I would like to install cpp-ethereum following the documentation

Powershell is running in admin mode, but if I try to run the install command (choco install cpp-ethereum), I get this error:

PS C:\WINDOWS\system32> choco install cpp-ethereum
Chocolatey v0.10.8
Installing the following packages:

The same error message can be found in the log. What does this error message mean and how is it possible to fix it?

What does this error message mean and how is it possible to fix it?

It means the package does not exist.

So you can either use Ethminer which gets it's origins from cpp-ethereum or download the source to cpp-ethereum then use that. It also appears that: AlethZero Stable 0.8.2.3-POC8 is a compiled version of cpp-ethereum. Of course that particular project has not received a single update in 3 years.

The ethminer is an Ethereum GPU mining worker. It origins in cpp-ethereum project (where GPU mining has been discontinued). Then hugely improved in Genoil's fork.

ethminer 0.11.0

Here is how I know it doesn't exist:

Search for "cpp-ethereum" returned 0 packages

Source

Going directly to the package url also doesn't show a package:

Cpp-Ethereum

it possible to fix it?

If you can find another Chocolatey source I suppose you could add it and then install it or you can just compile from source or use something else but otherwise you cannot fix it because the package no longer exists.

You can also maintain your own package internally and/or on the community package repository.

The provided link in your question, clearly indicates, they have not supported Chocolatey in a very long time (if ever).

  • As a clarification point - the package was not removed by the moderators/community, it never existed. You could go directly to the package page at chocolatey.org/packages/cpp-ethereum and see a hidden package if it existed. There isn't one.

  • @ferventcoder - I am not sure it really matters. It doesn't exist today. So an alternative must be used if the author wants to use Chocolatey to install a similar package.

  • I just wanted to be clear on that one point. I read the link, and I don't know if the group ever maintained a Chocolatey package on the community repository. If they did, it certainly wasn't under the name cpp-ethereum. One by that name never existed - one named ethereum was submitted by a community member but it never made it past moderation. So I'm not really sure what they meant by "though we have done so in the past."

  • @ferventcoder - Understood. Adding the clarification it never existed just isn't a huge priority when it does not really make a difference to my actual answer.

  • I did provide an edit - the edit also points out that the OP can create and maintain an internal package and that they can also make a package available on the community package repository if they would like to do that as well - two additional options for fixing the issue.
