824 | |
825 | =head1 DESCRIPTION |
826 | |
827 | 'perlcc' is the frontend into the perl compiler. Typing 'perlcc a.p' |
828 | compiles the code inside a.p into a standalone executable, and |
829 | perlcc A.pm will compile into a shared object, A.so, suitable for inclusion |
830 | into a perl program via "use A". |
831 | |
832 | There are quite a few flags to perlcc which help with such issues as compiling |
833 | programs in bulk, testing compiled programs for compatibility with the |
834 | interpreter, and controlling. |
835 | |
836 | =head1 OPTIONS |
837 | |
838 | =over 4 |
839 | |
840 | =item -L < library_directories > |
841 | |
842 | Adds directories in B<library_directories> to the compilation command. |
843 | |
844 | =item -I < include_directories > |
845 | |
846 | Adds directories inside B<include_directories> to the compilation command. |
847 | |
848 | =item -C < c_code_name > |
849 | |
850 | Explicitly gives the name B<c_code_name> to the generated c code which is to |
851 | be compiled. Can only be used if compiling one file on the command line. |
852 | |
853 | =item -o < executable_name > |
854 | |
855 | Explicitly gives the name B<executable_name> to the executable which is to be |
856 | compiled. Can only be used if compiling one file on the command line. |
857 | |
858 | =item -e < perl_line_to_execute> |
859 | |
860 | Compiles 'one liners', in the same way that B<perl -e> runs text strings at |
861 | the command line. Default is to have the 'one liner' be compiled, and run all |
862 | in one go (see B<-run>); giving the B<-o> flag saves the resultant executable, |
863 | rather than throwing it away. Use '-argv' to pass arguments to the executable |
864 | created. |
865 | |
866 | =item -regex <rename_regex> |
867 | |
868 | Gives a rule B<rename_regex> - which is a legal perl regular expression - to |
869 | create executable file names. |
870 | |
871 | =item -verbose <verbose_level> |
872 | |
873 | Show exactly what steps perlcc is taking to compile your code. You can change |
874 | the verbosity level B<verbose_level> much in the same way that the '-D' switch |
875 | changes perl's debugging level, by giving either a number which is the sum of |
876 | bits you want or a list of letters representing what you wish to see. Here are |
877 | the verbosity levels so far : |
878 | |
879 | Bit 1(g): Code Generation Errors to STDERR |
880 | Bit 2(a): Compilation Errors to STDERR |
881 | Bit 4(t): Descriptive text to STDERR |
882 | Bit 8(f): Code Generation Errors to file (B<-log> flag needed) |
883 | Bit 16(c): Compilation Errors to file (B<-log> flag needed) |
884 | Bit 32(d): Descriptive text to file (B<-log> flag needed) |
885 | |
886 | If the B<-log> tag is given, the default verbose level is 63 (ie: mirroring |
887 | all of perlcc's output to both the screen and to a log file). If no B<-log> |
888 | tag is given, then the default verbose level is 7 (ie: outputting all of |
889 | perlcc's output to STDERR). |
890 | |
891 | NOTE: Because of buffering concerns, you CANNOT shadow the output of '-run' to |
892 | both a file, and to the screen! Suggestions are welcome on how to overcome this |
893 | difficulty, but for now it simply does not work properly, and hence will only go |
894 | to the screen. |
895 | |
896 | =item -log <logname> |
897 | |
898 | Opens, for append, a logfile to save some or all of the text for a given |
899 | compile command. No rewrite version is available, so this needs to be done |
900 | manually. |
901 | |
902 | =item -argv <arguments> |
903 | |
904 | In combination with '-run' or '-e', tells perlcc to run the resulting |
905 | executable with the string B<arguments> as @ARGV. |
906 | |
907 | =item -sav |
908 | |
909 | Tells perl to save the intermediate C code. Usually, this C code is the name |
910 | of the perl code, plus '.c'; 'perlcode.p' gets generated in 'perlcode.p.c', |
911 | for example. If used with the '-e' operator, you need to tell perlcc where to |
912 | save resulting executables. |
913 | |
914 | =item -gen |
915 | |
916 | Tells perlcc to only create the intermediate C code, and not compile the |
917 | results. Does an implicit B<-sav>, saving the C code rather than deleting it. |
918 | |
919 | =item -run |
920 | |
921 | Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE |
922 | B<-run> FLAG TO B<perlcc>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS |
923 | ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING. |
924 | |
925 | =item -prog |
926 | |
927 | Indicate that the programs at the command line are programs, and should be |
928 | compiled as such. B<perlcc> will automatically determine files to be |
929 | programs if they have B<.p>, B<.pl>, B<.bat> extensions. |
930 | |
931 | =item -mod |
932 | |
933 | Indicate that the programs at the command line are modules, and should be |
934 | compiled as such. B<perlcc> will automatically determine files to be |
935 | modules if they have the extension B<.pm>. |
936 | |
937 | =back |
938 | |
939 | =head1 ENVIRONMENT |
940 | |
941 | Most of the work of B<perlcc> is done at the command line. However, you can |
942 | change the heuristic which determines what is a module and what is a program. |
943 | As indicated above, B<perlcc> assumes that the extensions: |
944 | |
945 | .p$, .pl$, and .bat$ |
946 | |
947 | indicate a perl program, and: |
948 | |
949 | .pm$ |
950 | |
951 | indicate a library, for the purposes of creating executables. And furthermore, |
ef712cf7 |
952 | by default, these extensions will be replaced (and dropped) in the process of |
52cebf5e |
953 | creating an executable. |
954 | |
955 | To change the extensions which are programs, and which are modules, set the |
956 | environmental variables: |
957 | |
958 | PERL_SCRIPT_EXT |
959 | PERL_MODULE_EXT |
960 | |
961 | These two environmental variables take colon-separated, legal perl regular |
962 | expressions, and are used by perlcc to decide which objects are which. |
963 | For example: |
964 | |
965 | setenv PERL_SCRIPT_EXT '.prl$:.perl$' |
966 | prompt% perlcc sample.perl |
967 | |
968 | will compile the script 'sample.perl' into the executable 'sample', and |
969 | |
970 | setenv PERL_MODULE_EXT '.perlmod$:.perlmodule$' |
971 | |
972 | prompt% perlcc sample.perlmod |
973 | |
974 | will compile the module 'sample.perlmod' into the shared object |
975 | 'sample.so' |
976 | |
977 | NOTE: the '.' in the regular expressions for PERL_SCRIPT_EXT and PERL_MODULE_EXT |
978 | is a literal '.', and not a wild-card. To get a true wild-card, you need to |
979 | backslash the '.'; as in: |
980 | |
981 | setenv PERL_SCRIPT_EXT '\.\.\.\.\.' |
982 | |
983 | which would have the effect of compiling ANYTHING (except what is in |
984 | PERL_MODULE_EXT) into an executable with 5 less characters in its name. |
985 | |
986 | =head1 FILES |
987 | |
988 | 'perlcc' uses a temporary file when you use the B<-e> option to evaluate |
989 | text and compile it. This temporary file is 'perlc$$.p'. The temporary C code is |
990 | perlc$$.p.c, and the temporary executable is perlc$$. |
991 | |
992 | When you use '-run' and don't save your executable, the temporary executable is |
993 | perlc$$ |
994 | |
995 | =head1 BUGS |
996 | |
997 | perlcc currently cannot compile shared objects on Win32. This should be fixed |
998 | by perl5.005. |
