No.

That's why I want to install Linux (Debian probably, they have an ARM version) in QEMU, simulating an ARM machine. I would like the ability to natively run the dev tools on it, no cross-compiling or having to transfer files from my desktop machine's hard drive to the VM image.

And I thought that I was programming in 32 bit asm all the time.

I started to follow this article:

http://dev.emcelettronica.com/instal...ebian-arm-qemu

and it all went file, until this (see attachment). I already tried with another mirror and it still does this. What should I do?

You can tell the compiler and the linker that you want to compile a 32 bit program instead of 64.

Code:

as --32  max.s -o max.o
ld -melf_i386 max.o -o max

Will is still work in 64-bit linux?

And still, how do I fix that Debian ARM error?

whizje · 03-05-2010, 03:52 PM

Yes that makes it work in 64 bit, and sorry i don't know about ARM error.

What about network access from QEMU in general ?

What do you mean?

QEMU may work without network access. I don't remember whether network access is enabled by default or not. I think one needs to provide '-net user' on QEMU command line.

Have you verified the article against QEMU documentation or, at least, built-in help message ?

Can you in Debian ARM Linux you are dealing with check network access before installing anything ? By, say,

ping yahoo.com

or similar ?

Still no matter what I try I can't get it to work.

Isn't it possible to have it install from a CD image instead of all that complication?

I was following this article: http://www.aurel32.net/info/debian_arm_qemu.php .

Debian has a configuration file with the list of mirrors, I don't remember what it is, but is well documented in all that apt* stuff.

Same error.

Please explain to me why I can't just use the ARM install CD?

smeezekitty · 03-05-2010, 07:38 PM

I had some fun with qemu too - only this was powerpc: http://www.linuxquestions.org/questi...?highlight=PPC

The Q&A section at the bottom of http://dev.emcelettronica.com/instal...ebian-arm-qemu regarding modifying gpg behavior got me past the problem you describe. It wasn't obvious to me how to set up the network during the installation; turns out just pressing Enter at all of the dialogs worked for me.

I had some problem...
problem seems to be in gpg verify.

I just skipped gpg verify:
when installation start switch to tty2 (alt+f2)
then press enter and type "mv /usr/bin/gpgv /usr/bin/gpgvb"
then switch back to tty1 (alt+f1) and continue with installation

!! REMEMBER THAT SKIPPING GPG VERIFY IS UNSECURE !!
(you can be victim of man-in-middle attack)
