C Scripting Everywhere - The Smallest ANSI C compiler
-
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.
- 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.
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.
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
.
Please read tcc-doc.html to have all the features of TCC.
Additional information is available for the Windows port in tcc-win32.txt.
