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.] |

7 | _a (Unix.U): |
8 | This variable defines the extension used for ordinary libraries. |
9 | For unix, it is '.a'. The '.' is included. Other possible |
10 | values include '.lib'. |
11 | |
12 | _exe (Unix.U): |
13 | This variable defines the extension used for executable files. |
14 | For unix it is empty. Other possible values include '.exe'. |
15 | |
16 | _o (Unix.U): |
17 | This variable defines the extension used for object files. |
18 | For unix, it is '.o'. The '.' is included. Other possible |
19 | values include '.obj'. |
20 | |
21 | afs (afs.U): |
22 | This variable is set to 'true' if AFS (Andrew File System) is used |
23 | on the system, 'false' otherwise. It is possible to override this |
24 | with a hint value or command line option, but you'd better know |
25 | what you are doing. |
26 | |
d7418ba7 |
27 | alignbytes (alignbytes.U): |
28 | This variable holds the number of bytes required to align a |
29 | double. Usual values are 2, 4 and 8. |

31 | ansi2knr (ansi2knr.U): |
32 | This variable is set if the user needs to run ansi2knr. |
33 | Currently, this is not supported, so we just abort. |
34 | |
dfe9444c |
35 | aphostname (d_gethname.U): |
36 | Thie variable contains the command which can be used to compute the |
37 | host name. The command is fully qualified by its absolute path, to make |
38 | it safe when used by a process with super-user privileges. |

40 | apiversion (patchlevel.U): |
41 | This is a number which identifies the lowest version of perl |
42 | to have an API (for XS extensions) compatible with the present |
43 | version. For example, for 5.005_01, the apiversion should be |
44 | 5.005, since 5.005_01 should be binary compatible with 5.005. |
45 | This should probably be incremented manually somehow, perhaps |
46 | from patchlevel.h. For now, we'll guess maintenance subversions |
47 | will retain binary compatibility. |

2437 | to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the |
2438 | same for this package, hints files might just be os_4.0 or |

2548 | |
2549 | rd_nodata (nblock_io.U): |
2550 | This variable holds the return code from read() when no data is |
2551 | present. It should be -1, but some systems return 0 when O_NDELAY is |

2578 | must be prepared to deal with ~name expansion. |
2579 | |

2615 | D:/bin/sh.exe. |
732c9516 |
2616 | This unit comes before Options.U, so you can't set sh with a -D |
d7418ba7 |
2617 | option, though you can override this (and startsh) |
732c9516 |
2618 | with -O -Dsh=/bin/whatever -Dstartsh=whatever |

2638 | 'perl' executable where it will be able to find the installed libperl.so. |
2639 | One way to do this on some systems is to set the environment variable |
2640 | LD_RUN_PATH to the directory that will be the final location of the |
2641 | shared libperl.so. The makefile can use this with something like |
ccc7f9b3 |
2642 | $shrpenv $(CC) -o perl perlmain.o $libperl $libs |
c43cd16b |
2643 | Typical values are |

2888 | the value is reset to a plain "uname" and is not useful. |
2889 | |
2890 | uniq (Loc.U): |
2891 | This variable is be used internally by Configure to determine the |
2892 | full pathname (if any) of the uniq program. After Configure runs, |

2909 | This variable contains y if the malloc that comes with this package |
2910 | is desired over the system's version of malloc. People often include |
2911 | special versions of malloc for effiency, but such versions are often |
2912 | less portable. See also mallocsrc and mallocobj. |

2923 | for users to skip the Opcode extension from the Configure |
2924 | command line. |

2939 | This variable is set to true when the user agrees to use sfio. |
2940 | It is set to false when sfio is not available or when the user |
2941 | explicitely requests not to use sfio. It is here primarily so |
2942 | that command-line settings can override the auto-detection of |

2982 | xlibpth (libpth.U): |
2983 | This variable holds extra path (space-separated) used to find |
