Hello everybody,

I am working with the code.

I clone the repo, and make a pull upstream of github's cpython repository (master branch), and when I make:

./configure --with-pydebug && make -j

build correctly but finished with this message:

Failed to build these modules:
_ctypes   

But the Test Result is: SUCCESS

Regards

Are you using Ubuntu or other Linux distribution? This problem is because you didn't install the dependency package.

You may first try to use the instruction at devguide:
http://cpython-devguide.readthedocs.io/setup.html#build-dependencies

Or, assume you have install build-essential and python3-dev ...etc., maybe you lost to install libffi-dev, just simply apt-get install libffi-dev and rebuild to solve this problem.

The problem was solution making:

apt-get install libffi-dev

Thanks

In centos, sudo yum install -y libffi libffi-devel should worked
