We already have a page pretty similiar to this here:

  https://wiki.linaro.org/Mentoring/ToolchainInstall

We should probably merge the best parts of each into one page and make
sure it has the "CategoryHowTo" at the bottom.

I think you have the right idea. However, my version of
arch/arm/mach-omap2/Makefile includes it:

  AFLAGS_omap-headsmp.o  :=-Wa,-march=armv7-a$(plus_sec)

Does your version have this?

Hello doanac,

chandrakala  has just
posted a new question on Ask Linaro, entitled problem in installing
Linaro tools

and tagged "/linaro  installation
/". Here's what it says:

Hi all,

Iam new to linux and gnu tools. i have downloaded linaro gnu tools
to install cortex-a8 on my ubuntu machine. iam able to successfully
install gcc tools. But when i try to install arm tools it is
throwing error. following are the commands used to install gnu tools
and the error it is generated

mckala@mckala:~/Desktop/gstreamer/gcc_objdir$
../gcc-linaro-4.6-2011.12/gcc-linaro-4.6-2011.12/configure
--target=arm-*-elf --disable-bootstrap --enable-languages=c,c++
--with-mode=thumb --with-arch=armv7-a --with-tune=cortex-a8
--with-fpu=neon --with-float=softfp
--prefix=/home/mckala/Desktop/gstreamer/gcc_objdir --disable-werror
--with-newlib

mckala@mckala:~/Desktop/gstreamer/gcc_objdir$ make all-host

mckala@mckala:~/Desktop/gstreamer/gcc_objdir$ make install-host

with this gnu tools installation is completed and i did not get any
error. when i used the following command to install cross compiler,
it is giving error

mckala@mckala:~/Desktop/gstreamer/gcc_objdir$ make

The error is

checking for suffix of object files... configure: error: in
|/home/mckala/Desktop/gstreamer/gcc_objdir/arm-*-elf/libgcc':
configure: error: cannot compute suffix of object files: cannot
compile See|config.log' for more details. make[1]: ***
[configure-target-libgcc] Error 1

config.log file is showing the following error.

gcc_objdir/arm-/-elf/bin/
-B/home/mckala/Desktop/gstreamer/gcc_objdir/arm-/-elf/lib/ -isystem
/home/mckala/Desktop/gstreamer/gcc_objdir/arm-/-elf/include -isystem
/home/mckala/Desktop/gstreamer/gcc_objdir/arm-/-elf/sys-include -V >&5

xgcc: fatal error: no input files compilation terminated.

Can any one please help on this.

Thanks in advance.

Its hard to say without more details like where you got your kernel,
what config you built with, and what platform you are running on.
However, the two most common errors I've encountered when people see the
message you pasted are:

1) you don't have your "console" variable set properly in u-boot. For
example, my OMAP devices default to "console=ttyS2,115200n8". However,
it needs to be "console=ttyO2,115200n8"

2) you built your kernel with/without device tree and u-boot is
launching your kernel without/with device tree.

ci.linaro.org  is more appropriate.


people.linaro.org  was recommended by Dave,
probably for the general purpose + cron jobs.

But if ci.linaro.org  is more appropriate, I might
ask that, too.


That was probably a bad recommendation by me. I thought you were just 
wanting some one-off job for personal interest. In that case a cron job 
would work. However, if you have something more official then Fathi is 
right - you should use ci.linaro.org.
