| 175 | .IX Header "DESCRIPTION" |
| 176 | \&\fIperlcc\fR creates standalone executables from Perl programs, using the |
| 177 | code generators provided by the B module. At present, you may |
| 178 | either create executable Perl bytecode, using the \f(CW\*(C`\-B\*(C'\fR option, or |
| 179 | generate and compile C files using the standard and 'optimised' C |
| 180 | backends. |
| 181 | .PP |
| 182 | The code generated in this way is not guaranteed to work. The whole |
| 183 | codegen suite (\f(CW\*(C`perlcc\*(C'\fR included) should be considered \fBvery\fR |
| 184 | experimental. Use for production purposes is strongly discouraged. |
| 185 | .SH "OPTIONS" |
| 186 | .IX Header "OPTIONS" |
| 187 | .IP "\-L\fIlibrary directories\fR" 4 |
| 188 | .IX Item "-Llibrary directories" |
| 189 | Adds the given directories to the library search path when C code is |
| 190 | passed to your C compiler. |
| 191 | .IP "\-I\fIinclude directories\fR" 4 |
| 192 | .IX Item "-Iinclude directories" |
| 193 | Adds the given directories to the include file search path when C code is |
| 194 | passed to your C compiler; when using the Perl bytecode option, adds the |
| 195 | given directories to Perl's include path. |
| 196 | .IP "\-o \fIoutput file name\fR" 4 |
| 197 | .IX Item "-o output file name" |
| 198 | Specifies the file name for the final compiled executable. |
| 199 | .IP "\-c \fIC file name\fR" 4 |
| 200 | .IX Item "-c C file name" |
| 201 | Create C code only; do not compile to a standalone binary. |
| 202 | .IP "\-e \fIperl code\fR" 4 |
| 203 | .IX Item "-e perl code" |
| 204 | Compile a one\-liner, much the same as \f(CW\*(C`perl \-e '...'\*(C'\fR |
| 205 | .IP "\-S" 4 |
| 206 | .IX Item "-S" |
| 207 | Do not delete generated C code after compilation. |
| 208 | .IP "\-B" 4 |
| 209 | .IX Item "-B" |
| 210 | Use the Perl bytecode code generator. |
| 211 | .IP "\-O" 4 |
| 212 | .IX Item "-O" |
| 213 | Use the 'optimised' C code generator. This is more experimental than |
| 214 | everything else put together, and the code created is not guaranteed to |
| 215 | compile in finite time and memory, or indeed, at all. |
| 216 | .IP "\-v" 4 |
| 217 | .IX Item "-v" |
| 218 | Increase verbosity of output; can be repeated for more verbose output. |
| 219 | .IP "\-r" 4 |
| 220 | .IX Item "-r" |
| 221 | Run the resulting compiled script after compiling it. |
| 222 | .IP "\-log" 4 |
| 223 | .IX Item "-log" |
| 224 | Log the output of compiling to a file rather than to stdout. |
