**********************************************************************

STLport is a full ANSI C++ Standard library.

This distribution contains STLport sources only, no binaries.

To use STLport iostreams, locale and complex numbers, you have to build STLport

library from sources in "build/lib" directory and link your programs with it.

Starting with 5.0 the 'wrapper' mode is not supported anymore. You cannot use native

compiler iostreams implementation with STLport STL (see doc/FAQ for explanations).

Now you have to choose between STLport iostreams or no iostreams.

==== Unpacking and installing STLport ==========

1) Unpack STLport archive to a directory accessible during compilation.

   NOTE: DO NOT overwrite header files coming with the compiler, even if you made

   a backup - this won't work! Most probably, you've already unpacked the archive before

   reading this file though ;)

2) Make sure "stlport" directory of this distribution comes before compiler's one 

   in your include paths when you compile the project.

   Note: for SunPro CC 5.0 and higher, there used to be special directory "stlport/SC5"

	 this is now obsolete, please make sure you do not use it anymore.

3) Make sure you do not rename this "stlport" subdirectory -

   that may result in compilation errors.

   NOTE:  Your compiler should be recognized by STLport source code with no configuring.

          Please edit appropriate configuration header for your compiler

          directly if you have to make compiler-specific configuration changes

          (see stlport/stl/config). 

4)  Run:

    configure --help

    Depending on your environment, Windows command shell or Unix like shell,

    configure.bat or configure script will be run respectively. For Windows users

    running configure script is mandatory in order to declare the compiler you are

    going to use.

5)  Go to "build/lib" subdirectory. It contains various makefiles for different

    compilers and 'make' utilities (GNU Make and Microsoft's nmake supported).

    Verify you can do command line compiles. IDE users may have to do something 

    special, like add environment variables (for Microsoft) or install 

    additional compiler components (for Metrowerks), before they can use their 

    command line compilers (see doc/README.xxxx for additionnal information).

    configure script should have already created a Makefile file so that you only

    have to call 'make' or 'nmake' (for some platforms GNU make might be hidden

    behind 'gmake').

    IMPORTANT:

    If you DO NOT plan to use STLport iostreams and/or locale implementation but just

    the STL, you do not have to build the library.

    If you have decided to disable STLport iostreams and locale using _STLP_NO_IOSTREAMS

    configuration macro in stlport/stl/config/user_config.h, you may stop reading here.

==== Building STLport iostreams library ==========

Below are step-by-step instructions to build STLport streams library. This is a general

build process description, for a more detailed one check README files in the doc folder:

5)  Using appropriate make command (make or nmake), do

      make clean install

    to build the STLport libraries. Make files are set up to build several different

    flavors - debug/nondebug, static/dynamic versions. But not all flavors will be build

    by default. See build/lib/README for other make targets.

    Note: 'install' target work slightly different than usual - it installs libraries into

    <STLport root dir>/lib and bin catalogs, NOT IN SYSTEM CATALOG. You can do the system

    install by just copying stlport and lib folder to the destination of your choise. For

    example on UNIX-like platforms this can be done with the following commands:

      su

      tar cf - stlport | (cd /usr/local/include; tar xf -)

      chmod -R a+r /usr/local/include/stlport

      chown -R root:root /usr/local/include/stlport

      (cd lib; tar cf - --exclude=CVS --exclude=.cvsignore .) | (cd /usr/local/lib; tar xf -)

      chown -R root:root /usr/local/lib/libstlport*

      exit

    Note: System install is optional, most of compilers/linkers support searching for includes

    and libs throught out the whole filesystem, just check your documentation on how to achieve

    this.

    If you use cross-compiler, you can find libraries in the <STLport root dir>/lib/<target platform>

    catalog.

6)  If build fails, you may choose to :

     - try fixing the build ;)

     - wait until somebody else will submit corresponding changes to be incorporated in next STLport 

       release/snapshot.

    In case you do patch STLport, please submit your patches to

    https://sourceforge.net/tracker/?atid=766246&group_id=146814&func=browse

==== Linking your application with STLport library ==========

7) Check the build:

    Example:

    - under Linux and other Unixes:

    cd build/test/unit

    make install

    ../../../bin/stl_unit_test

    ../../../bin-g/stl_unit_test

    - under Windows:

    cd build\test\unit

    nmake install

    cd ..\..\..\bin

    stl_unit_test

    stl_unit_testd

    stl_unit_teststld

8) Supply the "lib" subdirectory to the library search path and add desired 

   library to the list of libraries to link with.

   Examples (imagine you have mytest.cpp in the same directory as this file is):

	With GCC     : g++ -pthread -I./stlport mytest.cpp -L./lib/ -lstlport

	With DEC CC  : cxx -I./stlport mytest.cpp -L./lib/ -lstlport

	With SUN CC  : CC -mt -I./stlport mytest.cpp -L./lib/ -lstlport

	.....

   For several compilers supporting auto linking feature (VC++, Borland, DMC),

   you do not have to specify "stlport.M.m.lib" explicitly, as it is being choosen

   and forced to link automatically by "#pragma"'s in compiler config files 

   Appropriate version is being selected based on compiler options and _STLP_DEBUG

   setting. All you have to do is to set library search path for the linker.

	Example :

           cl.exe /I.\stlport mytest.cpp /link /libpath:.\lib /MD

9) If you linked your application with shared STLport library (.so or .dll), please 

   make suze that your .so or .dll can be found by the dynamic linker. 

   Under Windows, the paths searched depend on the particular flavor, see the MSDN 

   documentation for LoadLibrary at http://msdn.microsoft.com. The easiest ways are to

   either modify the PATH environment variable or copy all .dll's next to the 

   executable like it is done per default when unit tests executable are put next

   to dlls. 

   Under Linux, the environment variable LD_LIBRARY_PATH can be adjusted to point

   to the dir containing .so. See the manpage for ld.so for more info.

10) STLport builds only multithreaded libraries, so your application should be compiled

   as multithreaded, too. Use -pthread (or -pthreads on Solaris) option for GCC, -mt for SunPro,

   /MT for VC, and so on. Sometimes you should define _REENTRANT or something else, depends

   upon platform/compiler. See compiler's and linker's options on command line when you build

   unit tests (build/test/unit) for reference. The last is useful for ANY platform.

11) Don't hesitate to read READMEs (doc/README*, build/lib/README*, build/test/unit/README*)

   and doc/FAQ.

12) Have fun!
