Configuration utility.

Usage:

  configure [options]

Available options:

  --prefix=<dir>        base install path (/usr/local/)
  --bindir=<dir>        install path for executables (PREFIX/bin)
  --libdir=<dir>        install path for libraries (PREFIX/lib)
  --includedir=<dir>    install path for headers (PREFIX/include)

  --target=<target>     target platform (cross-compiling)

  --help                print this help message and exit

  --with-stlport=<dir>  use STLport in catalog <dir>
  --without-stlport     compile without STLport
  --with-boost=<dir>    use boost headers in catalog <dir>
  --with-system-boost   use boost installed on this system
  --with-msvc=<dir>     use MS VC from this catalog
  --with-mssdk=<dir>    use MS SDK from this catalog
  --with-extra-cxxflags=<options>
                        pass extra options to C++ compiler
  --with-extra-cflags=<options>
                        pass extra options to C compiler
  --with-extra-ldflags=<options>
                        pass extra options to linker (via C/C++)
  --use-static-gcc      use static gcc libs instead of shared libgcc_s (useful for gcc compiler,
                        that was builded with --enable-shared [default]; if compiler was builded
                        with --disable-shared, static libraries will be used in any case)
  --clean               remove custom settings (file ${configmak})
                        and use default values
  --with-cxx=<name>     use <name> as C++ compiler (use --target= for cross-compilation)
  --with-cc=<name>      use <name> as C compiler (use --target= for cross-compilation)
  --use-compiler-family=<name> use compiler family; one of:
                        gcc      GNU compilers (default)
                        icc      Intel compilers
                        aCC      HP's aCC compilers
                        CC       SunPro's CC compilers
                        bcc      Borland's compilers
  --without-debug       don't build debug variant
  --without-stldebug    don't build STLport's STLP_DEBUG mode
  --enable-static       build static
  --disable-shared      don't build shared 
  --with-lib-motif=<motif>
                        Use this option to customize the generated library name.
                        The motif will be used in the last place before version information,
                        separated by an underscore, ex:
                        stlportd_MOTIF.5.0.lib
                        stlportstld_static_MOTIF.5.1.lib
  --without-thread      Per default STLport libraries are built in order to be usable
                        in a multithreaded context. If you don't need this you can ask
                        for a not thread safe version with this option.
  --without-rtti        Disable RTTI when building libraries.
  --with-static-rtl
  --with-dynamic-rtl
                        Enables usage of static (libc.lib family) or dynamic (msvcrt.lib family)
                        C/C++ runtime library when linking with STLport. If you want your appli/dll
                        to link statically with STLport but using the dynamic C runtime use
                        --with-dynamic-rtl; if you want to link dynamicaly with STLport but using the
                        static C runtime use --with-static-rtl. See README.options for details.
                        Don't forget to signal the link method when building your appli or dll, in
                        stlport/stl/config/host.h set the following macro depending on the configure
                        option:
                        --with-static-rtl  -> _STLP_USE_DYNAMIC_LIB"
                        --with-dynamic-rtl -> _STLP_USE_STATIC_LIB"
  --windows-platform=<name>
                        Targetted OS when building for Windows; one of:
                        win95   Windows 95
                        win98   Windows 98
                        winxp   Windows XP and later (default)

Environment variables:

  \$CXX                 C++ compiler name (use --target= for cross-compilation)
  \$CC                  C compiler name (use --target= for cross-compilation)
  \$CXXFLAGS            pass extra options to C++ compiler
  \$CFLAGS              pass extra options to C compiler
  \$LDFLAGS             pass extra options to linker (via C/C++)

  Options has preference over environment variables.
