1060 | the user is explicitely prompted for it. This variable should always |
1061 | be used in your makefiles for maximum portability. |
1062 | |
1063 | installprivlib (privlib.U): |
1064 | This variable is really the same as privlibexp but may differ on |
1065 | those systems using AFS. For extra portability, only this variable |
1066 | should be used in makefiles. |
1067 | |
1068 | intsize (intsize.U): |
1069 | This variable contains the value of the INTSIZE symbol, |
1070 | which indicates to the C program how many bytes there are |
1071 | in an integer. |
1072 | |
1073 | large (models.U): |
1074 | This variable contains a flag which will tell the C compiler and loader |
1075 | to produce a program running with a large memory model. It is up to |
1076 | the Makefile to use this. |
1077 | |
1078 | ld (dlsrc.U): |
1079 | This variable indicates the program to be used to link |
1080 | libraries for dynamic loading. On some systems, it is 'ld'. |

1084 | lddlflags (dlsrc.U): |
1085 | This variable contains any special flags that might need to be |
1086 | passed to $ld to create a shared library suitable for dynamic |

1089 | |
1090 | ldflags (ccflags.U): |
1091 | This variable contains any additional C loader flags desired by |
1092 | the user. It is up to the Makefile to use this. |

1098 | |
1099 | libperl (libperl.U): |
1100 | The perl executable is obtained by linking perlmain.c with |
1101 | libperl, any static extensions (usually just DynaLoader), |
1102 | and any other libraries needed on this system. libperl |
1103 | is usually libperl.a, but can also be libperl.so.xxx if |
1104 | the user wishes to build a perl executable with a shared |
1105 | library. |
1106 | |
1107 | libs (libs.U): |
1108 | This variable holds the additional libraries we want to use. |
1109 | It is up to the Makefile to deal with it. |

1125 | |
1126 | make (make.U): |
1127 | This variable sets the path to the 'make' command. It is |
1128 | here rather than in Loc.U so that users can override it |
1129 | with Configure -Dmake=pmake, or equivalent. |
1130 | |
1131 | make_set_make (make.U): |
1132 | Some versions of 'make' set the variable MAKE. Others do not. |
1133 | This variable contains the string to be included in Makefile.SH |
1134 | so that MAKE is set if needed, and not if not needed. |
1135 | Possible values are: |
1136 | make_set_make='#' # If your make program handles this for you, |
1137 | make_set_make=$make # if it doesn't. |
1138 | I used a comment character so that we can distinguish a |
1139 | 'set' value (from a previous config.sh or Configure -D option) |
1140 | from an uncomputed value. |
1141 | |
1142 | mallocobj (mallocsrc.U): |
1143 | This variable contains the name of the malloc.o that this package |
1144 | generates, if that malloc.o is preferred over the system malloc. |

1146 | Makefiles. See mallocsrc. |
1147 | |
1148 | mallocsrc (mallocsrc.U): |
1149 | This variable contains the name of the malloc.c that comes with |
1150 | the package, if that malloc.c is preferred over the system malloc. |
1151 | Otherwise the value is null. This variable is intended for generating |
1152 | Makefiles. |
1153 | |
1154 | malloctype (mallocsrc.U): |
1155 | This variable contains the kind of ptr returned by malloc and realloc. |
1156 | |
1157 | man1dir (man1dir.U): |
1158 | This variable contains the name of the directory in which manual |
1159 | source pages are to be put. It is the responsibility of the |
1160 | Makefile.SH to get the value of this into the proper command. |
1161 | You must be prepared to do the ~name expansion yourself. |
1162 | |
1163 | man1ext (man1dir.U): |
1164 | This variable contains the extension that the manual page should |
1165 | have: one of 'n', 'l', or '1'. The Makefile must supply the '.'. |

1173 | |
1174 | man3ext (man3dir.U): |
1175 | This variable contains the extension that the manual page should |
1176 | have: one of 'n', 'l', or '3'. The Makefile must supply the '.'. |

