perlcc − generate executables from Perl programs
$ 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’.
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.
−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.
