Cham-Crypto Implementation Problem

[balu...@gmail.com]

Hello,

I'm working in Attribute-Based Encryption.

I want to implement the scheme using Charm.

For that I have downloaded the Charm-Crypto-0.42 from the Charm Crypto site.

It requires the preambles : 1) Git

                                       2) Python 3.3.2

                                       3) m4

                                       4) libssl-dev

Since  I'm working in Ubuntu 12.04, the OS says that libssl-dev  and also for subversion already exits.

Moreover, I have installed PBC and GMP.

I have installed the above in the root ( Ubuntu 12.04, PBC, GMP, git or subversion, python 3.3.2, m4 and libssl-dev)  and

case 1:

 while configure charm(sudo .\configure.sh  --python=/usr/local/lib/python3.3), no problem. Whereas, while using the sudo make build command , it shows the 

make : execvp :  usr/local/lib/python3.3 permission denied, error 127 .

we also tried to release the access permission through chmod +777 for usr/local/lib/python3.3 , it shows the error.

the problem exists in distribute_setup.py file ( we change the permission option for this also)

case 2:

if configure using ./configure.sh alone, it shows the 

tar file.py couldn't open successfully  , error 1 comes.

Please provide a solution. 

with regards,

a.balu
