| 164 | .IX Header "DESCRIPTION" |
| 165 | The Config module contains all the information that was available to |
| 166 | the \f(CW\*(C`Configure\*(C'\fR program at Perl build time (over 900 values). |
| 167 | .PP |
| 168 | Shell variables from the \fIconfig.sh\fR file (written by Configure) are |
| 169 | stored in the readonly-variable \f(CW%Config\fR, indexed by their names. |
| 170 | .PP |
| 171 | Values stored in config.sh as 'undef' are returned as undefined |
| 172 | values. The perl \f(CW\*(C`exists\*(C'\fR function can be used to check if a |
| 173 | named variable exists. |
| 174 | .IP "\fImyconfig()\fR" 4 |
| 175 | .IX Item "myconfig()" |
| 176 | Returns a textual summary of the major perl configuration values. |

| 178 | .IP "\fIconfig_sh()\fR" 4 |
| 179 | .IX Item "config_sh()" |

| 182 | .IP "config_re($regex)" 4 |
| 183 | .IX Item "config_re($regex)" |

| 186 | .IP "config_vars(@names)" 4 |
| 187 | .IX Item "config_vars(@names)" |

| 227 | .IX Header "WARNING" |
| 228 | Because this information is not stored within the perl executable |
| 229 | itself it is possible (but unlikely) that the information does not |
| 230 | relate to the actual perl binary which is being used to access it. |
| 231 | .PP |
| 232 | The Config module is installed into the architecture and version |
| 233 | specific library directory ($Config{installarchlib}) and it checks the |
| 234 | perl version number when loaded. |
| 235 | .PP |
| 236 | The values stored in config.sh may be either single-quoted or |
| 237 | double\-quoted. Double-quoted strings are handy for those cases where you |
| 238 | need to include escape sequences in the strings. To avoid runtime variable |
| 239 | interpolation, any \f(CW\*(C`$\*(C'\fR and \f(CW\*(C`@\*(C'\fR characters are replaced by \f(CW\*(C`\e$\*(C'\fR and |
| 240 | \&\f(CW\*(C`\e@\*(C'\fR, respectively. This isn't foolproof, of course, so don't embed \f(CW\*(C`\e$\*(C'\fR |
| 241 | or \f(CW\*(C`\e@\*(C'\fR in double-quoted strings unless you're willing to deal with the |
| 242 | consequences. (The slashes will end up escaped and the \f(CW\*(C`$\*(C'\fR or \f(CW\*(C`@\*(C'\fR will |
| 243 | trigger variable interpolation) |
| 244 | .SH "GLOSSARY" |
| 245 | .IX Header "GLOSSARY" |
| 246 | Most \f(CW\*(C`Config\*(C'\fR variables are determined by the \f(CW\*(C`Configure\*(C'\fR script |
| 247 | on platforms supported by it (which is most \s-1UNIX\s0 platforms). Some |
| 248 | platforms have custom-made \f(CW\*(C`Config\*(C'\fR variables, and may thus not have |
| 249 | some of the variables described below, or may have extraneous variables |
| 250 | specific to that particular port. See the port specific documentation |

| 327 | The three variables, api_revision, api_version, and |

| 333 | .Sp |

| 337 | perl library directory tree structured like the default one. |
| 338 | See \f(CW\*(C`INSTALL\*(C'\fR for how this works. The versioned site_perl |
| 339 | directory was introduced in 5.005, so that is the lowest |
| 340 | possible value. The version list appropriate for the current |

| 5539 | .Sp |
| 5540 | This variable describes the \f(CW\*(C`style\*(C'\fR of the perl installation. |
| 5541 | This is intended to be useful for tools that need to |
| 5542 | manipulate entire perl distributions. Perl itself doesn't use |
| 5543 | this to find its libraries \*(-- the library directories are |
| 5544 | stored directly in \fIConfig.pm\fR. Currently, there are only two |
| 5545 | styles: \f(CW\*(C`lib\*(C'\fR and \fIlib/perl5\fR. The default library locations |
| 5546 | (e.g. privlib, sitelib) are either \fI$prefix/lib\fR or |
| 5547 | \&\fI$prefix/lib/perl5\fR. The former is useful if \f(CW$prefix\fR is a |
| 5548 | directory dedicated to perl (e.g. \fI/opt/perl\fR), while the latter |
| 5549 | is useful if \f(CW$prefix\fR is shared by many packages, e.g. if |
| 5550 | \&\f(CW$prefix\fR=\fI/usr/local\fR. |
| 5551 | .Sp |
| 5552 | Unfortunately, while this \f(CW\*(C`style\*(C'\fR variable is used to set |
| 5553 | defaults for all three directory hierarchies (core, vendor, and |
| 5554 | site), there is no guarantee that the same style is actually |
| 5555 | appropriate for all those directories. For example, \f(CW$prefix\fR |
| 5556 | might be \fI/opt/perl\fR, but \f(CW$siteprefix\fR might be \fI/usr/local\fR. |
| 5557 | (Perhaps, in retrospect, the \f(CW\*(C`lib\*(C'\fR style should never have been |
| 5558 | supported, but it did seem like a nice idea at the time.) |
| 5559 | .Sp |
| 5560 | The situation is even less clear for tools such as MakeMaker |
| 5561 | that can be used to install additional modules into |
| 5562 | non-standard places. For example, if a user intends to install |
| 5563 | a module into a private directory (perhaps by setting \f(CW\*(C`PREFIX\*(C'\fR on |
| 5564 | the \fIMakefile.PL\fR command line), then there is no reason to |
| 5565 | assume that the Configure-time \f(CW$installstyle\fR setting will be |
| 5566 | relevant for that \f(CW\*(C`PREFIX\*(C'\fR. |

| 5570 | .Sp |
| 5571 | For compatibility with \fIperl5.005\fR and earlier, the default |

| 8209 | If set, this symbol indicates that only the version-specific |
| 8210 | components of a perl installation should be installed. |
| 8211 | This may be useful for making a test installation of a new |
| 8212 | version without disturbing the existing installation. |
| 8213 | Setting versiononly is equivalent to setting installperl's \-v option. |
| 8214 | In particular, the non-versioned scripts and programs such as |
| 8215 | a2p, c2ph, h2xs, pod2*, and perldoc are not installed |
| 8216 | (see \f(CW\*(C`INSTALL\*(C'\fR for a more complete list). Nor are the man |
| 8217 | pages installed. |

| 8228 | .IX Item "voidflags" |

| 8230 | .Sp |
| 8231 | This variable contains the eventual value of the \f(CW\*(C`VOIDFLAGS\*(C'\fR symbol, |

| 8251 | This variable holds the name of the compiler compiler we |

| 8258 | This variable contains any additional yacc flags desired by the |

| 8273 | .Sp |
| 8274 | This variable is used internally by Configure to determine the |
| 8275 | full pathname (if any) of the zip program. After Configure runs, |
| 8276 | the value is reset to a plain \f(CW\*(C`zip\*(C'\fR and is not useful. |
