How do I install M2Crypto on Ubuntu?

Question

I'm trying to build and install M2Crypto on Ubuntu 10.04 LTS. I downloaded and untarred M2Crypto-0.20.2.tar, and from the M2Crypto-0.20.2 directory I tried python setup.py build. I got an error because I don't have swig. So I ran sudo apt-get install swig. Then I tried python setup.py build again and got:

...and so on.

Has anyone succeeded in doing this?

Update: I changed the title, since it didn't occur to me that M2Crypto would be a pre-build Ubuntu package.

That just didn't occur to me. It worked just like it should. If you put your comment in an answer I'll accept it. – Garthgartner

Answer 1

You probably need to install the python development packages:

sudo apt-get install python-dev

Better yet, don't bother building m2crypto yourself. It's already in the Ubuntu repositories as a fully supported package. This way, you'll get automatic updates through the same means as the rest of your Ubuntu system:

sudo apt-get install python-m2crypto

Unfortunately, M2Crypto hasn't been ported to Python 3, yet :( – Parquetry

Answer 2

do you have the python2.6-dev package installed? this is the package that contains the Python.h file you are missing

Answer 3

Maybe someone will get openssl related errors, try this:

sudo apt-get install openssl
sudo apt-get install libssl-dev
