Documenting my struggles to help others and hopefully get some feedback on how I could have done it better.
The command pecl install pthreads fails due to the php installed on my ubuntu 13.04 box not having zts configured.
Options:
1) The ubuntu respository does not have a php package with zts enabled. As of this post, ubuntu only has php 5.4.9 in it's repository (Released: 22 Nov 2012). It is possible to compile a php version from source - which I eventually did (see below), but..
2) I .. ALSO .. wanted to use phpfarm for the ability to run different versions of PHP on my local setup. On github, there is Christian Weiske's original contribution here (phpfarm) and a fork that he has contributed to, by François Poirotte - also called phpfarm. Francois' fork has a few more options to configure ('post-install customization') but I was not able to make that work with a PECL extension. I'm curious to know if misunderstood how to do that, because it looks to me that it just simply does not take PECL commands.
3). Prior to recompiling php from source, I loaded phpfarm (tried both versions), enabled php-fpm (FastCGI) and was able to get my apache2 server to use a phpfarm version (5.5.10) which showed up in a phpinfo() output. But the php-cli always showed the original php version (5.4.9) in the cli (run: php -v). Running (run: php -i | grep php.ini) showed /etc/php5/cli but I had previously removed php5 and aptitude show php5 returned a state of 'not installed.' I even renamed the /etc/php5 directory to see if I could force the system to use the phpfarm php version. Obviously, this is incorrect thinking and I went on to simply compile php 5.6 from source. But, is there something more to do to get a phpfarm php to be used in the cli? I read that the cli loads it's configuration file on a per command basis, unlike the apache2. If I could have run the 5.5.10 version (configured with zts) then I could have then done pecl install pthreads and then re-complied the phpfarm 5.5.10 version with pthreads enabled. Although it appears I will be able to run various versions of php in the apache server, will I ever be able to switch-phpfarm to another version and see it working in the php-cli? Also, I was uncertain on where I could have loaded a pthreads file for the phpfarm compile process to find and use it; could I have done it that way?
4) This stackoverflow post, essentially posted by Joe Watkins - the developer of pThreads is a perfect how-to on getting pThreads installed on a Ubuntu system that has had php configured with zts (Zend Thread Safety). (Thanks Joe!)
A nice tutorial on using phpfarm configured with fast-cgi and the apache server to help run websites under different php configurations.
So what gives with php, php-cli and the phpfarm?
I'm not sure about phpfarm, but do know of another solution ...
Multi
A tool for maintaining multiple installations of PHP in multiple configurations
https://github.com/datingvip/multi
This is a bit more user orientated, will allow you to build many configurations and versions of php, any tagged release of php, and any patched version from any fork of php-src.
In addition, because I wrote it, it will install pthreads for you.
git clone https://github.com/datingvip/multi
cd multi
VERSION=5.5.10 DBG=no-debug ZTS=zts ./php.multi
The above commands will yield an installation of PHP (in one suitable configuration, of one version) in /opt/php.
Look at php.defaults for configuration options and adjust before building
Should configuration fail on, for example, something related to a library like libxml2, it will usually be the case that
sudo apt-get install library-dev
Where library is replaced with the name of the library holding up the build, will fix the problem for you. If it does not, a quick google should get you going again.
Once the build is complete
source /path/to/multi/php.env 5.5.10
Note: multi will always install pthreads for any zts version automatically
I hope that gets you somewhere ...

I have problems with the Pthreads PHP extension. I have compiled PHP with ZTS enabled (--enable-maintainer-zts) and installed the pthreads via pecl and also tried to manually compile the extension.
It seems I don't actually know how to use it. I assumed I would be able to use the Thread class in PHP like any other built-in class, but with no luck as PHP doesn't recognize it. POSIX functions seem to work.
I am using Ubuntu 12.10 Server 64-bit with mod_php 5.4.6.
If you cannot access the extensions classes then it is not loaded.
I think you opened a bug report, to which I responded that your configure line is malformed.
The configure line you want to use is:
./configure --enable-pthreads --enable-maintainer-zts
The above command will build pthreads as a DSO.
./configure --enable-pthreads=static --enable-maintainer-zts
The above command will build pthreads statically into PHP.
