The problem with linking is that there is no crt*.o, which are the asm startup stubs for the code. I'm going to do a couple things, look at netbsd, comapre to ours for i386 and see what can be done. Someone gave me code for a bootstrapping kernel, and i'm going to put this up in the repository i'm going to setup. I'm trying to get it to compile under my usr/src/sys/sparc64 dir... we'll see soon. I can't get solaris ld to link the files into an executable even when i provide an on-sparc compiled 'main' and use sunproC compiler. Remeber, this is new to me, i'll figure it out soon. I think we still have 'bad magic' in the object files so the linker refuese to link them. Also, gcc's asm output does not agree with sunPro either so it's difficult to test that... By glancing over the simple asm code i've generated it looks proper. What i hope to do is use the kernel code supplied to me for printf stuff, basically get it to boot on the sparc via tftp and see what i can get it to print out and such. -Alfred > > -- > Christopher Nielsen > Scient: The eBusiness Systems Innovator > <http://www.scient.com>; > cnielsen@scient.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-sparc" in the body of the message
