* Setup 64 bit centos-5 and suse-10 chroots for testing binary
tarballs, and used them to verify the Cbuildv2 produced ones
compile 'Hello World!", and run on a real target.
* Got remote chromebook testing working in TCWG build farm.

* Did build and test run on aarch64 APM board of GCC
linaro-4.8-branch.
* Changed Cbuildv2 to disable parallel make jobs when building GCC
native on ARM or AARCH64 platforms, as the hardware can't handle
the load.
* Got the LSB tools installed and researched what they do.
* Debugged why 32 bit binary tarballs made in a chroot won't run
when installed on multiple x86_64 systems. Works now by statically
linking everything.

functional yet (running in the Foundation model currently); getting

Section 7.1.3, whose sub-sections include: "Implementation of malloc()
and free()", "Tools and libraries for malloc debugging", and
"Controlling and monitoring the malloc package", of Michael Kerrisk's
"The Linux Programming Interface" (http://man7.org/tlpi/index.html) is
one of the better reads of which I'm aware. He recommends reading the
man pages for malloc_info, malloc_stats, mallopt, and mallinfo (among
others) for more information.
In the C language, reclamation of allocated memory is usually driven
by the application. When you free() some memory, internal structures
know the size of what was previously allocated at the given location
(i.e. what was given to you by malloc()) and simply release that back
into the heap. There are ways to tweak the allocation of memory.

Subject: condition_variable_any missing from libstdc
To: linaro-toolchain(a)lists.linaro.org
Hi,
I sent this message a week ago but I don't think I was subscribed to the
list correctly. Apologies if it is repeated (it doesn't show in the
archive).
I have a problem with my cross build of (Linaro GCC 4.8-2013.10). I get the
following runtime linker errors regarding condition_variable_any:
"relocation error: /usr/local/lib/librobolib.so: symbol
_ZNSt22condition_variable_anyC1Ev, version GLIBCXX_3.4.11 not defined in
file libstdc++.so.6 with link time reference"
If I examine my built version of libstdc with readelf I get the following
output:
$ readelf -s ./src/.libs/libstdc++.so.6 | grep condition
10383: 000c58d8 68 FUNC LOCAL DEFAULT 11 _ZNSt15error_conditionC1E
10818: 000c58d8 68 FUNC LOCAL DEFAULT 11 _ZNSt15error_conditionC2E

10942: 000c591c 40 FUNC LOCAL DEFAULT 11 _ZNKSt15error_condition5v
Where as with the apt-get installed 4.6 version of the toolchain shows:
$ readelf -s /usr/arm-linux-gnueabi/lib/libstdc++.so.6 | grep condition
777: 000523b1 12 FUNC GLOBAL DEFAULT 12

_ZNSt18condition_variable@@GLIBCXX_3.4.11
(Which is still missing anything to do with condition_variable_any, but
given that my native 4.8 compiler doesn't contain this symbol either and my
code builds and runs natively, I assume this is how it should be).
Here is my build's version information:
$ arm-linux-gnueabi-gcc -v
Using built-in specs.
COLLECT_GCC=arm-linux-gnueabi-gcc
COLLECT_LTO_WRAPPER=/home/mark/arm-linux-gnueabi-4.8.2/libexec/gcc/arm-linux-gnueabi/4.8.2/lto-wrapper

Thread model: posix
gcc version 4.8.2 20131014 (prerelease) (Linaro GCC 4.8-2013.10)
I configured libstdc++-v3 respectively as follows:
$ ../gcc-linaro-4.8-2013.10/libstdc++-v3/configure --host=arm-linux-gnueabi
--prefix=/home/mark/arm-linux-gnueabi-4.8.2/ --enable-multilib
--enable-shared --disable-nls --disable-libstdcxx-pch
--enable-libstdcxx-threads --enable-libstdcxx-time
I assumed the relevant entries to enable C++11 threading and condition
variables etc would have been --enable-libstdcxx-threads
--enable-libstdcxx-time. I must be missing some other options or have done
something else wrong. Any suggestions?
thanks,
Mark

Hi, All
Under this site
http://releases.linaro.org/13.09/components/toolchain/binaries/,
there are many files released. but do we have any description on the file
naming rules?
Sorry for my simple question, I just want to know what the files are used
for. which one I should select when I need to use toolchain.
Like the files below, I can guess that aarch64 means that it will generate
files run on aarch64 platform, but I can not guess what's the difference
between linux and none, and not know what's the difference between gnu and
elf.
So if you have any wiki/link about the the naming rules or description
about the file,
please share me.

Hi toolchain gurus,
I am about to start some projects working with CortexMx devices and am
wondering if anyone has an opinion on which toolchain(s) I should
use/investigate?
Being a fan of Linaro, my first instinct would be to use cbuild2 to
build an arm-none-eabi- toolchain from a 4.8.x tree. But looking
around I can't help notice https://launchpad.net/gcc-arm-embedded.
Does anyone know if gcc-arm-embedded has things the Linaro toolchain
doesn't wrt Cortex M0, M3, and M4 device/instruction support?
Best regards,
Trevor