Both are equally supported by 5.3, 5.4 and even 5.5.
Additionally, if you are overwriting your system installation then you should use a specific --prefix, for example, if you php executable is at /usr/bin ( which you can ascertain with "which php" ), then --prefix=/usr will overwrite your system installation.
Clean out your old installations ( do make uninstall if the sources are still available ). Start again, ensure you are either, overwriting the system installation or isolating this one completely.
Please update the bug report when you have worked it out.
I need the MongoDB PHP driver on my CentOS 5.4 machine. My PHP version is 5.1.6. I downloaded the RPM and installed it. That created several files in /usr/bin directory. I copied
/usr/bin/mongo
to
/usr/lib/php/modules
which was what extension_dir showed on doing phpinfo();.
I also added
extension=mongo.so
in /etc/php.ini.
However on executing my PHP script, i still get
Mongo class not found.
What's going wrong here ?
Also, my phpinfo() shows PHP version 5.1.6 whereas running PHP from command line shows 5.3.3. Could anything be wrong with that ?
Thanks in advance.
You're saying your webserver and command line PHP report different versions. These are going to be installed in different locations, and their extensions are API incompatible with each other.
When you installed the php_mongo extension, it may have used the command line php to determine the directory to install the extension to.
Make sure you have the correct php_mongo for the php version of your webserver, and it is in the correct extensions directory. (get the directory from the php.ini returned by phpinfo())
I hope you realise PHP 5.1 is also many years out of date. Unless you have a specific reason to use a version that old, you should also look at upgrading to a more recent version.
Edit:
Just read your comment "I must also mention that /usr/bin/mongo is a binary executable file but its not having a .so extension. Im copying it as is to /usr/lib/php/modules"
No no no! :)
This is the mongo command line client. This is not the PHP extension!
You can run a find /* -name "mongo.so" to see where the installer put the file, this will probably also give you an indication of which version of PHP it was installed for.
It looks as though you are confusing the RPM-packages for the MongoDB server with the requirements to install the MongoDB PHP driver. The PHP driver provides access to the server from your PHP applications, and does not install any command line tools.

I am trying to compile the imagemagick (imagick) extension to use in a non-thread-safe environment on windows.
I am using PHP 5.3.10 and have set up Visual C++ express as my compiling environment.
The problem is that I am using a non-thread-safe version of PHP as a FCGI module in Apache 2.2.
Thus, my PHP is supplied with a php5.lib and not a php5ts.lib. I believe this is the reason why I am getting these errors:
imagick.obj : error LNK2019: unresolved external symbol __imp__tsrm_mutex_alloc referenced in function _zm_startup_imagick
I have only ever built and compiled things on linux, so am not too sure how to do this on a windows environment.
How can I compile the extension so that it is non-thread-safe?
I downloaded the threadsafe binary of PHP 5.3.10 to get a copy of php5ts.lib. I was then able to compile the extension.
I am guessing that setting the ZTS preprocessor directive to either 1 or 0 would cause the extension to compile as either threadsafe or non-thread-safe. (Not too sure about this, so if someone could let me know if this is correct or not, it would be much appreciated. :) )
I then set up a virtual machine running Windows 7 and installed the latest version of WAMP. Reason being that it used a threadsafe version of PHP.
I placed the dll in the ext folder in the PHP installation and enabled it in php.ini. However, even after trying both the ts and nts version in WAMP, I would get:
PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.3.10/ext/imagick.dll' - The specified module could not be found.
in Unknown on line 0
But the thing is that c:/wamp/bin/php/php5.3.10/ext/imagick.dll' does exist, and yes I have checked this a lot of times.
I then downgraded ImageMagick to 6.6.2-10-Q16, but still see the same problem.
The same issue occurs on my dev machine running a nts version of PHP 5.3.10 on Apache 2.2 (all installed manually).
Looks like I could be wrong regarding the ZTS preprocessor. If I set ZTS=0 and compile, using dependency walker on the compiled dll still shows that it requires php5ts.dll which is only present on threadsafe versions of PHP.
I did more tinkering with dependency walker and found that I had to statistically link to msvc100d.dll. I then removed ZTS in the preprocessor definition and was able to compile using php5.lib instead of php5ts.dll. I think this should get me a non-ts dll.
