NAME
perlcc - generate executables from Perl programs

SYNOPSIS
perlcc hello.pl # Compiles into executable 'a.out'
perlcc -o hello hello.pl # Compiles into executable 'hello'

perlcc -O file.pl # Compiles using the optimised CC backend
perlcc -O3 file.pl # Compiles with C, using -O3 optimizations
perlcc -B file.pl # Compiles using the bytecode backend
perlcc -B -m file.pm # Compiles a module to file.pmc

perlcc -c file.pl # Creates a C file, 'file.c'
perlcc -S -o hello file.pl # Keep C file
perlcc -c out.c file.pl # Creates a C file, 'out.c' from 'file'
perlcc --staticxs -r -o hello hello.pl # Compiles,links and runs with
# XS modules static/dynaloaded

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 for C
perlcc -L /foo hello # extra libraries for C
perlcc --Wb=-Dsp # extra perl compiler options
perlcc -fno-delete-pkg # extra perl compiler options
perlcc --Wc=-fno-openmp # extra C compiler options
perlcc --Wl=-s # extra C linker options

perlcc -uIO::Socket # force saving IO::Socket
perlcc -UB # "unuse" B, compile without any B symbols

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.log # compiles 'hello' into 'a.out', log into 'c.log'

perlcc -h # help, only SYNOPSIS
perlcc -v2 -h # verbose help, also DESCRIPTION and OPTIONS
perlcc --version # prints internal perlcc and the B-C release version

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
-LC library directories
Adds the given directories to the library search path when C code
is passed to your C compiler.

-IC include 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.

Without given output file name we use the base of the input file,
or with "-e" a.out resp. a.exe and a randomized intermediate C
filename. If the input file is an absolute path on a non-windows
system use the basename.

-c C file name
Create C file only; do not compile and link to a standalone binary.

-e perl code
Compile a one-liner, much the same as "perl -e '...'"

--check
Pass -c flag to the backend, prints all backend warnings to STDOUT
and exits before generating and compiling code. Similar to perl -c.

-S "Keep source". Do not delete generated C code after compilation.

-B Use the Perl bytecode code generator.

-O Use the 'optimised' C code generator B::CC. 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.

-O1-4
Pass the numeric optimisation option to the compiler backend.
Shortcut for "-Wb=-On".

This does not enforce B::CC.

-v 0-6
Set verbosity of output from 0 to max. 6.

-r Run the resulting compiled script after compiling it.

--log logfile
Log the output of compiling to a file rather than to stdout.

-f<option> or --f=<option>
Pass the options to the compiler backend, such as "-fstash" or
"-fno-delete-pkg".

--Wb=options
Pass the options to the compiler backend, such as "--Wb=-O2,-v"

--Wc=options
Pass comma-seperated options to cc.

--Wl=options
Pass comma-seperated options to ld.

-T or -t
run the backend using perl -T or -t

-A Allow perl options to be passed to the executable first, like -D...

Adds "-DALLOW_PERL_OPTIONS" which omits "--" from being added to
the options handler.

-u package
Add package(s) to compiler and force linking to it.

-U package
Skip package(s). Do not compile and link the package and its sole
dependencies.

--stash
Detect external packages automatically via B::Stash

--static
Link to static libperl.a

--staticxs
Link to static XS if available. If the XS libs are only available
as shared libs link to those ("prelink").

Systems without rpath (windows, cygwin) must be extend
LD_LIBRARY_PATH/PATH at run-time. Together with -static, purely
static modules and no run-time eval or require this will gain no
external dependencies.

--shared
Link to shared libperl

--sharedxs
Link shared XSUBs if the linker supports it. No DynaLoader needed.
This will still require the shared XSUB libraries to be installed
at the client, modification of @INC in the source is probably
required. (Not yet implemented)

-m|--sharedlib [Modulename]
Create a module, resp. a shared library. Currently only enabled
for Bytecode and CC. (not yet tested)

--testsuite
Tries be nice to Test:: modules, like preallocating the file
handles 4 and 5, and munge the output of BEGIN.

perlcc -r --testsuite t/harness

--time
Benchmark the different phases c (B::* compilation), cc (cc compile
+ link), and r (runtime).

--no-spawn
Do not spawn subprocesses for compilation, because broken shells
might not be able to kill its children.
