Patrizio, your bug is clearly different, please report it separately.
Compiles fine on gcc 3.4
Same problem with qemu-user-0.8.1 on gcc 4.1
For the issue with linux-headers-2.6.16, edit rtc.h (/usr/include/linux) and remove the #include ???/interrupt.h It worked for me. I am not totally sure about the exact location, since i don't have my computer with me as i write this. BTW, i even compiled qemu-softmmu with my cflags(the normal ebuild filters them all), and it doesn't like -march=athlon-xp, while -mtune=athlon-xp is fine. ABTW, wouldn't it be nice to activate only certain targets, per use flag probably? I for one will never use ppc or sparc.
i dont think this is gcc-4.1's fault so much as qemu's fault the bad code generated is: case INDEX_op_fnegs: { extern void op_fnegs(); extern char .LC0; memcpy(gen_code_ptr, (void *)((char *)&op_fnegs+0), 23); *(uint32_t *)(gen_code_ptr + 11) = (long)(&.LC0) - (long)(gen_code_ptr + 11) + -4; gen_code_ptr += 23; }

could you please push it upstream?
using gcc 4 won't be supported upstream (http://lists.gnu.org/archive/html/qemu-devel/2005-11/msg00250.html), because it requires several intrusive hacks to try to force gcc to behave as it did for version 3 and makes the use of gcc for core dynamic generation not ideal and fragile, while the use of a hand written code generation is seen as a better long time solution : https://nowt.dyndns.org/ if we want to be compatible with upstream, then gcc3 should be required for building qemu.
I'll try this patch and probably apply it if works as should

(In reply to comment #9) > This is a temp fix, could be used with an ewarn letting amd64 users know that > sparc support in qemu is temp. disabled until gcc-4 fixes are released. This helped me a lot... As a side-note -- perhaps it is time to USE-control built emulators? In fact I need just x86 and definitely not PPC, SPARC, MIPS or ARM...
FYI, qemu-0.8.2 is out and compiles with gcc4 (no need to patch it to fix the compile failure in op.h) even if the sparc target is enable but (as with the workaround) segfaults when running
I'm back from a short vacation, you'll find the updated ebuilds soonish
I have no problems running 0.8.1(-r1) with GCC 4.1.1...do you need more information or is this intended behaviour now?
What's the status on this? I'm getting the same failure with the latest ~amd64, though I'm not sure why it doesn't pull in 0.8.2: In file included from /var/tmp/portage/qemu-softmmu-0.8.1-r1/work/qemu-0.8.1/translate-op.c:37: ./op.h: In function 'dyngen_code': ./op.h:3595: error: expected identifier or '(' before '.' token ./op.h:3597: error: expected expression before '.' token make[1]: *** [translate-op.o] Error 1 make[1]: Leaving directory `/var/tmp/portage/qemu-softmmu-0.8.1-r1/work/qemu-0.8.1/sparc-softmmu' make: *** [all] Error 1 !!! ERROR: app-emulation/qemu-softmmu-0.8.1-r1 failed.
qemu-0.8.2 built with gcc-3 worked on the amd64 I have access.
Does QEmu compile with GCC 4.1.1 then? The ebuilds still have this in them: pkg_setup() { if [ "$(gcc-major-version)" == "4" ]; then eerror "qemu requires gcc-3 in order to build and work correctly" eerror "please compile it with gcc-3" die "gcc 4 cannot build qemu" fi }
After removing the gcc4 block in the ebuild, qemu and related deps compiled correctly with GCC 4.1.1. It didn't run though, segfaults every time. It looks like an upstream deal, as the gcc4 issue is mentioned on the front page.
It runs fine here compiled with GCC 4.1.1 and -march=prescott even. Have you tried reducing your CFLAGS ? I have: CFLAGS="-Os -pipe -march=prescott -mfpmath=sse -fomit-frame-pointer"

using gcc-4?
(In reply to comment #30) > qemu-user 0.8.2 compiles fine here with GCC 4.1.1. > Please remove pkg_setup() It compiles fine, or runs fine? The issue is now not about not compiling, but generating bad code, which results in a segfault every time. Have you tried running it?
It compiles and runs fine for me on x86 with the qemu-0.8.0-gcc4-hacks.patch and qemu-0.8.0-gcc4-opts.patch patches applied.

Thanks for the link. The biggest issue for me is that it reduces performance, which is a significant issue with emulators. I recompiled with gcc 3 and it "feels" faster, although that could be because of an expectation :) Anyone care to benchmark?

(In reply to comment #37) > qemu-user-0.8.0 don't compile on amd64 umm, yeah that's right. upstream issue, see comment 13...

So if this doesn't work with gcc-4, shouldn't the ebuild depend on gcc-3? Because as it is, I installed gcc-3 so that I could install this and now gcc-3 isn't depended on by anything so when I run a script that tells me stuff to punt, it mentions gcc-3.

(In reply to comment #42) > It is only a build time dep hense it can be removed after installing qemu. Each ebuild does have "DEPEND" and "RDEPEND" variables, meaning compile-time and run-time dependencies. So, it "makes sense" to add gcc-3 to "DEPEND" variable. Unfortunately, last time I checked, portage treated both variables the same way.
(In reply to comment #41) > So if this doesn't work with gcc-4, shouldn't the ebuild depend on gcc-3? No. As a policy we don't depend on specific versions of gcc. Right now all we can do is check the gcc version you're building with and die if it's >=4.0, which we already do. Sorry. We're trying as best we can to get everything working with GCC 4, but in this case it's out of our hands. =/
