Bug 557080 – net-p2p/cpp-ethereum: ebuild request

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description A. Person 2015-08-08 21:38:47 UTC]

Ethereum was just released (it's a big deal):

https://ethereum.org

This bug is a request for an ebuild for ccp-ethereum:

https://github.com/ethereum/cpp-ethereum

I followed the build instructions here:

https://github.com/ethereum/cpp-ethereum/wiki/Building-on-Ubuntu#choose-your-source

I was able to get through cmake successfully:

cmake .. -DCMAKE_BUILD_TYPE=Release -DBUNDLE=minimal -DETHASHCL=0 -DEVMJIT=0 -DMINER=0

By installing the following:

leveldb
rocksdb
v8
libjson-rpc-cpp

But make fails:

In file included from /root/cpp-ethereum/libdevcore/CommonIO.h:39:0,
                 from /root/cpp-ethereum/libdevcore/CommonIO.cpp:22:
/root/cpp-ethereum/libdevcore/Common.h:87:2: error: unused parameter '_c' [-Werror=unused-parameter]
  secure_vector(secure_vector<T> const& _c) = default;
  ^

  return ret;
         ^

Oh and the cpp-ethereum ebuild in an overlay fails for me.

You referred to http://gpo.zugaina.org/net-p2p/cpp-ethereum?

Yes, that one won't build for me.  I was able to build cpp-ethereum myself by removing -Werror from cmake/EthCompilerSettings.cmake and invoking cmake like this:

cmake .. -DCMAKE_BUILD_TYPE=Release -DBUNDLE=minimal -DETHASHCL=0 -DEVMJIT=0 -DJSCONSOLE=0

The only extra dependencies I had to install were leveldb, v8, and libjson-rpc-cpp.
