows the difference between common commands: one shown above and uname -a. Sometimes you don’t need the kernel version, just the operating system name. This command should help you to do that.

The issue is described at PHP Bugs.  There is no exact solution there that’s why I decided to create this guide.

I’ve found that the issue was found after a recent PHP update using Directadmin custombuild script. I’ve got all recent software, but PHP doesn’t recognize simple symbols. My first thought was that the problem is with XML interpretation, that is especially related to libxml2. I’ve followed Directadmin forums and thought the problem is with libxml2 version.  I’ve tried to update it to version 2.7.3. There was no success as the problem still continued to persist.

#cd /usr/local/directadmin/custombuild
#wget http://xmlsoft.org/sources/libxml2-2.7.3.tar.gz
#tar -zxvf libxml2-2.7.3.tar.gz
#cd libxml2-2.7.3
#./configure –with-iconv=/usr/local
#make
#make install

This step itself doesn’t help, but you need to do it in order to fix the entire problem.

The second step you need to make is to build php with libexpat. In order to do this, you will need to perform the following steps:

- install expat-devel by entering  yum install expat-devel.

- add expat support to your PHP build. In order to do this (I assume you’re using custombuild to build PHP), you have to edit /usr/local/directadmin/custombuild/configure/ap2/configure.php5.  –with-libexpat-dir=/usr is the string you need to end to your current file contents.

Then you need to update  the PHP version in /usr/local/directadmin/custombuild/versions.txt to 5.2.8 (most current version at the moment). After that you have to build PHP again.

cd /usr/local/directadmin/custombuild
./build php

There is no need to build anything but PHP that’s why I’ve said No to all other proposals (like cURL, Freetype, etc).  As Apache is restarted automatically, you just have to wait while the build process is complete. After that you’re welcome to enjoy your new PHP installation.

First of all you need to know where your PHP installation is located. I think you already have it installed if you are going to add some functions. Try searching for your PHP package (I mean installing PHP from source in this article) at your server: it should exist.

When you have the package near and know where it is located, you should identify your current configuration to avoid deleting some elements from the configure line. The most useful method is to copy your current configure line from the output produced by phpinfo(); You may create a new file containing just these lines:

<?
phpinfo();
?>

Then run it using a web browser. At the beginning of this output you should see a configure line: it should look like:

‘./configure’ ‘–with-apxs2′ ‘–with-curl=/usr/local/lib’ ‘–with-gd’ ‘–enable-gd-native-ttf’ ‘–with-ttf’ ‘–with-gettext’ ‘–with-jpeg-dir=/usr/local/lib’ ‘–with-freetype-dir=/usr/local/lib’ ‘–with-kerberos’ ‘–with-openssl’ ‘–with-mcrypt’ ‘–with-mhash’ ‘–with-mysql=/usr’ ‘–with-mysqli=/usr/bin/mysql_config’ ‘–with-pear’ ‘–with-png-dir=/usr/local/lib’ ‘–with-zlib’ ‘–with-zlib-dir=/usr/local/lib’ ‘–enable-zip’ ‘–with-iconv=/usr/local’ ‘–enable-bcmath’ ‘–enable-calendar’ ‘–enable-ftp’ ‘–enable-magic-quotes’ ‘–enable-mbstring’ ‘–enable-pcntl’

Copy it to your text editor and remove quotes and apostrophes. Then add ‘–enable-sockets’ to this line: that’s the only string we need to enable socket support.

Then we need to make PHP. If you’re doing it for the first time, see my previous post: How to configure PHP .

The command is simple enough: make . I’d suggest you to make clean before doing make to avoid some possible errors. After the PHP is  “made” you need to make install and then to reboot Apache or any web server you might have to see the changes.  If everything went OK, you should see that socket functions are now available.

As we’re dealing with a non-rpm system, we’ll have to install all the software we need from sources. In order to support hash algoritms we need to install libmhash. Just download it, extract with the following command:

tar -xzvf mhash-0.9.9.tar.gz

and go to the extracted directory:

cd mhash-0.9.9

Then you will use the usual combination for linux:

./configure
make
make install

Then you will need to recompile PHP with

–with-mhash

If you don’t know how to recompile PHP,  just search this blog as it contains lots of information on installing and configuring PHP.

First of all we need to log in as root and go to /usr/local/directadmin/customapache.

cd /usr/local/directadmin/customapache

You should find configure.php_ap2 or configure.php files, depending on Apache version that is build using this Directadmin build system. I’ve got both these files. In order to add iconv support we need to add the following line to these files:

–with-iconv

Just take a look at my file.

Then we need to go to the command line to the same directory to run our build script. The string will look like

[root@lampdocs customapache]# ./build php_ap2

If your Apache version is lower than 2 (for example, 1.4), your string will be:

[root@lampdocs customapache]# ./build php

It will ask you to rebuild the software you have, you don’t really need it. You won’t need to add any configure lines: the script will do this for you. make and make install will be done automatically.  Don’t forget to reboot Apache (service httpd restart) and have fun!
