# TODO:
# - wait till the gcc bug http://gcc.gnu.org/PR16185 is fixed.
#
# Conditional build:
%bcond_without	kqemu			# disable KQEMU ACCELERATOR support in QEMU
%bcond_with	cflags_passing		# with passing rpmcflags to Makefiles
%bcond_with	dosguest		# add special patch when use with DOS as guest os
%bcond_with	nosdlgui		# do not use SDL gui (use X11 instead)
# Note that gcc4 build is very problematic and not supported by qemu team
%bcond_without	gcc4			# use gcc4 patches (broke build on gcc33)
%bcond_without	dist_kernel		# without distribution kernel
%bcond_without	kernel			# build kqemu KERNEL MODULES
%bcond_without	userspace		# don't build userspace
#

# no kqemu for ppc

%description
QEMU is a FAST! processor emulator. By using dynamic translation it
achieves a reasonnable speed while being easy to port on new host
CPUs. QEMU has two operating modes:

- User mode emulation. In this mode, QEMU can launch Linux processes
  compiled for one CPU on another CPU. Linux system calls are converted
  because of endianness and 32/64 bit mismatches. Wine (Windows
  emulation) and DOSEMU (DOS emulation) are the main targets for QEMU.

- Full system emulation. In this mode, QEMU emulates a full system,
  including a processor and various peripherials. It can also be used to
  provide virtual hosting of several virtual PC on a single server.

%description -l pl.UTF-8
QEMU to szybki(!) emulator procesora. Poprzez użycie dynamicznego
tłumaczenia osiąga rozsądną szybkość i jest łatwy do przeportowania,
aby działał na kolejnych procesorach. QEMU ma dwa tryby pracy:

- Emulacja trybu użytkownika. W tym trybie QEMU może uruchamiać
  procesy linuksowe skompilowane dla jednego procesora na innym
  procesorze. Linuksowe wywołania systemowe są tłumaczone ze względu na
  niezgodność kolejności bajtów w słowie i 32/64-bitowego rozmiaru
  słowa. Wine (emulacja Windows) i DOSEMU (emulacja DOS-a) to główne
  cele QEMU.

- Pełna emulacja systemu. W tym trybie QEMU emuluje cały system,
  włączając w to procesor i różne urządzenia peryferyjne. Może być także
  używane do wirtualnego hostowania kilku wirtualnych pecetów na
  pojedynczym serwerze.
