| 570 |
|
|---|
| 571 | $ perlcc hello # Compiles into executable 'a.out'
|
|---|
| 572 | $ perlcc -o hello hello.pl # Compiles into executable 'hello'
|

| 573 |
|
|---|
| 574 | $ perlcc -O file # Compiles using the optimised C backend
|
|---|
| 575 | $ perlcc -B file # Compiles using the bytecode backend
|
|---|
| 576 |
|
|---|
| 577 | $ perlcc -c file # Creates a C file, 'file.c'
|
|---|
| 578 | $ perlcc -S -o hello file # Creates a C file, 'file.c',
|
|---|
| 579 | # then compiles it to executable 'hello'
|
|---|
| 580 | $ perlcc -c out.c file # Creates a C file, 'out.c' from 'file'
|
|---|
| 581 |
|
|---|
| 582 | $ perlcc -e 'print q//' # Compiles a one-liner into 'a.out'
|
|---|
| 583 | $ perlcc -c -e 'print q//' # Creates a C file 'a.out.c'
|

| 584 |
|
|---|
| 585 | $ perlcc -I /foo hello # extra headers (notice the space after -I)

| 595 | =head1 DESCRIPTION
|
|---|
| 596 |
|
|---|
| 597 | F<perlcc> creates standalone executables from Perl programs, using the
|
|---|
| 598 | code generators provided by the L<B> module. At present, you may
|
|---|
| 599 | either create executable Perl bytecode, using the C<-B> option, or
|
|---|
| 600 | generate and compile C files using the standard and 'optimised' C
|
|---|
| 601 | backends.
|
|---|
| 602 |
|
|---|
| 603 | The code generated in this way is not guaranteed to work. The whole
|
|---|
| 604 | codegen suite (C<perlcc> included) should be considered B<very>
|
|---|
| 605 | experimental. Use for production purposes is strongly discouraged.
|
|---|
| 606 |
|
|---|
| 607 | =head1 OPTIONS
|
|---|
| 608 |
|
|---|
| 609 | =over 4
|
|---|
| 610 |
|
|---|
| 611 | =item -LI<library directories>
|
|---|
| 612 |
|
|---|
| 613 | Adds the given directories to the library search path when C code is
|
|---|
| 614 | passed to your C compiler.
|
|---|
| 615 |
|
|---|
| 616 | =item -II<include directories>
|
|---|
| 617 |
|
|---|
| 618 | Adds the given directories to the include file search path when C code is
|
|---|
| 619 | passed to your C compiler; when using the Perl bytecode option, adds the
|
|---|
| 620 | given directories to Perl's include path.
|
|---|
| 621 |
|
|---|
| 622 | =item -o I<output file name>
|
|---|
| 623 |
|
|---|
| 624 | Specifies the file name for the final compiled executable.
|
|---|
| 625 |
|
|---|
| 626 | =item -c I<C file name>
|
|---|
| 627 |
|
|---|
| 628 | Create C code only; do not compile to a standalone binary.
|
|---|
| 629 |
|
|---|
| 630 | =item -e I<perl code>
|
|---|
| 631 |
|
|---|
| 632 | Compile a one-liner, much the same as C<perl -e '...'>
|
|---|
| 633 |
|
|---|
| 634 | =item -S
|
|---|
| 635 |
|
|---|
| 636 | Do not delete generated C code after compilation.
|
|---|
| 637 |
|
|---|
| 638 | =item -B
|
|---|
| 639 |
|
|---|
| 640 | Use the Perl bytecode code generator.
|
|---|
| 641 |
|
|---|
| 642 | =item -O
|
|---|
| 643 |
|
|---|
| 644 | Use the 'optimised' C code generator. This is more experimental than
|
|---|
| 645 | everything else put together, and the code created is not guaranteed to
|
|---|
| 646 | compile in finite time and memory, or indeed, at all.
|
|---|
| 647 |
|
|---|
| 648 | =item -v
|
|---|
| 649 |
|
|---|
| 650 | Increase verbosity of output; can be repeated for more verbose output.
|
|---|
| 651 |
|
|---|
| 652 | =item -r
|
|---|
| 653 |
|
|---|
| 654 | Run the resulting compiled script after compiling it.
|
|---|
| 655 |
|
|---|
| 656 | =item -log
|
|---|
| 657 |
|
|---|
| 658 | Log the output of compiling to a file rather than to stdout.
|
|---|
