Category: qemu Group: None >Status: Closed >Resolution: Works For Me Priority: 5 Private: No Submitted By: Jana Delego (janado) Assigned to: Anthony Liguori (aliguori) Summary: compiling problem with "tcg_ctx" Initial Comment: When compiling kvm using the "--disable-cpu-emulation" flag on a 64 bit Intel Ubuntu, the compiler aborts with error "undefined reference to tcg_ctx", This problem exists since kvm-70. ---------------------------------------------------------------------- >Comment By: Jes Sorensen (jessorensen) Date: 2010-06-25 18:10 Message: upstream qemu-kvm builds and boots fine with --disable-cpu-emulation now. Closing Jes ---------------------------------------------------------------------- Comment By: Avi Kivity (avik) Date: 2008-10-02 16:05 Message: Well, it would be nice to support --disable-cpu-emulation, for example if you're worried about tcg security holes or tcg performance. ---------------------------------------------------------------------- Comment By: Anthony Liguori (aliguori) Date: 2008-09-29 15:56 Message: --disable-cpu-emulation should not be used with x86. It only exists as an ugly hack because ia64 doesn't support TCG. ---------------------------------------------------------------------- Comment By: Shen Okinudo (okinu) Date: 2008-09-29 03:37 Message: This bug persists in kvm-76 ---------------------------------------------------------------------- Comment By: Marshal Newrock (freedombi) Date: 2008-09-02 01:40 Message: Logged In: YES user_id=2201280 Originator: NO This seems to work with kvm-74. The patch allowed compilation, and the guest appears to be running well. ---------------------------------------------------------------------- Comment By: Amit Shah (amitshah) Date: 2008-08-29 11:59 Message: Logged In: YES user_id=201894 Originator: NO I'm not sure if this will make qemu work properly, but it fixes the build (also attached).
