Hi All,
$cp -f 001.s 002.s
$mips-elf-as -O0 -G 0 -mips32r2 -EL 001.s 002.s
002.s: Assembler messages:
002.s:1: Error: symbol `_Init' is already defined
It seems that `as` invoke `ld` to link the object files after comipling?
So how can I inform `as` not to do linking after compiling?
Best Regards

It is not invoking ld after assembling.
Please read this:

So what do the error messages mean here?

It means that you have duplicate symbols between the two files.

So, if `as` deals with more than one input files, it will combine the
assembly results of each input file to one output object file?

No, it will concatenate the source files as it says on the page I sent
you.

I get it. I misunderstood the behaviors of `as`. I thought it worked
like `gcc` to output one object file respectly for one input file if
it did with multiple input files.
