985 | and friends. |
986 | |
987 | i_varargs (i_varhdr.U): |
988 | This variable conditionally defines I_VARARGS, which indicates |

998 | |
999 | installbin (bin.U): |
1000 | This variable is the same as binexp unless AFS is running in which case |
1001 | the user is explicitely prompted for it. This variable should always |
1002 | be used in your makefiles for maximum portability. |
1003 | |
1004 | installprivlib (privlib.U): |
1005 | This variable is really the same as privlibexp but may differ on |
1006 | those systems using AFS. For extra portability, only this variable |
1007 | should be used in makefiles. |
1008 | |
1009 | intsize (intsize.U): |
1010 | This variable contains the value of the INTSIZE symbol, |

1014 | large (models.U): |
1015 | This variable contains a flag which will tell the C compiler and loader |
1016 | to produce a program running with a large memory model. It is up to |
1017 | the Makefile to use this. |
1018 | |
1019 | ld (dlsrc.U): |
1020 | This variable indicates the program to be used to link |
1021 | libraries for dynamic loading. On some systems, it is 'ld'. |
1022 | On ELF systems, it should be $cc. Mostly, we'll try to respect |
1023 | the hint file setting. |
1024 | |
1025 | lddlflags (dlsrc.U): |
1026 | This variable contains any special flags that might need to be |
1027 | passed to $ld to create a shared library suitable for dynamic |
1028 | loading. It is up to the makefile to use it. For hpux, it |
1029 | should be -b. For sunos 4.1, it is empty. |
1030 | |
1031 | ldflags (ccflags.U): |
1032 | This variable contains any additional C loader flags desired by |
1033 | the user. It is up to the Makefile to use this. |
1034 | |
1035 | lib_ext (Unix.U): |
1036 | This variable defines the extension used for ordinary libraries. |
1037 | For unix, it is '.a'. The '.' is included. Other possible |
1038 | values include '.lib'. |
1039 | |
1040 | libperl (libperl.U): |
1041 | The perl executable is obtained by linking perlmain.c with |
1042 | libperl, any static extensions (usually just DynaLoader), |
1043 | and any other libraries needed on this system. libperl |
1044 | is usually libperl.a, but can also be libperl.so.xxx if |
1045 | the user wishes to build a perl executable with a shared |
1046 | library. |
1047 | |
1048 | libs (libs.U): |
1049 | This variable holds the additional libraries we want to use. |
1050 | It is up to the Makefile to deal with it. |
1051 | |
1052 | lns (lns.U): |
1053 | This variable holds the name of the command to make |
1054 | symbolic links (if they are supported). It can be used |
1055 | in the Makefile. It is either 'ln -s' or 'ln' |
1056 | |
1057 | lseektype (lseektype.U): |
1058 | This variable defines lseektype to be something like off_t, long, |
1059 | or whatever type is used to declare lseek offset's type in the |
1060 | kernel (which also appears to be lseek's return type). |
1061 | |
1062 | make (make.U): |
1063 | This variable sets the path to the 'make' command. It is |
1064 | here rather than in Loc.U so that users can override it |
1065 | with Configure -Dmake=pmake, or equivalent. |
1066 | |
1067 | make_set_make (make.U): |
1068 | Some versions of 'make' set the variable MAKE. Others do not. |
1069 | This variable contains the string to be included in Makefile.SH |
1070 | so that MAKE is set if needed, and not if not needed. |
1071 | Possible values are: |
1072 | make_set_make='#' # If your make program handles this for you, |
1073 | make_set_make=$make # if it doesn't. |
1074 | I used a comment character so that we can distinguish a |
1075 | 'set' value (from a previous config.sh or Configure -D option) |
1076 | from an uncomputed value. |
1077 | |
1078 | mallocobj (mallocsrc.U): |
1079 | This variable contains the name of the malloc.o that this package |
1080 | generates, if that malloc.o is preferred over the system malloc. |

1092 | |
1093 | man1dir (man1dir.U): |
1094 | This variable contains the name of the directory in which manual |
1095 | source pages are to be put. It is the responsibility of the |
1096 | Makefile.SH to get the value of this into the proper command. |
1097 | You must be prepared to do the ~name expansion yourself. |
1098 | |
1099 | man1ext (man1dir.U): |
1100 | This variable contains the extension that the manual page should |
1101 | have: one of 'n', 'l', or '1'. The Makefile must supply the '.'. |

