Configuration utility.

Usage:

  configure [options]

Available options:

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

  --help                Print this help message and exit

  --with-stlport=<dir>  use STLport in catalog <dir>

  --with-mwcw=<dir>     Metrowerks CodeWarrior compiler catalog (useful for mw* compilers)
                        i.e. something like "c:/Program Files/Metrowerks/CodeWarrior"

  --with-nwsdk=<dir>    Use Novell NDK/SDK from this catalog (useful for *-*-netware target)
                        i.e. something like "c:/Novell/ndk/nwsdk"

  --no-cygwin           Specific cygwin distribution option. Use it to build STLport using
                        the cygwin tools but without dependency on the cygwin1.dll

  --with-extra-cxxflags=<options>
                        Pass extra options to C++ compiler

  --not-thread-safe     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.

  --with-boost=<dir>    Request use of boost support (www.boost.org). For the moment only the boost
                        type_traits library is used to get type information and to implement some
                        specific workaround not directly implemented by STLport. To use the same
                        support using STLport don't forget to define _STLP_USE_BOOST_SUPPORT in
                        stlport/stl/config/user_config.h file.

  --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

  --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
