Qemu on FC4August 13, 2005Since upgrading to FC4 kqemu the, accelerator could not be used (since it's not compatible with the new kernel). That effectively means Qemu cannot be used at all because with out the accelerator the emulator is too painfully slow. Unfortunately attempting to recompile again did not work out because of an error. So I downloaded the latest version (0.71) and had another go but the error simply wouldn't go away.
/dev/shm/qemu-0.7.1/target-i386/ops_sse.h:574: error: unable to find a register to spill in class ‘GENERAL_REGS’
/dev/shm/qemu-0.7.1/target-i386/ops_sse.h:574: error: this is the insn:
(insn:HI 18 17 19 0 /dev/shm/qemu-0.7.1/target-i386/ops_sse.h:569 (set (strict_low_part (subreg:HI (reg/v:DI 63 [ r ]) 0))
(mem/s/j:HI (plus:SI (mult:SI (reg:SI 64)
(const_int 2 [0x2]))
(reg/v/f:SI 59 [ s ])) [0
Apparently this is a compatibility issue with GCC 4.0.0 which is the version that's included with Fedora Core 4. Someone suggested removing the the optimization flag, which I did only to run into another error: ./op.h:6382: error: ‘memcpy’ redeclared as different kind of symbol ./op.h:6383: error: called object ‘memcpy’ is not a function Then there was another suggestion about using the --cc=gcc32 now the previous error can no longer be seen, it's position has been taken up by something similar: /dev/shm/qemu-0.7.1/softmmu_header.h:100: can't find a register in class `GENERAL_REGS' while reloading `asm'
This is begining to be really annoying but fortunately a make clean did the trick.
