Install BCOMPILER for PHP5 on Ubuntu Lucid

At some point maybe we are faced to protect our work from people who want to imitate our artificial program. There is a trick to randomize results of our work especially the PHP is by using bcompiler. Bcompiler dedicated for eschool program, where i used for first time at my ubuntu server.

In this case we use the latest Ubuntu Lucid Lynx 10.04 or Dewalinux
1. Install the basic dependencies with :
root@yoyok-desktop:/# apt-get install automake m4 php5-dev php5-pear

2. then install next dependencies
root@yoyok-desktop:/# apt-get install libbz2-dev

----------------------------------------------------------------------
Libraries have been installed in:
/var/tmp/pear-build-root/bcompiler-0.9.1/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'.

4. If you encounter “ERROR: `phpize’ failed“, that means you have not yet installed php5-dev. Repeat step 1 then try again

5. Add “extension=bcompiler.so” to /etc/php5/cli/php.ini and /etc/php5/apache2/php.ini to activate the extension.
6. wget http://bencoder.urdada.net/bencoder
7. chmod 755 bencoder
8. cp bencoder /usr/local/bin/
9. Usage bcompiler :
bencoder [-f] [-q] [-t] -o FILE file1.php
bencoder [-f] [-q] [-t] -o OUTDIR file1.php file2.php ...
bencoder [-f] [-q] [-t] -o OUTDIR -s SRCDIR [-e SUFFIX] [-r] [-c] [-l]

-o FILE : the file name to write the encoded script
(default to '-encoded.XXX' suffix)
-o OUTDIR : the directory to write all encoded files

-a SRCDIR
-s SRCDIR : encode all files in this source directory

-r : encode directories recursively (no by default)
-f : force overwriting even if the target exists
-t : truncate/keep only the basename of the file into the bytecode
-e SUFFIX : encode the files with the SUFFIX extension only (default: php)
(regular expression allowed, ex: "php|inc")
-c : copy files those shouldn't be encoded (no by default)
-l : follow symbolic link (no by default)
-q : do not print the file name while encoding or copying
-b
-bz2 : compress the encoded files with bz2 (needs bzip2-extension)

By using this bcompiler, the program could be the result of our work is protected and not easily imitated.
Good luck
