libc.a is 0 byte about cc6303 HOT 12 CLOSED

I'd expect that - it's a placeholder as nobody has put together a libc for it outside of the Fuzix one.

from cc6303.

ok. Just reporting that most of my compilations tries lead to an error "bad object file" relating libc.a.
Even a nearly empty c file, with command cc68 -tmc10 foo.c -o foo
lead to that error (I'm just following the doc).

I've tweaked it to create a blank libc.a. I don't remember why I originally made it a blank file instead, possibly some old tools didn't accept "ar rc libc.a" without anything in it.

I can explain you my initial goal. I'm trying to use Cross-lib, so I compiled and installed cc6303. Fabrizzio do not have any problem with using your compiler (cygwin 32 bits) but I can not compile anything (cygwin 64 bits). I mentionned that the problem seem to be libc.a, but I have no use of it :) ... If you have anyidea so that I could have a successful cross-lib usage, then it would be great (zz88dk is also failing). Fabrizzio think this is the "64 bits" difference that make all my problems happen.

@christopheKohler @EtchedPixels Cross-Lib is not technically related to this issue. He is testing the mc10 target.
@christopheKohler has reported that he has not succeded in compiling a simple helloworld example for the mc10 target.
I can with no problem. My set is Windows 64-bit/Cygwin 32-bit

Here is the log for CROSS-LIB. We can see the fail on libc.a.

@EtchedPixels even this exampe won't compile (as reported to me by @christopheKohler ) with cc68 -tmc10 foo.c -o foo

int main(void)
{
        int hello;
        
        hello = 12;
        
        return 0;
}

and produce the error

Hi. Any fix have been done for cygwin 64bits compilation ?

from cc6303.

I just changed it to build a real library with nothing in it. That seems to work for me with the GNU based ar tools

from cc6303.

ok, I'll give it a new try.
Thanks.

from cc6303.

Cool - I've been splitting the fuzix libc a bit to use for other targets so I'll probably import that at some point too

from cc6303.

I comfirm all is ok now. I compiled all and libc.a is 8 bytes long now (instead of 0) and all the above various compilations are going nicely now. Thanks.
