Reasons :

1- You have exported wrong path to your toolchain bin folder
2- Your toolchain executables have not suitable permission
3- You are using this toolchain on a 32 bit system
4- You are using old distro (or old libc)

1- hf stands for hardware floating points , it means gcc will accelerate floating point operations with hardware floating point processing unit instead of simulating them with cpu. It has absolutely no effect on kernel performance because kernel uses it's own way to deal with floating points but it can improve performance on executable files compiled by this option.

2- Try changing CFLAGS and if not works then you should use -Wall and check all warnings and find where issue comes from. Also you should use UART and monitor logs (if you can setup UART interface)

That was all I could help you.

Hi.
Hopefully this isn't too far off topic. This is the clearest toolchain building thread I've found though.
I successfully followed your instructions to build bare metal linaro 4.7, 4.8 and 4.9 targeted to armv6k
But I can't find anything that works for arm-linux-androideabi- toolchain.
Linaro official repo and other versions I've tried all crash my terminal running build-linaro.sh before any output, but android build system and ct-ng for bare metal toolchain all work fine.
Maybe system issue? Ubuntu 13.04 64 bit.
I'd welcome any suggestions.
Using armv7 and newer linaro toolchains Bork my Rom builds even with the correct cflags for armv6k.
I've read that the toolchain incorporates parts of its own code when compiling and that's why I need a new toolchain built for legacy chipset. Or I'm stuck with 4.7 which was the last official linaro release which supported under armv7.

Looks like general compilation errors man, not the place to find answers here really. Just a heads up

Did you read it? :)
Unused variable means there's a variable there, that's not used ;)

So either put -wno-unused-variables (off the top of my head, google will know, the point here is it sees unused variables but tells the compiler to not care)
Or you can remove the variables from those

It's "maybe uninitialized variables" not "unused variable" . They are totally different.

Also, You should not remove all unused variables, it may cause some problems.

Don't edit/remove anything from source. You just have to edit Makefile. Since Makefile's are different it's hard to tell you what to do without seeing the Makefile, so you should put your makefile here then we can help you more easier.

Uninitialized is completely different to unused.

Uninitialized-> not initialized yet so need to be initialized

Unused--> defined but not not used ever so it can be removed, since it's not needed

Is my understanding wrong? Thanks, sorry for going off topic

Edit: seems we are both right.. there are uninitialized and unused variables in the post

As alireza has stated you also need the no uninitialized variables

It's better to actually fix the problems, but hiding them in the makefile will do :p you'll see in my kernel source for HTC One that these issues are fixed rather than masked

    The toolchains with arm-cortex_a15-linux-gnueabihf prefix are optimized for Cortex-A15 cpu with Neon-VFPv4 technology support.
    The toolchains with arm-cortex_a9-linux-gnueabihf prefix are optimized for Cortex-A9 cpu with Neon-VFPv3 technology support.
    The toolchains with arm-cortex_a8-linux-gnueabi prefix are optimized for Cortex-A8 cpu with Neon-VFPv3 technology support (these are ideally suited for our Samsung S Plus).
    The toolchains with arm-cortex_a7-linux-gnueabihf prefix are optimized for Cortex-A7 cpu with Neon-VFPv4 technology support.
    The toolchains with arm-cortex-linux-gnueabi, arm-linux-gnueabi or arm-unknown-linux-gnueabi prefix are built for generic Cortex-A cpu and configured with similar settings to those of the latest Linaro toolchains, the tools and libraries inside them are built with Thumb-2 (for architecture) and VFPv3-D16 (for fpu) instruction sets support.
    VFPv3-D16 has been chosen to also support nVidia Tegra2, Marvell Dove cpu and other cpu with half-precision FP format, consider it as a common denominator.
    These generic toolchain builds shouldn't work on a cpu which has ARMv4T or ARMv5 architecture.

    I hope you find them useful...
    Let me know.
    Thanks!

    HOW TO: Build your customized Cross Compiler Toolchain​

    This is a guide to make a custom build of your toolchain on Ubuntu Linux (I use version 12.10 and 13.04, but should also fit on 12.04).

    1) Open the terminal, install the following packages (I hope the list is complete, let me know if something is missing):
    Code: 
    sudo apt-get install mercurial mercurial-common flex bison gperf ncurses-dev texinfo gcc g++ \
autoconf automake libtool gawk patch autotools-dev libsigsegv2 libmpfr-dev libgmp-dev \
libltdl-dev libgmpxx4ldbl libmpc-dev expat libexpat1-dev libpython3.3 libpython3.3-stdlib \
libssl-dev libssl-dev zlib1g-dev subversion

