hi there,
thanks for working on getting the shared lib of libraries! I was
pointed to this work by Evan Martin as well and he pointed me to this
(http://codereview.chromium.org/88058). However I am having some
difficulty getting it to build and it errors out while building
libxml.

scons: building terminated because of errors.
===============================================
Here are the steps that I tried:
a) first I tried to download each patch from patch set 4 and patched
the corresponding files manually. Removed sconsbuild directory and
rebuilt. it had the same errors.
I read your instructions in Description section but I did not
understand where exactly I need to make changes to exclude and include
those files. I looked at all_main.scons and common.gypi. it would be
really helpful if you can elaborate on those instructions.
b) I did a get latest with revision 14166 by using following command:
CHROMIUM_ROOT$ gclient sync --revision s...@14166
(chromium root = directory that has src directory in it).
Let me know what steps I might be missing. Another point I want to add
is that I have followed the instructions in 'Staying Green more of the
time' section of getting code on chrome wiki for linux developers, if
that matters any.
Thanks,
