TinyCC-PE
|
||||
---------
|
||||
|
||||
TinyCC (aka TCC) is a small but hyperfast C compiler,
|
||||
written by Fabrice Bellard,
|
||||
|
||||
|
||||
TinyCC-PE is the TinyCC compiler with an extension to
|
||||
write PE executables for MS-Windows.
|
||||
|
||||
|
||||
Features:
|
||||
---------
|
||||
|
||||
TinyCC-PE can produce console applications, native windows
|
||||
GUI programs and DLL's.
|
||||
|
||||
Most of the features pointed out by Fabrice Bellard for the
|
||||
original version are still valid, i.e:
|
||||
|
||||
- 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.
|
||||
|
||||
|
||||
Installation:
|
||||
-------------
|
||||
|
||||
Just unzip the package to a directory anywhere on your computer.
|
||||
|
||||
|
||||
Examples:
|
||||
---------
|
||||
|
||||
For the 'Fibonacci' console example type from the command line:
|
||||
|
||||
tcc examples\fib.c
|
||||
|
||||
|
||||
For the 'Hello Windows' GUI example:
|
||||
|
||||
tcc examples\hello_win.c
|
||||
|
||||
|
||||
For the 'Hello DLL' example:
|
||||
|
||||
tcc -shared examples\dll.c
|
||||
tcc examples\hello_dll.c examples\dll.def
|
||||
|
||||
|
||||
Import Definitions:
|
||||
-------------------
|
||||
|
||||
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':
|
||||
|
||||
tiny_impdef.exe opengl32.dll
|
||||
|
||||
or to the same effect:
|
||||
|
||||
tcc -lkernel32 -run tiny_impdef.c opengl32.dll
|
||||
|
||||
|
||||
Header Files:
|
||||
-------------
|
||||
|
||||
The system header files, except '_mingw.h', are from the
|
||||
2.0 mingw distribution. See also: http://www.mingw.org/
|
||||
|
||||
|
||||
Compile TCC:
|
||||
------------
|
||||
|
||||
With TCC itself just say:
|
||||
|
||||
tcc src\tcc.c -lkernel32 -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.
|
||||
|
||||
|
||||
Documentation and License:
|
||||
--------------------------
|
||||
|
||||
TCC is distributed under the GNU Lesser General Public License
|
||||
(see COPYING file).