1103 | |
1104 | man3dir (man3dir.U): |
1105 | This variable contains the name of the directory in which manual |

1109 | |
1110 | man3ext (man3dir.U): |
1111 | This variable contains the extension that the manual page should |
1112 | have: one of 'n', 'l', or '3'. The Makefile must supply the '.'. |

1117 | int, unsigned short, or whatever type is used to declare file |
1118 | modes for system calls. |
1119 | |
1120 | n (n.U): |
1121 | This variable contains the -n flag if that is what causes the echo |
1122 | command to suppress newline. Otherwise it is null. Correct usage is |
1123 | $echo $n "prompt for a question: $c". |
1124 | |
1125 | o_nonblock (nblock_io.U): |
1126 | This variable bears the symbol value to be used during open() or fcntl() |
1127 | to turn on non-blocking I/O for a file descriptor. If you wish to switch |
1128 | between blocking and non-blocking, you may try ioctl(FIOSNBIO) instead, |
1129 | but that is only supported by some devices. |
1130 | |
1131 | oldarchlib (oldarchlib.U): |
1132 | This variable holds the name of the directory in which perl5.000 |
1133 | and perl5.001 stored |
1134 | architecture-dependent public library files. |

1136 | oldarchlibexp (oldarchlib.U): |
1137 | This variable is the same as the oldarchlib variable, but is |
1138 | filename expanded at configuration time, for convenient use. |
1139 | |
1140 | optimize (ccflags.U): |
1141 | This variable contains any optimizer/debugger flag that should be used. |
1142 | It is up to the Makefile to use it. |
1143 | |
1144 | osname (Oldconfig.U): |
1145 | This variable contains the operating system name (e.g. sunos, |
1146 | solaris, hpux, etc.). It can be useful later on for setting |
1147 | defaults. Any spaces are replaced with underscores. It is set |
1148 | to a null string if we can't figure it out. |
1149 | |
1150 | pager (pager.U): |
1151 | This variable contains the name of the preferred pager on the system. |
1152 | Usual values are (the full pathnames of) more, less, pg, or cat. |
1153 | |
1154 | path_sep (Unix.U): |
1155 | This variable defines the character used to separate elements in |
1156 | the shell's PATH environment variable. On Unix, it is ':'. |
1157 | This is probably identical to Head.U's p_ variable and can |
1158 | probably be dropped. |
1159 | |
1160 | perladmin (perladmin.U): |
1161 | Electronic mail address of the perl5 administrator. |
1162 | |
1163 | prefix (prefix.U): |
1164 | This variable holds the name of the directory below which the |
1165 | user will install the package. Usually, this is /usr/local, and |
1166 | executables go in /usr/local/bin, library stuff in /usr/local/lib, |
1167 | man pages in /usr/local/man, etc. It is only used to set defaults |
1168 | for things in bin.U, mansrc.U, privlib.U, or scriptdir.U. |
1169 | |
1170 | privlib (privlib.U): |
1171 | This variable contains the eventual value of the PRIVLIB symbol, |
1172 | which is the name of the private library for this package. It may |
1173 | have a ~ on the front. It is up to the makefile to eventually create |
1174 | this directory while performing installation (with ~ substitution). |
1175 | |
1176 | privlibexp (privlib.U): |
1177 | This variable is the ~name expanded version of privlib, so that you |
1178 | may use it directly in Makefiles or shell scripts. |
1179 | |
1180 | prototype (prototype.U): |
1181 | This variable holds the eventual value of CAN_PROTOTYPE, which |

