DESCRIPTION

       icu-config simplifies the task of building and linking against ICU as compared to manually
       configuring user makefiles or equivalent.  Because icu-config is an executable script,  it
       also  solves the problem of locating the ICU libraries and headers, by allowing the system
       PATH to locate it.

EXAMPLES

       icu-config can be used without a makefile.  The  command  line  below  is  sufficient  for
       building     a     single-file     c++     program     against    ICU.    (For    example,
       icu/source/samples/props/props.cpp)

              `icu-config --cxx --cxxflags --cppflags --ldflags` -o props props.cpp

       More commonly, icu-config will be called from within  a  makefile,  and  used  to  set  up
       variables. The following example also builds the props example.

              CC=$(shell icu-config --cc)

              CXX=$(shell icu-config --cxx)

              CPPFLAGS=$(shell icu-config --cppflags)

              CXXFLAGS=$(shell icu-config --cxxflags)

              LDFLAGS =$(shell icu-config --ldflags)

              all: props

              props.o: props.cpp

       make(1) will automatically use the above variables.

OPTIONS

       --bindir
              Prints  the  binary (executable) directory path. Normally equivalent to 'bin'.  ICU
              user-executable applications and scripts are found here.

       --cc   Print the C compiler used.  Equivalent to the $(CC) Makefile variable.

       --cflags
              Print the C compiler flags. Equivalent to the $(CFLAGS)  Makefile  variable.   Does
              NOT  include  preprocessor  directives  such  as  include  path or defined symbols.
              Examples include debugging (-g) and optimization flags

       --cppflags
              Print the C preprocessor flags. Equivalent to the  $(CPPFLAGS)  Makefile  variable.
              Examples are -I include paths  and -D define directives.

       --cppflags-searchpath
              Print the C preprocessor flags, as above but only -I search paths.

       --cxx  Print the C++ compiler. Equivalent to the $(CXX) Makefile variable.

       --cxxflags
              Print the C++ compiler flags. Equivalent to the $(CXXFLAGS) Makefile variable.

       --detect-prefix
              If  ICU  has  been moved from its installed location, prepending this flag to other
              icu-config calls will attempt to locate ICU relative to where the icu-config script
              has  been  located. Can be used as a last-chance effort if the ICU install has been
              damaged.

       --exec-prefix
              Print the prefix used for executable program directories (such as bin, sbin,  etc).
              Normally the same as the prefix.

       --exists
              Script  will  return  with a successful (0) status if ICU seems to be installed and
              located correctly, otherwise an error message and nonzero status will be displayed.

       --help, -?,--usage
              Print a help and usage message.

       --icudata
              Print the shortname of the ICU data file. This does not include any suffix such  as
              .dat,  .dll, .so, .lib, .a, etc nor does it include prefixes such as 'lib'.  It may
              be in the form icudt21b

       --icudata-install-dir
              Print the directory where ICU packaged data  should  be  installed.    Can  use  as
              pkgdata(1)'s --install option.

       --icudata-mode
              Print the default ICU pkgdata mode, such as dll or common.  Can use as pkgdata(1)'s
              --mode option.

       --icudatadir
              Print the path to packaged archive data.  (should be where $ICU_DATA or  equivalent
              default path points.)  Will NOT point to the libdir.

       --invoke
              If  ICU  is  not installed in a location where the operating system will locate its
              shared libraries, this option will print out commands so as to set the  appropriate
              environment  variables to load ICU's shared libraries. For example, on many systems
              a variable named LD_LIBRARY_PATH or equivalent must be set.

       --invoke=prog
              Same as the --invoke option, except includes options for invoking a  program  named
              prog.   If  prog is the name of an ICU tool, such as genrb(1), then icu-config will
              also include the full path to that tool.

       --ldflags
              Print any flags which should be passed to the linker.  These  may  include  -L  for
              library  search  paths, and -l for including ICU libraries. By default, this option
              will attempt to link in the "common" (libicuuc) and "i18n" (libicui18n)  libraries,
              as  well  as  the  data  library.  If additional libraries are required, any of the
              following two flags may  be  added  in  conjunction  with  this  one,  for  example
              "--ldflags  --ldflags-icuio"  if  the  icuio library is required in addition to the
              standard ICU libraries.  Equivalent to the $(LDFLAGS) Makefile variable.

       --ldflags-layout
              Prints the link option for the ICU layout library.

       --ldflags-icuio
              Prints the link option to add the ICU I/O package

       --ldflags-libsonly
              Similar to --ldflags but only includes the -l options.

       --ldflags-searchpath
              Similar to --ldflags but only includes the -L search path options.

       --ldflags-system
              Similar to --ldflags but only includes system libraries (such as pthreads) --mandir
              Prints the location of the installed ICU man pages. Normally (man)

       --prefix
              Prints the prefix (base directory) under which the installed ICU resides.

       --prefix=prefix
              Sets  the  ICU  prefix to prefix for the remainder of this command line.  Does test
              whether the new prefix is valid.

       --sbindir
              Prints the location of ICU system binaries, normally (sbin)

       --shared-datadir
              Prints the location of ICU shared data, normally (share)

       --sysconfdir
              Prints the location of ICU system configuration data, normally (etc)

       --unicode-version
              Prints the Version of the Unicode Standard which the current ICU uses.

       --version
              Prints the current version of ICU.

       --incfile
              Prints the 'Makefile.inc' path, suitable for use with pkgdata(1)'s -O option.
