---|
907 | =head1 DESCRIPTION |
---|
908 | |
---|
909 | 'perlcc' is the frontend into the perl compiler. Typing 'perlcc a.p' |
---|
910 | compiles the code inside a.p into a standalone executable, and |
---|
911 | perlcc A.pm will compile into a shared object, A.so, suitable for inclusion |
---|
912 | into a perl program via "use A". |
---|
913 | |
---|
914 | There are quite a few flags to perlcc which help with such issues as compiling |
---|
915 | programs in bulk, testing compiled programs for compatibility with the |
---|
916 | interpreter, and controlling. |
---|
917 | |
---|
918 | =head1 OPTIONS |
---|
919 | |
---|
920 | =over 4 |
---|
921 | |
---|
922 | =item -L < library_directories > |
---|
923 | |
---|
924 | Adds directories in B<library_directories> to the compilation command. |
---|
925 | |
---|
926 | =item -I < include_directories > |
---|
927 | |
---|
928 | Adds directories inside B<include_directories> to the compilation command. |
---|
929 | |
---|
930 | =item -C < c_code_name > |
---|
931 | |
---|
932 | Explicitly gives the name B<c_code_name> to the generated file containing |
---|
933 | the C code which is to be compiled. Can only be used if compiling one file |
---|
934 | on the command line. |
---|
935 | |
---|
936 | =item -o < executable_name > |
---|
937 | |
---|
938 | Explicitly gives the name B<executable_name> to the executable which is to be |
---|
939 | compiled. Can only be used if compiling one file on the command line. |
---|
940 | |
---|
941 | =item -e < perl_line_to_execute> |
---|
942 | |
---|
943 | Compiles 'one liners', in the same way that B<perl -e> runs text strings at |
---|
944 | the command line. Default is to have the 'one liner' be compiled, and run all |
---|
945 | in one go (see B<-run>); giving the B<-o> flag saves the resultant executable, |
---|
946 | rather than throwing it away. Use '-argv' to pass arguments to the executable |
---|
947 | created. |
---|
948 | |
---|
949 | =item -b |
---|
950 | |
---|
951 | Generates bytecode instead of C code. |
---|
952 | |
---|
953 | =item -opt |
---|
954 | |
---|
955 | Uses the optimized C backend (C<B::CC>)rather than the simple C backend |
---|
956 | (C<B::C>). Beware that the optimized C backend creates very large |
---|
957 | switch structures and structure initializations. Many C compilers |
---|
958 | find it a challenge to compile the resulting output in finite amounts |
---|
959 | of time. Many Perl features such as C<goto LABEL> are also not |
---|
960 | supported by the optimized C backend. The simple C backend should |
---|
961 | work in more instances, but can only offer modest speed increases. |
---|
962 | |
---|
963 | =item -regex <rename_regex> |
---|
964 | |
---|
965 | Gives a rule B<rename_regex> - which is a legal perl regular expression - to |
---|
966 | create executable file names. |
---|
967 | |
---|
968 | =item -verbose <verbose_level> |
---|
969 | |
---|
970 | Show exactly what steps perlcc is taking to compile your code. You can |
---|
971 | change the verbosity level B<verbose_level> much in the same way that |
---|
972 | the C<-D> switch changes perl's debugging level, by giving either a |
---|
973 | number which is the sum of bits you want or a list of letters |
---|
974 | representing what you wish to see. Here are the verbosity levels so |
---|
975 | far : |
---|
976 | |
---|
977 | Bit 1(g): Code Generation Errors to STDERR |
---|
978 | Bit 2(a): Compilation Errors to STDERR |
---|
979 | Bit 4(t): Descriptive text to STDERR |
---|
980 | Bit 8(f): Code Generation Errors to file (B<-log> flag needed) |
---|
981 | Bit 16(c): Compilation Errors to file (B<-log> flag needed) |
---|
982 | Bit 32(d): Descriptive text to file (B<-log> flag needed) |
---|
983 | |
---|
984 | If the B<-log> tag is given, the default verbose level is 63 (ie: mirroring |
---|
985 | all of perlcc's output to both the screen and to a log file). If no B<-log> |
---|
986 | tag is given, then the default verbose level is 7 (ie: outputting all of |
---|
987 | perlcc's output to STDERR). |
---|
988 | |
---|
989 | NOTE: Because of buffering concerns, you CANNOT shadow the output of '-run' to |
---|
990 | both a file, and to the screen! Suggestions are welcome on how to overcome this |
---|
991 | difficulty, but for now it simply does not work properly, and hence will only go |
---|
992 | to the screen. |
---|
993 | |
---|
994 | =item -log <logname> |
---|
995 | |
---|
996 | Opens, for append, a logfile to save some or all of the text for a given |
---|
997 | compile command. No rewrite version is available, so this needs to be done |
---|
998 | manually. |
---|
999 | |
---|
1000 | =item -argv <arguments> |
---|
1001 | |
---|
1002 | In combination with C<-run> or C<-e>, tells perlcc to run the resulting |
---|
1003 | executable with the string B<arguments> as @ARGV. |
---|
1004 | |
---|
1005 | =item -sav |
---|
1006 | |
---|