1193 | |
1194 | rd_nodata (nblock_io.U): |
1195 | This variable holds the return code from read() when no data is |
1196 | present. It should be -1, but some systems return 0 when O_NDELAY is |
1197 | used, which is a shame because you cannot make the difference between |
1198 | no data and an EOF.. Sigh! |
1199 | |
1200 | scriptdir (scriptdir.U): |
1201 | This variable holds the name of the directory in which the user wants |
1202 | to put publicly scripts for the package in question. It is either |
1203 | the same directory as for binaries, or a special one that can be |
1204 | mounted across different architectures, like /usr/share. Programs |
1205 | must be prepared to deal with ~name expansion. |
1206 | |
1207 | selecttype (selecttype.U): |
1208 | This variable holds the type used for the 2nd, 3rd, and 4th |
1209 | arguments to select. Usually, this is 'fd_set *', if HAS_FD_SET |
1210 | is defined, and 'int *' otherwise. This is only useful if you |
1211 | have select(), naturally. |
1212 | |
1213 | sh (sh.U): |
1214 | This variable contains the full pathname of the shell used |
1215 | on this system to execute Bourne shell scripts. Usually, this will be |
1216 | /bin/sh, though it's possible that some systems will have /bin/ksh, |
1217 | /bin/pdksh, /bin/ash, /bin/bash, or even something such as D:/bin/sh. |
1218 | This unit comes before Options.U, so you can't set sh with a -D |
1219 | option, though you can override this (and startsh) |
1220 | with -O -Dsh=/bin/whatever -Dstartsh=whatever |
1221 | |
1222 | shmattype (d_shmat.U): |
1223 | This symbol contains the type of pointer returned by shmat(). |

1225 | |
1226 | sig_name (sig_name.U): |
1227 | This variable holds the signal names, space separated. The leading |
1228 | SIG in signals name is removed. See sig_num. |
1229 | |
1230 | sig_num (sig_name.U): |
1231 | This variable holds the signal numbers, space separated. Those numbers |
1232 | correspond to the value of the signal listed in the same place within |
1233 | the sig_name list. |
1234 | |
1235 | signal_t (d_voidsig.U): |

1239 | This variable contains the eventual value of the SITEARCH symbol, |
1240 | which is the name of the private library for this package. It may |
1241 | have a ~ on the front. It is up to the makefile to eventually create |
1242 | this directory while performing installation (with ~ substitution). |
1243 | |
1244 | sitearchexp (sitearch.U): |
1245 | This variable is the ~name expanded version of sitearch, so that you |
1246 | may use it directly in Makefiles or shell scripts. |
1247 | |
1248 | sitelib (sitelib.U): |
1249 | This variable contains the eventual value of the SITELIB symbol, |
1250 | which is the name of the private library for this package. It may |

1252 | this directory while performing installation (with ~ substitution). |
1253 | |
1254 | sitelibexp (sitelib.U): |
1255 | This variable is the ~name expanded version of sitelib, so that you |

1259 | This variable defines sizetype to be something like size_t, |
1260 | unsigned long, or whatever type is used to declare length |
1261 | parameters for string functions. |
1262 | |
1263 | small (models.U): |
1264 | This variable contains a flag which will tell the C compiler and loader |
1265 | to produce a program running with a small memory model. It is up to |
1266 | the Makefile to use this. |
1267 | |
1268 | spitshell (spitshell.U): |
1269 | This variable contains the command necessary to spit out a runnable |
1270 | shell on this system. It is either cat or a grep -v for # comments. |
1271 | |
1272 | split (models.U): |
1273 | This variable contains a flag which will tell the C compiler and loader |
1274 | to produce a program that will run in separate I and D space, for those |
1275 | machines that support separation of instruction and data space. It is |
1276 | up to the Makefile to use this. |
1277 | |
1278 | ssizetype (ssizetype.U): |
1279 | This variable defines ssizetype to be something like ssize_t, |
1280 | long or int. It is used by functions that return a count |
1281 | of bytes or an error condition. It must be a signed type. |
1282 | We will pick a type such that sizeof(SSize_t) == sizeof(Size_t). |
1283 | |
1284 | startperl (startperl.U): |
1285 | This variable contains the string to put on the front of a perl |
1286 | script to make sure (hopefully) that it runs with perl and not some |
1287 | shell. Of course, that leading line must be followed by the classical |
1288 | perl idiom: |
1289 | eval 'exec perl -S $0 "$@"' |
1290 | if $running_under_some_shell; |
1291 | to guarantee perl startup should the shell execute the script. Note |
1292 | that this magic incatation is not understood by csh. |
1293 | |
1294 | startsh (startsh.U): |
1295 | This variable contains the string to put on the front of a shell |
1296 | script to make sure (hopefully) that it runs with sh and not some |

1306 | |
1307 | timetype (d_time.U): |
1308 | This variable holds the type returned by time(). It can be long, |
1309 | or time_t on BSD sites (in which case <sys/types.h> should be |
1310 | included). Anyway, the type Time_t should be used. |
1311 | |
1312 | uidtype (uidtype.U): |
1313 | This variable defines Uid_t to be something like uid_t, int, |
