With USE=fdt, app-emulation/qemu-1.1.1-r1 fails to build:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.4/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.4/../../../../lib64/libfdt.a(fdt.o): relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.4/../../../../lib64/libfdt.a: could not read symbols: Bad value

This is apparently because sys-apps/dtc-1.2.0 (the current stable version, and
the minimum version required by the qemu ebuild) does not install a shared
libfdt.  Updating to dtc-1.3.0 would solve the problem, as it installs the
shared library, but stable versions of qemu should work with stable dtc.

[Comment 1 Doug Goldstein (RETIRED) 2012-10-26 22:10:05 UTC]

The bug here is with sys-apps/dtc. Its not built with -fPIC and needs to be. Unfortunately I'm not near a Gentoo box atm so reassigning to bug-wranglers to assign this correctly.

[Comment 2 Samuli Suominen (RETIRED) 2012-10-27 18:07:08 UTC]

so lets just stabilize newer dtc? any objections from ppc maintainers?

[Comment 3 Andreas Thalhammer 2012-11-01 08:23:34 UTC]

I've just hit this bug. It took me a while to find that the actual fault is with dtc (libfdt) rather than with qemu.

NOTE that the QEMU_SOFTMMU_TARGETS x86, x86_64 and m68k worked fine without errors.

I recently added the QEMU_SOFTMMU_TARGETS arm, ppc, ppc64 and ppcemb, and all of them where affected by sys-apps/dtc-1.2.0 not being compiled with -fPIC.

SOLUTION was to add -fPIC to C[XX]FLAFS globally for the emerge of dtc. qemu compiled without errors thereafter.

This really should be fixed in sys-apps/dtc. Other users may be affected as well and they may also have a hard time finding the actual cause...

this is not helpful. try the latest ~arch marked dtc from tree and report back if that works. if you read the bug, we are aiming for stabilizing new version to solve this after verification(s).

sys-apps/dtc-1.3.0 conflicts with media-libs/freetype-2.4.9-r1, which is pulled by ~46 packages; some of them, like xorg-server and kdelibs, I consider too important to play with.

The conflict is a file collision, namely /usr/bin/ftdump.

Can I safely upgrade to media-libs/freetype-2.4.10-r1 and keep the system in a working state? Will this solve the file collision?

[Comment 6 Samuli Suominen (RETIRED) 2012-11-03 19:24:36 UTC]

should be fixed in tree now in 1.3.0 and 9999

[Comment 7 Andreas Thalhammer 2012-11-04 11:50:24 UTC]

I can now confirm that this is fixed for me on amd64 with stable sys-apps/dtc-1.3.0 and app-emulation/qemu-1.1.2-r2,
