Platform Install Manual — Charm-Crypto 0.50 documentation (2024)

Charm has automated the installation process such that youdo not have to directly handle dependencies, linking, and compiler flag settings. Note that these automated installers are available at our repository.However, in the event you are interested in building and installing from source, we have provided installation steps for a number of widely used platforms. If we missed your favorite OS, feel free to write up the instructions and email us at [email protected].

Before we begin, please note the current dependencies:

Python2.7 or Python3
Pyparsing http://pyparsing.wikispaces.com/
GMP 5.x http://gmplib.org/
PBC (latest) http://crypto.stanford.edu/pbc/news.html

Building On Linux¶

Note that the entire compilation process is supported by the Charm configure/make scripts.The steps for building in linux this way are:

In a terminal, run configure.sh
Confirm that you have installed the dependencies above. Then, proceed as follows:
- make
- make install
- make test

Note

Another way to install dependencies is to use your package manager of choice.

Ubuntu 10.04 LTS¶

Before installing Charm, there are a few prerequisites that need to be installed on your system. These are:

Subversion
sudo apt-get install subversion
Python 3 (By default, Ubuntu 10.04 LTS comes with 2.6 and does not officially support 2.7. Charm requires 2.7 or 3.x) and header files/static library
sudo apt-get install python3 python3-dev python3-setuptools
m4
sudo apt-get install m4
libssl-dev
sudo apt-get install libssl-dev

Next, we will install Charm. Navigate to your Charm directory.

We must first run the configuration script:
sudo ./configure.sh --python=/path/to/python3
Now we will build and install Charm:
sudo make
sudo make install
And finally we must rebuild the search path for libraries
sudo ldconfig
Run Pytests
sudo make test

Fedora¶

Before installing Charm, there are a few prerequisites that need to be installed on your system. These are:

m4
su -c "yum install m4"
Python 3 (this is an optional, though recommended, step)
su -c "yum install python3"
Header files/static library
su -c "yum install python-devel" (if you did not install Python 3)
su -c "yum install python3-devel" (if you did install Python 3)
openssl-devel (only necessary if you did not install Python 3)
su -c "yum install openssl-devel"

Red Hat/Fedora has decided not to support ECC in OpenSSL due to patent concerns, so we now need to remove their restriction and manually import the required files.

Remove the ECC restriction
1. Navigate to /usr/include/openssl
  cd /usr/include/openssl
2. Open the OpenSSL configuration file for editing using your editor of choice
  su -c "vi opensslconf-i386.h"
3. Remove the flags that restrict the use of ECC

Delete (at the beginning of file):

#ifndef OPENSSL_NO_EC# define OPENSSL_NO_EC#endif#ifndef OPENSSL_NO_ECDH# define OPENSSL_NO_ECDH#endif#ifndef OPENSSL_NO_ECDSA# define OPENSSL_NO_ECDSA# endif

Delete (later on the file):

# if defined(OPENSSL_NO_EC) && !defined(NO_EC)# define NO_EC# endif# if defined(OPENSSL_NO_ECDH) && !defined(NO_ECDH)# define NO_ECDH# endif# if defined(OPENSSL_NO_ECDSA) && !defined(NO_ECDSA)# define NO_ECDSA# endif

Save the file and close it

Add the ECC files
Navigate to http://www.openssl.org/source/ and download the latest version of openssl source and untar the tar ball.
Navigate to /path/to/openssl-[version]/include/openssl (ie inside the untarred file)
cd /path/to/openssl-[version]/include/openssl
Add the new files to the current OpenSSL installation
su -c "yes n | cp * /usr/include/openssl"

Next, we will install Charm. Navigate to the Charm directory.

We must first run the configuration script:
su -c "./configure.sh"
[If you installed Python 3 and would like to use that, you will need to add -–python=/path/to/python3]
Now we will build and install Charm:
su -c "make"
su -c "make install"
And finally we must rebuild the searchpath for libraries
su -c "ldconfig"

Mint x86_64¶

Before installing Charm, there are a few prerequisites that need to be installed on your system. These are:

Subversion
sudo apt-get install subversion
m4
sudo apt-get install m4
Python 3 (this is an optional, though recommended, step)
sudo apt-get install python3
Header files/static library
sudo apt-get install python-dev (if you did not install Python 3)
sudo apt-get install python3-dev (if you did install Python 3)
libssl-dev (only necessary if you did not install Python 3)
sudo apt-get install libssl-dev
This distro doesn’t seem to come with binutils or gcc make sure you install those.

Next, we will install Charm. Navigate to the Charm directory.

We must first run the configuration script:
sudo bash ./configure.sh
[If you installed Python 3 and would like to use that, you will need to add -–python=/path/to/python3]
Now we will build and install Charm:
sudo make
sudo make install
And finally we must rebuild the searchpath for libraries
sudo ldconfig

Note

Bash to avoid unexpected operator error.

Building in Windows¶

Note that the entire compilation process is now supported by the Charm configure/make scripts. The steps for building in mingw32 this way are:

Download the latest source version of openssl.
Run MinGW Shell.
Extract openssl, configure and install as shown below.
Extract Charm, and navigate to the top directory.
Run configure.sh as shown below.
Confirm that you have installed the dependencies above. Then, proceed as follows:
make
make install

Note

Another way to install dependencies is to follow the Windows blocks below.

MinGW32¶

Let’s first build our dependencies with the following scripts:

To build the GMP library:

./configure --prefix=/mingw --disable-static --enable-sharedmakemake install

To build the openssl library:

./config --openssldir=/mingw --shared # This gets us around installing perl.makemake install

To build the PBC library:

./configure --prefix=/mingw --disable-static --enable-sharedmakemake install

To build the Charm library:

./configure.sh --prefix=/mingw --python=/c/Python32/python.exe

Building in Mac OS X¶

Leopard v10.6¶

Note that the entire compilation process is supported by the Charm configure/make scripts. The steps for building in os x this way are:

In a terminal, run configure.sh
Confirm that you have installed the dependencies above.
The next steps may require super user privileges so prepend a sudo to each command:
make
make install
make test

Note

Another way to install dependencies is to use macports or fink.

Lion v10.7 and Mountain Lion v10.8¶

In Lion, Apple has made the decision to deprecate the openssl library in favor of their Common-Crypto library implementation. As a result, you’ll have to make some modifications to the library in order to use it with Charm. Please follow the steps below then proceed to install Charm:

Edit the crypto.h header file at /usr/include/openssl/crypto.h
Add the following before the crypto.h header definition:

#pragma GCC diagnostic ignored "-Wdeprecated-declarations"#ifndef HEADER_CRYPTO_H#define HEADER_CRYPTO_H

Next, we can install Charm. Run the configure script as before, but due to some changes in the default compiler installed we have provided a command line option to account for these changes:
./configure.sh --enable-darwin
The next steps may require super user privileges so prepend a sudo to each command:
make
make install
make test
