Answer 1

M2Crypto (as of version 0.26) does not officially support Python 3. Officially supported Python versions are:

Programming Language :: Python :: 2.6
Programming Language :: Python :: 2.7

The issue you're having is same as described in https://gitlab.com/m2crypto/m2crypto/issues/114#note_13223251

You can find out which popular libraries are compatible with Python 3 at http://py3readiness.org/

Answer 2

We are able to use m2crypto on Python 3 with following global packages libssl-dev swig python3-dev gcc

so

sudo apt-get install libssl-dev swig python3-dev gcc

should allow install m2crypto via PIP for Python 3 (tested on version 0.32)

what would be the solution for the windows system. – Barbellate

This works for me. after doing that, i run the command: python3 -m pip install ... – Triploid

Answer 3

Steps in MAC for python3.X:

First Install.

brew install openssl

Second Swig

brew install swig

Change the SWIG_FEATURES

CFLAGS="-I$(brew --prefix openssl)/include" \
SWIG_FEATURES="-cpperraswarn -includeall -I$(brew --prefix openssl)/include" \
pip install m2crypto```

I'm getting the following error: /Library/Developer/CommandLineTools/usr/include/c++/v1/stdint.h:123: Error: Unknown SWIG preprocessor directive: include_next (if this is a block of target language code, delimit it with %{ and %}) error: command 'swig' failed with exit status 1 – Helvetia

Great answer... Fix to the point... – Watusi

Answer 4

I had this error on python 2.7.

This happens when the c dependencies for python aren't available and pip attempts to install and compile a package that has a c extension.

sudo apt-get install python-dev

This resolves it for me.

After this install M2Crypto

pip install m2crypto

Answer 5

On Mac do the following

$> brew install openssl
$> brew install swig

Now add these lines to your ~/.zshrc file on Mac OS X

# this is very slow, see https://github.com/Homebrew/brew/issues/3327
# OPENSSL=$(brew --prefix openssl)
# this is much faster
# OPENSSL=$(dirname $(dirname $(which openssl)))
# hardcoding is fastest
OPENSSL=/usr/local/opt/[email protected]
export PATH="$OPENSSL/bin:$PATH"
export LDFLAGS="-L$OPENSSL/lib"
export CPPFLAGS="-I$OPENSSL/include"
export PKG_CONFIG_PATH="$OPENSSL/lib/pkgconfig"
export SWIG_FEATURES="-cpperraswarn -includeall -I$OPENSSL/include"

Then in a new terminal do

$> pip install m2crypto

Answer 6

Here we go, this works 100%

apt install python2.7
python2.7 -m pip install M2Crypto
