1 | This file contains a description of all the shell variables whose value is |
2 | determined by the Configure script. Variables intended for use in C |
ebc74a4b |
3 | programs (e.g. I_UNISTD) are already described in config_h.SH. [`configpm' |
4 | generates pod documentation for Config.pm from this file--please try to keep |
5 | the formatting regular.] |

10 | the value is reset to a plain "Mcc" and is not useful. |

12 | _a (Unix.U): |
13 | This variable defines the extension used for ordinary libraries. |
14 | For unix, it is '.a'. The '.' is included. Other possible |
15 | values include '.lib'. |
16 | |
17 | _exe (Unix.U): |
18 | This variable defines the extension used for executable files. |
19 | For unix it is empty. Other possible values include '.exe'. |
20 | |
21 | _o (Unix.U): |
22 | This variable defines the extension used for object files. |
23 | For unix, it is '.o'. The '.' is included. Other possible |
24 | values include '.obj'. |
25 | |
26 | afs (afs.U): |
27 | This variable is set to 'true' if AFS (Andrew File System) is used |
28 | on the system, 'false' otherwise. It is possible to override this |
29 | with a hint value or command line option, but you'd better know |
30 | what you are doing. |
31 | |
d7418ba7 |
32 | alignbytes (alignbytes.U): |
33 | This variable holds the number of bytes required to align a |
34 | double. Usual values are 2, 4 and 8. |

45 | apiversion (patchlevel.U): |
46 | This is a number which identifies the lowest version of perl |
47 | to have an API (for XS extensions) compatible with the present |
48 | version. For example, for 5.005_01, the apiversion should be |
49 | 5.005, since 5.005_01 should be binary compatible with 5.005. |
50 | This should probably be incremented manually somehow, perhaps |
51 | from patchlevel.h. For now, we'll guess maintenance subversions |
52 | will retain binary compatibility. |

2062 | We try to be flexible about how much of the version number |
2063 | to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the |
2064 | same for this package, hints files might just be os_4.0 or |
2065 | os_4.1, etc., not keeping separate files for each little release. |

2219 | /bin/pdksh, /bin/ash, /bin/bash, or even something such as |
2220 | D:/bin/sh.exe. |
fb87c415 |
2221 | This unit comes before Options.U, so you can't set sh with a '-D' |
d7418ba7 |
2222 | option, though you can override this (and startsh) |

2244 | One way to do this on some systems is to set the environment variable |
2245 | LD_RUN_PATH to the directory that will be the final location of the |
2246 | shared libperl.so. The makefile can use this with something like |
2247 | $shrpenv $(CC) -o perl perlmain.o $libperl $libs |
2248 | Typical values are |
