Here is the error during binutil compilation:

In the guide it was written:
./configure --target=arm-linux --host= linux --build=i686 --without-gettext \
--without-intl --prefix=$SRCBLD/lib

But actually host "linux" wasn't recognized, so I set arm-linux instead...

Subject: Latest Oprofile on Android

Hello,

After playing a little with oprofile on freescale board with android 4.2.2, I \
discovered that there were many issues. By looking a little more, I discovered that \
the version provided by Android seems to be v0.9.1.

Since I am using an ARM cortex A9, and problems were reported I thought that it would \
be better to get the latest version of Oprofile.

However I can't seem to be able to build it successfully.

Is there a good step-by-step guide on how to achieve this?
Or would it be possible to integrate the latest version in the android build?

I tried to follow this guide
http://www.cnx-software.com/2010/03/25/profiling-in-embedded-systems-with-o-profile/

But I had errors during compilation, and in the end I am afraid that I will need a \
newer version of the kernel module also to enable oprofile.

Has anyone used a recent version successfully on Android, and could point me to the \
right steps?

Florian Girault
