Description Miroslav Rezanina 2017-04-10 10:41:54 UTC

Description of problem:

When trying to build qemu-kvm package using brew, I'll get following error:

DEBUG util.py:257:  Error: Package: systemtap-devel-3.1-2.el7.s390 (build)
DEBUG util.py:257:             Requires: kernel-devel-uname-r

This issue is hit only on i686 or s390 architecture.

Comment 2 Frank Ch. Eigler 2017-04-10 12:59:42 UTC

Wondering why that package is requiring systemtap-devel.  Chances are you only need systemtap-sdt-devel (for the sys/sdt.h header).

As for kernel-devel-uname-r -- that is supposed to be a magic virtual resource provided by the kernel/rpm.  Not sure - do we even ship a s390 / i686 kernel?

I can check for this possibility.

Build has worked on this architectures. Hit this issue for last +- 7 days.

Comment 4 Miroslav Rezanina 2017-04-12 17:16:36 UTC

qemu-kvm is going te stop building 32bit packages so not needed anymore. However, as kernel packages are not build, package can't be installed on 32bit systems.

Comment 5 Frank Ch. Eigler 2017-04-12 18:07:26 UTC

qemu-kvm should build against systemtap-sdt-devel (and not systemtap or the stap binary).  The qemu configure file needs this change:

(or ... season to taste:)

  dtrace --help 2>/dev/null | grep -q systemtap
  if test $? -eq 0; then
    trace_backend_stap="yes"

RHEL 7 is 64-bit only. We should not need to install any packages on 32bit systems. Thanks.
