ld: library not found for -lcrt0.o on OSX 10.6 with gcc/clang -static flag

When I try to build the following program:

#include <stdio.h>

int main(void)
{
  printf("hello world\n");
  return 0;
}

On OS X 10.6.4, with the following flags:

gcc -static -o blah blah.c

It returns this:

ld: library not found for -lcrt0.o
collect2: ld returned 1 exit status

Has anyone else encountered this, or is it something that noone else has been affected with yet? Any fixes?

Thanks

This won’t work. From the man page for gcc:

This option will not work on Mac OS X unless all libraries (including libgcc.a) have also been compiled with -static. Since neither a static version of libSystem.dylib nor crt0.o are provided, this option is not useful to most people.

Per Nate's answer, a completely static application is apparently not possible - see also man ld:

-static Produces a mach-o file that does not use the dyld. Only used building the kernel.

The problem in linking with static libraries is that, if both a static and a dynamic version of a library are found in the same directory, the dynamic version will be taken in preference. Three ways of avoiding this are:

1. Do not attempt to find them via the -L and -l options; instead, specify the full paths, to the libraries you want to use, on the compiler or linker command line.

   $ g++ -Wall -Werror -o hi /usr/local/lib/libboost_unit_test_framework.a hi.cpp

2. Create a separate directory, containing symbolic links to the static libraries, use the -L option to have this directory searched first, and use the -l option to specify the libraries you want to use.

   $ g++ -Wall -Werror -L ./staticBoostLib -l boost_unit_test_framework -o hi hi.cpp

3. Instead of creating a link of the same name in a different directory, create a link of a different name in the same directory, and specify that name in a -l argument.

   $ g++ -Wall -Werror -l boost_unit_test_framework_static -o hi hi.cpp
