Hiding perl-cgi code
Hi all,
This is my first post in this forum. Searched the threads, couldn't get information about this.
I have developed a web-based tool using CGI. The code consists of cgi files (.cgi) and functions written as Perl Modules( .pm files). As it is the tool works perfect.
Now is there any way, I can hide this code? Something like making these scripts as executables?
I have tried the following:
> 'perlcc' utility: It takes a lot of memory in creating an executable file of each script. Moreover, they mention that it is 'VERY' experimental and is still under development.
> 'perlcc' also generates a 'bytecode' for the scripts. This bytecode would require only the perl interpretor and a ByteLoader module. But, this bytecode generator doesn't support for bytecodes of perl modules.
Is there any other way I can achieve the hiding of my code?
Rgds,
Sudhir.

PERLCC(1) Perl Programmers Reference Guide PERLCC(1)
NAME
perlcc - generate executables from Perl programs
SYNOPSIS
$ perlcc hello # Compiles into executable 'a.out'
$ perlcc -o hello hello.pl # Compiles into executable 'hello'
$ perlcc -O file # Compiles using the optimised C backend
$ perlcc -B file # Compiles using the bytecode backend
$ perlcc -c file # Creates a C file, 'file.c'
$ perlcc -S -o hello file # Creates a C file, 'file.c',
# then compiles it to executable 'hello'
$ perlcc -c out.c file # Creates a C file, 'out.c' from 'file'
$ perlcc -e 'print q//' # Compiles a one-liner into 'a.out'
$ perlcc -c -e 'print q//' # Creates a C file 'a.out.c'
$ perlcc -I /foo hello # extra headers (notice the space after -I)
$ perlcc -L /foo hello # extra libraries (notice the space after -L)
$ perlcc -r hello # compiles 'hello' into 'a.out', runs 'a.out'.
$ perlcc -r hello a b c # compiles 'hello' into 'a.out', runs 'a.out'.
# with arguments 'a b c'
$ perlcc hello -log c # compiles 'hello' into 'a.out' logs compile
# log into 'c'.
DESCRIPTION
perlcc creates standalone executables from Perl programs, using the code generators provided by the B module. At present, you may either
create executable Perl bytecode, using the "-B" option, or generate and compile C files using the standard and 'optimised' C backends.
The code generated in this way is not guaranteed to work. The whole codegen suite ("perlcc" included) should be considered very experimen-
tal. Use for production purposes is strongly discouraged.
OPTIONS
-Llibrary directories
Adds the given directories to the library search path when C code is passed to your C compiler.
-Iinclude directories
Adds the given directories to the include file search path when C code is passed to your C compiler; when using the Perl bytecode
option, adds the given directories to Perl's include path.
-o output file name
Specifies the file name for the final compiled executable.
-c C file name
Create C code only; do not compile to a standalone binary.
-e perl code
Compile a one-liner, much the same as "perl -e '...'"
-S Do not delete generated C code after compilation.
-B Use the Perl bytecode code generator.
-O Use the 'optimised' C code generator. This is more experimental than everything else put together, and the code created is not guaran-
teed to compile in finite time and memory, or indeed, at all.
-v Increase verbosity of output; can be repeated for more verbose output.
-r Run the resulting compiled script after compiling it.
-log
Log the output of compiling to a file rather than to stdout.
