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 | |

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 |

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. |

2273 | nm --dynamic is *required* to get symbols from an ELF library which |
2274 | has been stripped, but nm --dynamic is *fatal* on an archive library. |

2320 | setting defaults. It is set to '' if we can't figure it out. |
2321 | We try to be flexible about how much of the version number |
2322 | to keep, e.g. if 4.1.1, 4.1.2, and 4.1.3 are essentially the |
2323 | same for this package, hints files might just be os_4.0 or |

fb87c415 |
2501 | This unit comes before Options.U, so you can't set sh with a '-D' |

2503 | with '-O -Dsh=/bin/whatever -Dstartsh=whatever' |

2521 | shrpenv (libperl.U): |
2522 | If the user builds a shared libperl.so, then we need to tell the |
2523 | 'perl' executable where it will be able to find the installed libperl.so. |
2524 | One way to do this on some systems is to set the environment variable |
2525 | LD_RUN_PATH to the directory that will be the final location of the |
2526 | shared libperl.so. The makefile can use this with something like |
2527 | $shrpenv $(CC) -o perl perlmain.o $libperl $libs |
2528 | Typical values are |
2529 | shrpenv="env LD_RUN_PATH=$archlibexp/CORE" |
2530 | or |
2531 | shrpenv='' |
2532 | See the main perl Makefile.SH for actual working usage. |
2533 | Alternatively, we might be able to use a command line option such |
2534 | as -R $archlibexp/CORE (Solaris, NetBSD) or -Wl,-rpath |