1181 | int, unsigned short, or whatever type is used to declare file |
1182 | modes for system calls. |
1183 | |
1184 | n (n.U): |
1185 | This variable contains the -n flag if that is what causes the echo |
1186 | command to suppress newline. Otherwise it is null. Correct usage is |
1187 | $echo $n "prompt for a question: $c". |
1188 | |
1189 | o_nonblock (nblock_io.U): |
1190 | This variable bears the symbol value to be used during open() or fcntl() |
1191 | to turn on non-blocking I/O for a file descriptor. If you wish to switch |
1192 | between blocking and non-blocking, you may try ioctl(FIOSNBIO) instead, |
1193 | but that is only supported by some devices. |
1194 | |
1195 | oldarchlib (oldarchlib.U): |
1196 | This variable holds the name of the directory in which perl5.000 |
1197 | and perl5.001 stored |
1198 | architecture-dependent public library files. |
1199 | |
1200 | oldarchlibexp (oldarchlib.U): |
1201 | This variable is the same as the oldarchlib variable, but is |
1202 | filename expanded at configuration time, for convenient use. |
1203 | |
1204 | optimize (ccflags.U): |
1205 | This variable contains any optimizer/debugger flag that should be used. |
1206 | It is up to the Makefile to use it. |
1207 | |
1208 | osname (Oldconfig.U): |
1209 | This variable contains the operating system name (e.g. sunos, |
1210 | solaris, hpux, etc.). It can be useful later on for setting |
1211 | defaults. Any spaces are replaced with underscores. It is set |
1212 | to a null string if we can't figure it out. |
1213 | |
1214 | pager (pager.U): |
1215 | This variable contains the name of the preferred pager on the system. |
1216 | Usual values are (the full pathnames of) more, less, pg, or cat. |
1217 | |
1218 | path_sep (Unix.U): |
1219 | This variable defines the character used to separate elements in |
1220 | the shell's PATH environment variable. On Unix, it is ':'. |
1221 | This is probably identical to Head.U's p_ variable and can |
1222 | probably be dropped. |
1223 | |
1224 | perladmin (perladmin.U): |
1225 | Electronic mail address of the perl5 administrator. |
1226 | |
7e1af8bc |

d7418ba7 |
1232 | prefix (prefix.U): |
1233 | This variable holds the name of the directory below which the |
1234 | user will install the package. Usually, this is /usr/local, and |
1235 | executables go in /usr/local/bin, library stuff in /usr/local/lib, |
1236 | man pages in /usr/local/man, etc. It is only used to set defaults |
1237 | for things in bin.U, mansrc.U, privlib.U, or scriptdir.U. |
1238 | |
1239 | privlib (privlib.U): |
1240 | This variable contains the eventual value of the PRIVLIB symbol, |
1241 | which is the name of the private library for this package. It may |
1242 | have a ~ on the front. It is up to the makefile to eventually create |
1243 | this directory while performing installation (with ~ substitution). |
1244 | |
1245 | privlibexp (privlib.U): |
1246 | This variable is the ~name expanded version of privlib, so that you |
1247 | may use it directly in Makefiles or shell scripts. |

1259 | This variable is set to the pathname of the ranlib program, if it is |
1260 | needed to generate random libraries. Set to ":" if ar can generate |
1261 | random libraries or if random libraries are not supported |
1262 | |
1263 | rd_nodata (nblock_io.U): |
1264 | This variable holds the return code from read() when no data is |
1265 | present. It should be -1, but some systems return 0 when O_NDELAY is |
1266 | used, which is a shame because you cannot make the difference between |
1267 | no data and an EOF.. Sigh! |
1268 | |
1269 | scriptdir (scriptdir.U): |
1270 | This variable holds the name of the directory in which the user wants |
1271 | to put publicly scripts for the package in question. It is either |
1272 | the same directory as for binaries, or a special one that can be |
1273 | mounted across different architectures, like /usr/share. Programs |
1274 | must be prepared to deal with ~name expansion. |
1275 | |
1276 | selecttype (selecttype.U): |
1277 | This variable holds the type used for the 2nd, 3rd, and 4th |
1278 | arguments to select. Usually, this is 'fd_set *', if HAS_FD_SET |
1279 | is defined, and 'int *' otherwise. This is only useful if you |
1280 | have select(), naturally. |
1281 | |
1282 | sh (sh.U): |
1283 | This variable contains the full pathname of the shell used |
1284 | on this system to execute Bourne shell scripts. Usually, this will be |
1285 | /bin/sh, though it's possible that some systems will have /bin/ksh, |
bb14ff96 |
1286 | /bin/pdksh, /bin/ash, /bin/bash, or even something such as |
1287 | D:/bin/sh.exe. |
d7418ba7 |
1288 | This unit comes before Options.U, so you can't set sh with a -D |
1289 | option, though you can override this (and startsh) |
1290 | with -O -Dsh=/bin/whatever -Dstartsh=whatever |
1291 | |
1292 | shmattype (d_shmat.U): |
1293 | This symbol contains the type of pointer returned by shmat(). |
1294 | It can be 'void *' or 'char *'. |

