Bug: cannot use pycrypto with python3.11

[mims92]

Description:

When trying to build/test an 3.11 Python application that requires pycrypto, there is this issue:

[...]
    gcc -pthread -Wsign-compare -fwrapv -Wall -fPIC -std=c99 -O3 -fomit-frame-pointer -Isrc/ -I/usr/include/ -I/var/lang/include/python3.11 -c src/_fastmath.c -o build/temp.linux-x

                ^~~~~~~~~~~~~~~
      compilation terminated.
      error: command '/usr/bin/gcc' failed with exit code 1
      [end of output]

The issue doesn't occur with Python3.9 image.

Steps to reproduce:

1. Create an application with SAM using Python3.11 runtime
2. add pycrypto in the requirements.txt file
3. Build the application

Observed result:

      error: command '/usr/bin/gcc' failed with exit code 1
      [end of output]

Expected result:

The application build correctly.

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Docker
2. If using SAM CLI, sam --version: 23.1.2
3. AWS region: /

Hi there,

It looks like it is trying to compile the c bindings and it is failing with new python3.11 image. It is probably caused by gcc version (or other libraries related to gcc). Some python libraries provide their compiled c bindings but for this one, it needs to be compiled from scratch.

When I search for the library it seems that it is not been maintained anymore, so I assume it is not updating its source code for newer tools https://www.pycrypto.org/

You can create your own image which will contain a combination of the python version you need and the other tooling that this library requires. And then you can provide the custom image during build with --build-image option. Or, you can also create and Image based Lambda function which then can be build from different base images.
