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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
