Tiny C Compiler Build Status

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 Linux host (for Windows read tcc-win32.txt)
./configure
make
make test
make install

By default, tcc is installed in /usr/local/bin. ./configure --help shows configuration options.

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.

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.
