| \`configure' configures libpng 1.6.38.git to adapt to many kinds of systems. |
| |
| Usage: $0 [OPTION]... [VAR=VALUE]... |
| |
| To assign environment variables (e.g., CC, CFLAGS...), specify them as |
| VAR=VALUE. See below for descriptions of some of the useful variables. |
| |
| Defaults for the options are specified in brackets. |
| |
| Configuration: |
| -h, --help display this help and exit |
| --help=short display options specific to this package |
| --help=recursive display the short help of all the included packages |
| -V, --version display version information and exit |
| -q, --quiet, --silent do not print \`checking ...' messages |
| --cache-file=FILE cache test results in FILE [disabled] |
| -C, --config-cache alias for \`--cache-file=config.cache' |
| -n, --no-create do not create output files |
| --srcdir=DIR find the sources in DIR [configure dir or \`..'] |
| |
| Installation directories: |
| --prefix=PREFIX install architecture-independent files in PREFIX |
| [$ac_default_prefix] |
| --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX |
| [PREFIX] |
| |
| By default, \`make install' will install all the files in |
| \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify |
| an installation prefix other than \`$ac_default_prefix' using \`--prefix', |
| for instance \`--prefix=\$HOME'. |
| |
| For better control, use the options below. |
| |
| Fine tuning of the installation directories: |
| --bindir=DIR user executables [EPREFIX/bin] |
| --sbindir=DIR system admin executables [EPREFIX/sbin] |
| --libexecdir=DIR program executables [EPREFIX/libexec] |
| --sysconfdir=DIR read-only single-machine data [PREFIX/etc] |
| --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com] |
| --localstatedir=DIR modifiable single-machine data [PREFIX/var] |
| --runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run] |
| --libdir=DIR object code libraries [EPREFIX/lib] |
| --includedir=DIR C header files [PREFIX/include] |
| --oldincludedir=DIR C header files for non-gcc [/usr/include] |
| --datarootdir=DIR read-only arch.-independent data root [PREFIX/share] |
| --datadir=DIR read-only architecture-independent data [DATAROOTDIR] |
| --infodir=DIR info documentation [DATAROOTDIR/info] |

| Optional Features: |
| --disable-option-checking ignore unrecognized --enable/--with options |
| --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no) |
| --enable-FEATURE[=ARG] include FEATURE [ARG=yes] |
| --enable-silent-rules less verbose build output (undo: "make V=1") |
| --disable-silent-rules verbose build output (undo: "make V=0") |
| --enable-maintainer-mode |
| enable make rules and dependencies not useful (and |
| sometimes confusing) to the casual installer |
| --enable-dependency-tracking |
| do not reject slow dependency extractors |
| --disable-dependency-tracking |
| speeds up one-time build |
| --enable-shared[=PKGS] build shared libraries [default=yes] |
| --enable-static[=PKGS] build static libraries [default=yes] |
| --enable-fast-install[=PKGS] |
| optimize for fast installation [default=yes] |
| --disable-libtool-lock avoid locking (might break parallel builds) |
| --enable-werror[=OPT] Pass -Werror or the given argument to the compiler |
| if it is supported |
| --enable-unversioned-links |
| Installed libpng header files are placed in a |
| versioned subdirectory and installed libpng library |
| (including DLL) files are versioned. If this option |
| is enabled unversioned links will be created |
| pointing to the corresponding installed files. If |
| you use libpng.pc or libpng-config for all builds |
| you do not need these links, but if you compile |
| programs directly they will typically #include |
| <png.h> and link with -lpng; in that case you need |
| the links. The links can be installed manually using |
| 'make install-header-links' and 'make |
| install-library-links' and can be removed using the |
| corresponding uninstall- targets. If you do enable |
| this option every libpng 'make install' will |
| recreate the links to point to the just installed |
| version of libpng. The default is to create the |
| links; use --disable-unversioned-links to change |
| this |
| --enable-unversioned-libpng-pc |
| Install the configuration file 'libpng.pc' as a link |
| to the versioned version. This is done by default - |
| use --disable-unversioned-libpng-pc to change this. |
| --enable-unversioned-libpng-config |
| Install the configuration file 'libpng-config' as a |
| link to the versioned version. This is done by |
| default - use --disable-unversioned-libpng-config to |
| change this. |
| --enable-hardware-optimizations |
| Enable hardware optimizations: =no/off, yes/on: |
| --enable-arm-neon Enable ARM NEON optimizations: =no/off, check, api, |
| yes/on: no/off: disable the optimizations; check: |
| use internal checking code (deprecated and poorly |
| supported); api: disable by default, enable by a |
| call to png_set_option; yes/on: turn on |
| unconditionally. If not specified: determined by the |
| compiler. |
| --enable-mips-msa Enable MIPS MSA optimizations: =no/off, check, api, |
| yes/on: no/off: disable the optimizations; check: |
| use internal checking code (deprecated and poorly |
| supported); api: disable by default, enable by a |
| call to png_set_option; yes/on: turn on |
| unconditionally. If not specified: determined by the |
| compiler. |
| --enable-intel-sse Enable Intel SSE optimizations: =no/off, yes/on: |
| no/off: disable the optimizations; yes/on: enable |
| the optimizations. If not specified: determined by |
| the compiler. |
| --enable-powerpc-vsx Enable POWERPC VSX optimizations: =no/off, check, |
| api, yes/on: no/off: disable the optimizations; |
| check: use internal checking code api: disable by |
| default, enable by a call to png_set_option yes/on: |
| turn on unconditionally. If not specified: |
| determined by the compiler. |
| |
| Optional Packages: |
| --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] |
| --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no) |
| --with-gnu-ld assume the C compiler uses GNU ld [default=no] |
| --with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use |
| both] |
| --with-aix-soname=aix|svr4|both |
| shared library versioning (aka "SONAME") variant to |
| provide on AIX, [default=aix]. |
| --with-sysroot[=DIR] Search for dependent libraries within DIR (or the |
| compiler's sysroot if not specified). |
| --with-zlib-prefix prefix that may have been used in installed zlib |
| --with-pkgconfigdir Use the specified pkgconfig dir (default is |
| libdir/pkgconfig) |
| --with-binconfigs Generate shell libpng-config scripts as well as |
| pkg-config data [default=yes] |
| --with-libpng-prefix prefix libpng exported function (API) names with the |
| given value |
| |
| Some influential environment variables: |
| CC C compiler command |
| CFLAGS C compiler flags |
| LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a |
| nonstandard directory <lib dir> |
| LIBS libraries to pass to the linker, e.g. -l<library> |
| CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if |
| you have headers in a nonstandard directory <include dir> |
| CCAS assembler compiler command (defaults to CC) |
| CCASFLAGS assembler compiler flags (defaults to CFLAGS) |
| CPP C preprocessor |
| LT_SYS_LIBRARY_PATH |
| User-defined run-time library search path. |
| PNG_COPTS additional flags for the C compiler, use this for options that |
| would cause configure itself to fail |
| |
| Use these variables to override the choices made by `configure' or to help |
| it to find libraries and programs with nonstandard names/locations. |