1296 | shortsize (intsize.U): |
1297 | This variable contains the value of the SHORTSIZE symbol, |
1298 | which indicates to the C program how many bytes there are |
1299 | in a short integer. |
1300 | |
c43cd16b |
1301 | shrpenv (libperl.U): |
1302 | If the user builds a shared libperl.so, then we need to tell the |
1303 | 'perl' executable where it will be able to find the installed libperl.so. |
1304 | One way to do this on some systems is to set the environment variable |
1305 | LD_RUN_PATH to the directory that will be the final location of the |
1306 | shared libperl.so. The makefile can use this with something like |
1307 | $shrpenv $(CC) -o perl perlmain.o $libperl $libs |
1308 | Typical values are |
1309 | shrpenv="env LD_RUN_PATH=$archlibexp/CORE" |
1310 | or |
1311 | shrpenv='' |
1312 | See the main perl Makefile.SH for actual working usage. |
1313 | Alternatively, we might be able to use a command line option such |
1314 | as -R $archlibexp/CORE (Solaris, NetBSD) or -Wl,-rpath |
1315 | $archlibexp/CORE (Linux). |
1316 | |
d7418ba7 |
1317 | sig_name (sig_name.U): |
1318 | This variable holds the signal names, space separated. The leading |
1319 | SIG in signals name is removed. See sig_num. |
1320 | |
1321 | sig_num (sig_name.U): |
1322 | This variable holds the signal numbers, space separated. Those numbers |
1323 | correspond to the value of the signal listed in the same place within |
1324 | the sig_name list. |
1325 | |
1326 | signal_t (d_voidsig.U): |
1327 | This variable holds the type of the signal handler (void or int). |
1328 | |
1329 | sitearch (sitearch.U): |
1330 | This variable contains the eventual value of the SITEARCH symbol, |
1331 | which is the name of the private library for this package. It may |
1332 | have a ~ on the front. It is up to the makefile to eventually create |
1333 | this directory while performing installation (with ~ substitution). |
1334 | |
1335 | sitearchexp (sitearch.U): |
1336 | This variable is the ~name expanded version of sitearch, so that you |
1337 | may use it directly in Makefiles or shell scripts. |
1338 | |
1339 | sitelib (sitelib.U): |
1340 | This variable contains the eventual value of the SITELIB symbol, |
1341 | which is the name of the private library for this package. It may |
1342 | have a ~ on the front. It is up to the makefile to eventually create |
1343 | this directory while performing installation (with ~ substitution). |
1344 | |
1345 | sitelibexp (sitelib.U): |
1346 | This variable is the ~name expanded version of sitelib, so that you |

1350 | This variable defines sizetype to be something like size_t, |
1351 | unsigned long, or whatever type is used to declare length |
1352 | parameters for string functions. |
1353 | |
1354 | small (models.U): |
1355 | This variable contains a flag which will tell the C compiler and loader |
1356 | to produce a program running with a small memory model. It is up to |
1357 | the Makefile to use this. |
1358 | |
1359 | spitshell (spitshell.U): |
1360 | This variable contains the command necessary to spit out a runnable |
1361 | shell on this system. It is either cat or a grep -v for # comments. |
1362 | |
1363 | split (models.U): |
1364 | This variable contains a flag which will tell the C compiler and loader |
1365 | to produce a program that will run in separate I and D space, for those |
1366 | machines that support separation of instruction and data space. It is |
1367 | up to the Makefile to use this. |
1368 | |
1369 | ssizetype (ssizetype.U): |
1370 | This variable defines ssizetype to be something like ssize_t, |
1371 | long or int. It is used by functions that return a count |
1372 | of bytes or an error condition. It must be a signed type. |
1373 | We will pick a type such that sizeof(SSize_t) == sizeof(Size_t). |
1374 | |
1375 | startperl (startperl.U): |
1376 | This variable contains the string to put on the front of a perl |
1377 | script to make sure (hopefully) that it runs with perl and not some |
1378 | shell. Of course, that leading line must be followed by the classical |
1379 | perl idiom: |
5f05dabc |
1380 | eval 'exec /usr/bin/perl -S $0 ${1+"$@"}' |
d7418ba7 |
1381 | if $running_under_some_shell; |
1382 | to guarantee perl startup should the shell execute the script. Note |
1383 | that this magic incatation is not understood by csh. |
1384 | |
