RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jes Sorensen 2011-02-02 15:04:11 UTC

Description of problem:
Current rhel6-qemu-kvm fails to build when one does not specify --enable-spice
due to dummy wrapper macros returning a value. This fails when the macro
is called without storing the return value.

Looks like commit 1c6074d107dff93c7c7b0edfb5da871504802946 added a dependency on spice.  That wasn't intentional.  Scheduling to fix for 6.3.

Hi,Gerd

   Would you please tell me your plan?as you mentioned,you patch added a dependency on spice.do you plan to revert this patch or reserve this patch?
Would you please tell us in details?

Comment 14 Gerd Hoffmann 2011-10-10 08:37:05 UTC

Plan is to apply a patch which #ifdefs the spice bits with CONFIG_SPICE so no spice functions are called in case spice is disabled at compile time.

Comment 16 Gerd Hoffmann 2012-02-17 09:46:29 UTC

patch posted.

Comment 19 Chao Yang 2012-03-06 10:15:18 UTC

Verified this issue by the steps below:
1. git clone the latest qemu-kvm-rhel6 source code from ehabkost's tree
2. ./configure --disable-spice  --enable-werror
3. make && make install

Actual Result:
No spice related warning or error prompts, qemu-system-x86_64 is installed correctly. 
So, this issue has been fixed.
