883 | # Compiles with the perl libraries | |
884 | # inside ../lib included. | |
885 | ||
886 | =head1 DESCRIPTION | |
887 | ||
888 | 'perlcc' is the frontend into the perl compiler. Typing 'perlcc a.p' | |
889 | compiles the code inside a.p into a standalone executable, and | |
890 | perlcc A.pm will compile into a shared object, A.so, suitable for inclusion | |
891 | into a perl program via "use A". | |
892 | ||
893 | There are quite a few flags to perlcc which help with such issues as compiling | |
894 | programs in bulk, testing compiled programs for compatibility with the | |
895 | interpreter, and controlling. | |
896 | ||
897 | =head1 OPTIONS | |
898 | ||
899 | =over 4 | |
900 | ||
901 | =item -L < library_directories > | |
902 | ||
903 | Adds directories in B<library_directories> to the compilation command. | |
904 | ||
905 | =item -I < include_directories > | |
906 | ||
907 | Adds directories inside B<include_directories> to the compilation command. | |
908 | ||
909 | =item -C < c_code_name > | |
910 | ||
9636a016 GS |
911 | Explicitly gives the name B<c_code_name> to the generated file containing |
912 | the C code which is to be compiled. Can only be used if compiling one file | |
913 | on the command line. | |
52cebf5e EP |
914 | |
915 | =item -o < executable_name > | |
916 | ||
917 | Explicitly gives the name B<executable_name> to the executable which is to be | |
918 | compiled. Can only be used if compiling one file on the command line. | |
919 | ||
920 | =item -e < perl_line_to_execute> | |
921 | ||
922 | Compiles 'one liners', in the same way that B<perl -e> runs text strings at | |
923 | the command line. Default is to have the 'one liner' be compiled, and run all | |
924 | in one go (see B<-run>); giving the B<-o> flag saves the resultant executable, | |
925 | rather than throwing it away. Use '-argv' to pass arguments to the executable | |
926 | created. | |
927 | ||
9636a016 GS |
928 | =item -b |
929 | ||
930 | Generates bytecode instead of C code. | |
931 | ||
932 | =item -opt | |
933 | ||
934 | Uses the optimized C backend (C<B::CC>)rather than the simple C backend | |
935 | (C<B::C>). Beware that the optimized C backend creates very large | |
936 | switch structures and structure initializations. Many C compilers | |
937 | find it a challenge to compile the resulting output in finite amounts | |
938 | of time. Many Perl features such as C<goto LABEL> are also not | |
939 | supported by the optimized C backend. The simple C backend should | |
940 | work in more instances, but can only offer modest speed increases. | |

942 | =item -regex <rename_regex> |
943 | ||
944 | Gives a rule B<rename_regex> - which is a legal perl regular expression - to | |
945 | create executable file names. | |
946 | ||
947 | =item -verbose <verbose_level> | |
948 | ||

