In ubuntu systems the libaudit test was always failing due to the
newline in the printf call not being escaped, which somehow didn't
prevented the test from working as expected on other systems, such
as fedora18.
Fix it by removing the newline, as this is just a test, that program is
just a compile test.
The error messages, obtained using 'make V=1':
CHK libaudit
<stdin>: In function ‘main’:
<stdin>:5:9: error: missing terminating " character [-Werror]
<stdin>:5:2: error: missing terminating " character
<stdin>:6:1: error: missing terminating " character [-Werror]

cc1: all warnings being treated as errors
config/Makefile:241: No libaudit.h found, disables 'trace' tool, please install audit-libs-devel or libaudit-dev
After this change the test works as expected in all systems tested and the
'trace' tool is built when the needed devel packages are installed.

Since libelf sometimes uses libpthread, we have to list that after -lelf
when someone tries to build statically. Else things go boom:
Makefile:479: *** No libelf.h/libelf found, please install \

Among other things, the following:
commit 31160d7fea
Date: Tue Jan 8 16:22:36 2013 -0500
perf tools: Fix GNU make v3.80 compatibility issue
attempts to aid the user by tapping into an existing error message,
as described in the commit message:
... Also fix an issue where _get_attempt was called with only
one argument. This prevented the error message from printing
the name of the variable that can be used to fix the problem.
or more precisely:
-$(if $($(1)),$(call _ge_attempt,$($(1)),$(1)),$(call _ge_attempt,$(2)))
+$(if $($(1)),$(call _ge_attempt,$($(1)),$(1)),$(call _ge_attempt,$(2),$(1)))
However, The "missing" argument was in fact missing on purpose; it's
absence is a signal that the error message should be skipped, because
the failure would be due to the default value, not any user-supplied
value. This can be seen in how `_ge_attempt' uses `gea_err' (in the
config/utilities.mak file):
_ge_attempt = $(if $(get-executable),$(get-executable),$(_gea_warn)$(call _gea_err,$(2)))
_gea_warn = $(warning The path '$(1)' is not executable.)
_gea_err = $(if $(1),$(error Please set '$(1)' appropriately))
That is, because the argument is no longer missing, the value `$(1)'
(associated with `_gea_err') always evaluates to true, thus always
triggering the error condition that is meant to be reserved for
only the case when a user explicitly supplies an invalid value.
Concretely, the result is a regression in the Makefile's configuration
of python support; rather than gracefully disable support when the
relevant executables cannot be found according to default values, the
build process halts in error as though the user explicitly supplied
the values.
This new commit simply reverts the offending one-line change.

According to Documentation/Changes, the kernel should be buildable with
GNU make 3.80+. tools/perf/config/utilities.mak contains the "$(or"
construct, which requires make 3.81. This causes "make" to fail on
systems with GNU make 3.80.
Replace "$(or" with an equivalent "$(if" expression, to restore backward
compatibility. Also fix an issue where _get_attempt was called with only
one argument. This prevented the error message from printing the name of

For cross-compiling on Android, some specific changes are needed in

Update the Makefile to support cross-compiling for Android.
The original ideea for this was send by Bernhard Rosenkraenzer in
https://lkml.org/lkml/2012/8/23/316, but this is a rewrite.
Changes:
() support bionic in addition to glibc
() remove rt and pthread libraries that do not exist in Android
() use $(CFLAGS) when detecting initial compiler flags. This is needed
when setting CFLAGS as an argument of make (e.g. for setting --sysroot).
() include perf's local directory when building for Android to be able to find
relative paths if using --sysroot (e.g.: ../../include/linux/perf_event.h)

Add a compile-time option (NO_BACKTRACE) to enable or disable

since it offers the possibility to turn on/off printing the backtrace.

This patch adds a simple GTK2-based browser to 'perf report' that's
based on the TTY-based browser in builtin-report.c.
To launch "perf report" using the new GTK interface just type:
$ perf report --gtk
The interface is somewhat limited in features at the moment:
- No callgraph support
- No KVM guest profiling support
- No color coding for percentages
- No sorting from the UI
- ..and many, many more!
That said, I think this patch a reasonable start to build future features on.

Currently, Python 3 is not supported by perf's code; this
can cause the build to fail for systems that have Python 3
installed as the default python:
python{,-config}
The Correct Solution is to write compatibility code so that
Python 3 works out-of-the-box.
However, users often have an ancillary Python 2 installed:
python2{,-config}
Therefore, a quick fix is to allow the user to specify those
ancillary paths as the python binaries that Makefile should
use, thereby avoiding Python 3 altogether; as an added benefit,
the Python binaries may be installed in non-standard locations
without the need for updating any PATH variable.
This commit adds the ability to set PYTHON and/or PYTHON_CONFIG
either as environment variables or as make variables on the
command line; the paths may be relative, and usually only PYTHON
is necessary in order for PYTHON_CONFIG to be defined implicitly.
Some rudimentary error checking is performed when the user
explicitly specifies a value for any of these variables.
In addition, this commit introduces significantly robust makefile
infrastructure for working with paths and communicating with the
shell; it's currently only used for handling Python, but I hope
it will prove useful in refactoring the makefiles.
