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/bin/tcc -run" at the start of your C source:

               #!/usr/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.

       -c  Generate an object file (-o option must also be given).

       -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/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 (-o option must
           also be given).

       -static
           Generate a statically linked executable (default is a shared linked
           executable) (-o option must also be given).

       -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 (-o option must
           also be given).

       -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)

       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.

       -bt N
           Display N callers in stack traces. This is useful with -g or -b.

       Note: GCC options -Ox, -fx and -mx are ignored.