949 | Show exactly what steps perlcc is taking to compile your code. You can |
950 | change the verbosity level B<verbose_level> much in the same way that | |
951 | the C<-D> switch changes perl's debugging level, by giving either a | |
952 | number which is the sum of bits you want or a list of letters | |
953 | representing what you wish to see. Here are the verbosity levels so | |
954 | far : | |
52cebf5e EP |
955 | |
956 | Bit 1(g): Code Generation Errors to STDERR | |
957 | Bit 2(a): Compilation Errors to STDERR | |
958 | Bit 4(t): Descriptive text to STDERR | |
959 | Bit 8(f): Code Generation Errors to file (B<-log> flag needed) | |
960 | Bit 16(c): Compilation Errors to file (B<-log> flag needed) | |
961 | Bit 32(d): Descriptive text to file (B<-log> flag needed) | |
962 | ||
963 | If the B<-log> tag is given, the default verbose level is 63 (ie: mirroring | |
964 | all of perlcc's output to both the screen and to a log file). If no B<-log> | |
965 | tag is given, then the default verbose level is 7 (ie: outputting all of | |
966 | perlcc's output to STDERR). | |
967 | ||
968 | NOTE: Because of buffering concerns, you CANNOT shadow the output of '-run' to | |
969 | both a file, and to the screen! Suggestions are welcome on how to overcome this | |
970 | difficulty, but for now it simply does not work properly, and hence will only go | |
971 | to the screen. | |
972 | ||
973 | =item -log <logname> | |
974 | ||
975 | Opens, for append, a logfile to save some or all of the text for a given | |
976 | compile command. No rewrite version is available, so this needs to be done | |
977 | manually. | |
978 | ||
979 | =item -argv <arguments> | |
980 | ||
ca24dfc6 | 981 | In combination with C<-run> or C<-e>, tells perlcc to run the resulting |
52cebf5e EP |
982 | executable with the string B<arguments> as @ARGV. |
983 | ||
984 | =item -sav | |
985 | ||
986 | Tells perl to save the intermediate C code. Usually, this C code is the name | |
987 | of the perl code, plus '.c'; 'perlcode.p' gets generated in 'perlcode.p.c', | |
ca24dfc6 | 988 | for example. If used with the C<-e> operator, you need to tell perlcc where to |
52cebf5e EP |
989 | save resulting executables. |
990 | ||
991 | =item -gen | |
992 | ||
993 | Tells perlcc to only create the intermediate C code, and not compile the | |
994 | results. Does an implicit B<-sav>, saving the C code rather than deleting it. | |
995 | ||
996 | =item -run | |
997 | ||
998 | Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE | |
999 | B<-run> FLAG TO B<perlcc>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS | |
1000 | ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING. | |
1001 | ||
1002 | =item -prog | |
1003 | ||
1004 | Indicate that the programs at the command line are programs, and should be | |
1005 | compiled as such. B<perlcc> will automatically determine files to be | |
1006 | programs if they have B<.p>, B<.pl>, B<.bat> extensions. | |
1007 | ||
1008 | =item -mod | |
1009 | ||
1010 | Indicate that the programs at the command line are modules, and should be | |
1011 | compiled as such. B<perlcc> will automatically determine files to be | |
1012 | modules if they have the extension B<.pm>. | |
1013 | ||
1014 | =back | |
1015 | ||
1016 | =head1 ENVIRONMENT | |
1017 | ||
1018 | Most of the work of B<perlcc> is done at the command line. However, you can | |
1019 | change the heuristic which determines what is a module and what is a program. | |
1020 | As indicated above, B<perlcc> assumes that the extensions: | |
1021 | ||
1022 | .p$, .pl$, and .bat$ | |
1023 | ||
1024 | indicate a perl program, and: | |
1025 | ||
1026 | .pm$ | |
1027 | ||
1028 | indicate a library, for the purposes of creating executables. And furthermore, | |
ef712cf7 | 1029 | by default, these extensions will be replaced (and dropped) in the process of |
52cebf5e EP |
1030 | creating an executable. |
1031 | ||
1032 | To change the extensions which are programs, and which are modules, set the | |
1033 | environmental variables: | |
1034 | ||
1035 | PERL_SCRIPT_EXT | |
1036 | PERL_MODULE_EXT | |
1037 | ||
1038 | These two environmental variables take colon-separated, legal perl regular | |
1039 | expressions, and are used by perlcc to decide which objects are which. | |
1040 | For example: | |
1041 | ||
1042 | setenv PERL_SCRIPT_EXT '.prl$:.perl$' | |
1043 | prompt% perlcc sample.perl | |
1044 | ||
1045 | will compile the script 'sample.perl' into the executable 'sample', and | |
1046 | ||
1047 | setenv PERL_MODULE_EXT '.perlmod$:.perlmodule$' | |
1048 | ||
1049 | prompt% perlcc sample.perlmod | |
1050 | ||
1051 | will compile the module 'sample.perlmod' into the shared object | |
1052 | 'sample.so' | |
1053 | ||
1054 | NOTE: the '.' in the regular expressions for PERL_SCRIPT_EXT and PERL_MODULE_EXT | |
1055 | is a literal '.', and not a wild-card. To get a true wild-card, you need to | |
1056 | backslash the '.'; as in: | |
1057 | ||
1058 | setenv PERL_SCRIPT_EXT '\.\.\.\.\.' | |
1059 | ||
1060 | which would have the effect of compiling ANYTHING (except what is in | |
1061 | PERL_MODULE_EXT) into an executable with 5 less characters in its name. | |
1062 | ||
9636a016 GS |
1063 | The PERLCC_OPTS environment variable can be set to the default flags |
1064 | that must be used by the compiler. | |
1065 | ||
1066 | The PERLCC_TIMEOUT environment variable can be set to the number of | |
1067 | seconds to wait for the backends before giving up. This is sometimes | |
1068 | necessary to avoid some compilers taking forever to compile the | |
1069 | generated output. May not work on Windows and similar platforms. | |

1071 | =head1 FILES |
1072 | ||
1073 | 'perlcc' uses a temporary file when you use the B<-e> option to evaluate | |
1074 | text and compile it. This temporary file is 'perlc$$.p'. The temporary C code is | |
1075 | perlc$$.p.c, and the temporary executable is perlc$$. | |
1076 | ||
1077 | When you use '-run' and don't save your executable, the temporary executable is | |
1078 | perlc$$ | |
1079 | ||
1080 | =head1 BUGS | |
1081 | ||
9636a016 GS |
1082 | The whole compiler suite (C<perlcc> included) should be considered very |
1083 | experimental. Use for production purposes is strongly discouraged. | |
1084 | ||
52cebf5e | 1085 | perlcc currently cannot compile shared objects on Win32. This should be fixed |
9636a016 GS |
1086 | in future. |
1087 | ||
1088 | Bugs in the various compiler backends still exist, and are perhaps too | |
1089 | numerous to list here. | |
