Whichever type of operating system did you use and what OpenSSL version did you have? Also what do you mean with latest version?
Ah yes, Ubuntu 16.04, OpenSSL 1.0.2p, from the main repo.
https://github.com/vergecurrency/electrum.git
On a side note, I was wondering if this, if you don't specify a datadir with -D, it overwrites existing .electrum/ datafolders. If so, might be an idea to change the name.
You will need at least OpenSSL 1.1 to run this version of electrum. Everything lower is also already discarded by OpenSSL themselves :)
And actually it does create a new folder under „electrum-xvg“, but can actually double check that
Hm. Since I have no need for an electrum wallet, I guess this was my testing contribution. Not going to manually install a second ssl version. Thanks for the answers, closing.