However, when loading the extension, I am still getting:
PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) 'imagick.dll' in Unknown on line 0
And errors from dependency walker:
Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.
Error: Modules with different CPU types were found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
Installed visual c++ express 2008 and compiled using platform toolkit v90, but still facing the same issues.
Any tips appreciated :)
Solution Found! See my answer.
Got it! I hope this can help those compiling php extensions on windows in the future. What I have done is based on: https://wiki.php.net/internals/windows/stepbystepbuild
Note: I read an answer on this site that said compiling PHP extensions by itself on windows is unsupported. Based on my experiments yesterday, it seems to be a lot of work as well, so I am using the PHP build process.
The best way is to use the PHP build process.
Install Visual C++ Express 2008 (any version will do, but express is free) and Windows SDK 6.1 (note that we want the 6.1 version not anything older or newer).
Install the SVN client tools if you haven't done so and restart for your PATH variable to take effect.
Get the PHP SDK binary tools and extract it to C:\php-sdk.
Start the CMD Shell under Microsoft Windows SDK v6.1 in your start menu and run cd C:\php-sdk.
Run setenv /x86 /xp /release this creates a 32-bit release. You can use /x64 to build a 64-bit release (I have not tried this).
run bin\phpsdk_setvars.bat
run bin\phpsdk_buildtree.bat php53dev
Download the PHP source code and extract it to C:\php-sdk\php53dev\vc9\x86 so that you end up with C:\php-sdk\php53dev\vc9\x86\php5.3-xyz
Download the latest deps and extract everything to C:\php-sdk\php53dev\vc9\x86. You may be prompted to overwrite any existing folders, so press yes.
run cd C:\php-sdk\php53dev\vc9\x86
Check out the latest version of your extension from the svn repository: svn co http://svn.php.net/repository/pecl/imagick/trunk pecl/imagick I am checking out imagick here.
Install any dependencies. In my case, I need to install ImageMagick, so I downloaded the latest recommended windows binary. You will need to restart after installation to update your PATH variable, but you can do this after you have compiled. Make sure you install the C/C++ headers and includes as well.
Copy the contents of the includes directory from the ImageMagick install directory to C:\php-sdk\php53dev\vc9\x86\deps\include.
Copy the contents of the lib directory from the ImageMagick install directory to C:\php-sdk\php53dev\vc9\x86\deps\lib
Now, let's build: run cd C:\php-sdk\php53dev\vc9\x86\php5.3-xyz then buildconf then configure --help. Look at the help properly. It will show you all config flags and any avaliable extensions to enabled. In my case, since I added imagick, I had an option called --with-imagick
Run config: configure --enable-cli --with-imagick=shared --disable-zts If you want to build a non-thread-safe binary use --disable-zts, otherwise remove that configuration flag. I am not sure why, but sometimes extensions use the --with-myextension flag and sometimes --enable-myextension, so check configure --help for the flag to use. If you add =shared after the extension flag, it will be compiled as a separate DLL, which si what we want.
Compile: run nmake then nmake snap.
Done :) Check C:\php-sdk\php53dev\vc9\x86\php-5.3.10\Release (non-thread-safe) or C:\php-sdk\php53dev\vc9\x86\php-5.3.10\Release_TS (thread-safe). Your compiled binaries should be in there. The compiled extensions (pecl), should be in a ZIP file similiar to pecl-5.3.10-nts-Win32-VC9-x86.zip. Open this file and extract the extensio DLL to your ext folder in your PHP installation.
Enable the PHP extension and restart your webserver. Run phpinfo() and check that the extension is enabled.
If the extension does not work properly, make sure you reboot to update your PATH variable. In my case, I need to have the imagemagick install directory in my PATH variable.

Profit!
Is there a reason you need to compile? Why not download? It's usually much simpler/quicker on Windows.

How can I install APC on Windows? I am using PHP 5.3, Windows 7 x64.
I used
pecl install apc
I got
C:\PHP>pecl install apc
downloading APC-3.0.19.tgz ...