    2A) Clone my customized CrossTool-NG repository
    For latest builds:
    Code: 
    git clone https://github.com/Christopher83/crosstool-ng.git
    For 2014 builds:
    Code: 
    git clone https://github.com/Christopher83/linaro_crosstool-ng.git
    OR 2B) Clone Linaro CrossTool-NG repository
    Code: 
    bzr branch lp:~linaro-toolchain-dev/crosstool-ng/linaro crosstool-ng
    OR 2C) Clone Standard CrossTool-NG repository
    Code: 
    hg clone http://crosstool-ng.org/hg/crosstool-ng

    3) If you chose 2B or 2C, download, if you wish, the compressed archive containing my configuration files
    and unzip it inside the folder crosstool-ng/samples (note: crosstool-ng is the folder of the builder sources you previously cloned)

    4) Configure the folder where you would like to install the builder script (replace /crosstool-ng_install_path with the absolute path you prefer):
    Code: 
    cd crosstool-ng
./bootstrap # If present, it's needed only for some versions of crosstool-NG
./configure --prefix=[I]/crosstool-ng_install_path[/I]

    5) Build the sources and install the builder:
    Code: 
    make
make install

    Within your target folder /crosstool-ng_install_path you will find a new folder named bin with only an executable script named ct-ng

    Edit your .bashrc
    Code: 
    gedit ~/.bashrc

    and add, at the bottom of the file, the reference to the installation location of the builder /crosstool-ng_install_path
    Code: 
    export PATH=${PATH}:[I]/crosstool-ng_install_path[/I]

    6) You should be ready, try running these commands
    Display the script help
    Code: 
    ct-ng help

    View the list of samples configurations
    Code: 
    ct-ng list-samples

    Display the information about a sample configuration
    Code: 
    ct-ng show [I]config_name[/I]

    7) Now proceed with the configuration of your toolchain
    7A) Starting from a default configuration file sample
    Code: 
    ct-ng arm-unknown-linux-gnueabi
ct-ng menuconfig

    Remember to enable debugging, so if something goes wrong you can restart from the last successfull step
    Code: 
    Paths and misc options  --->
(*) Debug crosstool-NG
( )   Pause between every steps
(*)   Save intermediate steps
(*)     gzip saved states

    7B) Starting from one of my configurations you can find inside the samples package
    Code: 
    ct-ng [I]chosen_configuration_name[/I]
ct-ng menuconfig

    If the GCC version or the Linux version is not ready also after the sync of ct_ng repo, you have to temporarly edit the files:
    - config/cc/gcc.in
    - config/kernel/linux.in
    The same may be necessary for the other tools.

    8) Build your toolchain (replace the 4 with the number of parallel jobs that you want, based on your number of cores)
    Code: 
    ct-ng build.4

    The build process takes a long time, depending on your network speed (you need to download all the source packages of the tools and libraries of the toolchain) and on your PC configuration.

    NOTE:
    If the build fails, write down the last step was successful, check the error message and correct the configuration or install any missing package.
    You can get a list of the steps that can be used by running
    Code: 
    ct-ng list-steps

    After resolving the problem, you can restore the build simply running (replace last_successfull_step with your successfull built step)
    Code: 
    ct-ng [I]last_successfull_step[/I]+
    The + after the name of the step means "restart from the step after the one indicated"
    Click to expand...
    Click to collapse
    I hope I'm not missing anything.
    Let me know...

    HOW TO: Use a toolchain for your kernel builds​

    - Download the compressed file of your preferred toolchain
    - Uncompress the file inside your toolchains folder
    - Open a terminal
    - Change dir to your kernel sources path
    Code: 
     cd [I]/YOUR_KERNEL_SOURCES_PATH[/I]
    where /YOUR_KERNEL_SOURCES_PATH is the path where you have cloned the kernel sources repository

    - Export the required architecture and cross compiler toolchain path for the next build commands
    Code: 
     export ARCH=arm
 export CROSS_COMPILE=[I]/YOUR_TOOLCHAINS_PATH[/I]/[I]TOOLCHAIN_FOLDER_NAME[/I]/bin/[I]TOOLCHAIN_PREFIX[/I]-
    where
    /YOUR_TOOLCHAINS_PATH is the path where you have extracted the compressed toolchain (eg. /opt/toolchains)
    TOOLCHAIN_FOLDER_NAME is the name of the toolchain folder previously uncompressed (eg. arm-cortex_a8-linux-gnueabi-linaro_4.7.3-2013.02)
    TOOLCHAIN_PREFIX- is the prefix of the chosen toolchain (eg. arm-cortex_a8-linux-gnueabi- or arm-unknown-linux-gnueabi- or, for the builds released from 16/02/2013, simply arm-gnueabi-)

    - Clean the output of your previous build
    Code: 
    make clean
    - Configure your kernel build
    Code: 
     # If is the first build
 make your_device_defconfig
 # If you want to change some kernel configuration options
 make menuconfig

    - Build your kernel
    Code: 
     make -j5
    Replace make -j5 according to your pc configuration (-j5 uses 5 parallel build jobs and is suitable for a quad core cpu)
