974 | |
975 | i_termio (i_termio.U): |
976 | This variable conditionally defines the I_TERMIO symbol, which |
977 | indicates to the C program that it should include <termio.h> rather |

1011 | This variable conditionally defines the I_VFORK symbol, and indicates |
1012 | whether a C program should include vfork.h. |
1013 | |
1014 | installbin (bin.U): |
1015 | This variable is the same as binexp unless AFS is running in which case |
1016 | the user is explicitely prompted for it. This variable should always |
1017 | be used in your makefiles for maximum portability. |
1018 | |
1019 | installprivlib (privlib.U): |
1020 | This variable is really the same as privlibexp but may differ on |
1021 | those systems using AFS. For extra portability, only this variable |
1022 | should be used in makefiles. |
1023 | |
1024 | intsize (intsize.U): |
1025 | This variable contains the value of the INTSIZE symbol, |
1026 | which indicates to the C program how many bytes there are |
1027 | in an integer. |
1028 | |
1029 | large (models.U): |
1030 | This variable contains a flag which will tell the C compiler and loader |
1031 | to produce a program running with a large memory model. It is up to |
1032 | the Makefile to use this. |
1033 | |
1034 | ld (dlsrc.U): |
1035 | This variable indicates the program to be used to link |
1036 | libraries for dynamic loading. On some systems, it is 'ld'. |
1037 | On ELF systems, it should be $cc. Mostly, we'll try to respect |
1038 | the hint file setting. |
1039 | |
1040 | lddlflags (dlsrc.U): |
1041 | This variable contains any special flags that might need to be |
1042 | passed to $ld to create a shared library suitable for dynamic |
1043 | loading. It is up to the makefile to use it. For hpux, it |
1044 | should be -b. For sunos 4.1, it is empty. |
1045 | |
1046 | ldflags (ccflags.U): |
1047 | This variable contains any additional C loader flags desired by |
1048 | the user. It is up to the Makefile to use this. |
1049 | |
1050 | lib_ext (Unix.U): |
1051 | This variable defines the extension used for ordinary libraries. |
1052 | For unix, it is '.a'. The '.' is included. Other possible |
1053 | values include '.lib'. |
1054 | |
1055 | libperl (libperl.U): |
1056 | The perl executable is obtained by linking perlmain.c with |
1057 | libperl, any static extensions (usually just DynaLoader), |
1058 | and any other libraries needed on this system. libperl |
1059 | is usually libperl.a, but can also be libperl.so.xxx if |
1060 | the user wishes to build a perl executable with a shared |
1061 | library. |
1062 | |
1063 | libs (libs.U): |
1064 | This variable holds the additional libraries we want to use. |

1070 | in the Makefile. It is either 'ln -s' or 'ln' |
1071 | |
1072 | lseektype (lseektype.U): |
1073 | This variable defines lseektype to be something like off_t, long, |
1074 | or whatever type is used to declare lseek offset's type in the |
1075 | kernel (which also appears to be lseek's return type). |
1076 | |
1077 | make (make.U): |
1078 | This variable sets the path to the 'make' command. It is |
1079 | here rather than in Loc.U so that users can override it |
1080 | with Configure -Dmake=pmake, or equivalent. |
1081 | |
1082 | make_set_make (make.U): |
1083 | Some versions of 'make' set the variable MAKE. Others do not. |
1084 | This variable contains the string to be included in Makefile.SH |
1085 | so that MAKE is set if needed, and not if not needed. |
1086 | Possible values are: |
1087 | make_set_make='#' # If your make program handles this for you, |
1088 | make_set_make=$make # if it doesn't. |
1089 | I used a comment character so that we can distinguish a |
1090 | 'set' value (from a previous config.sh or Configure -D option) |
1091 | from an uncomputed value. |
1092 | |
1093 | mallocobj (mallocsrc.U): |
1094 | This variable contains the name of the malloc.o that this package |
1095 | generates, if that malloc.o is preferred over the system malloc. |
1096 | Otherwise the value is null. This variable is intended for generating |
1097 | Makefiles. See mallocsrc. |
1098 | |
1099 | mallocsrc (mallocsrc.U): |
1100 | This variable contains the name of the malloc.c that comes with |
1101 | the package, if that malloc.c is preferred over the system malloc. |

