[BitVisor-devel-en:14] Regarding Bitvisor compilation.

[Dushmanta Mohapatra]

I am Dushmanta , a CS PhD student at Georgia Institute of Technology,
Atlanta, US.
For one of my projects I am looking into Bitvisor details.

But I am facing some issue with its compiling (Bitvisor 1.1.1). I am
following the bitvisor1.1 manual
found at http://www.bitvisor.org/ . I hope you would be kind enough to help
me with that.

I can compile the elf image, but when I  try to compile the configuration
data
(password login related module1.bin,module2bin), I get some errors.
I use the default configurations and do not change anything in the
configuration files
(bitvisor.conf.tmpl)

I have a recent Thinkpad T520 (quad core Intel i5) and my base OS is Ubuntu
11.04 (64bit).
I have installed the necessary libraries (gcc, binutils, make, libssl-dev,
libusb-dev etc). I am not sure
what the issue is. My guess is, it might be related to binutils. Do I need
to compile it in a 32bit OS?
Do I need any cross compiler or gcc-multilib installed in my system?

Here are just some print outs from the compilation process. Please let me
know if you need any more
details.
