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.

|
|
1) Installation on a i386/x86_64/arm Linux/OSX/FreeBSD host
|
|
|
|
./configure
|
|
make
|
|
make test
|
|
make install
|
|
|
|
Notes: For OSX and FreeBSD, gmake should be used instead of make.
|
|
For Windows read tcc-win32.txt.
|
|
|
|
makeinfo 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'.
|
