TinyCC-PE
---------
TinyCC
======
TinyCC (aka TCC) is a small but hyperfast C compiler,
written by Fabrice Bellard,
This file contains some additional information for usage of TinyCC
under MS-Windows:
TinyCC-PE is the TinyCC compiler with an extension to
write PE executables for MS-Windows.
Overview:
---------
TinyCC (aka TCC) is a small but hyperfast C compiler, written by
Fabrice Bellard.
TinyCC for MS-Windows can produce console applications, native
windows GUI programs and DLL's.
Features:
---------
The package with under 300kb includes a complete C-compiler with
header files and basic system library support.
TinyCC-PE can produce console applications, native windows
GUI programs and DLL's.
With the -run switch you can run C-sources without any linking
directly from the command line.
Most of the features pointed out by Fabrice Bellard for the
original version are still valid, i.e:
TinyCC can be used as dynamic code generator library in your own
program.
- SMALL! The package with ~400kb includes a complete C-compiler
with header files for console and GUI applications.
- With the -run switch you can run C-sources without any
linking directly from the command line.
- TCC can of course compile itself.
TinyCC can of course compile itself.
Compilation: (omit that if you use the binary ZIP package)
------------
You must use the MinGW and MSYS tools available at

Installation: (from the binary ZIP package)
-------------
Just unzip the package to a directory anywhere on your computer.
The binary package does not include libtcc. If you want tcc as
dynamic code generator, please use the source code distribution.
Examples:
---------
For the 'Fibonacci' console example type from the command line:

Import Definitions:
-------------------
Import Definition Files:
------------------------
To link with Windows system DLLs, TinyCC uses import definition
files (.def) instead of libraries.
TinyCC-PE searches and reads import definition files similar
to libraries.
The included 'tiny_impdef' program may be used to make .def files
for any DLL, e.g for an 'opengl32.def':
The included 'tiny_impdef' program may be used to make additional
.def files for any DLL. For example:
tiny_impdef.exe opengl32.dll
or to the same effect:
tcc -run tiny_impdef.c opengl32.dll
To use it, put the opengl32.def file into the tcc/lib directory,
and specify -lopengl32 at the tcc commandline.
Resource Files:
---------------
TinyCC-PE can now link windows resources in coff format as generated
by MINGW's windres.exe. For example:

tcc app.c appres.o -o app.exe
Tiny Libmaker:
--------------
The included tiny_libmaker tool by Timovj Lahde can be used as
'ar' replacement to make a library from several object files.
Header Files:
-------------
The system header files, except '_mingw.h', are from the
3.7 mingw distribution. See also: http://www.mingw.org/
Compile TCC:
------------
With TCC itself just say:
tcc src\tcc.c -o tcc.new.exe
Other compilers like mingw-gcc or msvc work as well.
To make libtcc1.a, you need 'ar' from the mingw binutils.
The system header files (except _mingw.h) are from the mingw
distribution (http://www.mingw.org/).
