[Qemu-devel] Problem compiling with gcc 3.3 on 2.6.14 (Debian)

[Qemu-devel] Problem compiling with gcc 3.3 on 2.6.14 (Debian)

[Emmanuel Charpentier]

Dear List,

I recently upgraded to Linux 2.6.14 (as compiled as a 686 Debian 
package), and found that this distribution, too, has switched to GCC 4 
for kernel.

I tried to recompile a plain vanilla qemu 0.7.2 tarball : I switched to 
gcc 3.3 for this (in /usr/bin : ln -sf gcc-3.3 gcc ; ln -sf gccbug-3.3 
gccbug ; ln -sf cpp-3.3 cpp ), planning to switch back to GCC 4 for 
recompilation of the kqemu subdirectory. This failed.

./configure works OK, compilation starts OK too, but the linking fails :

Strange. Haven't heard of this one before.

Compiling the kqemu module should use the same compiler that the kernel uses
anyways. It doesn't use the same one that qemu uses, but the one in the kernel's
Makefile.

I also notice that your error seems to be with qemu-i386. This binary doesn't use
kqemu at all, so either don't use kqemu (if all you care about is i386-user) or
compile i386-softmmu only (if you want to use kqemu and don't care aboui i386-user).

It is hard to make out the problem when the error messages aren't in english, btw.

Just, I think, it is trying to link with libm.a, that is compiled  
using GCC 4.0, so, the fail.

Doesn't your distro have a gcc_select?

I use it in MacOS X to change between GCC 3.3 and GCC 4.0 and it also  
changes default library locations so statically they never get linked  
with different ABIs.

Compiling i386-softmmu works (and the resulting executable works well 
indeed, at least with kqemu). Compiling x86_64-softmmu gives a $#!+load 
of errors (I'll send a logif someone needs it).

This does not allow to undrstand why the compilation of i386-user fails...

Nope. That's Debian for you : Debian users are supposed to be big hunks 
of programmers, and not to flinch on such petty details (the epitome of 
"Real men don't write in Pascal" mentality...). At least, that's the 
impression you get reading postings of some Ordained Debian Developpers 
(TM) on some Debian mailing lists. The simple notion of Debian end-users 
totally overwhelms them...

Curiously, Debian has such a mechanism for handling "default" choices 
about equivalent programs : the "/etc/alternatives" directory. But some 
ODD (TM) decided, in his (according to himself) infinite wisdom that 
such an easy way to swich gccs was too easy for common users, and that 
it might twarth some obscure utterly Debianish hack.

So you're supposed to "ln -s /usr/bin/gcc-3.3 /usr/bin/gcc # etc ...) ad 
nauseam...

BTW : it would not be fair to pick at Debianers and spare the GCC 
hackers : the whole madness could have been spared with a bit more 
reflection about linking *before* launching GCC4...

</rant>

Ah. If only Debian wasn't the best programming distro of the lot for 
non-system programmers... <Sigh !>

I knew that ; that's whi I switched back to gcc 3.3 for compilation of 
the main package, planning to go back to GCC 4 for kqemu. but comiling 
this one needs a correctly configured qemu tree.

I''l try that. But the point isn't here. That's the first time I saw 
such a problem with qemu. Since what has changed is the kernel (and 
probably parts of the compilation system, BTW : Debian instable is ... 
well ... somewhat unstable...)

OK : I'll translate the error messages :

All is fine and dandy up to the "compilation" (linking, in fact) of 
qemu-i386 :

I didn't read the original message, but this is a non-issue.  It
doesn't matter what compiler was used for libm.a

No, you're bloody well not.  You're supposed to configure applications
to use the correct compiler if they need a particular version.  For
qemu that's --cc.  Not so hard, was it?

I wish you were right... Alas, I stand by my words : the attitude of a 
minority of Debian developpers is on the line of "If it was hard to 
write, it should be hard to use". Unfortunately, this minority has a 
serious overlap with the *very good and active* category...

Case in point : I distinctly reember reading a convoluted thread in one 
of the Debian lists about this /etc/alternative issue for gcc... Was I 
drunk ? Or what ?

Didn't work last time I tried : you may do that at *configure* step. In 
the case of a GCC4 kernel, you have to :
- configure and make with gcc 3.3 (--cc=gcc-3.3 goes into 
config-host.mak. What the host-cc does is fairly well obscur to me (got 
lost in the Makefile/source code), and was undocumented last time I 
pored over Fabrice's pages).
- make clean in the kemu directory
- re-make with GCC 4 : this recompiles only the kqemu part.

If you can suggest a more steamlined way, I'd be happy to hear from it, 
and even more happy to read it on Fabrice's pages or somewhere in the 
documentation...

I don't know what all this rant is about but it's always best to keep the 
system compiler as chosen by the distributor. If you want to use 
alternatives, use CC overrides or other configure option.

Use DKMS for kqemu modules?

[carlo.andreoli]

I would like to try this way on my Mandrake 10.0, but I'm not been
able to find a DKMS RPM for this version (seems like DKMS has been
introduced with the 10.1 release of Mdk), so the Pterjean's RPMs
of kqemu for Mdk 10.0 seems useless.

Can you give me some hint on how to proceed?

Thank you

Carlo

The idiocy of having a system perfectly able to handle alternative 
packages ... except when it isn't, for reasons too obscure to be 
understood by a 31-year computer user (yes, I wrote my first Fortran 
program in 1974..) when he isnt a dedicated system maintainer. I *use* 
computers, dammit, I have not too much time to play system administrator....

That's exactly what I was trying to do. Debian has switched to GCC 4 for 
kernels. But (parts of) QEMU) need gcc 3.4. Hence the raindance..

I missed the doc-"howto" for these options. Last time I tried, I ended 
up with "Incorrect module format" errores and/or bad compilations 
errors. I gave up and learned to change compilers...

No such thing on Debian. They have a (supposedly) nice system 
("module-assistant") for compilong out-of-tree modules... which I never 
quite figured out. When I need an out-oft-tree kernel (which is rare 
nowadays), I still roll my own kernel, à la Neanderthal...

In fact dkms is not available on 10.0 but only on Corporate 3.0
Development CD which is based on 10.0, and as I usually do not use
real 10.0 I did not notice this before.
I'll package it another way as soon as I find time...

He meant before posting the error message to an international list. (Plus,
it's less work than having to translate the errors back to English).
