1290 \`configure' configures libpng (TeX Live) 1.6.28 to adapt to many kinds of systems.
1291
1292 Usage: $0 [OPTION]... [VAR=VALUE]...
1293
1294 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1295 VAR=VALUE. See below for descriptions of some of the useful variables.
1296
1297 Defaults for the options are specified in brackets.
1298
1299 Configuration:
1300 -h, --help display this help and exit
1301 --help=short display options specific to this package
1302 --help=recursive display the short help of all the included packages
1303 -V, --version display version information and exit
1304 -q, --quiet, --silent do not print \`checking ...' messages
1305 --cache-file=FILE cache test results in FILE [disabled]
1306 -C, --config-cache alias for \`--cache-file=config.cache'
1307 -n, --no-create do not create output files
1308 --srcdir=DIR find the sources in DIR [configure dir or \`..']
1309
1310 Installation directories:
1311 --prefix=PREFIX install architecture-independent files in PREFIX
1312 [$ac_default_prefix]
1313 --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
1314 [PREFIX]
1315
1316 By default, \`make install' will install all the files in
1317 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
1318 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1319 for instance \`--prefix=\$HOME'.
1320
1321 For better control, use the options below.
1322
1323 Fine tuning of the installation directories:
1324 --bindir=DIR user executables [EPREFIX/bin]
1325 --sbindir=DIR system admin executables [EPREFIX/sbin]
1326 --libexecdir=DIR program executables [EPREFIX/libexec]

1361 Optional Features:
1362 --disable-option-checking ignore unrecognized --enable/--with options
1363 --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
1364 --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
1365 --enable-silent-rules less verbose build output (undo: "make V=1")
1366 --disable-silent-rules verbose build output (undo: "make V=0")
1367 --enable-maintainer-mode
1368 enable make rules and dependencies not useful (and
1369 sometimes confusing) to the casual installer
1370 --enable-dependency-tracking
1371 do not reject slow dependency extractors
1372 --disable-dependency-tracking
1373 speeds up one-time build
1374 --enable-compiler-warnings=[no|min|yes|max|all]
1375 Turn on compiler warnings [default: yes if
1376 maintainer-mode, min otherwise]
1377
1378 Optional Packages:
1379 --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
1380 --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
1381 --with-system-zlib use installed zlib headers and library
1382 --with-zlib-includes=DIR
1383 zlib headers installed in DIR
1384 --with-zlib-libdir=DIR zlib library installed in DIR
1385
1386 Some influential environment variables:
1387 CC C compiler command
1388 CFLAGS C compiler flags
1389 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1390 nonstandard directory <lib dir>
1391 LIBS libraries to pass to the linker, e.g. -l<library>
1392 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1393 you have headers in a nonstandard directory <include dir>
1394 CPP C preprocessor
1395
1396 Use these variables to override the choices made by `configure' or to help
1397 it to find libraries and programs with nonstandard names/locations.
