If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5fc84f8d1aad21935e39ef05f7d96408eb37697f Author: Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx> Date: Fri Nov 15 11:36:09 2019 +0000 libtraceevent: Fix lib installation with O= [ Upstream commit 587db8ebdac2c5eb3a8851e16b26f2e2711ab797 ] When we use 'O=' with make to build libtraceevent in a separate folder it fails to install libtraceevent.a and libtraceevent.so.1.1.0 with the error: INSTALL /home/sudip/linux/obj-trace/libtraceevent.a INSTALL /home/sudip/linux/obj-trace/libtraceevent.so.1.1.0 cp: cannot stat 'libtraceevent.a': No such file or directory Makefile:225: recipe for target 'install_lib' failed make: *** [install_lib] Error 1 I used the command: make O=../../../obj-trace DESTDIR=~/test prefix==/usr install It turns out libtraceevent Makefile, even though it builds in a separate folder, searches for libtraceevent.a and libtraceevent.so.1.1.0 in its source folder. So, add the 'OUTPUT' prefix to the source path so that 'make' looks for the files in the correct place.
