[gentoo-user] Compiler error during qemu installation

[gentoo-user] Compiler error during qemu installation

[Wolfgang Liebich]

Hi,
I tried to install qemu on my system. The command I used (and the
response) were:

emerge -v --ask --tree --newuse qemu
>>> --newuse implies --update... adding --update to options.

These are the packages that would be merged, in reverse order:

Calculating dependencies... done!
[ebuild  N    ] app-emulation/qemu-0.8.0  0 kB
[ebuild  N    ]  app-emulation/qemu-softmmu-0.8.0  USE="kqemu -sdl" 77 kB
[ebuild  N    ]   app-emulation/kqemu-0.7.2  USE="-sdl" 1,310 kB
[ebuild  N    ]  app-emulation/qemu-user-0.8.0  0 kB


The compilation of qemu-user dies with the error msg

You need gcc 3.x to compile Qemu.

Hi,
+1 for gcc-3.X.
Just to add that maybe you'll have to use gcc-3.4.X for kernel 
compilation too, if you use "kqemu" USE-flag (as above).
I compile the 'kernel'+all of qemu with 3.4.X

No, you don't need GCC3 to compile _kqemu_. kqemu communicates with QEMU via 
device and may be compiled by different version of GCC. Works fine for me.

So GCC3 for QEMU and GCC4 for kqemu and kernel.

So how does one go about this?  Would emerge gcc-3.4.4 (or whatever the
version you want to use) do the trick?  Is there anything else that
would need to be done?  As in, would one need to tell the portage to use
the old compiler to build qemu, or would it just do it automatically?
Shouldn't the e-build depend on gcc 3.x?  Sorry for so many questions,
just trying to gain better understanding!

Hi,
GCC is SLOTed, you could have more than one/two versions at once.
Managed with 'gcc-config ...'. Check the options.
Check with "eix ^gcc$" to see all available versions, then run:
emerge =sys-devel/gcc-3.4.6-rX (depending on your arch/~arch).
Then play with 'gcc-config' to go back&forth (do "source /etc/profile" 
afterwards).
IIRC the ebuild (qemu-softmmu) gives out a warning if build with 4.X, 
check the ebuild.

Howdy, thanks for the reply!  I've followed the guide at
http://gentoo-wiki.com/HOWTO:_Qemu which kind of worked.  I wasn't able
to emerge "qemu", but I was able to emerge qemu-softmmu, which is all I
really needed (though I do sometimes like to play with other
architectures...)  Even using the 3.4.6 compiler, qemu-user complains
about libc as the original poster talked about.  Of course, all of this
is fixed in qemu-0.8.2 supposedly, but I prefer not to use ~x86 if I can
help it.  Thanks again!
