23:36:01@dan5865:matrix.orgdan5865with PICOPS closing down - does that invalid the KYC done during the polkadot ico?

01:08:05@repj:matrix.orgrepj dan5865: Verification took place at the time.

rphmeier: thanks. I updated my compiler, but now getting this error:

error: failed to compile polkadot v0.1.0 (https://github.com/paritytech/polkadot.git?branch=v0.1#6fe12237), intermediate artifacts can be found at /var/folders/2_/.../T/cargo-installfSnx71

Caused by:
Could not compile polkadot.

09:36:23@test12312:matrix.orgtest12312Have you seen this before? I did some googling, but the closest I can find is https://github.com/spacejam/rust-rocksdb/issues/159 which is unresolved. On OSX 10.13.4
09:37:58@tomaka17:matrix.parity.iopierre-tomaka test12312: Could you upload the entire logs on pastebin or something similar?
09:38:14@tomaka17:matrix.parity.iopierre-tomakaI mean, the entire error message
09:42:57@edwardt:matrix.orgedwardtI figure we should probably have a polkadot technical support channel. That way devs / community can help each other getting the code to compile.
09:44:22@edwardt:matrix.orgedwardtplus other technical / practical issues.
09:48:04@test12312:matrix.orgtest12312 pierre-tomaka: sure, 1 sec, it's too big to fit into my terminal window, so will just have to re-route the output into a file

now if you can figure out a way to have pluggable consensus Po* all within the same interoperating network... that would be cool af

In case anyone was curious, Rob pointed out that it could be possible to have a PoW rule for validation.


09:55:49@test12312:matrix.orgtest12312 pierre-tomaka here's my install log https://pastebin.com/X4LEEMRp
10:07:54@tomaka17:matrix.parity.iopierre-tomakaDidn't realize you were on OSX
10:08:52@tomaka17:matrix.parity.iopierre-tomakaIt fails to link libstdc++, but don't know why
10:09:21@tomaka17:matrix.parity.iopierre-tomaka(because I don't know anything about OSX)
10:10:05@keno:matrix.orgkeno Keno:
Hello @everyone, I think it would be great to meet some of you, maybe have some drinks and talk about Polkadot and crypto in general. For everyone in beautiful Berlin I created a telegram group specific for that purpose. 😀 https://t.me/joinchat/GfqTDkb6A7R7XUC5n9_U2A
10:10:59@genevieverenoir:matrix.orgGenevieve🌸  changed their profile picture.
10:13:27@test12312:matrix.orgtest12312Fair enough - has anyone successfully built polkadot on OSX?
10:32:45@tomaka17:matrix.parity.iopierre-tomakaMy guess would be that it's building with g++ instead of clang and erroneously linking libc++ instead of libstdc++
10:53:27@jacogr:matrix.parity.ioJaco test12312: Yes, Gavin, Rob, Arkardiy & myself are all actually on OSX. So it does build & run without issue, however not sure what is missing in your case. (Hopefully one of the Rust guys have an idea)
19:58:01* @keno:matrix.orgkeno added a riot room bridged to the telegram group :) riot.im/app/#/room/#polkadot_berlin:matrix.org

05:06:05@repj:matrix.orgrepj😆 go keno!
08:52:26@mikedge:matrix.orgmikedge joined the room.
09:47:04@test12312:matrix.orgtest12312 Jaco: pierre-tomaka : Got it working! pierre-tomaka's comment led me on the right path - upon further investigation of my gcc binary I realised it was not using the default osx version. Turns out a recent install of the python package manager Anaconda had added gcc -> <home>/anaconda3/bin/gcc to my path. Removing Anaconda from .bash_profile fixed the issue! Apparently the above is the default Anaconda behaviour, so probably not the last person to run into this problem :)
17:38:52@repj:matrix.orgrepj Dot Daily-- Anyone want to chat substrate consensus? Rob went over the dual mechanism (Aurand (Single staked validator) for growth and PBFT (2/3+) for finality) in his presentation last week (https://www.youtube.com/watch?v=q1zLHO7Lkuk). Any thoughts on this versus attempts to date, potential benefits and risks? :)
