binutils starting at least from 2.23 when build for target require uClibc configured with UCLIBC_HAS_WCHAR otherwise: libtool: link: [...] -o as-new [...] read.o: In function `read_symbol_name': read.c:(.text+0x3634): undefined reference to `mbstowcs' collect2: error: ld returned 1 exit status because "mbstowcs" is not available in the C library. Even though we're not yet using 2.23.2 as the default version, we will probably do it in the near future, so this commit doesn't bother with making the wchar dependency version-specific, and applies it to the binutils package as a whole. Fixes bug #6218 [Thomas: - more details in the commit log. - add comment about the wchar dependency - propagate the dependency to dropwatch (and fix a mistake in the architecture dependencies of the comment) - propagate the dependency to oprofile.] Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Anton Kolesov <akolesov@synopsys.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Reviewed-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>

OProfile is a system-wide profiler for Linux systems,
|
|
capable of profiling all running code at low overhead.
|
|
OProfile is released under the GNU GPL.
|
|
|
|
It consists of a kernel driver and a daemon for collecting
|
|
sample data, and several post-profiling tools for turning
|
|
data into information.
|
|
|
|
OProfile leverages the hardware performance counters of the
|
|
CPU to enable profiling of a wide variety of interesting
|
|
statistics, which can also be used for basic time-spent
|
|
profiling. All code is profiled: hardware and software
|
|
interrupt handlers, kernel modules, the kernel, shared
|
|
libraries, and applications.