1103 | Makefiles. |
1104 | |
1105 | malloctype (mallocsrc.U): |
1106 | This variable contains the kind of ptr returned by malloc and realloc. |
1107 | |
1108 | man1dir (man1dir.U): |
1109 | This variable contains the name of the directory in which manual |
1110 | source pages are to be put. It is the responsibility of the |
1111 | Makefile.SH to get the value of this into the proper command. |
1112 | You must be prepared to do the ~name expansion yourself. |
1113 | |
1114 | man1ext (man1dir.U): |
1115 | This variable contains the extension that the manual page should |
1116 | have: one of 'n', 'l', or '1'. The Makefile must supply the '.'. |

1118 | |
1119 | man3dir (man3dir.U): |
1120 | This variable contains the name of the directory in which manual |
1121 | source pages are to be put. It is the responsibility of the |

1124 | |
1125 | man3ext (man3dir.U): |
1126 | This variable contains the extension that the manual page should |
1127 | have: one of 'n', 'l', or '3'. The Makefile must supply the '.'. |

1131 | This variable defines modetype to be something like mode_t, |
1132 | int, unsigned short, or whatever type is used to declare file |
1133 | modes for system calls. |
1134 | |
1135 | n (n.U): |
1136 | This variable contains the -n flag if that is what causes the echo |
1137 | command to suppress newline. Otherwise it is null. Correct usage is |
1138 | $echo $n "prompt for a question: $c". |
1139 | |
1140 | o_nonblock (nblock_io.U): |
1141 | This variable bears the symbol value to be used during open() or fcntl() |
1142 | to turn on non-blocking I/O for a file descriptor. If you wish to switch |
1143 | between blocking and non-blocking, you may try ioctl(FIOSNBIO) instead, |
1144 | but that is only supported by some devices. |
1145 | |
1146 | oldarchlib (oldarchlib.U): |
1147 | This variable holds the name of the directory in which perl5.000 |
1148 | and perl5.001 stored |
1149 | architecture-dependent public library files. |
1150 | |
1151 | oldarchlibexp (oldarchlib.U): |
1152 | This variable is the same as the oldarchlib variable, but is |
1153 | filename expanded at configuration time, for convenient use. |
1154 | |
1155 | optimize (ccflags.U): |
1156 | This variable contains any optimizer/debugger flag that should be used. |
1157 | It is up to the Makefile to use it. |
1158 | |
1159 | osname (Oldconfig.U): |
1160 | This variable contains the operating system name (e.g. sunos, |
1161 | solaris, hpux, etc.). It can be useful later on for setting |
1162 | defaults. Any spaces are replaced with underscores. It is set |
1163 | to a null string if we can't figure it out. |
1164 | |
1165 | pager (pager.U): |
1166 | This variable contains the name of the preferred pager on the system. |
1167 | Usual values are (the full pathnames of) more, less, pg, or cat. |
1168 | |
1169 | path_sep (Unix.U): |
1170 | This variable defines the character used to separate elements in |
1171 | the shell's PATH environment variable. On Unix, it is ':'. |
1172 | This is probably identical to Head.U's p_ variable and can |
1173 | probably be dropped. |
1174 | |
1175 | perladmin (perladmin.U): |
1176 | Electronic mail address of the perl5 administrator. |
1177 | |
1178 | prefix (prefix.U): |
1179 | This variable holds the name of the directory below which the |
1180 | user will install the package. Usually, this is /usr/local, and |
1181 | executables go in /usr/local/bin, library stuff in /usr/local/lib, |
1182 | man pages in /usr/local/man, etc. It is only used to set defaults |
1183 | for things in bin.U, mansrc.U, privlib.U, or scriptdir.U. |
1184 | |
1185 | privlib (privlib.U): |
1186 | This variable contains the eventual value of the PRIVLIB symbol, |
1187 | which is the name of the private library for this package. It may |
1188 | have a ~ on the front. It is up to the makefile to eventually create |
1189 | this directory while performing installation (with ~ substitution). |
1190 | |
1191 | privlibexp (privlib.U): |
1192 | This variable is the ~name expanded version of privlib, so that you |
1193 | may use it directly in Makefiles or shell scripts. |
1194 | |
1195 | prototype (prototype.U): |
1196 | This variable holds the eventual value of CAN_PROTOTYPE, which |

