Bug 482878 – app-emulation/qemu-1.6.0 configure fails with USE="-fdt" and QEMU_SOFTMMU_TARGETS="arm"

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Mike Gilbert 2013-08-29 04:29:47 UTC]

Maybe this could be added to the REQUIRED_USE conditions?

ERROR: fdt disabled but some requested targets require it.
       You can turn off fdt only if you also disable all the system emulation
       targets which need it (by specifying a cut down --target-list).

Same here:

USE="-fdt"
QEMU_SOFTMMU_TARGETS="arm i386 ppc x86_64"
QEMU_USER_TARGETS="arm i386 ppc x86_64"

Results in:

 * Building the following softmmu targets: ,i386-softmmu,x86_64-softmmu,arm-softmmu,ppc-softmmu
 * Building the following user targets: ,i386-linux-user,x86_64-linux-user,arm-linux-user,ppc-linux-user
 * ./configure --prefix=/usr --sysconfdir=/etc --libdir=/usr/lib64 --docdir=/usr/share/doc/qemu-1.6.0/html --disable-bsd-user --disable-guest-agent --disable-strip --disable-werror --python=/usr/bin/python2.7 --disable-linux-user --enable-system --with-system-pixman --target-list=,i386-softmmu,x86_64-softmmu,arm-softmmu,ppc-softmmu --disable-bluez --enable-gtk --with-gtkabi=3.0 --enable-sdl --enable-linux-aio --disable-brlapi --disable-cap-ng --disable-curl --disable-fdt --disable-glusterfs --disable-libiscsi --enable-vnc-jpeg --enable-kvm --enable-curses --enable-glx --enable-vnc-png --disable-rbd --disable-vnc-sasl --disable-seccomp --disable-smartcard-nss --disable-spice --disable-vnc-tls --disable-vnc-ws --disable-usb-redir --enable-uuid --disable-vde --enable-vhost-net --disable-virtfs --enable-vnc --enable-attr --disable-xen --disable-xen-pci-passthrough --disable-xfsctl --audio-drv-list=sdl,alsa,oss --enable-migration-from-qemu-kvm --disable-debug-info --disable-debug-tcg --enable-docs --disable-tcg-interpreter

confirm

Created attachment 357670 [details, diff]
Ebuild patch

Here is a patch to enable fdt via IUSE defaults, and add required use constraints for the relevant targets (based on configure).

Let me know if it is ok to apply one or both changes.

Applied to 1.6.0, thanks.
