Compiling packages from source on Ultrasparc

Compiling packages from source on Ultrasparc

[Shanti Katta]

Hi,
I understand that userland is 32-bit on Ultrasparc. I am trying to
compile user-mode-linux on Ultrasparc, and I guess I need to compile it
in 32-bit mode for it to run as a normal user-level process. UML make
use of certain files in asm-{base-arch} during compilation. Now, to
compile uml in 32-bit mode, I did not include any flags in
makefiles(like -m64, -mcpu=ultrasparc) that would include 64-bit
specific asm code.
My question is that, what difference does it make when I compile UML, in
a sparc32 shell, as compared to the above process without executing the
sparc32 shell. I understand that if compiled in sparc32 shell, it
recognizes the host-arch as "sparc" instead of "sparc64". But other than
that, does it make any other difference? I am also not sure, which is
the right method for compiling UML.
Any pointers will be appreciated.

-Shanti

To compile it as a 32bit app, use the sparc32 wrapper to be safe, or
pass sparc as the target arch for UML.

   I understand that userland is 32-bit on Ultrasparc. I am trying to
   compile user-mode-linux on Ultrasparc,

Maybe after you post about this ordeal 500 more times, someone
will answer.

Take this to be posted 500 more times...does it really work?

My point is that when you post a question 2 or more times
and nobody responds, posting the question some more isn't
going to arrive you at a response.

So please stop.

I did receive some constructive responses to my posts and AFAIK I have
never posted the same question twice. Although, all those posts relate
to different aspects of the same problem.

How else am I supposed to get help?
