Pycrypto install fatal error: gmp.h file not found

Question:

It seems like there are a number of people who have had a similar problem, however, after much searching I haven’t been able to find a solution that works with my particular architecture. I’m trying to install Pycrypto (as a subsidiary of Fabric) to no avail.

I’m running Mac 10.8.2, python 2.7.3 via Homebrew, and XCode 4.6 — installing with pip or easy_install (I’ve tried both). From what I can tell, the problem could either be with respect to my version of XCode or because of my libraries. The Command Line Tools for XCode have been installed and I have tried placing setenv ARCHFLAGS "-arch i386 -arch x86_64" in my .cshrc file. I have also tried ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer. As for the libraries, I’ve tried linking them via ln -s /usr/local/lib/libgmp.dylib /usr/lib/libgmp.dylib – but that also didn’t work.

The error is always the same (see below) no matter what angle I attempt. Any and all help would be appreciated.

Answers:

Simply linking gmppylib is not helpful because pycrpto needs to compile some C files which will include gmp.h. You should have the GMP library installed which will contain gmp.h. It seems you have to install GMP on your Mac OS. The following two links should be helpful to you.

I finally realized that the root of my problem was in an incompatibility between the versions of Fabric and Pycrypto. Once I downgraded my version of Fabric to 1.2.6, I no longer got the errors above. Then, I used the tutorial as a jumping off point. However, despite the tutorial and the older version of Fabric, I still got the PyCrypto >= 2.1, !=2.4 error. I eventually installed Pycrypto 2.2 from source (since apparently pip will only install v. 2.0.1 even when designating pip -Iv install pycrypto==2.2 per this and v. 2.6 resulted in the gmp.h error). Finally, everything worked.

Here is the fix that worked for me:

You need to create a symlink based on the installation header include path (-I) in but crash. Example:

I was able to get PyCrypto to install using the following command:

CFLAGS=-I/opt/local/include pip install pycrypto

I have GMP installed via MacPorts, running on OSX 10.8.3 with Python 2.7.2 from python.org. In this case I am installing into a virtualenv.

I do get the following warning when PyCrypto is used, but it still works:

/Users/me/.virtualenvs/blah/lib/python2.7/site-packages/Crypto/Util/number.py:57: PowmInsecureWarning: Not using mpz_powm_sec.  You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.
  _warn("Not using mpz_powm_sec.  You should rebuild using libgmp >= 5 to avoid timing attack vulnerability.", PowmInsecureWarning)

If you use Homebrew, this should do the trick:

brew install gmp
env "CFLAGS=-I/usr/local/include -L/usr/local/lib" pip install pycrypto

Using env will only make it work for that invocation. If you need to install pycrypto at a later time in this session export the variable instead.

export "CFLAGS=-I/usr/local/include -L/usr/local/lib" 
pip install pycrypto
