NAME
tcc - Tiny C Compiler
SYNOPSIS
usage: tcc [options] [infile1 infile2...] [-run infile args...]
DESCRIPTION
TCC options are a very much like gcc options. The main difference is that TCC can also
execute directly the resulting program and give it runtime arguments.
Here are some examples to understand the logic:
"tcc -run a.c"
Compile a.c and execute it directly
"tcc -run a.c arg1"
Compile a.c and execute it directly. arg1 is given as first argument to the "main()"
of a.c.
"tcc a.c -run b.c arg1"
Compile a.c and b.c, link them together and execute them. arg1 is given as first
argument to the "main()" of the resulting program.
"tcc -o myprog a.c b.c"
Compile a.c and b.c, link them and generate the executable myprog.
"tcc -o myprog a.o b.o"
link a.o and b.o together and generate the executable myprog.
"tcc -c a.c"
Compile a.c and generate object file a.o.
"tcc -c asmfile.S"
Preprocess with C preprocess and assemble asmfile.S and generate object file
asmfile.o.
"tcc -c asmfile.s"
Assemble (but not preprocess) asmfile.s and generate object file asmfile.o.
"tcc -r -o ab.o a.c b.c"
Compile a.c and b.c, link them together and generate the object file ab.o.
Scripting:
TCC can be invoked from scripts, just as shell scripts. You just need to add
"#!/usr/local/bin/tcc -run" at the start of your C source:
#!/usr/local/bin/tcc -run
#include <stdio.h>
int main()
{
printf("Hello World\n");
return 0;
}
TCC can read C source code from standard input when - is used in place of infile. Example:
echo 'main(){puts("hello");}' | tcc -run -
OPTIONS
-v Display current TCC version, increase verbosity.
-print-search-dirs
Print the name of the configured installation directory and a list of program and
library directories tcc will search.
-c Generate an object file.
-o outfile
Put object file, executable, or dll into output file outfile.
-Bdir
Set the path where the tcc internal libraries can be found (default is
PREFIX/lib/tcc).
-bench
Output compilation statistics.
-run source [args...]
Compile file source and run it with the command line arguments args. In order to be
able to give more than one argument to a script, several TCC options can be given
after the -run option, separated by spaces. Example:
tcc "-run -L/usr/X11R6/lib -lX11" ex4.c
In a script, it gives the following header:
#!/usr/local/bin/tcc -run -L/usr/X11R6/lib -lX11
#include <stdlib.h>
int main(int argc, char **argv)
{
...
}
Preprocessor options:
-Idir
Specify an additional include path. Include paths are searched in the order they are
specified.
System include paths are always searched after. The default system include paths are:
/usr/local/include, /usr/include and PREFIX/lib/tcc/include. (PREFIX is usually /usr
or /usr/local).
-Dsym[=val]
Define preprocessor symbol sym to val. If val is not present, its value is 1.
Function-like macros can also be defined: -DF(a)=a+1
-Usym
Undefine preprocessor symbol sym.
Compilation flags:
Note: each of the following warning options has a negative form beginning with -fno-.
-funsigned-char
Let the "char" type be unsigned.
-fsigned-char
Let the "char" type be signed.
-fno-common
Do not generate common symbols for uninitialized data.
-fleading-underscore
Add a leading underscore at the beginning of each C symbol.
Warning options:
-w Disable all warnings.
Note: each of the following warning options has a negative form beginning with -Wno-.
-Wimplicit-function-declaration
Warn about implicit function declaration.
-Wunsupported
Warn about unsupported GCC features that are ignored by TCC.
-Wwrite-strings
Make string constants be of type "const char *" instead of "char *".
-Werror
Abort compilation if warnings are issued.
-Wall
Activate all warnings, except -Werror, -Wunusupported and -Wwrite-strings.
Linker options:
-Ldir
Specify an additional static library path for the -l option. The default library paths
are /usr/local/lib, /usr/lib and /lib.
-lxxx
Link your program with dynamic library libxxx.so or static library libxxx.a. The
library is searched in the paths specified by the -L option.
-shared
Generate a shared library instead of an executable.
-soname name
set name for shared library to be used at runtime
-static
Generate a statically linked executable (default is a shared linked executable).
-rdynamic
Export global symbols to the dynamic linker. It is useful when a library opened with
"dlopen()" needs to access executable symbols.
-r Generate an object file combining all input files.
-Wl,-Ttext,address
Set the start of the .text section to address.
-Wl,--oformat,fmt
Use fmt as output format. The supported output formats are:
"elf32-i386"
ELF output format (default)
"binary"
Binary image (only for executable output)
"coff"
COFF output format (only for executable output for TMS320C67xx target)
-Wl,-rpath=path
Set custom library search path
Debugger options:
-g Generate run time debug information so that you get clear run time error messages: "
test.c:68: in function 'test5()': dereferencing invalid pointer" instead of the
laconic "Segmentation fault".
-b Generate additional support code to check memory allocations and array/pointer bounds.
-g is implied. Note that the generated code is slower and bigger in this case.
Note: -b is only available on i386 for the moment.
-bt N
Display N callers in stack traces. This is useful with -g or -b.
Note: GCC options -Ox, -fx and -mx are ignored.
