Problems with secp256k1 #7

Closed maxcado closed 5 years ago

maxcado commented 5 years ago

Hello, I'm trying to use your code. It looks pretty well organized. Thanks for sharing. I've installed it on a linux and Windows machine but had some issues installing on Windows. There were errors regarding no secp256k1 and no pkg-config. I managed to get it installed but now when I use some code taken from https://pybtc.readthedocs.io/en/master/_modules/pybtc/functions/bip32.html#private_from_xprivate_key I get the following message:

Traceback (most recent call last): File "C:\Users\user\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\pybtc-2.0-py3.7.egg\pybtc\xprv-to-prvkey.py", line 4, in from secp256k1 import ffi ModuleNotFoundError: No module named 'secp256k1'

How can I effectively manage pybtc to get all modules working properly so I can make use of the code.

Please install secp256k1 module: pip3 install secp256k1

I've tried installing the module secp256k1 using pip3 and I get this message: 'pkg-config' is required to install this package. Please see the README for details.

What is pkg-config?

4tochka commented 5 years ago

For Ubuntu/Debian OS,

apt-get install -y pkg-config

For Redhat/Yum OS,

yum install -y pkgconfig

4tochka commented 5 years ago

Mac OS brew install pkg-config

What about the Windows platform? That is where the problem with installation occurred.

What about the windows platform?

Sorry for bothering, I meet the same problem. But it seemed that install msys2 or mingw-w64 on windows and install pkg-config package in mingw-w64 will solve this issue on windows.
