I'm trying to help someone port a compiler (http://mlton.org) that generates x86 assembly code, but we are having difficulty with calls to external C functions. If we are calling a function _foo directly, we get a error from ld:

external relocation entries in non- writable section (__TEXT,__text) symbols: _foo

but if we put in a stub as suggested by the "Mac OS X Assembler Reference"

	.symbol_stub
	L_foo_stub:
	.indirect_symbol _foo
		hlt ; hlt ; hlt ; hlt ; hlt

we get the following error from the assembler:

	missing indirect symbols for section (__TEXT,__symbol_stub)

Can someone explain what the root cause of this error message might be?

	- John
