Re: [ECOS] Another redboot compile issue

[John Newlin <jnewlin at rawbw dot com>]

I mispoke, libextras.a has the redboot_*.o files in it.
But do not get linked in, unless the files are specified on the link
line.

in the hal/common/.../hal.cdl there is a compile line that attempts to
compile everything in libextras.a into extras.o.  However, my extras.o is
ending up empty.

Something like:
$(CC) $(CFLAGS) -nostdlib -Wl,-r -Wl,--whole-archive -o $@ $<

Then extras.o is in my target.ld file.

Thanks again for the help!
