$> brew install openssl
$> brew install swig
$> env LDFLAGS="-L$(brew --prefix openssl)/lib" \
CFLAGS="-I$(brew --prefix openssl)/include" \
SWIG_FEATURES="-cpperraswarn -includeall -I$(brew --prefix openssl)/include" \
pip install m2crypto

perfect！！

it works for me, thanks.

If you accidentally (or purposefully) you have another version of OpenSSL these are the correct commands:

brew install openssl@1.1

env LDFLAGS="-L$(brew --prefix openssl@1.1)/lib" \
CFLAGS="-I$(brew --prefix openssl@1.1)/include" \
SWIG_FEATURES="-cpperraswarn -includeall -I$(brew --prefix openssl@1.1)/include" \
pip install m2crypto

 include/sys/_types/_int8_t.h:30: Error: Syntax error in input(1).
    error: command 'swig' failed with exit status 1

You need to make sure a real gcc (not /usr/bin/gcc, which is clang) installed. Otherwise it uses clang to build the package.

_m2crypto.so' (mach-o file, but is an incompatible architecture (have (x86_64), need (arm64e)))

Any solution?

Worked for me (Intel Mac Ventura, openssl@3). I set the environment and to get the right Python I used python3 -m pip install m2crypto
