Im trying to crate a cryptosystem on the raspbian OS. Chose python and pycrypto because the OS comes with python 3.2.3 pre-installed. Moved the "pycrypto-2.6.1.tar.gz" to the folder where python files are located and extracted there. Suposed to build using the command "python setup.py build" and then install.
But during the build phase, keep getting the error:
"pi#raspberrypi /usr/lib/python3.2/pycrypto-2.6.1 $ python setup.py buildrunning build
running build_py
running build_ext
running build_configure

"
Not able to figure out whether I am supposed to change the pathing. Could somebody give an insight in to this?
warning: GMP or MPIR library not found; Not building Crypto.PublicKey._fastmath.
The libgmp-dev package provides the necessary files to support building the optimized module here:
apt-get install libgmp-dev
src/MD2.c:31:20: fatal error: Python.h: No such file or directory
compilation terminated.
If you search for fatal error: Python.h: No such file or directory, the very first Google result is for this StackOverflow question, which tells you that you need to install the python-dev package:
apt-get install python-dev
In general, if you are building software from source you will need the corresponding -dev package for any required libraries; these packages provide header files (foo.h) and the unversioned shared libraries necessary for linking.

Calling
pip install SQLAlchemy
I get an error:
lib/sqlalchemy/cextension/processors.c:10:20: fatal error: Python.h: No such file or directory
As far as I know, I have the correct Python version (2.7.3) and OS (Ubuntu 12.04) (See below.) for this to work. Am I doing anything wrong?
The install does work as
pip install --global-option='--without-cextensions' SQLAlchemy"
but I want the C extensions.

You need to install the python-dev (or similar name) package for your version of Python. It includes all the header files needed to compile C extensions. These files are (unfortunately) not included in the default python packages.
For Ubuntu, the command is
sudo apt-get install python-dev
or
sudo apt-get install python3-dev
depending on which version you're using.
sudo apt-get install python-dev -y

I am using Python 2.7, I have MinGW and Cygwin installed on the system. I tried to google it. But there isn't a similar problem.
I used mingw-get-inst-20120426.exe to install the MinGW version 4.5.
-mno-cygwin in Python\Lib\distutils\cygwinccompiler.py causes this problem: see Compiling with cython and mingw produces gcc: error: unrecognized command line option '-mno-cygwin' or http://korbinin.blogspot.com/2013/03/cython-mno-cygwin-problems.html. My Python distribution (Anaconda)'s cygwinccompiler.py does not have that though. Anyway, after removing all -mno-cygwin in the definition of the Mingw32CCompiler class you should be able to compile.

Any help or clue?
Unfortunately, pymssql's setup.py (as of version pymssql-2.0.0b1-dev-20111019) needs a bit of help to work properly on OSX Lion. The current setup.py tries to compile/link against some pre-built Linux FreeTDS libraries, and also tries to link against librt, which doesn't exist on OSX. Additionally, it only explicitly looks for FreeTDS libraries from Fink or MacPorts, so if you've installed Homebrew (if you use if) or FreeTDS itself in a non-standard location, it may not be located by compiler/linker.
I created a repaired version of setup.py here. It worked well enough for me with the Homebrew build of FreeTDS using the standard locations (/usr/local/{lib, include}), but as always YMMV. You may need to adjust setup.py further if you've installed FreeTDS in a different location. You can generally ignore the warnings from the linker about missing directories that may not exist on your system:
ld: warning: directory not found for option '-L/usr/local/lib/freetds'
One other note: You will probably have built FreeTDS for a single architecture, likely x86_64. By default, pymssl will be a multi-architecture build (assuming you're using the system Python 2.7.1), so even with a patched setup.py you will see a linker warning something like:
ld: warning: ignoring file /usr/local/lib/libsybdb.dylib, file was built for unsupported file format which is not the architecture being linked (i386)
That warning just indicates that the FreeTDS libraries only have single architecture version to link against. You can avoid the warning by using ARCHFLAGS to make a x86_64-only build:
ARCHFLAGS="-arch x86_64" python setup.py install
Or, try this fork, it installs without issues:
https://github.com/blackbass1988/pymssql-macos-lion
To install on OS X Mavericks, you need
OS X Command Line Tools
FreeTDS
brew install freetds
Cython
pip install cython
and then finally you can install the pymssql-macoslion
pip install git+git://github.com/blackbass1988/pymssql-macos-lion.git#master
Just incase anyone is reading this the following worked for me:
brew install freetds
sudo pip install pymssql

I have installed python-dev tools already.
You are missing the Python development libraries. (Try apt-get install python-dev.)
However, unless you have a valid reason to compile pycrypto yourself, just install it via (I think) apt-get install python-crypto.
Question
How do I install SSL for Python 2.5 on Debian?
I have tried:
sudo easy_install ssl
But getting:

error: command 'gcc' failed with exit status 1
Solution
sudo apt-get install libbluetooth-dev
sudo rm /usr/lib/python2.5/site-packages/ssl/__init__.pyc
For reference, you must install libbluetooth-dev.
In fact, you shouldn't compile your own version of python ssl module for several reasons:
you won't get automatic security updates of your python ssl module;
you won't get smooth upgrade path if you decide to upgrade Debian system on your server.
The best way to obtain python ssl module is to install it from official Debian repositories using apt-get:
apt-get install python-openssl
Hope this helps.
