[ltt-dev] problem with patches for 2.6.29

Wed Jan 19 21:49:20 EST 2011

Hello Mathieu and all,

Thanks for your response Mathieu,

I  also guess that may be ltt-control is not installing properly on my  target 
system.. I am attaching the files, are log files of my  commands on ltt-control 
.

I am using a toolchain for cross compiling  (4.2.2-eabi) 

#   CC=arm-unknown-linux-gnueabi-gcc ./configure  
--prefix=/directory/path/for/installing/lttcontrols/ 
--host=arm-unknown-linux-gnueabi  --build=i686-pc-linux-gnu

than
#  make 
#  make install 

I am not so good with cross compiling; this is first time i am using it.. I have 
doubt that I am on mistake here.

thanks for helping..

Weird. Make sure you have a clean tree before you apply the patchset.

ltt-armall.sh is distributed with ltt-control. Maybe your make install
did not install it, and you might want to copy it by hand to your
target.