1198 | |
1199 | randbits (randbits.U): |
1200 | This variable contains the eventual value of the RANDBITS symbol, |
1201 | which indicates to the C program how many bits of random number |
1202 | the rand() function produces. |
1203 | |
1204 | ranlib (orderlib.U): |
1205 | This variable is set to the pathname of the ranlib program, if it is |
1206 | needed to generate random libraries. Set to ":" if ar can generate |
1207 | random libraries or if random libraries are not supported |
1208 | |
1209 | rd_nodata (nblock_io.U): |
1210 | This variable holds the return code from read() when no data is |
1211 | present. It should be -1, but some systems return 0 when O_NDELAY is |
1212 | used, which is a shame because you cannot make the difference between |
1213 | no data and an EOF.. Sigh! |
1214 | |
1215 | scriptdir (scriptdir.U): |
1216 | This variable holds the name of the directory in which the user wants |
1217 | to put publicly scripts for the package in question. It is either |
1218 | the same directory as for binaries, or a special one that can be |
1219 | mounted across different architectures, like /usr/share. Programs |
1220 | must be prepared to deal with ~name expansion. |
1221 | |
1222 | selecttype (selecttype.U): |
1223 | This variable holds the type used for the 2nd, 3rd, and 4th |
1224 | arguments to select. Usually, this is 'fd_set *', if HAS_FD_SET |
1225 | is defined, and 'int *' otherwise. This is only useful if you |
1226 | have select(), naturally. |
1227 | |
1228 | sh (sh.U): |
1229 | This variable contains the full pathname of the shell used |
1230 | on this system to execute Bourne shell scripts. Usually, this will be |
1231 | /bin/sh, though it's possible that some systems will have /bin/ksh, |
bb14ff96 |
1232 | /bin/pdksh, /bin/ash, /bin/bash, or even something such as |
1233 | D:/bin/sh.exe. |
d7418ba7 |
1234 | This unit comes before Options.U, so you can't set sh with a -D |
1235 | option, though you can override this (and startsh) |
1236 | with -O -Dsh=/bin/whatever -Dstartsh=whatever |
1237 | |
1238 | shmattype (d_shmat.U): |
1239 | This symbol contains the type of pointer returned by shmat(). |
1240 | It can be 'void *' or 'char *'. |
1241 | |
c43cd16b |
1242 | shrpenv (libperl.U): |
1243 | If the user builds a shared libperl.so, then we need to tell the |
1244 | 'perl' executable where it will be able to find the installed libperl.so. |
1245 | One way to do this on some systems is to set the environment variable |
1246 | LD_RUN_PATH to the directory that will be the final location of the |
1247 | shared libperl.so. The makefile can use this with something like |
1248 | $shrpenv $(CC) -o perl perlmain.o $libperl $libs |
1249 | Typical values are |
1250 | shrpenv="env LD_RUN_PATH=$archlibexp/CORE" |
1251 | or |
1252 | shrpenv='' |
1253 | See the main perl Makefile.SH for actual working usage. |
1254 | Alternatively, we might be able to use a command line option such |
1255 | as -R $archlibexp/CORE (Solaris, NetBSD) or -Wl,-rpath |
1256 | $archlibexp/CORE (Linux). |
1257 | |
d7418ba7 |
1258 | sig_name (sig_name.U): |
1259 | This variable holds the signal names, space separated. The leading |
1260 | SIG in signals name is removed. See sig_num. |
1261 | |
1262 | sig_num (sig_name.U): |
1263 | This variable holds the signal numbers, space separated. Those numbers |
1264 | correspond to the value of the signal listed in the same place within |
1265 | the sig_name list. |
1266 | |
1267 | signal_t (d_voidsig.U): |
1268 | This variable holds the type of the signal handler (void or int). |
1269 | |
1270 | sitearch (sitearch.U): |
1271 | This variable contains the eventual value of the SITEARCH symbol, |