Starting to download APC-3.0.19.tgz (115,735 bytes) ............
done: 115,735 bytes 47 source files, building
WARNING: php_bin c:\php\php.exe appears to have a suffix \php.exe, but config
variable php_suffix does not match running: msdev APC.dsp /MAKE "APC - Release"
ERROR: Did not understand the completion status returned from msdev.exe.
Installing an extension with the pecl command means :
downloading the sources
compiling them
And, generally speaking, a windows machine doesn't have what's required to compile software like PHP and/or PHP extensions.
A better / easier solution, in your case, would probably be to find a pre-compiled .dll of the extension, that matches your system and your version of PHP.
With a bit of luck, maybe one of the versions provided on http://downloads.php.net/pierre/ could be OK ?
(It's what kind of acts as replacement of the old pecl4win, until the extensions for windows are available on windows.php.net)
For more informations about which version you should use, take a look at the Which version do I choose? section, in the left side-bar of http://windows.php.net/
It is not really important, whether you are running Windows 32-bit or 64-bit version. What matters is what Apache (webserver) version you have installed (32/64). Since lots of PHP extensions (like APC) are not available for 64-bit systems, most common setup is as follows:
Operating system 32 or 64-bit (not really important). Apache 32-bit will run easily on Windows 64-bit. The difference is, that for 32-bit apache you MUST install PHP 32-bit. Once you install 64-bit PHP, you may find difficult to install some extensions - there are almost no extensions available for 64-bit PHP platform.
therefore your webserver should be 32-bit if you care about special extensions, like APC, Imagick etc... Also you need to know if your apache is thread safe (TS) or not thread safe (NTS) and whether it has been compiled in Visual Studio 6 (VC6) or newser Visual Studio 2008 (VC9). You will easily find all this info from phpinfo() function.
as for the APC, some nice compilation for Windows are available from http://dev.freshsite.pl/php-accelerators/apc.html.
For php 5.3 you use php.net/pierre/php_apc-3.1.10-5.3-vc9-x86.zip.
Download it and copy php_apc.dll to your php ext directory. (I choose the file under ts I have thread safe php installation. There is also an apc dll file for non thread safe.)
Add extension=php_apc.dll into your php.ini file
Restart your web server
Run phpinfo() to see if it's installed or not.
I am using php 5.4 and I downloaded php.net/pierre/php_apc-3.1.10-5.4-vc9-x86.zip and its working fine.
Hope this will help mate.Good luck.
Also, make sure that the compiled version from here http://downloads.php.net/pierre/
matches your php version, otherwise the extension will not load (php v. 5.2.17 requires php_apc.dll v 5.2.17.17 - which doesn't seem to be available as of this writing - I had to downgrade the php version to play with apc).
Another point, pierre's zip packages, at least the one I downloaded, did not include the management script. you can get it from here: http://pecl.php.net/package/APC - select the version you downloaded, then navigate to Browse Source, then find your version in the 'tags' folder. the apc.php script should be there.
There's no available version for php > 5.4.
I'm using APCu instead. Just download the dll and reference it in php.ini.
This website offers updated dll and installers for Apache, PHP and APC compiled to work on windows 64 bit. I've been using it for a while and it works fine. You could an APC version compatible with PHP 5.3.22 here
I've been trying to install some PECL extensions on my laptop, but I've ran into a few problems. Whenever I run pecl install whatever from the command line I get a message saying ".\php.exe appears to have a suffix .exe, but config variable php". It seems like PECL is using PEAR to perform installations. I checked and php_suffix is located in the files PEAR_Config.php and PEAR_Builder.php, but I'm not sure what to do with it in there.
Any ideas on how to fix this or workarounds? Unfortunately the pecl4win seems to be down, and http://downloads.php.net/pierre/ the site I usually go to for the .dll's has outdated versions for the version of PHP I'm using (5.3.1).
Unfortunately I don't know the specifics, but at least I can point you in the right direction To use pecl on windows, you need to setup Visual Studio c/c++ or MingW32 c/c++ and then configure pecl to use either compiler for building the requested extensions.
Unlike pear packages, pecl packages are PHP c extensions that needed to be compiled against your local PHP install.
Update
https://wiki.php.net/internals/windows/stepbystepbuild A mostly friendly wiki page on setting up a windows box for building PHP from source. Looks like you need to build the interpreter and support libraries before you can get pecl working.
