763 %prompt perlcc a.p -L ../lib a.c
764 # Compiles with the perl libraries
765 # inside ../lib included.
769 'perlcc' is the frontend into the perl compiler. Typing 'perlcc a.p'
770 compiles the code inside a.p into a standalone executable, and
771 perlcc A.pm will compile into a shared object, A.so, suitable for inclusion
772 into a perl program via "use A".
774 There are quite a few flags to perlcc which help with such issues as compiling
775 programs in bulk, testing compiled programs for compatibility with the
776 interpreter, and controlling.
782 =item -L < library_directories >
784 Adds directories in B<library_directories> to the compilation command.
786 =item -I < include_directories >
788 Adds directories inside B<include_directories> to the compilation command.
790 =item -C < c_code_name >
792 Explicitly gives the name B<c_code_name> to the generated c code which is to
793 be compiled. Can only be used if compiling one file on the command line.
795 =item -o < executable_name >
797 Explicitly gives the name B<executable_name> to the executable which is to be
798 compiled. Can only be used if compiling one file on the command line.
800 =item -e < perl_line_to_execute>
802 Compiles 'one liners', in the same way that B<perl -e> runs text strings at
803 the command line. Default is to have the 'one liner' be compiled, and run all
804 in one go (see B<-run>); giving the B<-o> flag saves the resultant executable,
805 rather than throwing it away. Use '-argv' to pass arguments to the executable
808 =item -regex <rename_regex>
810 Gives a rule B<rename_regex> - which is a legal perl regular expression - to
811 create executable file names.
813 =item -verbose <verbose_level>
815 Show exactly what steps perlcc is taking to compile your code. You can change
816 the verbosity level B<verbose_level> much in the same way that the '-D' switch
817 changes perl's debugging level, by giving either a number which is the sum of
818 bits you want or a list of letters representing what you wish to see. Here are
819 the verbosity levels so far :
821 Bit 1(g): Code Generation Errors to STDERR
822 Bit 2(a): Compilation Errors to STDERR
823 Bit 4(t): Descriptive text to STDERR
824 Bit 8(f): Code Generation Errors to file (B<-log> flag needed)
825 Bit 16(c): Compilation Errors to file (B<-log> flag needed)
826 Bit 32(d): Descriptive text to file (B<-log> flag needed)
828 If the B<-log> tag is given, the default verbose level is 63 (ie: mirroring
829 all of perlcc's output to both the screen and to a log file). If no B<-log>
830 tag is given, then the default verbose level is 7 (ie: outputting all of
831 perlcc's output to STDERR).
833 NOTE: Because of buffering concerns, you CANNOT shadow the output of '-run' to
834 both a file, and to the screen! Suggestions are welcome on how to overcome this
835 difficulty, but for now it simply does not work properly, and hence will only go
840 Opens, for append, a logfile to save some or all of the text for a given
841 compile command. No rewrite version is available, so this needs to be done
844 =item -argv <arguments>
846 In combination with '-run' or '-e', tells perlcc to run the resulting
847 executable with the string B<arguments> as @ARGV.
851 Tells perl to save the intermediate C code. Usually, this C code is the name
852 of the perl code, plus '.c'; 'perlcode.p' gets generated in 'perlcode.p.c',
853 for example. If used with the '-e' operator, you need to tell perlcc where to
854 save resulting executables.
858 Tells perlcc to only create the intermediate C code, and not compile the
859 results. Does an implicit B<-sav>, saving the C code rather than deleting it.
863 Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE
864 B<-run> FLAG TO B<perlcc>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS
865 ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING.
869 Indicate that the programs at the command line are programs, and should be
870 compiled as such. B<perlcc> will automatically determine files to be
871 programs if they have B<.p>, B<.pl>, B<.bat> extensions.
875 Indicate that the programs at the command line are modules, and should be
876 compiled as such. B<perlcc> will automatically determine files to be
877 modules if they have the extension B<.pm>.
883 Most of the work of B<perlcc> is done at the command line. However, you can
884 change the heuristic which determines what is a module and what is a program.
885 As indicated above, B<perlcc> assumes that the extensions:
889 indicate a perl program, and:
893 indicate a library, for the purposes of creating executables. And furthermore,
894 by default, these extensions will be replaced (and dropped ) in the process of
895 creating an executable.
897 To change the extensions which are programs, and which are modules, set the
898 environmental variables:
903 These two environmental variables take colon-separated, legal perl regular
904 expressions, and are used by perlcc to decide which objects are which.
907 setenv PERL_SCRIPT_EXT '.prl$:.perl$'
908 prompt% perlcc sample.perl
910 will compile the script 'sample.perl' into the executable 'sample', and
912 setenv PERL_MODULE_EXT '.perlmod$:.perlmodule$'
914 prompt% perlcc sample.perlmod
916 will compile the module 'sample.perlmod' into the shared object
919 NOTE: the '.' in the regular expressions for PERL_SCRIPT_EXT and PERL_MODULE_EXT
920 is a literal '.', and not a wild-card. To get a true wild-card, you need to
921 backslash the '.'; as in:
923 setenv PERL_SCRIPT_EXT '\.\.\.\.\.'
925 which would have the effect of compiling ANYTHING (except what is in
926 PERL_MODULE_EXT) into an executable with 5 less characters in its name.
930 'perlcc' uses a temporary file when you use the B<-e> option to evaluate
931 text and compile it. This temporary file is 'perlc$$.p'. The temporary C code is
932 perlc$$.p.c, and the temporary executable is perlc$$.
934 When you use '-run' and don't save your executable, the temporary executable is
939 perlcc currently cannot compile shared objects on Win32. This should be fixed
