Why not? If you have enough room on your HD then install it! I think we have to
start from something. But Jakub Jelinek pointed out that we need a better
sparc64 compiler. I agree with this, but if we can do the port without putting
our hands in the compiler I think the "better sparc64 compiler" will wait.
Sorry.
So, in the weekend please do these things for me (us):
1) try to install UltraP on your UltraSparc, and tell us if it works, and if
you think it's a solution for the cross-compiling vs compiling problem. If it
is we continue on UltraP and abandon every cross-compiling project.
2) Do some test on UltraP. If you install it try to build something (the
kernel, or programs) so we can know if it's stable enough. I know it's
stupid to think if it builds the kernel it will work for us, but it's a test, a
stupid test, but a test. 8)
I would do these things by myself, but I have no Ultra, so...
I can try to build a cross-compiler for Ultra (host i386, target Ultra) but it
does not seem a good idea. I have read the install file and it does not seem so
easy, expecially if you have no Ultra to test if it works... 8(
However I'll try to build something and Monday I'll tell you what I have done.
I'll start from gcc2.8 (I know it's not stable), or egcs1.1b (Again I know,
it's not so good) but I'll try.
What I want to obtain is a cross-compiler (as I said host i386, target Ultra)
but then I need the linker and the assember.... 8(
About a "better sparc64 compiler": if we cannot use a gcc compiler, or an egcs
compiler, or "XYZ" compiler, I think we must improve gcc and do the
Sparc64 compiler. Sorry, this is the situation. I don't know if someone is
interested in this.... 8(

Hum... Ok. But we have to fix this. We have to decide what to use, so everyone
can download the right package from Internet.
