generate executables from Perl programs

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 experimental. 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 guaranteed 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.
