Install bcompiler for PHP on Ubuntu Linux

By admin | August 10, 2008

The PHP bytecode compiler is a useful way to convert PHP to bytecode, which can then be converted to binaries. However, the Ubuntu packaging team has not yet made a binary package of bcompiler available. However, you can install this bytecode compiler yourself with these 9 easy to follow steps. A binary build is availible, but you should try to compile/install it yourself because the binary extension might not be suitable for your computer.

  1. Install the basic dependencies with sudo apt-get install automake m4 php5-dev

    Libraries have been installed in:
    /var/tmp/pear-build-root/bcompiler-0.8/modules

    If you ever happen to want to link against installed libraries
    in a given directory, LIBDIR, you must either use libtool, and
    specify the full pathname of the library, or use the `-LLIBDIR’
    flag during linking and do at least one of the following:
    – add LIBDIR to the `LD_LIBRARY_PATH’ environment variable
    during execution
    – add LIBDIR to the `LD_RUN_PATH’ environment variable
    during linking
    – use the `-Wl,–rpath -Wl,LIBDIR’ linker flag
    – have your system administrator add LIBDIR to `/etc/ld.so.conf’

    See any operating system documentation about shared libraries for
    more information, such as the ld(1) and ld.so(8) manual pages.

    Build complete.
    Don’t forget to run ‘make test’.

    Build process completed successfully
    Installing ‘/usr/lib/php5/20060613+lfs/bcompiler.so’
    install ok: channel://pear.php.net/bcompiler-0.8

  4. If you encounter “ERROR: `phpize’ failed“, that means you have not yet installed php5-dev. Repeat step 1 then try again.
  5. If you encounter “configure: WARNING: You will need re2c 0.12.0 or later if you want to regenerate PHP parsers“, repeat step 2 to install re2c.
  6. If you encounter “checking for BZip2 in default path… not found” or “configure: error: Please reinstall the BZip2 distribution“, repeat step 2 to install libbz2-dev.
  7. Add “extension=bcompiler.so” to /etc/php5/cli/php.ini to activate the extension.
  8. You’re done! To test it, save the following file as example.php: 
    <?php
/**
* A function to output hello world
*
* @function helloWorld
* @return void
*/
function helloWorld() {
echo "Hello World!\n";
}
?>

    Save the following as compile.php:

    <?php
$fh = fopen("example.phb", "w");
bcompiler_write_header($fh);
bcompiler_write_file($fh, "example.php");
bcompiler_write_footer($fh);
fclose($fh);
?>

    And save this one as use_p.php:

    <?php
include_once('example.phb');
helloWorld();
helloWorld();
helloWorld();
?>

    Now run compile.php to compile it. Then run use_p.php – you should see “Hello World!” three times. If you do, you’re done!

  9. If for any reason your computer cannot compile bcompiler.so, here is a binary build just in case. Do not forget to test it using the step above!
