45 | =head1 NAME |
46 | ||
47 | xsubpp - compiler to convert Perl XS code into C code | |
48 | ||
49 | =head1 SYNOPSIS | |
50 | ||
6b09c160 | 51 | B<xsubpp> [B<-v>] [B<-except>] [B<-s pattern>] [B<-prototypes>] [B<-noversioncheck>] [B<-nolinenumbers>] [B<-nooptimize>] [B<-typemap typemap>] [B<-output filename>]... file.xs |

53 | =head1 DESCRIPTION | |
54 | ||
b26a54d0 GS |
55 | This compiler is typically run by the makefiles created by L<ExtUtils::MakeMaker>. |
56 | ||
75f92628 AD |
57 | I<xsubpp> will compile XS code into C code by embedding the constructs |
58 | necessary to let C functions manipulate Perl values and creates the glue | |
59 | necessary to let Perl access those functions. The compiler uses typemaps to | |
60 | determine how to map C function parameters and variables to Perl values. | |
61 | ||
62 | The compiler will search for typemap files called I<typemap>. It will use | |
63 | the following search path to find default typemaps, with the rightmost | |
64 | typemap taking precedence. | |
65 | ||
66 | ../../../typemap:../../typemap:../typemap:typemap | |
67 | ||
6b09c160 YST |
68 | It will also use a default typemap installed as C<ExtUtils::typemap>. |
69 | ||
75f92628 AD |
70 | =head1 OPTIONS |
71 | ||
b26a54d0 GS |
72 | Note that the C<XSOPT> MakeMaker option may be used to add these options to |
73 | any makefiles generated by MakeMaker. | |
74 | ||

0ab125c1 NIS |
77 | =item B<-hiertype> |
78 | ||
863b2ca0 | 79 | Retains '::' in type names so that C++ hierarchical types can be mapped. |
0ab125c1 | 80 | |
75f92628 AD |
81 | =item B<-except> |
82 | ||
83 | Adds exception handling stubs to the C code. | |
84 | ||
85 | =item B<-typemap typemap> | |
86 | ||
87 | Indicates that a user-supplied typemap should take precedence over the | |
88 | default typemaps. This option may be used multiple times, with the last | |
89 | typemap having the highest precedence. | |
90 | ||
6b09c160 YST |
91 | =item B<-output filename> |
92 | ||
93 | Specifies the name of the output file to generate. If no file is | |
94 | specified, output will be written to standard output. | |
95 | ||
8e07c86e AD |
96 | =item B<-v> |
97 | ||
98 | Prints the I<xsubpp> version number to standard output, then exits. | |
99 | ||
8fc38fda | 100 | =item B<-prototypes> |
382b8d97 | 101 | |
8fc38fda | 102 | By default I<xsubpp> will not automatically generate prototype code for |
103 | all xsubs. This flag will enable prototypes. | |
104 | ||
105 | =item B<-noversioncheck> | |
106 | ||
107 | Disables the run time test that determines if the object file (derived | |
108 | from the C<.xs> file) and the C<.pm> files have the same version | |
109 | number. | |
382b8d97 | 110 | |
6f1abe2b JT |
111 | =item B<-nolinenumbers> |
112 | ||
113 | Prevents the inclusion of `#line' directives in the output. | |
114 | ||
b26a54d0 GS |
115 | =item B<-nooptimize> |
116 | ||
117 | Disables certain optimizations. The only optimization that is currently | |
118 | affected is the use of I<target>s by the output C code (see L<perlguts>). | |
119 | This may significantly slow down the generated code, but this is the way | |
120 | B<xsubpp> of 5.005 and earlier operated. | |
121 | ||
11416672 GS |
122 | =item B<-noinout> |
123 | ||
124 | Disable recognition of C<IN>, C<OUT_LIST> and C<INOUT_LIST> declarations. | |
125 | ||
126 | =item B<-noargtypes> | |
127 | ||
128 | Disable recognition of ANSI-like descriptions of function signature. | |
129 | ||
6b09c160 YST |
130 | =item B<-C++> |
131 | ||
132 | Currently doesn't do anything at all. This flag has been a no-op for | |
133 | many versions of perl, at least as far back as perl5.003_07. It's | |
134 | allowed here for backwards compatibility. | |
