Compiling igbinary from source on Windows

This guide is added for packagers or developers of the igbinary project.

Downloading prebuilt DLLs from PECL is easier for end users.

Setting up a Windows VM

If you don't have Windows installed:

  1. Download a VM from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/ (E.g. Windows 7 IE11) Prefer Windows 7. The trial period can be extended.
  2. Install the VM. Keep the disk image around, the VM trial period expires in 30 days.
  3. (Optional) Configure the VM to use more than one core (but not all available cores) to speed up installation/upgrading/compiling.
  4. Download https://support.microsoft.com/en-us/kb/3102810#bookmark-prerequisite (x86), disable internet, install that patch, re-enable internet)
  5. Run Windows Updates, which will take a long time.
  6. Read the instructions on the desktop background (for extending trial period).
  7. (Windows 7)Search for "Command Prompt", right click on it and click "Run as administrator", and execute slmgr /ato to extend the trial period to 90 days.

If the license expires/is about to expire, it is possible to "re-arm" (extend) the license several times with slmgr

Installing Visual Studio

  1. Download the version of Visual Studio needed to build the desired version of PHP (mentioned on https://wiki.php.net/internals/windows/stepbystepbuild#building_pecl_extensions for PHP 7.0-7.1), and https://wiki.php.net/internals/windows/stepbystepbuild_sdk_2 for PHP 7.2+

    At the time of writing, that was Visual Studio Community Edition 2015 for PHP7.0 - 7.2, and Visual Studio Community Edition 2017 for PHP 7.2+

  2. Install Visual Studio 2015. (Use custom installation, make sure that all C++ features are enabled)

Downloading PHP

See https://wiki.php.net/internals/windows/stepbystepbuild

Prefer downloading stable releases of php?

(This hasn't been tested yet on the suggested VM)

Building igbinary

See https://wiki.php.net/internals/windows/stepbystepbuild#building\_pecl\_extensions

Install APCu (optional)

Note: The Windows build hasn't worked for a while in 5.6, so there may be compilation errors or test failures.

TODO: Make sure that config.w32 works without APCu installed.

  1. Open the extension's page on PECL (APCu)

  2. Download the extension source either by:

    • downloading a source archive
    • fetching the source from the extension's repository (link can be found under Browse Source)

  3. Create a directory named pecl on the same level as your PHP source directory, e.g. C:\php-sdk\phpdev\vc11\x86\pecl

  4. Extract or clone the extension source code to the pecl directory

    • if cloning, clone to a subdirectory, e.g. C:\php-sdk\phpdev\vc11\x86\pecl\apcu
    • source code archive should already contain a subdirectory named e.g. apcu-4.0.7

  5. Open a command prompt, run the setvars script, and enter your PHP source directory

  6. Rebuild the configure script by running:

    buildconf

  7. Executing configure --help should now contain an option to enable APCu

    --enable-apcu    Whether to enable APCu support

  8. Configure and build:

    configure --disable-all --enable-cli --enable-apcu

    nmake

  9. Test the binary with a php -m command, to make sure APCu is loaded

Install igbinary

Similar to the above instructions.

  1. (This isn't released yet, skip this step and download from github) Open the extension's page on PECL ( APCu)

  2. Download the extension source either by:

  3. If it doesn't already exist, then create a directory named pecl on the same level as your PHP source directory, e.g. C:\php-sdk\phpdev\vc11\x86\pecl

  4. Extract or clone the extension source code to the pecl directory

    • if cloning, clone to a subdirectory, e.g. C:\php-sdk\phpdev\vc11\x86\pecl\igbinary
    • source code archive should already contain a subdirectory with a name like igbinary-2.0.8. That should be renamed to igbinary.

  5. Open a command prompt, run the setvars script, and enter your PHP source directory (not the extension directory)

  6. Rebuild the configure script by running:

    buildconf

  7. Executing configure --help should now contain options. (config.m4 currently has no options. May allow disabling apcu support in the future, etc.)

    --enable-apcu    Whether to enable APCu support
--enable-igbinary Whether to enable igbinary support

  8. Configure and build: One may want to set CFLAGS (or equivalent) to -O2 so it will be faster?

    If you want to test sessions and apcu as well, an extremely minimal configure script would be:

    configure --disable-all --enable-cli --enable-cgi --enable-apcu --enable-igbinary --enable-json

    (If testing a full installation, add --enable-igbinary to the config flags you were already using)

    Then, build/rebuild php.

    nmake

  9. Invoke the php -m command to confirm that igbinary is loaded. (and any other extensions such as APCu)

  10. Run the unit tests. Most should pass, some should be skipped (Or be expected failures(XFAIL)), none should fail.

    # In the php source directory, execute the following commands:
nmake test TESTS=C:\php-sdk\phpdev\path\to\igbinary\tests
# Optional test of related extensions:
# nmake test TESTS=C:\php-sdk\phpdev\path\to\apcu\tests

    In recent releases of php7, this can be probably done by running nmake test within the igbinary folder immediately after configuration for the desired php7 version.