1272 | which is the name of the private library for this package. It may |
1273 | have a ~ on the front. It is up to the makefile to eventually create |
1274 | this directory while performing installation (with ~ substitution). |
1275 | |
1276 | sitearchexp (sitearch.U): |
1277 | This variable is the ~name expanded version of sitearch, so that you |
1278 | may use it directly in Makefiles or shell scripts. |
1279 | |
1280 | sitelib (sitelib.U): |
1281 | This variable contains the eventual value of the SITELIB symbol, |
1282 | which is the name of the private library for this package. It may |
1283 | have a ~ on the front. It is up to the makefile to eventually create |
1284 | this directory while performing installation (with ~ substitution). |
1285 | |
1286 | sitelibexp (sitelib.U): |
1287 | This variable is the ~name expanded version of sitelib, so that you |
1288 | may use it directly in Makefiles or shell scripts. |
1289 | |
1290 | sizetype (sizetype.U): |
1291 | This variable defines sizetype to be something like size_t, |
1292 | unsigned long, or whatever type is used to declare length |
1293 | parameters for string functions. |
1294 | |
1295 | small (models.U): |
1296 | This variable contains a flag which will tell the C compiler and loader |
1297 | to produce a program running with a small memory model. It is up to |
1298 | the Makefile to use this. |
1299 | |
1300 | spitshell (spitshell.U): |
1301 | This variable contains the command necessary to spit out a runnable |
1302 | shell on this system. It is either cat or a grep -v for # comments. |
1303 | |
1304 | split (models.U): |
1305 | This variable contains a flag which will tell the C compiler and loader |
1306 | to produce a program that will run in separate I and D space, for those |
1307 | machines that support separation of instruction and data space. It is |
1308 | up to the Makefile to use this. |
1309 | |
1310 | ssizetype (ssizetype.U): |
1311 | This variable defines ssizetype to be something like ssize_t, |
1312 | long or int. It is used by functions that return a count |
1313 | of bytes or an error condition. It must be a signed type. |
1314 | We will pick a type such that sizeof(SSize_t) == sizeof(Size_t). |
1315 | |
1316 | startperl (startperl.U): |
1317 | This variable contains the string to put on the front of a perl |
1318 | script to make sure (hopefully) that it runs with perl and not some |
1319 | shell. Of course, that leading line must be followed by the classical |
1320 | perl idiom: |
1321 | eval 'exec perl -S $0 "$@"' |
1322 | if $running_under_some_shell; |
1323 | to guarantee perl startup should the shell execute the script. Note |
1324 | that this magic incatation is not understood by csh. |
1325 | |
1326 | startsh (startsh.U): |
1327 | This variable contains the string to put on the front of a shell |
1328 | script to make sure (hopefully) that it runs with sh and not some |

1340 | This variable holds the type returned by time(). It can be long, |
1341 | or time_t on BSD sites (in which case <sys/types.h> should be |
1342 | included). Anyway, the type Time_t should be used. |
1343 | |
1344 | uidtype (uidtype.U): |
1345 | This variable defines Uid_t to be something like uid_t, int, |
1346 | ushort, or whatever type is used to declare user ids in the kernel. |
1347 | |

1350 | and indicates that the PerlIO abstraction should be |
1351 | used throughout. |
1352 | |
1353 | useshrplib (libperl.U): |
1354 | This variable is set to 'yes' if the user wishes |

1358 | This variable contains the eventual value of the VOIDFLAGS symbol, |
1359 | which indicates how much support of the void type is given by this |
1360 | compiler. See VOIDFLAGS for more info. |
1361 | |
