error: file /usr/bin/trace-cmd conflicts between attempted installs of kernelshark-1.2+git0+7055ffd37b-r3.core2_32 and trace-cmd-1.2+git0+7055ffd37b-r3.core2_32

Only found when MACHINE = "intel-core2-32" and PACKAGE_CLASSES = "package_rpm".
Changing MACHINE to "intel-corei7-64" or PACKAGE_CLASSES to "package_ipk" allows the build to complete successfully.
Comment 1 Darren Hart 2014-07-18 23:06:01 UTC 
Patch submitted to oe-core. The problem was that if you try to install both kernelshark and trace-cmd, they both have packaged trace-cmd. I can't explain why this only appeared on one machine for Cal, but this did reproduce for me on intel-corei7-64 too.

A simple fix is just to remove trace-cmd from the install prior to packaging. It is maybe a little crude, but it's simple and consistent with the current do_install() task which already removes the datadir.

I think this would be appropriate for daisy as well.
