Tiny C Compiler - C Scripting Everywhere - The Smallest ANSI C compiler
-----------------------------------------------------------------------
Features:
--------
- SMALL! You can compile and execute C code everywhere, for example on
rescue disks.
- FAST! tcc generates optimized x86 code. No byte code
overhead. Compile, assemble and link about 7 times faster than 'gcc
-O0'.
- UNLIMITED! Any C dynamic library can be used directly. TCC is
heading torward full ISOC99 compliance. TCC can of course compile
itself.
- SAFE! tcc includes an optional memory and bound checker. Bound
checked code can be mixed freely with standard code.
- Compile and execute C source directly. No linking or assembly
necessary. Full C preprocessor included.
- C script supported : just add '#!/usr/local/bin/tcc -run' at the first
line of your C source, and execute it directly from the command
line.
Documentation:
-------------
1) Installation on a i386/x86_64/arm Linux/OSX/FreeBSD host (for Windows read tcc-win32.txt)
Note: For OSX and FreeBSD, gmake should be used instead of make.
./configure
make
make test
make install
Alternatively, out-of-tree builds are supported: you may use different
directories to hold build objects, kept separate from your source tree:
mkdir _build
cd _build
../configure
make
make test
make install
Texi2html must be installed to compile the doc.
By default, tcc is installed in /usr/local/bin.
./configure --help shows configuration options.
2) Introduction
We assume here that you know ANSI C. Look at the example ex1.c to know
what the programs look like.
The include file <tcclib.h> can be used if you want a small basic libc
include support (especially useful for floppy disks). Of course, you
can also use standard headers, although they are slower to compile.
You can begin your C script with '#!/usr/local/bin/tcc -run' on the first
line and set its execute bits (chmod a+x your_script). Then, you can
launch the C code as a shell or perl script :-) The command line
arguments are put in 'argc' and 'argv' of the main functions, as in
ANSI C.
3) Examples
ex1.c: simplest example (hello world). Can also be launched directly
as a script: './ex1.c'.
ex2.c: more complicated example: find a number with the four
operations given a list of numbers (benchmark).
ex3.c: compute fibonacci numbers (benchmark).
ex4.c: more complicated: X11 program. Very complicated test in fact
because standard headers are being used ! As for ex1.c, can also be launched
directly as a script: './ex4.c'.
ex5.c: 'hello world' with standard glibc headers.
tcc.c: TCC can of course compile itself. Used to check the code
generator.
tcctest.c: auto test for TCC which tests many subtle possible bugs. Used
when doing 'make test'.
4) Full Documentation
Please read tcc-doc.html to have all the features of TCC.
Additional information is available for the Windows port in tcc-win32.txt.
