Issue Type

[x] bug report
[ ] feature request

Current Behavior

Cannot build the source code, although I made sure that:

  • I have leveldb correctly installed (via homebrew) and there's a link in /usr/local/include
  • I ran xcode-select --install and when I run gcc -v I correctly see /usr/local/include mentioned there

Expected Behavior

make should work.

Steps to Reproduce

This is perhaps a problem specific to OSX.

  1. git clone git@github.com:omisego/plasma-mvp.git
  2. virtualenv env -p python3
  3. source ./env/bin/activate
  4. make

I managed to get it working:

Without virtualenv

I had to reinstall openssl and follow the instructions from here: ethereum/pyethapp#209. Afterwards, the install ran smoothly.

With virtualenv

I switched to pyenv and pyend-virtualenv and, after fiddling with the tools for a while, I managed to run make successfully inside the environment. Of course, tests don't work but I see that there are already PRs for that.

Did this happen just to me? I might update the README to add some warnings for OSX. Considering the latest developments of Plasma (Cash, Debit et al), is OmiseGo still working on the mvp?

Weird. I haven't seen this issue yet. I guess if it's working now I'll close (?).

Yup! I just wanted to make sure it was something with my machine. Thanks!
