    TinyCC
    ======

    This file contains specific information for usage of TinyCC
    under MS-Windows.  See tcc-doc.html to have all the features.


    Installation from the binary ZIP package:
    -----------------------------------------
    Unzip the package to a directory of your choice.
    

    Set the system PATH:
    --------------------
    To be able to invoke the compiler from everywhere on your computer by
    just typing "tcc", please add the directory containing tcc.exe to your
    system PATH.


    Include and library search paths
    --------------------------------
    On windows,  the standard "include" and "lib" directories are searched
    relatively from the location of the executables (tcc.exe, libtcc.dll).


    Examples:
    ---------
    Open a console window (DOS box) and 'cd' to the examples directory.

    For the 'Fibonacci' example type:

	tcc fib.c

    For the 'Hello Windows' GUI example type:

	tcc hello_win.c

    For the 'Hello DLL' example type

	tcc -shared dll.c
	tcc -impdef dll.dll (optional)
        tcc hello_dll.c dll.def


    Using libtcc as JIT compiler in your program
    --------------------------------------------
    Check out the 'libtcc_test' example:

    - Running it from source:
        tcc -I libtcc libtcc/libtcc.def -run examples/libtcc_test.c

    - Compiling with TCC:
        tcc examples/libtcc_test.c -I libtcc libtcc/libtcc.def

    - Compiling with MinGW:
        gcc examples/libtcc_test.c -I libtcc libtcc.dll -o libtcc_test.exe

    - Compiling with MSVC:
        lib /def:libtcc\libtcc.def /out:libtcc.lib
        cl /MD examples/libtcc_test.c -I libtcc libtcc.lib


    Import Definition Files:
    ------------------------
    To link with Windows system DLLs, TCC uses import definition
    files (.def) instead of libraries.

    The now built-in 'tiny_impdef' program may be used to make
    additional .def files for any DLL. For example

        tcc -impdef [-v] opengl32.dll [-o opengl32.def]

    Put opengl32.def into the tcc/lib directory.  Specify -lopengl32 at
    the TCC commandline to link a program that uses opengl32.dll.


    Header Files:
    -------------
    The system header files (except _mingw.h) are from the MinGW
    distribution:

	http://www.mingw.org/

    From the windows headers, only a minimal set is included.  If you need
    more,  get MinGW's "w32api" package.  Extract the files from "include"
    into your "tcc/include/winapi" directory.

    If the latest mingw headers don't play nice with the TinyCC headers,
    there's also TinyCC-specific win32 headers package which contains
    an "include" dir. Files in that dir are additional to the built-in
    include files. At the time of writing there are few files in that
    package which also exist as built-in headers:

        unistd.h
        winapi/qos.h
        winapi/winnls.h
        winapi/ws2ipdef.h
        winapi/ws2tcpip.h
        winapi/windows.h
        winapi/winsock2.h

    With the exception of winapi/winsock2.h, these should overwrite the
    built-in headers (unistd.h and winapi/windows.h are enhanced in that
    package, winapi/winsock2.h is older than the built-in file - and with
    less definitions, and the rest are identical).

    The latest package at the time of writing is winapi-full-for-0.9.27.zip
    which works well also with TinyCC 0.9.28rc, and is available at:

        http://download.savannah.nongnu.org/releases/tinycc/


    Resource Files:
    ---------------
    TCC can link windows resources in coff format as generated by MinGW's
    windres.exe.  For example:

        windres -O coff app.rc -o appres.o
        tcc app.c appres.o -o app.exe


    Tiny Libmaker:
    --------------
    The now built-in tiny_libmaker tool by Timovj Lahde can be used as
    'ar' replacement to make a library from several object files:

	tcc -ar [rcsv] library objectfiles ...


    Compilation from source:
    ------------------------
    * You can use the MinGW and MSYS tools available at
        http://www.mingw.org
        http://www.mingw-w64.org
        http://www.msys2.org

      Untar the TCC archive and type in the MSYS shell:
        ./configure [--prefix installpath]
        make
        make install

      The default install location is c:\Program Files\tcc

      Cygwin can be used too with its mingw cross-compiler installed:
        ./configure --cross-prefix=i686-w64-mingw32-
        (the prefix may vary)

    * Alternatively you can compile TCC with just GCC from MinGW using
        > build-tcc.bat (from the win32 directory)

      Also MSVC can be used with the "VSTools Developer Command Prompt":
        > build-tcc.bat -c cl

      or with an existing tcc (needs to be in a different directory)
        > build-tcc.bat -c some-tcc-dir\tcc.exe

      Also you can copy/install everything into another directory:
        > build-tcc.bat -i <dir>

    Limitations:
    ------------
    - On the object file level, currently TCC supports only the ELF format,
      not COFF as used by MinGW and MSVC.  It is not possible to exchange
      object files or libraries between TCC and these compilers.

      However libraries for TCC from objects by TCC can be made using
        tcc -ar lib.a files.o ,,,

    - No leading underscore is generated in the ELF symbols.

    WinAPI Help and 3rd-party tools:
    --------------------------------
    The Windows API documentation (Win95) in a single .hlp file is
    available on the lcc-win32 site as "win32hlp.exe" or from other
    locations as "win32hlp_big.zip".

    A nice RAD tool to create windows resources (dialog boxes etc.) is
    "ResEd", available at the RadASM website.
