How to install Charm-crypto library for python3 on windows 10?

Question

I've installed GMP 5.x , PBC (latest) and OPENSSL but when I try `pip3 install charm-crypto this error occurs. If anyone knows how to solve this error because I don't understand it please tell me? By the way the error is much longer than this but I couldn't paste it, It is mostly repeating the process of copying

Answer 1

The problem is there is file with code which is not compatible with MSVC. sys/time.h is included in benchmarkmodule.h and unfortunately this file does not exit in MSVC.

Try to install mingw, set the CC to mingw compiler and run the pip3 command . If it still not working you can try to build it directly like explained in https://jhuisi.github.io/charm/install_source.html .

In all cases you will need a mingw compiler. However, it may be complicated.
You will need to install the msvc redistributable. When you run the make command, f you face the error Unknown MS Compiler version 1927 . modify the cygwinccompiler.py file by adding :

#custom add
elif msc_ver == '1927':
    # VS2019 / MSVC 16.7
    return ['msvcr100'] 
#custom add

before the last add. You may also need to add a file distutils.cfg like explained in https://wiki.python.org/moin/WindowsCompilers . Once these modifications done, the compilation should start normally.

Perhaps the easiest would be to compile it under linux.
