一、查看编译configure 能支持的选项：./configure --help
root@nicholas-virtual-machine:/home/nicholas/linux_libnfc-nci# ./configure --help `configure' configures libnfc_nci_linux 1.0 to adapt to many kinds of systems.
Usage: ./configure [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 [/usr/local] --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX [PREFIX]
By default, `make install' will install all the files in `/usr/local/bin', `/usr/local/lib' etc. You can specify an installation prefix other than `/usr/local' 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] --localedir=DIR locale-dependent data [DATAROOTDIR/locale] --mandir=DIR man documentation [DATAROOTDIR/man] --docdir=DIR documentation root [DATAROOTDIR/doc/libnfc_nci_linux] --htmldir=DIR html documentation [DOCDIR] --dvidir=DIR dvi documentation [DOCDIR] --pdfdir=DIR pdf documentation [DOCDIR] --psdir=DIR ps documentation [DOCDIR]
Program names: --program-prefix=PREFIX prepend PREFIX to installed program names --program-suffix=SUFFIX append SUFFIX to installed program names --program-transform-name=PROGRAM run sed PROGRAM on installed program names
System types: --build=BUILD configure for building on BUILD [guessed] --host=HOST cross-compile to build programs to run on HOST [BUILD]
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-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-debug whether to include debug symbols (default is no) --enable-llcp1_3 enable LLCP1.3 (secured P2P) --enable-abend set TML to ABEND --enable-lpcusbsio set TML to LPCUSBSIO --enable-i2c set TML to I2C --enable-alt set TML to ALT
Optional Packages: --with-PACKAGE[=ARG] use PACKAGE [ARG=yes] --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=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-gnu-ld assume the C compiler uses GNU ld [default=no] --with-sysroot[=DIR] Search for dependent libraries within DIR (or the compiler's sysroot if not specified).
Some influential environment variables: CXX C++ compiler command CXXFLAGS 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> CC C compiler command CFLAGS C compiler flags LT_SYS_LIBRARY_PATH User-defined run-time library search path. CPP C preprocessor CXXCPP C++ preprocessor openssldir openssl installation path PKG_CONFIG path to pkg-config utility PKG_CONFIG_PATH directories to add to pkg-config's search path PKG_CONFIG_LIBDIR path overriding pkg-config's built-in search path UDEV_CFLAGS C compiler flags for UDEV, overriding pkg-config UDEV_LIBS linker flags for UDEV, overriding pkg-config
Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.