1007 | Tells perl to save the intermediate C code. Usually, this C code is the name |
---|
1008 | of the perl code, plus '.c'; 'perlcode.p' gets generated in 'perlcode.p.c', |
---|
1009 | for example. If used with the C<-e> operator, you need to tell perlcc where to |
---|
1010 | save resulting executables. |
---|
1011 | |
---|
1012 | =item -gen |
---|
1013 | |
---|
1014 | Tells perlcc to only create the intermediate C code, and not compile the |
---|
1015 | results. Does an implicit B<-sav>, saving the C code rather than deleting it. |
---|
1016 | |
---|
1017 | =item -run |
---|
1018 | |
---|
1019 | Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE |
---|
1020 | B<-run> FLAG TO B<perlcc>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS |
---|
1021 | ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING. |
---|
1022 | |
---|
1023 | =item -prog |
---|
1024 | |
---|
1025 | Indicate that the programs at the command line are programs, and should be |
---|
1026 | compiled as such. B<perlcc> will automatically determine files to be |
---|
1027 | programs if they have B<.p>, B<.pl>, B<.bat> extensions. |
---|
1028 | |
---|
1029 | =item -mod |
---|
1030 | |
---|
1031 | Indicate that the programs at the command line are modules, and should be |
---|
1032 | compiled as such. B<perlcc> will automatically determine files to be |
---|
1033 | modules if they have the extension B<.pm>. |
---|
1034 | |
---|
1035 | =back |
---|
1036 | |
---|
1037 | =head1 ENVIRONMENT |
---|
1038 | |
---|
1039 | Most of the work of B<perlcc> is done at the command line. However, you can |
---|
1040 | change the heuristic which determines what is a module and what is a program. |
---|
1041 | As indicated above, B<perlcc> assumes that the extensions: |
---|
1042 | |
---|
1043 | .p$, .pl$, and .bat$ |
---|
1044 | |
---|
1045 | indicate a perl program, and: |
---|
1046 | |
---|
1047 | .pm$ |
---|
1048 | |
---|
1049 | indicate a library, for the purposes of creating executables. And furthermore, |
---|
1050 | by default, these extensions will be replaced (and dropped) in the process of |
---|
1051 | creating an executable. |
---|
1052 | |
---|
1053 | To change the extensions which are programs, and which are modules, set the |
---|
1054 | environmental variables: |
---|
1055 | |
---|
1056 | PERL_SCRIPT_EXT |
---|
1057 | PERL_MODULE_EXT |
---|
1058 | |
---|
1059 | These two environmental variables take colon-separated, legal perl regular |
---|
1060 | expressions, and are used by perlcc to decide which objects are which. |
---|
1061 | For example: |
---|
1062 | |
---|
1063 | setenv PERL_SCRIPT_EXT '.prl$:.perl$' |
---|
1064 | prompt% perlcc sample.perl |
---|
1065 | |
---|
1066 | will compile the script 'sample.perl' into the executable 'sample', and |
---|
1067 | |
---|
1068 | setenv PERL_MODULE_EXT '.perlmod$:.perlmodule$' |
---|
1069 | |
---|
1070 | prompt% perlcc sample.perlmod |
---|
1071 | |
---|
1072 | will compile the module 'sample.perlmod' into the shared object |
---|
1073 | 'sample.so' |
---|
1074 | |
---|
1075 | NOTE: the '.' in the regular expressions for PERL_SCRIPT_EXT and PERL_MODULE_EXT |
---|
1076 | is a literal '.', and not a wild-card. To get a true wild-card, you need to |
---|
1077 | backslash the '.'; as in: |
---|
1078 | |
---|
1079 | setenv PERL_SCRIPT_EXT '\.\.\.\.\.' |
---|
1080 | |
---|
1081 | which would have the effect of compiling ANYTHING (except what is in |
---|
1082 | PERL_MODULE_EXT) into an executable with 5 less characters in its name. |
---|
1083 | |
---|
1084 | The PERLCC_OPTS environment variable can be set to the default flags |
---|
1085 | that must be used by the compiler. |
---|
1086 | |
---|
1087 | The PERLCC_TIMEOUT environment variable can be set to the number of |
---|
1088 | seconds to wait for the backends before giving up. This is sometimes |
---|
1089 | necessary to avoid some compilers taking forever to compile the |
---|
1090 | generated output. May not work on Windows and similar platforms. |
---|
1091 | |
---|
1092 | =head1 FILES |
---|
1093 | |
---|
1094 | 'perlcc' uses a temporary file when you use the B<-e> option to evaluate |
---|
1095 | text and compile it. This temporary file is 'perlc$$.p'. The temporary C code is |
---|
1096 | perlc$$.p.c, and the temporary executable is perlc$$. |
---|
1097 | |
---|
1098 | When you use '-run' and don't save your executable, the temporary executable is |
---|
1099 | perlc$$ |
---|
1100 | |
---|
1101 | =head1 BUGS |
---|
1102 | |
---|
1103 | The whole compiler suite (C<perlcc> included) should be considered very |
---|
1104 | experimental. Use for production purposes is strongly discouraged. |
---|
1105 | |
---|
1106 | perlcc currently cannot compile shared objects on Win32. This should be fixed |
---|
1107 | in future. |
---|
1108 | |
---|
1109 | Bugs in the various compiler backends still exist, and are perhaps too |
---|
1110 | numerous to list here. |
